Kev Tsim Kho Technology ntawm Rov Qab Circulation Drilling Rig
Qhov rov qab ncig drilling rig tsim los ntawm Handan Pob Zeb Drilling Engineering Machinery, cov txheej txheem crushing ntawm qhov cuam tshuam rov qab ncig crushing pob zeb nkag txheej txheem yog siv cov kev cuam tshuam laum me ntsis los cuam tshuam lub pob zeb ntawm ntau zaus kom tawg lub pob zeb, thiab tom qab ntawd siv qhov thim rov qab. Txoj kev ncig slag tawm txoj hauv kev kom lub sijhawm tsoo pob zeb. Cuttings yog tawm ntawm lub qhov tam sim ntawd. Qhov cuam tshuam laum me ntsis yog sib npaug sib txuas los ntawm ob txoj hlua hlau, uas yooj yim heev rau kev drilling nce thiab nqis, thiab ua rau lub sijhawm ua haujlwm luv.
Yog li ntawd, lub percussion rov qab ncig laum ntsis yog lub ntsiab cuab tam rau percussion drilling, thiab lub rationality ntawm nws cov qauv ncaj qha cuam tshuam rau lub drilling efficiency thiab zoo. Nyob rau hauv cov txheej txheem percussion drilling, tus yuam sij yog seb qhov cuam tshuam thiab slag nqus qhov sib tw, uas tseem yog qhov tseem ceeb tshaj plaws thiab cov xwm txheej tseem ceeb los xyuas kom meej qhov ruaj khov ntawm lub qhov phab ntsa thiab ib txwm drilling. Thaum lub sij hawm drilling txheej txheem, kev ua hauj lwm ntawm slag suction yuav tsum tau txiav txim siab raws li lub drilling tsim thiab tej yam kev mob, thiab ntau tshaj slag yuav tsum tsis txhob sucked kom tsis txhob muaj qhov instability ntawm lub qhov phab ntsa thiab lub cev qhuav dej ntawm lub qhov. Ib qho kev sib tsoo drilling tshwm sim. Tsis tas li ntawd, thaum lub sij hawm muaj kev cuam tshuam cov txheej txheem, kev hnav ntawm cov hlau hlau hlua thiab qhov hloov tau yooj yim ntawm lub kauj tsheb thiab kev ruaj khov ntawm kev sib txuas yuav tsum tau kuaj xyuas ntau zaus kom tsis txhob hnav cov hlua hlau los ntawm kev hnav los yog twist vim qhov tsis zoo ntawm lub kauj, ua rau muaj kev cuam tshuam ntawm cov txheej txheem. kev sib tsoo drilling.
Raws li geological tej yam kev mob, qhov tso zis ntawm lub laum me ntsis thiab cov khoom abrasive yuav tsum tau xyuas ntau zaus thaum nqa lub laum. Feem ntau, lub laum me ntsis yuav tsum tau kuaj xyuas tsawg kawg ib zaug rau ib qho kev hloov me me hauv qhov dav dav stratum. Tus naj npawb ntawm laum me ntsis nqa yuav tsum tau nce nyob rau hauv complex strata. Hauv qab thiab cov zis ntawm lub laum me ntsis feem ntau hnav hauv cov xuab zeb, pebbles thiab bedrock. Nws yog qhov hnyav, yog li nws yuav tsum tau kho lub sijhawm, uas ua rau kom lub sijhawm tso rau kev kho lub laum me ntsis, txo lub sijhawm ua haujlwm zoo ntawm drilling, thiab txo lub sijhawm pabcuam rau kev kho lub laum me ntsis. Tsis tas li ntawd, thaum nqa lub laum me ntsis, yuav tsum ceev faj, tshwj xeeb tshaj yog nyob rau hauv qhov nkag mus rau hauv qab ntawm lub casing thiab maj mam nqa lub laum me ntsis kom tiv thaiv kev sib tsoo nrog lub qhov casing kom tsis txhob poob rau hauv qab ntawm lub casing los yog misalignment los yog deformation ntawm lub casing. .
