Mhando dzeThread dzePipe Drill dzeAPI: Gwaro Rekupedzisira reKubatanidza Kuboorera

Muindasitiri yekuchera, chikamu chimwe nechimwe chinoita basa rakakosha mukubudirira kwebasa. Pakati pezvinonyanya kukosha imhando dzeAPI drill pipe thread—izvi zvikamu zvisingaimbwe zvinovimbisa kutapurirana zvakanaka kwesimba remugomba uye kutenderera kwemvura. Kunzwisisa kubatana uku hakusi kungoziva chete; inzira yekuwedzera kushanda zvakanaka kwekuchera, kuchengetedzeka, uye purofiti.

Gwaro iri rekupedzisira richaongorora zvakadzama mhando dzakasiyana dzema API drill pipe thread, kubva pakubatanidza kwakajairika kusvika pakubatanidza kwakasarudzwa. Tichaongorora hunhu hwavo hwakasiyana, mamiriro ezvinhu anoshanda, uye kukanganisa kwavo kukuru pakushanda kwekuchera, zvichikubatsira kuita sarudzo dzakachenjera kuti uwane kushanda kwepamusoro.

Chii chinonzi API Drill Pipe Thread?

Matambo e API drill pipe anoreva ma connections akajairwa ari pama drill pipe anoenderana nezvinodiwa neAmerican Petroleum Institute (API), kunyanya API Specification 5DP.

Kubatana uku kweAPI kunovimbisa kuti tambo yekuboorera inoenderana, yakasimba, uye inoshanda zvakanaka mukuvhara mafuta negasi.

Chii chinonzi tambo yepombi yekuboorera?

Shinda dzepombi yekuboorera dzinoreva zvivakwa zvekubatanidza zvemakanika zvakagadzirwa pamagumo echikamu chega chega chepombi yekuboorera. Kuburikidza nekubatana uku, chikamu chimwe nechimwe chepombi yekuboorera chinogona kubatanidzwa pamwe chete kuti chigadzire tambo yekuboorera inoenderera mberi. Shinda idzi dzakagadzirwa nokungwarira dzine ma profiles chaiwo, tapers uye saizi kuti ive nechokwadi chekubatana kwakachengeteka, kwakasimba kunogona kutumira torque inotenderera, kumanikidzwa kudzika uye kumanikidzwa kwemvura yekuboorera kwakajairika.

Mugumo wechirume unonzi "pin", une shinda dzekunze pamusoro pawo; mugumo wechikadzi, unozivikanwa se "bhokisi", une shinda dzemukati dzinoenderana. Kugadzirwa kweshinda idzi kwakakosha kuchengetedza kusimba kwepombi yekuboorera pasi pekumanikidzwa kwakanyanya kunosangana nako mukuboorera, zvichibatsira kudzivirira kutadza kunodhura uye kuona kuti tsime rakavakwa zvakanaka.

Mhando dzeThread dzePipe Drill dzeAPI Drill

Sangano reAmerican Petroleum Institute (API) rakagadzira mhando dzakasiyana-siyana dzema thread emapaipi ekuboorera, izvo zvakakosha pakuona kuti ma drill pombi anowirirana, akasimba, uye akabatana zvakanaka. Mhando idzi dzema thread dzakagadzirwa nokungwarira kuti dzikwanise kubata kumanikidzwa kwakanyanya uye zvinodiwa pakushanda panguva yekuchera mafuta negasi.

Kunzwisisa mhando imwe neimwe chinhu chakakosha pakuvandudza mashandiro ekuboorera uye kudzivirira kutadza kukuru.

Pazasi pane mhando huru dzema thread e API drill pipe: Threads dzakajairwa (dzakajairika)

Tambo yeAPI Regular (REG) inzira yekubatanidza yakasimba uye yakagadzirwa zvakanaka, yakagadzirirwa kushandiswa pakuboorera. Ine tambo yakadzika uye dhizaini yakatetepa, iyo inogonesa kubatana kwakachengeteka pakati pepini nebhokisi repombi yekuboorera. Dhizaini iyi inoita kuti torque ne axial loads zvigone kufambiswa zvakanaka kuburikidza netambo yekuboorera.

Kunyangwe zvichishandiswa zvakanyanya (kunyanya pakubatanidza madhiri ekubatanidza uye zvikamu zvekubatanidza maburi epasi), dhayamita yemukati me REG threads idiki pane yemamwe marudzi ekubatanidza maAPI. Izvi zvinotungamira mukurasikirwa kwakanyanya kwekumanikidzwa kana mvura yekuboorera ichitenderera, asi kuvimbika kwayo uye nyore kushandisa kunoita kuti ive sarudzo yakajairika mune dzakawanda mamiriro ekuboorera akajairwa.

Mashinda eKutsvaira Mukati (IF)

Dhizaini yeshinda dzeAPI Internal Flush (IF) inotarisa pakuvandudza mashandiro ehydraulic. Yakagadzirwa kuti igadzire nzira yemukati yakatsetseka, inoenderera mberi ichipinda nepakati, nokudaro ichideredza kutenderera uye kurasikirwa nekumanikidzwa kana mvura yekuboorera ichipfuura nepaipi yekuboorera. Iyi dhayamita yemukati "yekugoorera" inowanikwa nemagumo emapaipi akakora (akapfurwa), ayo anogadzika shinda pasina kuganhurira nzira yemvura.

