Mitundu ya Drill pipe ndi Tubular Cutter

Pali mitundu yambiri yosiyanasiyana ya ma tubular cutter omwe amapezeka mumakampani amafuta & gasi. Ntchito nthawi zambiri imakhala yodula chitoliro chobowola, machubu, kapena kuchotsa chingwe chomaliza pachitsime podula cholumikizira cha tubular kapena podula kuti mutulutse chophatikizira.

Monga momwe zilili ndi kutumizidwa ku chitsime, ndikofunikira kukonzekera ndikusankha chodulira choyenera pa ntchito iliyonse pamodzi ndi njira yake yotumizira. Moyenera, ntchito zonse zodulira zimakonda kuchitidwa ndi chitoliro chobowola kapena chingwe chomaliza movutikira, nthawi zambiri kulemera kwa chingwe kuphatikiza 10%, ngati kuli kotheka. Kuwonongeka kwa casing, kapena kuseri kwa chubu, kungachitike ngati wodula wolakwika asankhidwa. Ocheka ena sangathe kudula pamalo omwe ali ndi mpweya, kotero kuchuluka kwa madzi ndi mtundu wake kungakhale chinthu choyenera kuganizira. Ngati chodulira zophulika chiyenera kuyendetsedwa ndi thirakitala yamawaya, ndiye kuti pangakhale chiwopsezo chachikulu kuti thirakitala itha kugawanika kapena kulephera kuyimitsa. Zida zonse zodulira ziyenera kugwiritsidwa ntchito mkati mwa malire awo a kutentha ndi kupanikizika.

Mitundu ya Cuter Pamsika

Zosankha zodulira zimatha kugawidwa m'magulu otsatirawa:

• Zodulira Zophulika
• Zodula za Electromechanical
• Chemical Cutters
• Radial Cutting Torch

ZophulikaCakuti:

Zodulira zophulika zitha kugawidwa m'mapulogalamu otsatirawa.

• Drill Collar Severing Colliding Chida:Izi zimagwiritsidwa ntchito podula mapaipi pobwezeretsa, pogwiritsa ntchito zida zophulika zomwe zachitika panthawi yake kuti zidutse makhola obowola ndi zida zina zolemetsa. Kuyesera kudula kuyenera kupangidwa pamwamba pa kugunda. Kuwonongeka kwakukulu kwa chitoliro ndi kugawanika kudzachitika panthawiyi.
• Ma Shaped Charge Cutters:Izi zimagwiritsa ntchito zida zophulika kuti ziwongolere kuphulika mu ndege yachitsulo yomwe imalowa ndikudula zomwe mukufuna. Amagwiritsidwa ntchito pochiza matenda amtundu uliwonse. Kuwotcha kwa tubular kumayembekezeredwa panthawi yodula koma kwasinthidwa kuti kuchepetsa izi. Odula ena amapangidwa kuti azigawa kolala ndikumasula tubular motere. Kuganiziridwa kumafunika popanga kumaliza kuonetsetsa kuti chodulacho chikhoza kukhazikitsidwa bwino kuti chidule kuti chitulutse paketa. Nipple yokhazikika pamwamba pa paketi ingathandize pa izi.

Chidziwitso: Ngakhale zodulira zophulika ndizofala m'malo opangira mafuta, zitha kukhala zovuta kunyamula kupita kuchitsime posachedwa chifukwa cha zoletsa zachitetezo cha dziko. Odula ophulika amatha kudula ndi chingwe mu kukanikiza kapena kukanikizana.

