Ultra-high-density drilling kua yog qhov tseem ceeb rau kev ua tiavntawmdrilling thiab ua tiav ntawm ultra-dav reservoirs.
Qingdao Millennium Energy Co., Ltd. koom tes nrogTuam Tshoj University of Petroleum (EastChina) kev tshuaj xyuas thiab tshuaj xyuas kev tshawb fawb tus neeg saib xyuas qhov hnyav hauv qhov kub thiab txias siab, tsim ultra-high-density drilling kua system（2 35-2.65 g/cm3).
Thaumkho ua ntej kev tshuaj ntsuam pom uaszoo tib yambarite thiab hematite tsis yog qhov hnyav tshaj plawstus neeg sawv cev, vim lawv tended pawg nyob rau hauv high-density mob,Txawm tias qhov ceev ntawm 2.0 g / cm3, emulsion-breaking voltage (ES) ntawm lub systemyogTsis tshua muaj heev, piv txwv li, manganese tetroxide, ilmenite, thiab nto kho barite raws li qhov hnyav.tau ua tau zoo dua rusultnyob rau hauv ntau yam kev xeem ntawm drilling kua.Thaum lub purity ntawm manganese tetroxidetau ntau duatshaj 95 feem pua thiab purity ntawm ilmenitetau ntau duatshaj 85 feem pua, tus nqi ESyogntau tshaj 2000V,it qhia tau tias ruaj khov thiab siv tau zoo peev xwmuastuaj yeem siv los ua tus neeg saib xyuas qhov hnyav hauv ultra-high density oil-based drilling fluid systems.
Lub kaw lus tau raug xa mus rau hauv Middle East ntawm lub Missan Roj teb hauv Iraq,uasnruab nrab qhov tob tobyogntau tshaj 5,000m thiab qhov kub siab tshaj plawsyog180 degree
Tnws cov qhabnias qhia tau tias Lub siab ceev txwv ntawm barite drilling aggravation muaj peev xwm thaum tus txheej txheem yogib ncig2.65 g / cm33.Thusxav tauultrapure qib API barite thiab micropulverized bariterautswjtussiab ceev(Ntau dua qhov ntom thiab cov ntaub ntawv zoo tshaj plaws kom muaj qhov hnyav thiab tshem tawm),tseem ceebtus nqi yuav nce, thiabsib tw cov tshuab tsim khoom thiab muaj peev xwm.Due rau manganese tetroxide thiab ilmenite muaj zoo heev drilling kua rheological zog yuav yog ib qho kev xaiv rau barite..Siv no complexhnyavtus neeg sawv cev, lub ultra-high density drilling kua system muaj dav daim ntawv thov kev cia siab nyob rau hauv ntau hnyav geological tej yam kev mob.
