Choj xuab zeb drilling daig thiab kev kho mob xwm txheej

Choj xuab zeb daig kuj hu ua xuab zeb daig, nws qhov xwm txheej zoo ib yam li kev tawg, thiab nws qhov kev puas tsuaj phem dua li kev daig.

1. Qhov laj thawj ntawm kev tsim choj xuab zeb

(1) Nws yooj yim tshwm sim thaum drilling nrog dej huv hauv cov qauv mos;
(2) Lub plhaub ntawm qhov chaw me dhau, thiab cov stratum mos mos raug nthuav tawm ntau dhau;
(3) Ntxiv cov flocculant ntau dhau rau cov kua dej drilling;
(4) qhov ceev ntawm kev khawb av yog ceev, qhov kev hloov pauv ntawm cov kua dej tsis tuaj yeem ua raws li;
(5) Hloov cov kua dej qub hauv lub qhov dej, lossis hloov pauv qhov ua tau zoo ntawm cov kua dej drilling;

Qhov tshwm sim ntawm cov choj xuab zeb lo rau

(1) Tsis muaj kua dej drilling rov qab mus rau lub qhov dej thaum lub sijhawm drilling lossis cov kua dej drilling raug thim rov qab hauv tnws cov yeeb nkab laum;

(2) Qhov tsis kam ntawm cov cuab yeej drilling yog qhov tsis kam mos, thiab tsis muaj qhov tsis kam ruaj khov tam sim ntawd ptshuaj pleev;

(3) Yog tias lub choj xuab zebe tshwm sim thaum lub sijhawm drilling, cov kua dej ntawm lub annulus poob qis, thiab cov kua dej hauv qhov dej ntawm lub cuab yeej drilling poob qis sai;

(4) Tom qab lub cuab yeej drilling nkag mus rau hauv lub choj xuab zeb, ua ntej lub twj tso kua mis pib, qhov kev txav mus los thiab kev sib hloov yog dawb. Yog tias lub twj tso kua mis yuav tsum pib, lub twj tso kua mis siab yuav ncese, qhov hnyav uas raug ncua yuav poob, thiab cov kua dej drilling yuav tsis rov qab los yog rov qab me ntsis ntawm lub qhov dej;

(5) Thaum lub sijhawm drilling, xws li cov kua dej me me uas raug tshem tawm lossis cov xuab zeb tsis muaj peev xwm nqa tau, thaum lub twj tso kua mis ncig, lub cuab yeej drilling tig mus rau saum thiab nqis tsis muaj kev tiv thaiv, thaum lub twj tso kua mis nres, lub cuab yeej drilling tsis tuaj yeem nqa tau, tshwj xeeb tshaj yog tsis muaj cov kua dej drilling theem khov kho, qhov no tshwm sim ntau dua.

Kev tiv thaiv ntawm cov choj xuab zeb daig

(1) Nws yog qhov zoo tshaj plaws kom tsis txhob siv dej los khawb;

(2) Hauv qhov qhib qhov, lub sijhawm ntawm cov kua dej drilling so yuav tsum tsis txhob ntev dhau;

(3) Kev txhim kho ntawm drtsim cov kua dej;

(4) Thaum lub sijhawm drillingg, qhov tsim nyog ntawm lub twj tso kua mis yuav tsum tau xaiv raws li cov yam ntxwv tsim;

(5) Txhawm rau kom muaj kev ruaj khov ntawm cov kua dej drilling thiab kev ua tau zoo.

Kev kho mob ntawm tus choj xuab zeb uas daig

(1) Yog tias lub qhov drillinguid tsuas yog nkag mus rau hauv lub twj tso kua mis xwb, lub cuab yeej drilling tau daig, thiab nws tsis tuaj yeem txav mus los, nws yuav tsum tau xam qhov chaw ntawm daim npav taw tes, thiab lub sijhawm yuav tsum tau thim rov qab los ntawm qhov ze ntawm daim npav taw tes.

(2) Qhov chaw ntawm cov xuab zeb choj tsim yuav nyob rau sab saud lossis sab qis, tab sis nws qhov seem tsis ntev dhau, thiab nws tsis yooj yim sua kom faus tag nrho cov cuab yeej drilling. Yog tias cov xuab zeb choj nyob rau sab saud, txawm hais tias tsis muaj ntau cov cuab yeej laum nchuav tawm thawj zaug, nws tsis yooj yim sua kom siv lub tes tsho ntev milling kom tshem tawm cov xuab zeb choj, thiab tom qab ntawd cov cuab yeej laum yog nyob rau ntawm lub pob kom rov qab kho qhov kev ncig, thiab tom qab ntawdtej yam yooj yim dua ua. Yog tias lub choj xuab zeb nyob rau hauv qab, txoj kev ntawm kev blasting xoob backbuckle yuav tsum tau siv los nchuav cov cuab yeej laum tsis tau daig ib zaug, thiab cov cuab yeej laum hauv qab no tsuas yog tuaj yeem unstuck los ntawm milling backbuckle.

(3) Cov xuab zeb choj daig drilling feem ntau tshwm sim thaum lub sijhawm tripping, lub laum tsis nyob hauv qab ntawm lub qhov, yog li ntawd hauv cov txheej txheem milling, cov ntses yuav tog, hauv qhov no, nws yuav tsum tau immedNyob rau ntawm lub pob, lub cuab yeej drilling, nws muaj peev xwm tso daim npav hauv qhov kev ua ub no. Yog tias peb tuaj yeem ncig cov kua drilling, txhua yam teeb meem yuav raug daws.

(4) Yog tias txoj hlua laum muaj lub hauv paus, lub choj xuab zeb feem ntau nyob saum lub hauv paus kawg, yog li tom qab lub tshuab zeb casing mus rau lub hauv paus, nws tsis tas yuav tsum tau reamer los zeb lub hauv paus, thiab lub thawv tuaj yeem raug co thiab tshem tawm.
