Solid Control & Drilling Waste Management Solution

S olids control equipment s hale shakers typically co mposed  of wire mesh  shaker screens  in  kinds of  mesh sizes that vibrate the drill waste  across and off the shaker screens as the drilling fluid or drilling mud flows through shaker screen s   in the solids control system and back into mud system.  Usually there are  three types of shaker screens for different shale shakers, including  PWP screen, PMD screen, and hook strip screen. PMD scree is Derrick ’ s patented products for Derrick 2000 series and Derrick 500 series shale shakers. While hook strip screens  and PWP screens are w idespread a pplication to  world famous shale shakers like brand Derrick, Brandt , M-I SWACO, and KOSUN. The steel frame shaker screen  is the most commonly shaker screens composed of steel frame and two or three  layers SS304  cloth.   Frame shaker screen  is commonly used ...

When  bit grinds downward through the rock layers, it generates giant amounts of ground-up rock referred to as drilling cuttings . The standard method of drilling oil and gas wells uses a rotary bit that's greased by drilling fluids or drilling d  mud. This section discusses many different drilling practices that end in a lower volume of drilling cuttings  generated. Usually wells aren't trained from high to bottom at identical diameter, however rather in an exceedingly series of increasingly smaller-diameter intervals. Oil and gas wells square measure created with multiple layers of pipe referred to as casing. the highest interval is trained beginning at the surface and has the biggest diameter hole with great quantity of drilling cuttings  . Once an acceptable depth has been reached, the outlet is lined with casing that's slightly smaller than the diameter of the outlet, and cement is tense into the house between the wall of the trained hole and therefor...

Drilling mud recovery Most OBM drilling mud is disposed once drilling work finished. In contrast, much oil-based drilling mud and synthetic-based drilling mud is recycled possible. Sometimes the physical and chemical properties of the used drilling mud have degraded somewhat, and the drilling mud must be processed to rejuvenate the necessary properties. In other cases, drilling mud have been degraded sufficiently that it cannot economically be reused as new drilling mud. There are many relatively simple processes that can be used on drilling rigs to capture clean drilling mud that would otherwise be discarded and return for reuse. Like pipe wipers, mud buckets, and vacuuming of spills on the rig floor. Recovery of mud during tank cleaning may also allow the mud to be reused. Solids control equipment, like centrifuges, can be used to remove solids from the recirculating mud stream. Some new dri...

Drilling waste management is a hot topic these years with global attention to environmental protection, especially in O il & gas industry. Drilling waste management  into environment without any treatment is strictly forbidden. So before disposal, a series methods must be introduced to treat the cuttings and make it reach to disposal standard. Drill ing   waste   is  produced as the rock is broken by the drill bit advancing through the rock or soil; the cuttings are usually carried to the surface by  drilling fluid  circulating up from the drill bit   by  rotary ,  percussion , or auger methods. The drill ing waste  is commonly examined to make a record (a  well log ) of the subsurface materials penetrated at various depths. In the oil and gas industry, this is often called a  mud log .   One drilling method that does not produce drill ing   waste  is  core drilling , which instead produces s...

Submersible slurry pump is used in drilling fluid solids control system to pump the thick liquid, thick oil, oil residue, dirty fluid, mud and fluid which contains clay sand slag and corrosive fluid. Submersible slurry pump produced by KOSUN Machinery has the advantages of high efficiency, maintenance free, high temperature resistance, long service life and so on. KOSUN LSP Series Submersible slurry pump is mainly used in environmental protection, new type building materials, coal washing, municipal works, thermal power generation, coal gas coking planet, refinery, mining, paper making, cement plant, food products factory and other fields to pump thick oil, oil residue, dirty oil, mud, mortar, running sand and other liquids. Or used to pump liquid containing silt materials and corrosive liquids in chemical and medicine industry. Submersible slurry pump is with structure of vertical single stage and single suction overhung centrifugal...

M ono screw pump , also called  sewage pump  or  progressive cavity pump ,  belongs to the rotor type positive displacement pump .   M ono screw pump  is depend ing  on the screw meshing with liner on the discharge and suction cavity to conveying liquid volume change.   It is a kind of method of pressurized screw pump, a main working parts by bushing has a double helix cavity (stator) and the stator cavity and its meshing singlehead screw screw (rotor).   When the input shaft through the universal joint drive making planets revolving around the center of the stator, rotor stator, rotor, vice is continuous mesh form sealed cavity, the seal chamber volume invariably uniform axial movement, the medium from the suction end of deputy to the stator, rotor pressure side, the suction medium sealed cavity through the stator without stirring and destruction. M ono screw pump  is an ideal pump used to feed drilling fluids to ...

Shale shaker is the 1 st  stage separation equipment for oilfield solids control  system . It adopts  vibrating motor to generate vibrating force . The vibrating force  drives the drilling fluid with cuttings   pass  through the   shale shaker . When the drilling fluid  goes through the   shale shaker screen , clean mud will be filter ed and goes  into mud tank. No n- allowable bigger solids will pass the screen surface and be discharged  to cuttings pot . There are mainly two types of shale shaker applied in solids control system for drilling cuttings separation. A.  Balanced elliptical motion shale shaker . It is not recommended for oil and gas drilling since the flow capacity is big. If the mud flow is not equal, the motion of shaker will be changed. And performance will not be good. Mostly, professional users prefer linear motion for wide application. B.   Linear motion shale shaker . This is the m...

Drilling mud is used to control subsurface pressures, lubricate the drill bit, stabilize the well bore, and carry the cuttings to the surface, among other functions. Mud is pumped from the surface through the hollow drill string, exits through nozzles in the drill bit, and returns to the surface through the annular space between the drill string and the walls of the hole.   As the drill bit grinds rocks into drill cuttings , these cuttings become entrained in the mud flow and are carried to the surface. In order to return the mud to the recirculating mud system and to make the solids easier to handle, the solids must be separated from the mud. The first step in separating the cuttings from the mud involves circulating the mixture of mud and cuttings over vibrating screens called shale shakers. The liquid mud passes through the screens and is recirculated back to the mud tanks from which mud is withdrawn for pumping downhole. The drill cuttings remain on top of the ...
