Muaj ntau qhov laj thawj rau cov tub ntxhais tho kev puas tsuaj, feem ntau yog nrog rau cov hniav tawg, thiab lwm yam, cia peb txheeb xyuas qhov ua txhaum cai ntawm cov tub ntxhais ua txhaum cai
Coring ntsis Cov Teeb Meem Hniav Nkaus
Cov tub ntxhais laum tawm ntau yam kev hloov pauv thaum lub sijhawm drilling, uas ncaj qha ua rau cov hniav tawg.Nyob rau tib lub sijhawm, cov khoom tseem ceeb tseem yuav raug rau Eddy so, pob zeb txiav, sib tsoo thiab av nkos.Txawm hais tias cov kev raug mob no tsis ua rau cov hniav tawg thaum ntxov, lawv feem ntau xaus nrog cov hniav tawg.
Coring me ntsis av nkos hnab:
Lub npe thiaj li hu ua cov hnab av drilling txhais tau tias thaum lub pob zeb txiav tawm ntawm lub pob zeb me me, ua rau cov pob zeb txiav kom tua lub cev xyaum.Yog tias cov cuttings tsis raug tshem tawm hauv lub sijhawm, lawv yuav nthuav dav ntau dua thiab ntau dua, ua rau hauv av nkos.Cov teeb meem Mudbag tuaj yeem muaj qhov cuam tshuam tseem ceeb ntawm cov tub ntxhais tseem ceeb thiab nyiam ua ob qho teeb meem:
1.Qhov tub ntxhais tub ntxhais cov tub ntxhais tso tawm ntau tus nqi ntawm kev txiav, thiab txiav cov hniav tsis tuaj yeem kov cov kev tsim, ua rau txo cov tshuab hluav taws xob khiav ceev:
2.Qhov coring bitectulates ntau npaum li cas ntau ntawm cov vencous cuttings, ua rau nws ua zoo li cov roj tank piston kom nqus lub siab ntawm tus ncej thaum lub siab hloov kho ntau;
Coring med Eddy qhov teeb meem tam sim no:
Cov tub ntxhais me me yog thawb rau lub tiaj phab ntsa nyob rau hauv qhov kev txiav txim ntawm qhov tob tom qab tsis txaus, thiab ib sab ntawm cov tseem ceeb ntawm phab ntsa.Thaum lub pob zeb diamond txav tsis xwm yeem, nws qhov chaw instantaneous ntawm kev sib hloov yog tsis muaj geometric center ntawm lub pob zeb diamond.Lub xeev ntawm cov lus tsa suab nyob rau lub sijhawm no yog hu ua Eddy tam sim no.Thaum lub Vortex yog tsim, nws yog qhov nyuaj rau nres.Nyob rau tib lub sijhawm, vim muaj kev kub ceev, kev txav ntawm cov tub ntxhais tseem ceeb tau thawb lub ntsej muag zoo nkauj, yog li txhim kho qhov kev sib txhuam loj heev, yog li txhim kho cov eddy tam sim no ntawm Cov tub ntxhais me ntsis thiab nws thiaj li ua rau muaj kev puas tsuaj rau cov tub ntxhais me;
Dav hlau puas ntsoog teeb meem:
Nyob rau hauv thawj theem ntawm cov tseem ceeb me ntsis, vim yog tsis tsim nyog siv lub dav hlau loj heev, ib feem ntawm cov kev ntws tawm hauv qab, thiab cov feem thim rov qab mus rau saum npoo ntawm cov tub ntxhais.Lub dav hlau loj-ceev ncaj qha ncaj qha rausiab ntev, Ua ntej ua rau muaj kev puas tsuaj rau qhov chaw nruab nrab ntawm cov tub ntxhais me, thiab thaum kawg ua rau tag nrho cov tseem ceeb.