Kuyerera kwemvura uku kuri nani kunobatsira zvikuru mumabasa anoda kutenderera kwakanyanya kwemvura, kana pakuboora matombo anoburitsa zvidimbu zvakawanda, sezvo zvichigona kuchenesa madziro emvura uye kutonhodza chidimbu chemvura zvinobudirira. Pasinei nekushanda kwayo zvakanaka kwe hydraulic, dhayamita yakakura yekunze kwechombo chekushandisa dzimwe nguva inogona kukonzera kupera simba kwakanyanya mumatombo anokwenya zvakanyanya.

Mashinda eAPI Full Hole (FH) ndeimwe mhando yekubatanidza yakagadzirirwa kuwedzera nzira yemukati memvura. Kufanana nemashinda eIF, dhayamita yawo yemukati inowanzo kuve yakakura. Dhizaini iyi inoderedza kuramba kwemvura yekuchera, izvo zvakakosha pakuchengetedza kushanda zvakanaka kwe hydraulic—kunyanya mukucherwa kwedhayamita hombe kana mashandisirwo anoda pombi yepamusoro.

Kubatana kweFH kunonyanya kubatsira mumamiriro ezvinhu apo kuwedzera mwero wekudzoka kwemvura uye kuderedza kurasikirwa nedzvinyiriro ndizvo zvinonyanya kukosheswa. Kubatana uku kunowanzo shandiswa pamapombi ekuboorera ane dhayamita yakakura uye kunosarudzwa kana kushanda kwepamusoro-soro kwekutumira mvura kuburikidza netambo yekuboorera kwatanga, nokudaro zvichibatsira kuwedzera kumhanya kwekuboorera uye kuchenesa tsime remvura zvinobudirira.

Kubatana Kwakanyorwa Nenhamba (NC)

Kutangwa kweAPI Numbered Connection (NC) series kunovavarira kugadzirisa nekutsiva magadzirirwo ekare eAPI thread, kusanganisira mamwe ma IF neFH connections. Zita rekuti "NC" rinoteverwa nenhamba, iyo inomiririra dhayamita ye pitch ye thread (mu inches ne tenths of an inch), nokudaro ichigadzira tsika yakajeka uye inowirirana yemazita.

Ma "NC connectors" ane hunyanzvi hwakasiyana-siyana uye akasiyana-siyana emashandisirwo muindasitiri, nekuda kwehukuru hwawo hwakajairwa uye mashandiro akanaka kwazvo. Dhizaini yawo inogona kutsungirira torque yakasimba uye kushushikana kwekudhonza, zvichiita kuti akwanise kudzika kwakasiyana-siyana kwekuboorera uye mamiriro akaomarara enzvimbo. Kuchinjana kunoita kuti kuve nyore kutarisira zvinhu uye kunoita kuti zvienderane pakati pemichina yakasiyana yekuboorera.

Kubatana Kwakajairwa Kwemafudzi Anotenderera (SRSC)

Standard Rotating Shoulder Connection (SRSC) iboka rakakura rinosanganisira mafudzi akasiyana-siyana akabatana akatetepa anoshandiswa zvakanyanya muindasitiri yekuboora, akadai semaAPI threads (semuenzaniso, REG, IF, FH, uye NC). Mafambiro aya anoshandiswa pa "fudzi" rakanyatsogadzirwa kuti "rigadzire" (kuwana kubatana kwakasimba), nokudaro zvichipa kuvharwa kwekutanga uye kutumira mitoro inodzvinyirira. Mashinda aya anonyanya kushanda pakudhonza mafudzi pamwe chete uye kutamisa mitoro inotenderera.

Dhizaini yeSRSC yakakosha pakuboorera tambo zvakanaka, zvichiita kuti kuungana nekupatsanurwa kwetambo zvikurumidze uye zvakachengeteka ukuwo ichivimbisa kushanda zvakanaka. Inoshanda zvakanaka munzvimbo dzine torque yakakwira uye ine simba rakawanda, saka inowanzo shandiswa pakuboorera, ichiumba muviri mukuru wetambo zhinji dzinoboorerwa kubva pamusoro kusvika pasi pegomba.

Nzira yekubatanidza mapendekete maviri (DS)

Double Shoulder (DS) Connection idhizaini yepamusoro yeshinda yepamusoro kana yepamusoro inopa mashandiro akavandudzwa zvakanyanya kana tichienzanisa nekubatanidza kweAPI kwakajairwa, sezvo ichiisa fudzi rechipiri pasi peshinda yakajairwa. Iyi fudzi rechipiri rinobata mushure meyekutanga, richipa mamwe mapoinzi ekubata uye kugona kwekutakura mutoro. Dhizaini iyi itsva inowedzera simba rekubatana uye kuramba kudhonzwa.

Dhizaini yefudzi rakawedzerwa mukubatana kweDS inovabvumira kutsungirira torque yakakwira uye inopa simba rakanaka rekudzivirira kuneta, zvichiita kuti vakwanise kushandiswa munzvimbo dzakaoma dzekuboora dzakadai sekuboora kure, kuboora kwakatwasuka, kana kushanda munzvimbo dzakaoma, dzinokwenya. Kusimba kwavo kwakawedzerwa kunobatsira kuvandudza kushanda zvakanaka kwekuboora uye kuderedza nguva isingabudisi zvibereko.
