Vharuvhu Yekuchengetedza Yakakwana (FOSV)

Vharuvhu Yekuchengetedza Yakakwana (muchidimbu FOSV) ivharuvhu yekuchengetedza yerudzi rwebhora inoshandiswa kumisa kuyerera kwemvura nepatambo yekuboorera kana tambo yekuboorera ichibviswa mutsime.

FOSV ivharuvhu yekuchengetedza inovhura muviri wese, saka haikanganisi mashandiro ezvishandiso zvakaita semabhora epakati kana zvishandiso zvekuyedza. Yakagadzirirwa kubayiwa pamusoro pechinoboorwa chepombi yekuboorera kana tambo yechubhu pasi perig uye yovharwa nekukurumidza kana tsime rikarova.

Vharuvhu yaKelly

Vharuvhu yeKelly inonziwo Kelly cock kana Gray valve. Ivharuvhu yekudzora neruoko iri mudhirowa string circulation system uye ndeimwe yezvishandiso zvinoshanda kudzivirira kuputika. Vharuvhu yeKelly yakakamurwa kuita Upper Kelly Valve neLower Kelly Valve. Vharuvhu yeKelly yepamusoro yakabatana neswivel sub naKelly. Vharuvhu yeKelly yepasi yakabatana nemagumo epasi aKelly nepamusoro pepipe yekuboorera kana magumo epasi aKelly save sub. Kutenderedza wrench yevharuvhu yekuchengetedza yakazara 90° kuti ivhurike uye ibve. Mukushanda kwekuboorera, kudzivirira tsaona dzakaipa, mavharuvhu eKelly anofanirwa kubatanidzwa kumativi ese aKelly kudzivirira kurasikirwa nekuboorera uye kuputika. Vharuvhu yeKelly cock, inova vharuvhu yebhora inoshandiswa nemaoko inoshandiswa muID yedhirowa string, ndeimwe yezvishandiso zvinoshanda zvekudzivirira kuputika.

Kelly cock yakakamurwa kuita vharuvhu yekelly cock yepamusoro uye kelly cock yepasi.
Kelly cock yepamusoro yakabatana nemucheto wepasi wepombi inotenderera uye mugumo wepamusoro wekelly. Kelly cock yepasi yakabatana nemucheto wepamusoro wepombi yekuboorera uye mugumo wepasi wekelly kana kuti yakabatana nemucheto wepasi wekelly saver subs.
Kelly cock ine oparesheni iri nyore, kelly cock inogona kuvhurwa kana kudzima nekungotenderedza oparesheni chaiyo pa90 degrees zvichienderana negwara rayo. Panguva yekuboorwa, kelly cock inofanira kubatanidzwa kumusoro nepazasi pekelly.

Mukati meBOP

Chinodzivirira kuputirwa kwemhepo mukati (Inside BOP) chishandiso chakakosha, chinogona kupatsanurwa kuburikidza neBOP kuti chibatanidzwe nemidziyo yekuboorera yakawedzerwa nekukurumidza sezvinobvira, kana kuputirwa kwemhepo kwaitika panguva yekusimudza maturusi ekuboorera, chinodzivirira kuputirwa kwemhepo mukati chine mabhenefiti akawanda akadai sekumanikidzwa kwakanyanya, chakavimbika, chiri nyore kushandisa, chinochinja nekukurumidza nezvimwewo.

Panguva yekuboorera, kubvoora kunoitika nekuda kwekusveta. Kana mvura, mafuta, utsi kana mvura zvabuda mupombi yekuboorera yakaburitswa, chinhu chinodzivirira kubvoora mukati chinofanira kubatanidzwa nekukurumidza kupombi yekuboorera. Chinhu chinodzivirira kubvoora mukati chinogona kubatanidzwa nyore nyore kupombi yekuboorera nekuti vharuvhu yechinhu chinodzivirira kubvoora iri panzvimbo yakavhurika uye mvura iri mugomba repasi inogona kuyerera kubva mumudziyo wekudzivirira kubvoora mukati iri panzvimbo yakavhurika uye mvura iri mugomba repasi inogona kuyerera kubva mumudziyo wekudzivirira kubvoora mukati. Tsvimbo yekubatsira inogona kuvhara vharuvhu nekukwesha bhaudhi rinokiya, izvozvi, chinhu chinodzivirira kubvoora mukati chinobvumira mvura kupombwa mugomba kubva kumusoro kusvika pasi, asi mvura iri mugomba haikwanise kuyerera mutambo yekuboorera uye pakupedzisira kuyerera kubva mumudziyo wekudzivirira kubvoora mukati. Chinangwa chevan yekudzivirira kubvoora chinofanira kuitwa nematanho anotevera, Bvisa chikamu chekubatsira kudzora mvura uye tanga kutenderera kwepombi.

Vharuvhu yekuchekerera yekudonhedza

Mavharuvhu ekutarisa kudzoka kwemvura panguva yekukanda uye akakodzera mamiriro mazhinji ekuboorera uko kuyerera kwemvura kuburikidza netambo yekuboorera kune njodzi uye kushanda kwakajairika kunoda mabhenefiti echikamu chakazara. Nekudzivirira kuyerera kwemvura kumusoro kuburikidza nepombi yekuboorera, asi uchibvumira mvura kuti ipombirwe pasi kuti itenderedze tsime, mavharuvhu anopa muboorera nzira yekudzora kumanikidzwa kwepombi yekuboorera kana zvichidikanwa, zvichivandudza zvakanyanya uye zvichiita kuti kudzora kwetsime kuve nyore.

Kana kuputika kwacho kwava kuda kuitika, tambo dzekubatanidza kelly dzinobviswa nekukasika dzoisa vharuvhu yekutarisa iri mupombi yekuboorera yobva yadhonzwa pasi kuenda kunzvimbo inodiwa. Saka kuputika kwacho kunogona kudzivirirwa.

Vharuvhu inoyangarara

Vharuvhu inoyangarara inodzivirira mvura yekuboorera, zvidimbu uye marara esimbi kuti asayerere achidzokera kutambo yekuboorera. Kana yakaiswa zvakanaka patambo yekuboorera, mavharuvhu aya anowedzera kudzivirira kubhururuka.

Vharuvhu inoyerera inogona kushandiswa chero kupi kubva kumusoro kusvika pasi petambo yekuboorera. Nzvimbo yayo inowanzo kuwanikwa iri muBHA (bottom hole assembly) inosanganisira bit, uye inogona kusanganisira bit sub, near bit stabilizer, mamwe ma stabilizer, float sub, cross-over sub, mud motor (top sub), drill collar, uye drillpipe. Mavharuvhu akawanda anoyerera anogona kushandiswa mutambo imwe chete, kunyangwe kurongedza kaviri hakukurudzirwi nekuda kwekukuvadzwa kunogona kuitika kwevharuvhu inoyerera kana paine kumanikidzwa kwakanyanya. Pane kudaro, paradzanisa mavharuvhu munzvimbo dzakasiyana dzezvishandiso.

Mavharuvhu ekudhonza mapaipi (DP) anowanikwa pabasa renguva dzose, H2S – 300°F service (HNBR/HSN) uye H2S – 400°F service (Viton.)
