Ua rau thiab cov kev daws teeb meem ntawm drilling sticking

Sticking, tseem hu ua qhov sib txawv siab ua kom sib txawv, yog qhov kev sib tsoo ntau tshaj plaws hauv cov txheej txheem drilling, suav txog ntau dua 60% ntawm kev ua tsis tiav.

Yog vim li cas rau sticking:

(1) Txoj hlua drilling muaj lub sijhawm zoo li qub hauv qhov dej;

(2) Lub siab sib txawv hauv qhov dej yog qhov loj;

(3) Kev ua haujlwm tsis zoo ntawm cov dej drilling thiab qhov tsis zoo ntawm cov av nkos ua rau muaj kev sib txhuam coefficient loj;

(4) Tsis zoo borehole zoo.

Cov yam ntxwv ntawm cov laum sticking:

(1) Kev sib txuas yog nyob rau hauv lub xeev zoo li qub ntawm txoj hlua laum tuaj yeem tshwm sim, raws li lub sijhawm zoo li qub yuav tshwm sim daig, muaj feem cuam tshuam nrog cov dej drilling, kev ua haujlwm, cov qauv drilling, qhov zoo, tab sis yuav tsum muaj cov txheej txheem zoo li qub.

(2) Tom qab siv lub laum, txoj hauj lwm ntawm qhov taw tes yuav tsis yog lub laum me ntsis, tab sis lub laum dab tshos lossis laum yeeb nkab.

(3) Ua ntej thiab tom qab ua kom tiav, cov dej ntws hauv qhov drilling yog qhov qub, qhov kev xa tawm thiab xa tawm yog sib npaug, thiab lub twj tso kua mis siab tsis hloov.

(4) Tom qab ua raws li qhov kev xyaum ua haujlwm, yog tias qhov kev ua si tsis tau raws sijhawm, qhov taw tes daig yuav txav mus los, lossis txawm txav ncaj nraim ze ntawm cov khau khau.

Tiv thaiv kom txhob lo lo ntxhuav:

Cov kev cai dav dav, lub sijhawm drilling hlua yuav tsum tsis pub tshaj 3 feeb. Qhov kev ncua deb ntawm txhua qhov xyaum tsis pub tsawg tshaj 2m, thiab kev sib hloov tsis pub tsawg tshaj 10 cycles. Tom qab qhov kev ua si yuav tsum tau rov qab mus rau qhov qub raug ncua qhov hnyav.

Yog tias lub laum me ntsis nyob rau hauv qab ntawm lub qhov thiab tsis tuaj yeem txav thiab tig, nws yuav tsum tau nias 1/2-2/3 ntawm qhov hnyav ntawm cov cuab yeej laum ntawm lub laum me ntsis txhawm rau khoov txoj hlua qis, txo qhov chaw sib cuag ntawm txoj hlua laum thiab phab ntsa av nkos ncuav mog qab zib, thiab txo tag nrho cov adhesion.

Thaum lub sij hawm ib txwm drilling, xws li tsis ua hauj lwm ntawm tus kais dej los yog hose, lub kelly yeeb nkab yuav tsum tsis txhob zaum ntawm lub taub hau rau tu. Yog hais tias daig drilling tshwm sim, nws yuav poob qhov muaj peev xwm ntawm nias thiab tig txoj hlua laum.

Kev kho ntawm cov laum sticking:

(1) Muaj zog ua haujlwm

Txoj kev nplaum ua ntau dua thiab hnyav dua nrog lub sijhawm txuas ntxiv. Yog li ntawd, nyob rau hauv thawj theem ntawm kev tshawb pom ntawm stick, lub siab tshaj plaws quab yuam yuav tsum tau nqa tawm nyob rau hauv lub ruaj ntseg load ntawm cov khoom (tshwj xeeb tshaj yog lub derrick thiab ncua kev kawm ntawv system) thiab laum txoj hlua. Nws tsis dhau qhov kev txwv tsis pub muaj kev nyab xeeb ntawm qhov tsis muaj zog txuas, thiab qhov hnyav ntawm tag nrho cov hlua tho tuaj yeem raug nias rau ntawm qhov qis qis, thiab kev sib hloov tsim nyog kuj tuaj yeem nqa tawm, tab sis nws tsis tuaj yeem tshaj qhov txwv tus naj npawb ntawm torsion tig. laum cev.

(2) Xauv daim npav

Yog hais tias lub laum txoj hlua muaj ib lub hub thaum drilling, nws yuav tsum tam sim ntawd pib rauj sab sauv los yog pib lub rauj qis qis los daws daim npav, uas yog ntau concentrated tshaj qhov yooj yim nce thiab nqis quab yuam.

(3) Soak lub tso tawm tus neeg sawv cev

Immersion tso tawm tus neeg saib xyuas yog qhov feem ntau siv thiab tseem ceeb tshaj plaws los tso cov laum daig. Muaj ntau ntau hom jam tso cov neeg ua haujlwm, hais dav dav, suav nrog roj av, roj av, roj av, hydrochloric acid, av acid, dej, ntsev, dej alkali, thiab lwm yam. ntawm cov ntaub ntawv tshwj xeeb rau kev nqa cov adhesion daig laum, muaj roj-raws li, muaj dej-raws li, lawv qhov ceev tuaj yeem hloov kho raws li xav tau. Yuav xaiv tus neeg sawv cev tso tawm li cas, nyob ntawm qhov xwm txheej tshwj xeeb ntawm txhua cheeb tsam, qhov tsis tshua muaj siab zoo tuaj yeem xaiv tau ntawm qhov siab, qhov siab siab zoo tuaj yeem xaiv tus neeg sawv cev siab tshaj tawm.
