Common Problems and Possible Cause of Drilling Desilter

Oilfield drilling desilter is the third stage of oilfield solids control equipment.

In oilfield solids control system,the solids with diameter ranging from 12 to 47

μm are to be separated from the rest,which will go through further processing.

The Oilfield drilling desilter is the third stage equipment in the whole drilling mud

system, at the same time, it is an important device, too. Let’s see some common

problems and solutions for that .

Common Problems

(1) Repeated plugging of Apex in all cones.

(2) One or more cones plugging while others are working normally.

(3) Cones are loosing whole mud in stream.

(4) Solids content in cone overflow continues to increase over time.

(5) The underflow discharge is very dry.

(6) Hydrocyclones leak between the cone nut and body, but no fluid is coming out of the bottom.

Mud Drilling Equipments-JBQ Series Mud Mixer

JBQ series mud mixer,is combine venturi tube and jet nozzle into a new type of jet injector device, not only has simple structure, but a strong feasibility.
JBQ series slurry device is mainly used to formulate or increase the amount of drilling fluid, the special equipment to change density of drilling fluid viscosity and water features.
To change the drilling fluid properties, first need to put drilling fluid materials (bentonite and barite powder, etc.) and the corresponding chemical additives (polymer, etc.) into circulation tank. If direct investment can lead to drilling fluid material and chemical mixed unevenly, which seriously affect the quality of the drilling fluid
The slurry device is with oil drilling solid control system supporting the use of a device, it can meet the 1500 meters to 6000 meters the deterioration of the drilling fluid and drilling solid control system configuration, JBQ series slurry unit is composed of a sand pump and a jetting mixing funnel connected with manifold valve installed on a base of safe and reliable performance, easy to move.

YZ Submersible slurry pump in Oil & Gas drilling

Brief Introduction

YZ Submersible slurry pump is with structure of vertical single stage and single suction system overhung centrifugal pump. It is made of abrasion-resistant alloy, It can convey medium with high concentration particle.

There is no bearing and Gland Seal between impeller and pump body, so the slurry pump is maintenance-free and high temperature resistance, the slurry pump is the ideal centrifugal pump for Feeding Shale Shaker from Mud Pit for HDD Mud Recycling.

Pump’s drive type: The slurry pump is connected through the flexible coupling and the electric motor, the pump direction of rotation is clockwise from the prime move.

YZ Submersible slurry pump structure

YZ Slurry  Pump is the cantilever pump structure of single stage and single suction, with the bearing housing, supporting, intermediate pipe connecting the  pump hydraulic components, the water is discharged out from the drain pipe parts, pump impeller is for semi-shrouded with the agitating vane on the vane extended, the main characteristic of this pump is the underwater pump shaft parts have enough rigidity, the impeller and pump shell have no bearings, no shaft seal, which can transport the greater medium of solid particles.

The length of inserting the water by slurry pump is between 800 and 2000; the suction pipe can be matched in case of need. The shaft seal runs into the underwater pump without setting up the shaft seal, drive should be installed the vertical motor on the supporting seat connecting with coupling and pump.

Buy submersible slurry pump from China manufacturer, OGEM Solids Control system submersible slurry pump. OGEM submersible slurry pump can be used in environmental protective, civil construction, power plant, oil refinery, mineral, cement factory, etc. industry.

It can pump various fluid with corrosiveness and particles, such as sludge, oil dregs, etc. Mud tank submersible slurry pump.

Mud Tank for drilling fluid solids control

The introduction of Mud Tank

Mud tank is an important part in the solid control system.It is a container, typically made of square steel tube and steel plate, to store drilling fluid on a drilling rig. Mud tanks play an important role in solids control system. It is the base of solids control equipments, and also the carrier of drilling fluids.

Acoording to tank base shape,there are sqare and cylinder tanks.Tanks main body are welded together with steel plate and steel pipe,rails top and walk way is made of steel grid and antiskid plate.Guard rail material is square pipe,rail are foldable type.Stairs are made of antiskid plate.Two sides rail have pins for steady and safe walk.Mud tanks in whole mud system will have special device to clean mud tank and equipments.For oil drilling mud system,we will provide standard sand/rain prevention canopy also heating pipeline in the tank.

Oilfield Vacuum Degasser in Solids Control

Oilfield Vacuum Degasser for Drilling Fluids Solids Control

Vacuum degasser actually is the 2nd purification equipment for oilfield drilling fluid.

It is used to remove little invaded gas in drilling mud. It will be set between shale shaker and mud cleaner/desander.

?????

Oilfield degassers

In oilfield drilling fluid system, there are 2 types degasser. One is poor boy degasser separate large quantity invaded gas, the other is the vacuum degasser, and we also call it gas buster.

Degasser in oilfield, main function is getting rid of invaded harmful or poisonous gas. To?prevent blowout?keep oilfield job site safe.

Vacuum degasser working principle

Vacuum degasser is vertical type degasser. It consists of vessel, base, vacuum pump, gear box, internal blade.

  • ?Basic principle is degasser adopts water circle vacuum pump. Based on vacuum gas or negative pressure the gas buster will remove harmful air rapidly. It is very necessary device in oil and gas drilling, explore well, and unbalance drilling. Adaptable for various well drilling fluid purification systems.
  • Furthermore, vacuum degasser also can filter some sundries out. This degasser has optimal structure and prime configuration, this help degasser reliable and efficient

Vacuum degasser for drilling fluids solids control

1. Vacuum Degasser is also called mud/Gas separator. Mud/gas separators (Degasser) is?the first units of solids?arranged to treat drilling mud. As such, they process all of the drilling mud from the flow line before the mud reaches the primary?shale shakers. The units have no moving parts and rely on the density difference between the gas and the mud for removal. The process is simple, yet very effective for well?drilling fluids processing system.

2. Vaccum Degasser?is used to remove the small entrained gas bubbles left in the mud by the mud/gas separator. These units are positioned downstream from mud/gas separators, gumbo removal equipments (if utilized),?shale shakers?and mud conditioners (if utilized), while?hydrocyclone desander and?Decanting centrifuges?follow in the arrangement.
