Solid Control & Drilling Waste Management Solution

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 The liquid mud passes through the screens and is recirculated back to the mud tanks from which mud is withdrawn for pumping downhole.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 ...

S hale shakers typically consist of wire mesh  shaker screens  in various mesh sizes that shake or vibrate the drill cuttings which across and off the shaker screens as the drilling fluid or drilling mud flows through shaker screen s  and back into the drilling mud system.  There are mainly three types of shaker screens for different types of shale shakers, like PWP screen, PMD screen, and hook strip screen. PMD screens are Derrick ’ s patented products for Derrick 2000 series and Derrick 500 series shale shakers . While PWP and hook strip screens are widely used for world famous shale shakers like brand M-I SWACO, Derrick, Brandt and KOSUN. Hook strip s creen s  is a  common kind of s hale s haker s   s creen, which can be widely used in different conditions in drilling operation. This screen is constructed with two  or three layers of stainless steel wire cloths bonded to a steel...

Linear motion shale shaker  is  the  first stage  solids control equipment in drilling fluid   processing system, well  known as solids treating  equipment in solids control system . Linear motion shale shaker  decides the performance of the whole solids control system . Linear motion shale shaker  for solids control system   remove s  dril l  cuttings from drilling fluid during   mud circulat ion  and drilling.  Controlling the solids in drilling fluid is important to control  drilling  cost and protect environment. Linear m otion s hale s haker s typically consist of wire mesh shaker screens in  various mesh sizes that shake or vibrate the drill cuttings  which across and off the screens as the drilling fluid or drilling mud flows through shaker screen  and back into the drilling mud  system. This separates the solid drill cuttings from the fluid so that it can be recircu...

Drilling mud is employed to regulate subsurface pressures, lubricate the drilling bit, stabilize the well bore, and carry the drill solid cuttings to the surface, among alternative functions. Drill mud is pumped-up from the surface through the hollow drill string, exits through nozzles within the drilling bit, and returns to the surface through the ring-shaped   area between the drill string and also the walls of the outlet. As the drilling bit grinds rocks into drill cuttings, these drill cuttings become entrained within the mud flow and area unitcarried to the surface. so as to come the mud to the recirculating mud system and to create the drill solids easier to handle, the drill solids  should be separated from the mud. the primary step in separating the drill cuttings from the mud involves current the mixt...

Drill cuttings disposal is a hot topic these years with global attention to environmental protection, especially in O il & gas industry. D rill cuttings  disposal 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 cuttings are 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 cuttings are commonly examined to make a record (a  well log ) of the subsurface materials penetrated at various depths. In the oil industry, this is often called a  mud log .   One drilling method that does not produce drill cuttings is  core drilling , which instead produces solid cylinders of rock or soil.   In cable-tool ...
