Lub Cenozoic Strata nyob rau hauv subei phiab yog tsim tau tag nrho thiab txhua txheej muaj cov cem zoo, nrog lub siab zoo tab sis tsis tshua muaj peev xwm muaj peev xwm; cov av nkos shales nyob rau hauv lub dainan tsim thiab kev lom zem yog qhov ua rau dej nqus thiab o, ua rau muaj teeb meem xws li spalling thiab collapse.
Tus Tswv Cuab Thib Ob yog lub ntsiab hydrocarbon los txheej thiab cov av vov tsev yog qhov ruaj khov rau sab hnubte {1} Daws cov teeb meem no, raws li cov tswvyim ntawm geology - kev sib xyaw ua ke, kev tshawb fawb engineering, kev tshawb fawb thiab daim ntawv thov tau ua tiav hauv ntau yam {}}
Ua ntej, nyob rau hauv cov nqe lus ntawm cov qauv zoo thiab kev ua kom zoo ntawm cov qauv ntawm ge{ muab kaw cia rau ib qho kev tsim tshwj xeeb, zam cov teeb meem xws li kev tsim kho Sanduo uas muaj kev txhim kho kom zoo dua qub Muaj peev xwm .
Thib ob, txheej txheej ceev - nce thev naus laus zis ntawm cov khoom siv ncaj qha, kev sib xyaw ua ke zoo li xaiv cov tshuab siv hluav taws xob nrawm hauv Loj - qhov loj me ntu; Hauv cov ncaj - Cov seem zoo thiab seem taw qhia nrog ib qho chaw qhib thib ob, kev sib xyaw ua ke tau xaiv los ua kom muaj kev nkag mus rau hauv lub qhov rais; Nyob rau hauv kab rov tav zoo, kev sib xyaw ua ke xws li kev siv PDC zoo heev thiab nce qhov drilling sib ntsib ntawm cov siab - cov khoom ua tau zoo.
Thib peb, Qhov Txhaum - Sib Koom Tes Tswj thev naus laus zis, nkag mus rau qhov kev tswj hwm ua ke, kom pom kev sib xyaw ua ke, xyuas kom meej meej lub kaum, kom paub meej tias qhov kev cim nrawm thiab ua tau zoo thiab ua tau zoo ntawm kev tsim, khiav ceev ceev los ntawm qhov txhaum, thiab xyuas kom cov reservoir ntsib tus nqi .
Plaub, Kev Txhim Kho - Parameter Drilling Technology {{1} Kev hloov pauv ntawm cov khoom siv Subiin, kev hloov kho cov khoom siv siab heev, thiab txhim kho cov khoom siv hydraulic thiab pob zeb - tawg efficiencies .
Qhov thib tsib, kev sib txhuam - txo thiab lub zog ua kom zoo nkauj, txhim kho kev sib txhuam kev tsim kho, txhim kho cov kev ua kom zoo nkauj, txhim kho txoj kev tsim kho kev ua haujlwm zoo, thiab tsis txhob muaj kev poob siab - Cov khoom lag luam shatic dej zoo nkauj thiab cov xwm txheej xws li sidetracking tom qab sau lub siab .
Thib rau, lub zog - sealing dawb - roj - raws li Drilling cov khoom muaj peev xwm, pab txhawb cov ntu kab rov tav thiab cov khoom ruaj khov, thiab cov tib lub sij hawm txo cov nqi. pa xya, kev tswj hwm kev siv hluav taws xob kom huv si thiab kev tswj hwm kev nyab xeeb Txhawm rau paug cov roj - raws li cov tshuab ntsuas dej tau ua tiav - huathe {} {} hf, ua tiav zoo tshaj plaws. tus Qhov nruab nrab drilling ntawm cov ntawv thov siv tau ua kom luv los ntawm 57 {31%, thiab nruab nrab tshuab nqus hluav taws xob tau nce los ntawm 129 {{}} 07%. Piv txwv li, hauv Huaaye {{{4 - 1 hf zoo, cov neeg siv tshuab drilling tau nce los ntawm kev ceev ceev - ua thev naus laus zis.
Thaum drilling los ntawm kev txhaum, nws tau muaj kev nyab xeeb dhau los thiab ua kom zoo dua qub txhim kho qhov hnyav - ntawm kev hloov kho cov tshuab ua kom zoo dua qub
Hauv kev tshawb pom, kev tshawb fawb thiab kev thov ntawm cov kev ua haujlwm tseem ceeb no tau ua kom muaj zog thiab loj - ntsuas kev txhim kho cov roj subtei hauv subei .
Txawm li cas los xij, nws tseem tsim nyog los ua kom zoo dua cov sealing thiab siab - tswj cov kev tshawb fawb lub zog, txhawb nqa cov khoom siv drilling kom tau raws li kev loj hlob qib siab {}}
