Musoro weCasing: Ropa reHupenyu Rinobatanidza Pamusoro pePasi pevhu

Chinhu chikuru chekuvaka nzvimbo yekutakura mutoro uye kushandura kumanikidzwa kwesemidziyo yetsime—musoro wekesi. Nhasi, tiri kutarisa pane chinhu ichi chakakosha kuti tione kuti "ropa iri rinobatanidza pamusoro pepasi pevhu" rinovimbisa sei kuchengetedzeka kwakakwana kubva pamusoro kusvika pakuumbwa.

I. Tsanangudzo uye Basa: Nheyo yeMusoro weMatsime

Muchidimbu, musoro wekesi chinhu chakakosha chinobatanidza tambo yekesi iri pasi pevhu nemidziyo yemusoro wetsime. Mugumo wayo wepasi unobatanidzwa zvachose nekesi iri pamusoro uchishandisa tambo, maslips akapindurwa, kana welding; mugumo wayo wepamusoro unobatanidzwa nemuti wekrisimasi wekuboorera kana imwe chete (single ram BOP stack) kuburikidza nemaflanges kana maclamps.

Basa guru nderekumisa nekutsigira huremu hwemakesi ese ehunyanzvi anotevera uye makesi ekugadzira, zvichipa hwaro hwekugadzika kwemidziyo yese yemusoro wetsime. Sechikamu chekudzivirira tsime mukati menguva yese yekuchera, kupedzisa, uye hupenyu hwekugadzira, musoro wekesi ndiyo hwaro hwekuona kuti annular sealant pakati pechikamu chega chega chekesi uye kuwana kuparadzaniswa kwekumanikidzwa uye manejimendi.

Muenzaniso wemuenzaniso: TF 20*13 3/8-35MPa

Dudziro: Musoro wekesi reflange rine danho rimwe chete unobatanidza dhayamita yekunze yekesi re508mm (20-inch), uchirembedza dhayamita yekunze yekesi re339.7mm (13 3/8-inch), ine kumanikidzwa kwekushanda kwe35MPa.

II. Mhando neZvikamu Zvikuru: Maumbirwo eRopa reHupenyu

Misoro yekesi inoshandiswa panzvimbo iyi inonyanya kurongwa muzvikamu zveimwe nhanho, zviviri, uye zvakawanda zvichienderana nehuwandu hwezvikamu zvakasungirirwa. Pamusoro pezvo, kune misoro yakapfava yekesi, inowanzoshandiswa mumatsime emafuta anodziya muXinjiang Oilfield, ine flanges kumusoro uye tambo dzekesi pasi, kazhinji dzichishandisa ma hanger ekesi emhando ye mandrel.

Misoro yekesi inowanzo sanganisira muviri, kesi yekurembera, vharuvhu yegedhi, gauge yekumanikidza, uye screws dzakaiswa. Pakati peizvi, kesi yekurembera (inozivikanwa se "casing slip") ndiyo chinhu chakakosha chinoita kuti basa rayo guru riitwe, chinoshandiswa kumisa makesi ehunyanzvi kana makesi ekugadzira.

Kuvharwa kwepakati kwakakamurwa kuita mazinga maviri:

1. Chisimbiso Chikuru: Kukwanisa kuvhara nzvimbo yepakati pechivharo chakarembera nechivharo chepamusoro, zvichishanda sechidziviriro chikuru chekudzivirira kumanikidzwa kwepakati pechivharo.
2. Chisimbiso Chechipiri: Kuvhara kwakasimba kunoitwa neBT, P, kana zvisimbiso zvesimbi pakati pemucheto wepamusoro (mutsipa) wehanger kana pakati pehanger yakasungirirwa nemusoro wehanger (kana muti weKisimusi wakabatanidzwa wekuboorera, muti weKisimusi wakasarudzika) wakabatana neflange yepamusoro. Chisimbiso ichi chinoparadzanisa kumanikidzwa kuri pamusoro pehanger kubva panzvimbo yeannular iri pasi, chichishanda sechidziviriro chakakosha uye chinogona kuyedzwa.

III. Ruzivo Rukuru rweUnyanzvi: Nzira mbiri huru dzeKumisa neKuvhara

1. Chigadziko cheMandrel (Chakarukwa)

Chinozivikanwa panzvimbo iyi se "musoro wekaroti". Chisimbiso chayo chikuru chinoenderana nekuverenga kwakanyatsojeka kwetambo yekuisa tambo, yakaiswa pachisimbiso chesimbi chakagadzirwa nemazvo kubva kusimbi kuenda kusimbi, ine rin'i yechisimbiso che rectangular elastic sechinobatsira. Kana musoro wechubhu waiswa pamusoro payo, rin'i yechisimbiso cheBT mukamuri repasi remusoro wechubhu ichishanda pamwe nemutsipa wehanger inogona kugadzira chisimbiso chechipiri chinoshanda.

