Mhando dzeDrill pipe uye Tubular Cutter

Kune akawanda akasiyana marudzi etubular cutters anowanikwa muoiri & gasi indasitiri. Maapplication anowanzo kugera pombi yekuboorera, coil tubing, kana kudzoreredza tambo yekupedzisa kubva mutsime nekucheka tubular joint kana pakucheka kuburitsa packer assembly.

Sezvinoiswa zvese mugomba, zvakakosha kuronga uye kusarudza chaiyo yekucheka kune yega yega application pamwe chete neiyo nzira yekuisa. Sezvineiwo, mabasa ese ekucheka anosarudzwa kuti aitwe nepombi yekuboorera kana tambo yekupedzisa mukumanikidzana, kazhinji huremu hwetambo kuwedzera gumi muzana, pazvinogoneka. Kukuvadza kune casing, kana kuseri kwetubing, kunogona kuitika kana iyo isiriyo cutter yakasarudzwa. Vamwe vanocheka havakwanisi kucheka munzvimbo yegasi, saka chiyero chemvura uye mhando inogona kuve chinhu chekufunga nezvacho. Kana chinoputika chikachekwa chine wireline tirakita inofambiswa, panogona kuve nenjodzi huru yekuti tirakita inogona kuparamura kana kutadza kuchekwa. Yese maturusi ekucheka anofanirwa kushandiswa mukati meiyo yakatarwa tembiricha uye kumanikidza miganho.

Mhando dzeCuter paMusika

Sarudzo dzekucheka dzinogona kuiswa zvakanyanya muzvikamu zvinotevera:

• Zvinoputika Zvinocheka
• Electromechanical Cutters
• Chemical Cutters
• Radial Cutting Torch

ZvinoputikaCanoti:

Zvinoputika zvinocheka zvinogona kuputswa pasi zvakare mune zvinotevera maapplication.

• Drill Collar Severing Colliding Tool:Aya anoshandiswa kucheka pombi mumabasa ekudzoreredza, uchishandisa chaiyo nguva inoputika machaji kucheka nepakati makora ekudhirowa uye zvimwe zvinorema-basa zvinhu. Kuedza kwekucheka kunofanira kuitwa pamusoro peiyo yakarova. Kukuvadza kwakakosha kwepombi uye kupatsanurwa kuchaitika panguva yekuita.
• Shaped Charge Cutters:Aya anoshandisa machaji anoputika kuti atarise kuputika mujeti yesimbi inopinda uye inocheka zvinhu zvakanangwa. Iwo anoshandiswa pakuita severance chaiyo mukuita downhole. Kupisa kwe tubular kunotarisirwa panguva yekucheka asi yakagadziridzwa kuderedza izvi. Vamwe vanocheka vakagadzirirwa kupatsanura kora uye kusunungura tubular nenzira iyi. Kufunga kunodiwa kana uchigadzira kupedzisa kuti uone kuti iyo yekucheka inogona kunyatsoiswa panzvimbo yekucheka kuburitsa packer. Zamu rekumhara pamusoro pemutakuri rinogona kubatsira mune izvi.

Ongorora: Nepo zvinoputika zvinocheka zvakajairwa munzvimbo yemafuta zvinogona kunetsa kutakura kuenda kutsime nenguva pfupi nekuda kwezvirambidzo zvekuchengetedzwa kwenyika. Vanoputika vanocheka vanogona kucheka netambo mukumanikidzana kana kumanikidza.

Kemikari uye Radial Kucheka Torch:

• Chemical Cutters:Aya anoshandisa makemikari akaita sebromine trifluoride kunyungudutsa simbi zvakachena pasina tsvina. Iwo anonyanya kubatsira munzvimbo dzakaoma kana dzakaoma-kusvika, zvisinei kune akakosha ekuchengetedza anodiwa kuti ukwanise kuendesa iyi michina nekuda kwemakemikari anokuvadza zvakanyanya uye bi-zvigadzirwa.
• Radial Cutting Torch (RCT):Inoshandisa plasma jet kucheka zvinhu. Ichi chishandiso hachiputike uye chinogona kuendeswa nekukurumidza pasi rose nekuda kwezvirambidzo zvishoma zvekufambisa, kunyangwe panogona kunge paine zvimwe kunze kune izvi.
• Pamusana pechiito chavo chekucheka hapana kuputika kwe tubular. Iyi mhando yechishandiso ndiyo chete sarudzo yekucheka coil tubing.

