Kev tswj cov khoom khov yog ib qho txheej txheem siv rau hauv cov tshuab drilling uas siv cov kua drilling. Nws cuam tshuam nrog kev sib cais "cuttings" (cov khoom siv drilling) ntawm cov kua, cia nws rov ua dua lossis tso tawm rau ib puag ncig.[1]
Cov txheej txheem tswj cov khoom khov kho siv rau 1000-9000 meters 'roj thiab roj av qhov dej drilling txheej txheem thiab muaj 3 txog 7 lub tank sib xyaw ua ke. Hauv qab ntawm lub tank purification siv lub hauv paus tshiab cone, thaum ntug siv cov av nkos sib tov uas tsis yooj yim rau teeb xuab zeb. Yuav kom ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm drilling, tag nrho cov circulating system tuaj yeem sib cais thiab txuas ntawm lub tank thiab lub tank lossis ntawm lub tsev rau khoom thiab lub tsev rau khoom, ntawm lawv lub valve hauv qab ntawm lub manifold suction qhib tau yooj yim thiab kaw ruaj khov tom qab nws kaw. Tag nrho cov circulating system yog teeb tsa nrog qib 5 purification khoom siv, shale shaker hauv cov khoom siv corollary, desand thiab desilt cleaner, nqus degasser thiab agitator thiab lwm yam. Kev siv cov roj drilling av nkos purification system tshiab txo cov pa phem av nkos nrog lub luag haujlwm pom tseeb ntawm kev tiv thaiv ib puag ncig.
Lub tshuab tswj cov khoom khov siv los cais thiab tswj cov khib nyiab thiab cov xuab zeb thiab lwm yam khoom me me hauv cov kua dej drilling, tswj kev ua haujlwm ntawm cov kua dej drilling thiab khaws cov kua dej drilling. Nws muaj cov khoom siv sib tov hnyav, cov khoom siv infusion thiab cov khoom siv tshuaj lom neeg, uas siv los txhim kho kev ua haujlwm ntawm cov kua dej drilling kom ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm drilling.
Cov khoom siv tswj cov khoom khov uas tsim los ntawmHERIS, dais cov yam ntxwv ntawm kev ua tau zoo heev, ua haujlwm txhim khu kev qha, yooj yim txav mus los thiab kev lag luam pheej yig. Kev ua tau zoo thiab kev tsim khoom zoo ntawm cov txheej txheem tiav tau mus txog qib siab ntawm tib hom khoom hauv tsev.