Chemical and Radial Cutting Torch:

• Chemical Cutters:Izi zimagwiritsa ntchito mankhwala monga bromine trifluoride kusungunula zitsulo bwino popanda zinyalala. Ndiwothandiza makamaka m'malo ovuta kapena ovuta kuwapeza, komabe pali njira zazikulu zodzitetezera zomwe zimafunika kuti muthe kugwiritsa ntchito zidazi chifukwa cha mankhwala owopsa kwambiri komanso bi-products.
• Radial Cutting Torch (RCT):Amagwiritsa ntchito plasma jet kudula zinthu. Chida ichi sichimaphulika ndipo chikhoza kutumizidwa mofulumira padziko lonse lapansi chifukwa cha zoletsa zochepa zamayendedwe, ngakhale pangakhale zina zosiyana ndi izi.
• Chifukwa cha ntchito yawo yodula palibe kuwomba kwa tubular. Zida zamtunduwu nthawi zambiri zimakhala njira yokhayo yochepetsera machubu a coil.

Zindikirani: Chifukwa cha momwe zidazi zilili ndikofunikira kuziyika pakatikati moyenera. Zida zonsezi zitha kukhala zosavuta kumamatira ku khoma la tubing panthawi yodula. Amayatsidwa bwino ndi chingwe chokokerana kuphatikiza 10%.

Zodula za Electromechanical:

• Zodula za Electromechanical:Odulawa amagwiritsa ntchito mitu yozungulira kapena yobwerezabwereza yomwe imayendetsedwa ndi magetsi ndikuyang'aniridwa kuchokera pamwamba panthawi yodula. Zida zamtunduwu ndi zabwino m'malo omwe zida zophulika kapena mankhwala zimatha kukhala pachiwopsezo, kapena pomwe sizingatheke kuzitengera kuchitsime. Ngakhale ogulitsa zida ambiri amanena kuti zida zawo zimatha kudula ndi kukanikizana, chingwe chokhazikika chingakhale choyenera nthawi zonse. Kumene chingwe chikukanikizidwa, m'pofunika kuganiziridwa kuti tipewe zovuta zomwe zida zokhala ndi blade zimakakamira pakubowola kwa tubular, kapena ngati chida chikuyimilira pakudulidwa komwe sikungathe kuyambiranso chifukwa cholephera kupanga. Kupeza zida kumatha kukhala kovuta ngati njira yachidule yamagetsi imachitika panthawi yodula. Monga momwe zimakhalira ndi ocheka ambiri, kukhazikika kolondola ndikofunikira kuti apambane.

Zindikirani: Ubwino umodzi waukulu wa odula ma electromechanical pa njira zina zodulira ndikutha kumaliza mabala angapo panthawi imodzi yabwino mchitsime.

MphamvuWodulira Downhole Wosaphulika

• Chodulira cha Downhole chosaphulika chimakhala ndi chida chozingira ndi a
• Chipangizo chomangirira chimangirira chida chodulira ku khoma lamkati la chitoliro kuti lidulidwe, kuteteza chidacho kuti chisasunthike panthawi yodula; chowotcha chimapanga madzi otentha kwambiri komanso othamanga kwambiri omwe amatsuka ndi kutulutsa chitoliro, motero amakwaniritsa cholinga cha kudula.
• Njira yachitetezo imaganiziridwa, pomwe chida sichingasinthidwe panthawi yantchito, kudzera pakulowetsa kwa 230mA kapena kukweza waya wopitilira mphamvu ya 1.6T kumeta zikhomo ndikumasula chingwe.

Zotsatirazi ndi zomwe gulu la mainjiniya a Vigor adachita pamalo opangira mafuta ku China kuti afotokoze:

Kutsekeka kwachitetezo chochulukirachulukira, khadi yopopera pansi, machubu odulidwa kale 2-3/8", kudula kuya 825.55m. kutsirizidwa bwino pa 804.56m, ndipo nthawi yonse yodula inali pafupi 6min. The incision ndi bwino, palibe flanging, palibe kukula m'mimba mwake.

Mpaka pano, Non-explosive Downhole Cutter kuchokera ku Vigor yakhala imodzi mwa zida zodulira zitoliro zodziwika kwambiri za downhole, chidacho chadziwika kwambiri ndi ogwiritsa ntchito mapeto chifukwa chodalirika kwambiri, ngati muli ndi chidwi ndi Vigor's Non-explosive Downhole Cutter. , chonde musazengereze kulumikizana nafe.
