Cov txheej txheem thiab txheej txheem ntawm cov yeeb nkab hlua sib dhos

Cov txheej txheem ntawm cov yeeb nkab hlua sib dhos:

1.clear tsim tsim cov ntsiab lus

(1) Master tus qauv ntawm downhole yeeb nkab hlua, lub npe, specification, siv cov downhole cov cuab yeej, ib theem zuj zus thiab ncua sij hawm yuav tsum tau.

(2) Master lub sij hawm ntau lawm, interlayer thickness thiab xuab zeb ntau lawm dej.

(3) Master lub casing puab txoj kab uas hla, qhov txoj kab uas hla yuav txo, casing dab tshos qhov chaw, casing puas, roj spacing, perforated zoo interval thiab dag hauv qab qhov.

(4) Xam qhov ntev ntawm tubing ntawm cov cuab yeej drilling.

2.Clean, tshuaj xyuas thiab ntsuas tubing thiab lwm yam cuab yeej downhole

(1) Chav ua kom huv lub raj.

(2) Xyuas seb lub raj xa dej puas zoo lawm.

(3) Txheeb xyuas tias cov cuab yeej zoo, qhov loj me thiab cov xov txuas txuas yog tsim nyog thiab tsis muaj kev puas tsuaj, thiab ua tau raws li qhov yuav tsum tau siv.

(4) Xyuas seb cov yeeb nkab lub cev puas muaj qhov tawg, qhov, khoov thiab corrosion.

(5) Siv tus qauv sab hauv kab ntsuas ntsuas kom dhau lub raj.

(6) Muab cov raj tsis tsim nyog rau hauv kev sib cais thiab ua ib qho cim.

(7) Lub raj yog npaj kom zoo nkauj ntawm cov yeeb nkab txuas, lub dab tsho yog tig rau ntawm lub qhov dej, thiab tom qab ntawd ntsuas nrog cov kab xev ntsuas, thiab sau rau ntawm cov ntaub ntawv tubing, qhov kev txiav txim ntawm tubing thiab daim ntawv txiav txim yuav tsum sib haum. los ntawm ib.

(8) Cov kab xev hlau siv yuav tsum tsim nyog tom qab kuaj, thiab nws qhov ntev yog 15m (los yog 25m). Thaum ntsuas, straighten daim kab xev steel kom tsis txhob curvature los yog distortion ntawm steel daim kab xev.

(9) Thaum ntsuas tubing, yuav tsum tsis pub tsawg tshaj 3 tus neeg, thiab qhov yuam kev ntawm cov hlua hlua ntsuas 3 zaug yuav tsum tsis txhob ntau tshaj 0.02%.

(10) Ntsuas qhov ntev ntawm lub twj tso kua mis thiab tubing sub nrog ib daim kab xev ntsuas thiab sau rau hauv cov ntaub ntawv tubing.

(11) Tshawb xyuas lossis ntsuas qhov ntev ntawm cov roj muab tub lim, lub tes tsho muab tub lim, tubing hanger, thiab lwm yam.

3. Cov kev cai tshwj xeeb rau cov yeeb nkab hlua sib dhos

(1) Xam qhov ntev ntawm tubing xav tau los ntawm kev xav, ntsuas thiab xaiv cov tubing, thiab txuas cov cuab yeej downhole.

(2) Cov hlua yeeb nkab yuav muab tso rau raws li qhov kev txiav txim khiav thiab qhov tseeb qhov tob yuav raug xam. Cov kev sib tw khiav, kev tso kawm ua ntu zus thiab cov ntaub ntawv tubing yuav tsum sib haum ib los ntawm ib qho.
