Khoom Taw Qhia
Segmented fracturing ntawm kab rov tav zoo yog cov txheej txheem tseem ceeb ntawm shale gas reservoir kev loj hlob. Txoj kev zoo nyob hauv tsev thiab txawv teb chaws yog segmented fracturing ntawm compound choj plug. Txhawm rau tsim kev nkag mus rau theem tom ntej, coiled tubing yuav tsum tau siv los laum thiab zom tag nrho cov choj txuas. Lub pob tawg tawg yuav tsum tiv taus qhov kub siab ntawm ze li ntawm 150 degree thiab qhov sib txawv ntawm qhov siab ntawm ntau tshaj 70 MPa, thiab qhov kev ntxhov siab me me heev thaum nws nias. Yog li ntawd, lub thermal stability tiv thaiv luv luv Circuit Court thiab mechanical zog ntawm lub pob tawg yog yuav tsum tau.
Lub tuam txhab uas twb muaj lawm soluble hlau fracturing npas, soluble polymer fracturing npas thiab lwm yam khoom. Tam sim no peb tuaj yeem muab cov neeg siv khoom nrog txoj kab uas hla ntawm 10mm mus rau 120mm fracturing pob khoom. Nyob rau tib lub sijhawm, txhawm rau ua kom tau raws li cov kev xav tau ntawm cov neeg siv khoom, peb tuaj yeem kho qhov kev txhim kho ntawm cov khoom sib tsoo pob nrog kev ua tau zoo raws li kev siv thiab qhov ntau thiab tsawg los ntawm cov neeg siv khoom.
