Ubwino wa kubowola casing

1. Chepetsani nthawi yopunthwa ndi kubowola. Zimatenga nthawi 5-10 mwachangu kugwiritsa ntchito chingwe kukweza ndikusintha pobowola kuposa ndodo yachikhalidwe;
2. Sungani mtengo wogula, mayendedwe, kuyendera, kukonza, ndi kusintha kokhudzana ndikubowola mapaipindi kubowola kolala;
3. Chifukwa chakuti nthawi zonse pamakhala chosungira mwa mwana wobadwa bwino, palibenso mphamvu yopopera pachitsime pamene chitoliro chobowola chikugwedezeka kuti chiwongolero chikhale bwino;
4. Kuthetsa swabbing zotsatira ndi kuthamanga pulsation chifukwa kutsitsa kubowola chitoliro;
5. Kuzungulira kwamatope kosalekeza kungathe kusungidwa pamene chobowolacho chimakwezedwa ndi chingwe cha waya, chomwe chingalepheretse kudzikundikira kwa cuttings ndikuchepetsa kuchitika kwa kukankha bwino;
6. Kupititsa patsogolo liwiro la annulus mmwamba ndi pansi ndi chikhalidwe cha kuyeretsa bwino kubadwa. Pamene matope amaponyedwa m'bokosi, mkati mwake ndi wamkulu kuposa wa chitoliro chobowola, zomwe zimachepetsa kutayika kwa hydraulic, motero kuchepetsa mphamvu ya mpope wamatope wa makina obowola. Pamene matope abwerera kuchokera kumtunda wa annular pakati pa casing ndi khoma labwino, chifukwa cha kuchepa kwa dera la annulus, liwiro lobwerera m'mwamba likuwonjezeka, ndipo kudulidwa kwa kubowola kumatheka;
7. Ikhoza kuchepetsa kukula kwazitsulo, kuchepetsa kapangidwe kake, ndi kuchepetsa mtengo wazitsulo.
8. Chombo chobowola ndi chopepuka komanso chosavuta kusuntha ndi kugwira ntchito. Kuchuluka kwa ntchito yamanja ndi ndalama zidzachepetsedwa;
9. Sipafunikanso kugwiritsa ntchito chitoliro chobowola
10. Kubowola kwa casing kumachokera ku casing imodzi, ndipo sikofunikiranso kugwiritsa ntchito njira yoboola yofanana ndi mapaipi awiri kapena atatu. Choncho, kutalika kwa derrick kumatha kuchepetsedwa ndipo kulemera kwa maziko kungachepetse; kwa makina akuya otembenuza bwino, kumanga Chingwe chobowola potengera kubowola kamodzi, kapangidwe kake ndi kulemera kwa derrick ndi substructure ndizosavuta kuposa zomwe zimatengera pobowola.