Ongorora: Nekuda kwechimiro chezvishandiso izvi zvakakosha kuti zviitwe pakati nemazvo. Zviviri zvezvishandiso izvi zvinogona kuve nyore kunamatira kumadziro echubhu panguva yekucheka. Yakanyatsogadziriswa netambo mutension pamwe ne10%.

Electromechanical Cutters:

• Electromechanical Cutters:Aya macheki anoshandisa kutenderera kana kudzoreredza misoro yekucheka kana mablades anofambiswa nemagetsi uye anotariswa kubva pamusoro panguva yekucheka. Aya marudzi ezvishandiso akanakira nharaunda umo zvinoputika kana makemikari zvinoisa njodzi, kana kwazvisingagoneke kuzvitakura kuenda kutsime. Nepo vazhinji vatengesi vezvishandiso vachitaura kuti maturusi avo anogona kucheka mune zvese kushushikana uye kumanikidzana, tambo mukunetsana yaizogara yakakwana. Iko tambo iri mukutsikirirwa, kutariswa kunodiwa kudzivirira nyaya dzine maturusi ane bladed anonamira pane tubular kupaza, kana chishandiso chinomira panguva yekucheka chisingakwanisi kutangazve nekuda kwekukanganisa mukugadzira kwavo. Kudzosa kwechishandiso kunogona kuve kwakaoma kana magetsi mapfupi akaitika panguva yekucheka. Sezvinoita nevazhinji vanocheka, chaiyo centralization yakakosha pakubudirira.

Ongorora: Imwe mabhenefiti makuru emagetsi ekucheka emagetsi pane dzimwe nzira dzekucheka ndiko kugona kupedzisa kucheka kwakawanda panguva imwechete yakanaka mutsime.

SimbaKwete-kuputika Downhole Cutter

• Isina-kuputika Downhole Cutter ine mudziyo wekumisa chikepe uye a
• Iyo anchoring device inobata chigadziro chekucheka kumadziro emukati wepombi kuti achekwe, kudzivirira chigadziro kubva pakufamba panguva yekucheka; iyo combustor inogadzira yakanyanya-tembiricha uye yakanyanya kunyungudika yakanyungudutswa yesimbi mvura inokwesha uye inobvisa pombi, nokudaro ichizadzisa chinangwa chekucheka.
• Sarudzo yekuchengetedza inotariswa, kana chiridzwa chisingakwanisi kuvharwa panguva yebasa, kuburikidza nekupinza kwe230mA ikozvino kana kusimudza waya yekupfuura 1.6T simba kugera mapini uye kusunungura tambo yekushandisa.

Inotevera inyaya yebvunzo yemumunda inoitiswa nechikwata cheVigor chemainjiniya panzvimbo yemunda wemafuta kuChina kuti itariswe:

Parizvino kudzivirira kuvharika, kadhi yepombi yepasi, pre-chekwa 2-3/8" tubing, kucheka kudzika 825.55m. TheΦ43 Wireline Non-explosive Downhole Cutter yakashandiswa pakuvaka, uye uremu hwekumisa hwakasimudzwa ne8t, uye kucheka kwakagadzirwa. kubudirira kupedzwa pa804.56m, uye nguva yose yekucheka yakanga inenge 6min. The incision yakanaka, hapana flanging, hapana dhayamita yekuwedzera.

Kusvika ikozvino, iyo Inoputika Downhole Cutter kubva kuVigor yave imwe yeanonyanya kufarirwa pasi pepipe yekuchera pombi maturusi, chishandiso chave chichizivikanwa zvakanyanya nevashandisi vekupedzisira nekuda kwekuvimbika kwayo kwepamusoro, kana iwe uchifarira Vigor's Non-kuputika Downhole Cutter. , ndapota usazeza kubata nesu.
