The function of drilling fluid and importance of solids control products

The modern drilling indispensable to use the circulating fluid, in addition to a small amount of circulating fluid is the use of gas and foam, the vast majority ofcirculating fluid drilling are used in liquid, so called circulating fluid used in the process of drilling for drilling fluid. Because the drilling fluid early just mixed liquidclay and water, almost no other chemical composition, oil field used to be called “mud”.

Drilling fluid plays an important role in the process of drilling. Its main function has:

1) cleaning the bottom

Cutting rock resulting in a large number of cuttings in the drilling process, the cutting is by drilling fluid to remove the continuous cycle. If the debris can not be promptly removed, it will be repeated fragmentation, will affect the further drilling rock drill.

2) cooling, lubricating the drill bit and drill string

In the process of drilling, drill bit for drilling pressure load to bear on the very serious, resulting in bit bearing and bit working surface heating. At the same time,because of the drill string friction constantly in the process of rotating with the wall, not only to generate heat, but also accelerates the drill string wear, power consumption is increased, and the drilling fluid can pass through the loop carries heat away in time, cooling of drilling, but also to the lubrication, so as to reduce the side effects produced by friction.

3) the formation of mud cake, protect wall

The formation of deep rock in three-dimensional compressive state due to the top and the surrounding rock pressure. When after drilling, borehole surrounding rock must bear the extruded from all directions and generates a stress incrementvalue, i.e., stress concentration. In this case, if the wellbore rock strength is not big enough, it may lead to the wall collapse. But if the containing increasing agent, filter loss of drilling fluid action low around the borehole wall, will make up the rock stress decreases, so that the ”compression collapse” to reduce the chances. But the density of drilling fluid can not be too large, otherwise it will lead to the rock’s “fractured broken”, causing the leakage of drilling fluid. And by adding various additives in drilling fluid has formed a layer of mud cake on the borehole wall will in the cycle process, mud cake quality can not only protect thewall is not drilling fluid erosion, but also can reduce the leakage of drilling fluidinto formation.

4) control and balance formation pressure

When drilling into the high pressure oil (gas) layer, if the formation of oil (gas)reservoir pressure higher than that of drilling fluid column pressure, will happen “blowout” led to drilling accident. This should be the preparation of drilling fluid density appropriate, make the drilling fluid column pressure is equal to the(usually slightly greater than) the formation pressure, so as to ensure the safeand fast drilling. But the density is not too large, otherwise it may put the oil (gas)layer blocked.

5) floating debris and weighting agent

In the process of drilling, drilling fluid, flow in the annular space of the wellboremay not be too high, and the water because of low density makes the suspensionability is poor, as the debris and weighting agent in drilling fluid circulatingdischarged from the ground, but also to join the other various additives to increase the suspension ability.

6) the geological data to provide the drilled strata

Through drilling fluid sampling on out of the ground of the analysis, can obtain the drill data of lithological and stratigraphic oil gas content.

7) the water power is transmitted to the drill bit

Drilling fluid from the bit nozzle flow to the bottom, not only clean cuttings, but also lower the energy to bottom auxiliary rock breaking, jet drilling is a drilling technique using bit hydraulic power. Proof of drilling practice at home and abroad, jet drilling technology to improve drilling speed, and reduce the drilling cost.

8) removal of drill cuttings on the ground

Solid particles are dispersed in the drilling fluid called solid from drilling fluid.Solid phase in drilling fluid, one is from cuttings, two is to meet the requirement of the drilling technology and adding the man-made

According to the solid phase in drilling fluid action can be divided into two categories:

A class is a useful solids such as bentonite, chemical treatment agent and bariteetc.;

Another kind is the harmful solid, such as cuttings, inferior bentonite, sand etc..The so-called solid drilling fluid control is to remove harmful solid, retain theuseful solids or solid content and total level of granularity in the drilling fluidcontrol scope required in drilling process inside, to meet the requirements ofdrilling fluid properties of drilling process. Usually, the drilling fluid solid control process referred to as solid control, oil field is used to be called mud purification.

Mud gun in Drilling Oil Rig System

Simple introduction on mud gun

The mud gun also can be called Mud mixing gun. It is usually used along with mud agitator as mixer for oil rig system.

Mud gun is consisted by main construction by steel pipe and flange, the valves including high pressure or low pressure and the rotary.

