Drilling tiav tiav, teeb tsa xya Drilling Records nyob rau hauv ib kab

Tsis ntev los no, qhov thib ob qhib ntawm Bazhong 101HF zoo drilled los ntawm 70176 pab neeg ntawm Southwest ceg ntawm Shengli Petroleum Engineering Company tau ua tiav tiav. Cov dej drilling rau qhov qhib thib ob tau ua tiav. Cov duab txhua hnub ntawm qhov qhib thib ob ntawm Lianchuang Yuanba thaiv yog 502 meters, thiab ib qho kev mus ncig ua si yog 2,562 meters. meters, qhov siab tshaj plaws thiab nruab nrab ntawm cov tshuab drilling ceev yog 14.28 meters / teev thiab 12.91 meters / teev raws li, lub voj voog drilling yog 20.5 hnub, qhov drilling tau ua tiav hauv 2 mus ncig, thiab qhov tob tshaj plaws ua tiav drilling qhov tob ntawm qhov thib ob drilling yog 4, { {14}} meters. 7 cov ntaub ntawv tshiab rau qhov thib ob drilling hauv qhov thaiv.

Zoo Bazhong 101HF nyob rau hauv Tongjiang-tawm oblique Bazhong-sab qaum teb fault fold cheeb tsam nyob rau hauv lub low-gentle fold siv ntawm sab qaum teb Sichuan. Nws yog qhov kev ntsuam xyuas tseem ceeb uas tau siv los ntawm Sinopec Tshawb Fawb Chaw. Qhov tsim qhov tob tob yog 5,370 meters, thiab qhov qhib qhov thib ob yog 3,400 meters ntev. Nws siv 311.2 Thaum lub sij hawm tsim kho ntawm millimeter laum me ntsis, tsib txheej ntawm formations nrog sib txawv siab coefficients tau drilled hauv Jianmenguan Formation, Penglaizhen Formation, Upper Shaximiao Formation, Lower Shaximiao Formation, thiab Lianggaoshan Formation. Muaj ntau cov khaubncaws sab nraud povtseg, thiab kev sib tsoo ntawm qhov sib tsoo tau tshwm sim hauv cov qhov dej uas nyob ib sab. Risk ntawm huab cua to thiab tawg to.

Cov qhov dej uas nyob ib sab hauv Shaximiao thiab Lianggaoshan Formations feem ntau muaj kev nkag mus thiab cov roj nkag, ua rau kev tsim kho nyuaj. Raws li qhov xwm txheej no, thaum lub sijhawm tsim kho, pab pawg tau tsom mus rau kev ruaj ntseg ntawm phab ntsa zoo yog qhov tseem ceeb, xaiv qhov tsim nyog drilling kua qhov rais raws li qhov tseeb drilling, thiab raws li lub hauv paus ntsiab lus ntawm qhov ruaj khov siab thiab tsis muaj qhov to, xaiv qhov tsim nyog drilling kua ntom kom ntseeg tau tias cov phab ntsa zoo ruaj khov. Nyob rau tib lub sijhawm, kev saib xyuas cov av nkos tau ntxiv dag zog thaum lub sijhawm drilling. Kev xa rov qab ntawm lub vijtsam vibrating yog ib qho ntawm cov haujlwm tseem ceeb hauv txhua qhov kev hloov pauv, thiab tus neeg saib xyuas raug xa mus qhia nws txhua ib nrab teev ntawm walkie-talkie. Qhov no tsis tsuas yog ua kom muaj kev nyab xeeb hauv av xwb, tab sis kuj tseem txhim kho cov neeg kho tshuab zoo. Drilling ceev.
