Solid Control & Drilling Waste Management Solution

E pisode I  Tarim Oilfield Drilling Waste  Treatment Current Situation Drilling cuttings is the main waste produced during drilling operation, including clay, heavy material, chemical treating agent, waste water, sump oil and drilling cuttings, and the kinds of polymer, heavy metal ion, salt, pitch and other modifying substance is harmful to environment. During drilling , each well generally produces about 800m³ drilling waste fluid, the drilling cuttings has no recovery value, only be piled up at wellsite mud pit, and the environment pollution is caused by hidden dangers. During recent years, Tarim oilfield oil and gas resources developed rapidly. And with the drilling wells quantity continuous increasing, the cumulative drilling waste has been placing a growing hazard to environment pollution. According to statistical data, in year 2009, the Tarim oilfield drilling waste reached to 130,000m³, including drilling cuttings about 50,000. While in year 2010, the drilling wast

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
