Cov ntsiab lus
OBF-LUBE WB yog ib puag ncig tus phooj ywg dej-raws li roj nplua nyeem raws li polymeric cawv, uas muaj shale inhibition zoo, lubricity, kub stability thiab tiv thaiv kev ua qias tuaj.Nws yog non-toxic, yooj yim biodegradable thiab tsis tshua muaj kev puas tsuaj rau cov roj tsim, thiab yog dav siv nyob rau hauv oilfield drilling ua hauj lwm nrog cov nyhuv zoo.
Nta
Txhim kho cov rheology ntawm cov kua dej drilling thiab ua kom cov theem muaj peev xwm txwv los ntawm 10 mus rau 20%.
Kev txhim kho ntawm cov organic kho tus neeg saib xyuas cov cua sov stabilizer, txhim kho qhov kub thiab txias ntawm cov neeg ua haujlwm kho los ntawm 20 ~ 30 ℃.
Muaj peev xwm tiv thaiv kev tawg, tsis tu ncua txoj kab uas hla, qhov nruab nrab borehole loj npaum li cas ≤ 5%.
Borehole av nkos ncuav mog qab zib nrog cov khoom zoo ib yam li roj-raws li drilling kua av nkos ncuav mog qab zib, nrog zoo lubrication.
Txhim kho filtrate viscosity, molecular colloid thaiv thiab txo cov roj-dej interfacial nro los tiv thaiv lub reservoir.
Tiv thaiv cov av nkos ntawm cov laum me ntsis, txo cov teeb meem nyuaj downhole thiab txhim kho cov neeg kho tshuab drilling ceev.
LC50> 30000mg / L, tiv thaiv ib puag ncig.
