Pa 10:30 pa July 20, CNPC Shendi Chuanke 1 chitsime, chitsime chovuta kwambiri padziko lonse lapansi, chinayamba kubowola ku Sichuan Basin. Izi zisanachitike, pa Meyi 30, chitsime cha CNPC Deepland Tako 1 chidakumbidwa mu Tarim Basin. Kumpoto ndi kumwera kumodzi, "nyenyezi ziwiri" zakuya kwakuya kwa mamita 10,000 zimawala, zomwe zimapereka maziko ofunikira komanso chithandizo cham'tsogolo cha dziko langa kafukufuku wa sayansi ndi chitukuko cha mafuta ndi gasi.
Mapangidwe a geological ndi ovuta ndipo zizindikiro 7 zovuta zimakhala zoyamba padziko lapansi.
Nthawi zambiri, makampaniwo amatanthauzira zitsime zozama za 4,500 mpaka 6,000 metres ngati zitsime zakuya, zitsime zozama za 6,000 mpaka 9,000 metres ngati zitsime zozama kwambiri, komanso zitsime zozama kwambiri kuposa 9,000 metres. zitsime. Kubowola kozama kwambiri ndi gawo lomwe lili ndi zovuta zaukadaulo kwambiri komanso zovuta zazikulu paukadaulo wamafuta ndi gasi.
Chabwino Shendi Chuanke 1, yomwe ili kumpoto chakumadzulo kwa Sichuan Basin, yazunguliridwa ndi mapiri ndi mapiri, okhala ndi mtunda wa mamita 717 ndi chitsime chozama cha mamita 10,520. Pali ma seti angapo amadzi am'madzi apamwamba kwambiri omwe amasanjidwa mozama kwambiri m'derali, ndipo mikhalidwe yodziunjikira ndiyopambana. Akachita bwino, akuyembekezeka kupeza malo atsopano osungiramo gasi wachilengedwe wozama kwambiri.
Malinga ndi a Zhao Luzi, katswiri wazamisiri wamakampani a PetroChina Southwest Oil and Gas Field Company, Sichuan achita bwino kwambiri pakufufuza ku Penglai Sinian-Lower Paleozoic pamtunda wozama kwambiri wa 6,000 mpaka 8,000 metres. Mkhalidwe wa gulu losungiramo mpweya. Pali zitsime ziwiri zokha zobowoleredwa mozama mamita 8,000, "Wutan 1 Well" ndi "Pengshen 6 Well". Digiri yowunikira ndiyotsika kwambiri ndipo kuthekera kofufuza ndikwambiri.
Mlingo wa kumasulira kwa zida zodziyimira pawokha zofufuzira ndi chitukuko ndizoposa 90%.
Popanda diamondi, tingachite bwanji ntchito zadothi. Panthawi yoboola chitsime chakuya mamita 10,000, padzakhala zovuta zambiri, zazikulu zomwe zimakhala kutentha kwambiri.
"Paziwonetsero zobwerezabwereza, aliyense anali ndi nkhawa zambiri. Kutha kwa mamita 9,000 sikutanthauza kutha kwa mamita 10,000." Yang Yu adanena kuti kuya kwa chitsime kukadutsa makilomita asanu ndi awiri kapena asanu ndi atatu, vuto silikuwonjezeka motsatira mita iliyonse pansi. ndi kukula kwa geometric. Pansi pa mamita 10,000, kutentha kwa madigiri 224 Celsius kungapangitse zida zobowola zitsulo kukhala zofewa ngati Zakudyazi, ndipo malo othamanga kwambiri a 138 MPa ali ngati kudumphira m'nyanja yakuya mamita 13,800, kupitirira kwambiri kuthamanga kwa madzi a m'nyanja. Mtsinje wa Mariana, nyanja yakuya kwambiri padziko lapansi.
Kubowola kwa mita 10,000 ndi "mwala wakuthwa". Sikuti kuyesa "kufufuza chuma" mozama, ndizosamvetsetseka monga "kumasula bokosi", komanso kudzipatula, komwe kumafunika kutsitsimula malire nthawi zonse. Kukhazikitsidwa kwa chitsime cha Shendi Chuanke 1 kudzaululanso zinsinsi zachisinthiko pansi pa Sinian strata, kufufuza zakuya zamafuta ndi gasi zozama mamita 10,000, kupanga zatsopano ndikupanga chiphunzitso chambiri chakuzama kwamafuta ndi gasi, ndikulimbikitsa dziko langa. mafuta ndi gasi engineering pachimake ukadaulo ndi zida Kutha kupita sitepe imodzi patsogolo.