And the different oil rigs have different mud system, such as different on treating capacity, different on mud tank cap acity, difference on mud properties, ect. Then mud guns should hold relative height, etc.


The mud gun is simple in design or structure. Usually all turning takes place on double rows of steel balls in flame hardened races. There is nothing to tighten or adjust. Flow is unrestricted and pressure drop is minimum.

Mud gun types

1. Divided by pressure: there will be high pressure and normal pressure;

2. Divided by rotary type: there will be with manual rotary or fixed type;

3. Divided by diameter: there will be NJQ50 and NJQ80;

4. Divided by nozzle number: there will be single one and triple one, etc;

5. Divided by valves: there will be gate valve type and butterfly valves type.


Mud gun in Drilling oil rig system

Mud gun as we said, it will be used together with mud mixers. And the mud resources to mud gun is given by mud pump in oil rig. The mud gun can mix or spray mud to dead angles. This will make mud more even and better effect than mud agitator.

Moreover, the mud gun in Oil rig system also have normal pressure and high pressure. This is according to client’s demand. Different oil rig will request different mud gun. Please go and contact OGEM.

A Drilling Mud Solids Control System Contains Five Stages

It’s well know that solids content has influence on drilling process. Then, how to make the oil or gas drilling process better? The answer definitely is using solids control system to control the solid content. But what is the solids control? Let’s have a look together.
According to the different medium, mud is divided into water-based mud, oil-based mud and emulsion mud. According to the need of different strata and drilling design, reasonably select drilling mud system is a necessary condition for fast, high quality, safe drilling.

Drilling Mud Solids Control System

Solids control is a technique used in a drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally, a solids control system contains five stages: the mud tank, oilfield drilling shale shakervacuum degasserdesanderdesilter, and centrifuge. The shale shaker is used to separate big solids with diameter above 76μm, the desander addresses solids from 47-76μm, and the desilter segregates solids between 12-47μm. Sometimes the desander and desilter are combined as one high efficiency mud cleaner. When air enters the drilling fluids, a vacuum degasser is used to separate the air. If no air is found in the mud, the degasser would work as a big agitator. All these stages are mounted on the top of the mud tank. After separating the solids, the clean mud can be pumped into the borehole again.

Shale shaker, hydrocyclones and oilfield decanter centrifuge are three essential solids control equipment in the process of drilling, play very important roles in solids control if reasonably combined, can use chemical flocculation mud to make solids control more effective in order to ensure the safety, high quality and fast drilling mud performance. Comparative analysis of the working principle, cleaning efficiency, scope use of the solids control equipment, select solids control equipment according to the specific requirements of solids control process parameters are calculated, to achieve the best matching effect.

The solid phase in mud is divided into active and inert or useful and useless, reasonable mud solid content in slurry can make the drilling speed to achieve the best effect; reasonable control of mud solid type can make the mud properties to achieve the best effect.

It is mainly used to improve the quality of materials, machining process, machining precision of general matching oil drilling mud equipment.

HDD: Horizontal Directional Drilling Features

Horizontal directional drilling 

Horizontal directional drilling will neither impede traffic, nor destry green vegetation. The normal work order of shops, hospitals, schools and residents will not be disturbed by the drilling operation. Therefore, we could say that HDD avoid the interference brought by traditional excavation and construction to citizens living, traffic, environment.

Modern horizontal drilling equipments are of high precision. It is easy to adjustment the direction and depth of laying. Long distance laying of pipeline could fully meet the design requirements for depth, and make the underground pipeline bypass obstacles.

Urban pipeline networks generally reach 3m depth, while across the river, generally 9-18m depth under the riverbed. So, the use of horizontal directional drilling will not bring impact on the surrounding environment. Without damaging the landscape and the environment, HDD adapt to various environment requirements.

XJ350 Workover rig-for reference

While carry out horizontal directional drilling, there are no water surface & underwater job involved. So, navigation on rivers will not affected and no damage brought to river embankments on both sides. HDD construction is with the features of short construction period, fewer personnel, high success rate as well as no limitation by season.

Compared with other construction methods, HDD is fast getting into and out of site. And the construction sites can be flexibly adjusted. Especially in urban construction, its advantages would be fully displayed as small construction area requested and low construction cost, but high speed.

In horizontal drilling through large river, due to pipeline buried under the ground surface with depth to 9-18m, the formation of oxygen and other corrosive matters are very little there, the pipeline could be live longer under the function of natural anti-corrosion and insulation.
