Zvikonzero uye mhinduro dzekunamira kwekuchera

Kunamatira, kunozivikanwawo sekuti differential pressure sticking, ndiyo tsaona inonyanya kunamira panguva yekuboorwa, ichikonzera anopfuura 60% yekukundikana kunamira.

Zvikonzero zvekuramba uchiverenga:

(1) Tambo yekuboorera ine nguva yakareba isingachinji mugomba;

(2) Musiyano wekumanikidzwa mutsime wakakura;

(3) Kusashanda zvakanaka kwemvura inocherwa uye kunaka kwekeke revhu kunokonzera kukweshana kukuru;

(4) Hunhu husina kunaka hwechibhorani.

Hunhu hwekunamira chibooreso:

(1) Kunamatira kuri mumamiriro ezvinhu asingachinjiki etambo yekuboorera kunogona kuitika, sezvo nguva isingachinjiki ichaitika yakanamatira, ine hukama hwakasimba nehurongwa hwemvura yekuboorera, mashandiro, chimiro chekuboorera, mhando yegomba, asi panofanira kunge paine maitiro asingachinjiki.

(2) Mushure mekunamira chibooreso, nzvimbo yekunamira haizove iyo drill bit, asi iyo drill collar kana drill pipe.

(3) Usati wanamatira uye wapedza, kutenderera kwemvura inocherwa kwakajairika, kuyerera kwekutumira nekuburitsa zvinhu kunze kwakaenzana, uye kumanikidzwa kwepombi hakuchinji.

(4) Mushure mekunamatira pachibhorani chakanamirwa, kana chiitiko chacho chisina kuitwa nenguva, nzvimbo yakanamirwa inogona kukwira kumusoro, kana kutofamba yakananga pedyo neshangu yekesi.

Kudzivirira kunamira:

Zvinodiwa zvakajairika, nguva yekuboorera tambo haifanirwe kudarika maminetsi matatu. Kureba kwechibooreso chimwe nechimwe hakusi pasi pe2m, uye kutenderera hakusi pasi pe10 cycles. Mushure mebasa, huremu hwesuspension hunofanira kudzoserwa pahuremu hwepakutanga.

Kana chidhiraivho chiri pasi pegomba uye chisingakwanise kufamba nekutenderera, zvinodikanwa kudzvanya 1/2-2/3 yehuremu hwakasungirirwa hwechishandiso chekudhiraivho padhiraivho kuitira kukotama tambo yekudhiraivho yepasi, kuderedza nzvimbo yekubatana pakati petambo yekudhiraivho nekeke redhaka remadziro, uye kuderedza kunamira kwese.

Pakuboorwa kwakajairika, zvakaita sekunge pombi kana hosipaipi yaparara, pombi yekelly haifanirwe kuiswa pamusoro petsime kuti igadziriswe. Kana kuboorwa kwacho kwakamira, kucharasikirwa nemukana wekudzvanya pasi nekutenderedza tambo yekuboorwa.

Kurapa kwechibooreso chinonamira:

(1) Mabasa akasimba

Kunamatira kunowedzera kuoma nekuwedzera kwenguva. Nokudaro, muchikamu chekutanga chekuwanikwa kwetsvimbo, simba guru rinofanira kuitwa mukati memutoro wakachengeteka wemidziyo (kunyanya dhiri nesystem yekumisikidza) uye tambo yekuboorera. Haipfuure muganho wakachengeteka wemutoro wekubatanidza kusina simba, uye huremu hwetambo yese yekuboorera hunogona kudzvanywa padanho rakaderera, uye kutenderera kwakakodzera kunogonawo kuitwa, asi haigone kudarika huwandu hwemuganho hwekutenderera kwepombi yekuboorera.

(2) Vhura kadhi

Kana tambo yekuboorera iine chirongo panguva yekuboorera, inofanira kutanga nyundo yepamusoro nekukasika kana kutanga nyundo yepasi pasi kuti igadzirise kadhi, iro rakasimba kupfuura simba riri nyore rekukwira nekudzika.

(3) Nyika chinhu chinoburitsa zvinhu

Mushonga wekunyudza ndiyo nzira inonyanya kushandiswa uye inokosha yekuburitsa chibhora chakabatwa. Kune mhando dzakawanda dzemushonga wekuburitsa jam, zvakazara, zvinosanganisira mafuta asina kucheneswa, mafuta edhiziri, mafuta anosanganiswa, hydrochloric acid, ivhu, mvura, mvura yemunyu, mvura yealkali, nezvimwewo. Mupfungwa yakamanikana, zvinoreva mhinduro yakakosha inoumbwa nezvinhu zvakakosha zvekusimudza chibhora chakabatwa chakabatanidzwa, kune mafuta, kune mvura, huwandu hwazvo hunogona kugadziriswa sezvinodiwa. Maitiro ekusarudza mushonga wekuburitsa, zvichienderana nemamiriro ezvinhu chaiwo enzvimbo yega yega, tsime rine pressure shoma rinogona kusarudzwa paunoda, tsime rine pressure yakawanda rinogona kusarudza mushonga wekuburitsa wakanyanya.