Zvinhu Zvinodiwa uye Zvinodiwa

Zvakanakira: Kubatana kwakarukwa, hapana chikonzero chekucheka kabhinzi.

Zvinodiwa Zvikuru: Kunyatsoshanda zvakanaka—kudzika kwekuisa kese kunofanirwa kuenzaniswa nemazvo, uye huremu hwakakwana hwekugara hunofanira kuve nechokwadi; zvikasadaro, kuvhara zvakanaka hakugone kuwanikwa.

2. Chigadziko chemhando yekutsvedza

Zvichibva pachimiro chekutsvedza, zvakanyanya kupatsanurwa kuva mhando yeW, mhando yeWE, uye mhando yeWD, zvese zvichibatana kuburikidza nematsvedza akawanda anosangana nekasi.

Mhando yeWD (Reverse Slips): Yakagadzirwa chete pamisoro yekesi yechikamu chekutanga (pamusoro). Kuisa hakudi kuverenga kureba kwepombi yemuchina; inongoda kuve nechokwadi chekuti denderedzwa neukobvu hwemadziro enzvimbo yekesi (kudzivirira kubatana) zvinosangana nezvinodiwa, kucheka nekupukuta kesi kuti ive yakati sandara (dhigirii rakatwasuka ≤ 0.5°, divi rekunze rakakweshwa ne10° chamfer), wobva waipinza zvakananga. Mugumo wepasi wekesi wakagadzirwa nezvisimbiso zviviri zveBT kuti zvivharwe nemadziro ekunze ekesi.

Rudzi rweW nerudzi rweWE: Dzose dzinoshandisa slip taper nehuremu kuti dzishandise rabha seals. Rudzi rweW runoshandisa huremu hwesimbi yekumisikidza yetambo yekumisikidza kuti dzishandise chisimbiso chepazasi kuti chisimbiswe pakutanga, chine huremu hwakanyanya hwekumisikidza uye chisimbiso chakavimbika. Rudzi rweWE runoshandisa kusimbisa screws dzekumusoro nemaoko kuti dzisimbise ringi yekumisikidza, yakakodzera zviitiko zvine kumanikidzwa kwakaderera kwekumisikidza.

IV. Kiyi Yekugadzirisa Panzvimbo: Kushandisa uye Kutarisira Maoko Ekushandisa

Munguva yekuboorera, kudzivirira kuti maturusi ekuboorera asapfeke pamusoro pechisimbiso mukati memusoro wekesi uye akanganisa kunaka kwechisimbiso chekupedzisira, chisimbiso chekumboora (rudzi rwakatambanudzwa rwunoshandiswa muTarim Oilfield nedzimwe nzvimbo) chinofanira kuiswa panguva yekuboorera. Chisimbiso chekumboora chinounzwa uchishandisa maturusi akakosha uye chinogadziriswa uye chinoganhurirwa nemasikuru akagadzikwa.

Zvinhu Zvakakosha Zvekuongorora

Mushure mekufamba kwega kwega uchibuda mugomba, tarisa kana sleeve yekupfeka yapera uye simbisa kuti zviratidzo zve screw zviri mukati memuganhu. Kana sleeve yapera, musoro wetsime unofanira kugadziriswazve nekukasika. Zvikasadaro, sleeve yekupfeka kwenguva refu inogona kupera nepasleve yekupfeka kana kunyange mudumbu re casing, zvichikonzera njodzi huru dzekuchengetedza tsime.

Muchidimbu, taongorora zvakarongeka mufananidzo wese wemusoro wekasi—“ropa rehupenyu” hwemusoro wetsime. Nehurongwa hwayo hwekumisikidza hwakarurama uye zvipingamupinyi zvekuvhara mazinga akawanda, inotsigira huremu hwenzvimbo dzese dzekudzora nekugadzira tsime, ichikamura kumanikidzwa kweannular kuita mazinga akarongwa. Sehwaro hwakasimba hwezvinodzora zvese zvinoshanduka, musoro wekasi ndiwo purojekiti huru yekutakura kuchengetedzeka kwemusoro wetsime, kuparadzanisa kumanikidzwa kwekugadzirwa, uye kuwana hunhu hwetsime mukati mehupenyu hwese. Kusimbisa hwaro uhwu kunosimbisa vimbiso yakakosha yehupenyu hwese hwetsime.
