Solid Control & Drilling Waste Management Solution

Application D ecanter centrifuge is used in separating suspension of solid phase with 2～70% solid concentration, liquid viscosity ≤0.01PaS, particle diameter d≥2μm, in clarifying suspensions with little solids as well as amorphous material that brings difficulties for filtering cloth regeneration and suspensions which have a big change range in solid phase concentration. T he d ecanter centrifuge is also used in the solid-liquid separation  in the fields of oil & gas industry , chemical industry, food, pharmacy and environmental protection, carrying out dehydration of solid phase, liquid clarifying, liquid-liquid-solid separating, granularity grading and other separating processes. Structure DC series horizontal decanter centrifuge is driven by two motors. The main motor drives the drum and the outer casing of differential through belts while the auxiliary motor, after the differential shifting speed, drives the spiral propeller. This will make the drum and the s

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 drilling, the drill cuttings are periodically bailed o

  Drilling cuttings treating solutions will depend on the drilling mud characteristics. Oil-based mud is a mud  where the base fluid is a petroleum   product   such as diesel fuel , kerosene, fuel oil, selected crude oil or mineral oil. For OBM ’ s complexity, the drilling cuttings treating solutions will have more strict demands on  the processing  equipment. Oil-based mud are used for many reasons, including increased lubricity, enhanced shale inhibition, and greater cleaning abilities with less viscosity. Oil-based mud   also withstand greater heat without breaking down. The use of oil-based mud has special considerations, including cost, environmental considerations such as disposal of cuttings in an appropriate place, and the exploratory disadvantages of using oil-based mud, especially in wildcat wells. Using an oil-based mud interferes with the geochemical analysis of cuttings and cores and with the determination of  API gravity  because the base fluid cannot be distin

In  geotechnical engineering ,   drilling fluid is used to aid the drilling of  boreholes   into the earth , o ften used while drilling  oil  and  natural gas  wells and on exploration drilling rigs , and  also for much simpler boreholes  like   water wells . Liquid drilling fluid is often called drilling mud. The three main categories of drilling fluids are water-based mud (which can be dispersed and non-dispersed), non-aqueous mud, usually called oil-based mud, and gaseous drilling fluid, in which a wide range of  gases  can be used. The main functions of drilling fluids include :  providing  hydrostatic pressure  to prevent  formation fluids  from entering into the well bore, keeping the  drill bit  cool and clean during drilling, carrying out drill cuttings, and suspending the drill cuttings while drilling is paused and when the drilling assembly is brought in and out of the hole. The drilling fluid used for a particular job is selected to avoid formation damage  and to limi
