Mzere wa 150 Overshot LANDRILL 150 series kutulutsa ndi kufalitsa overshot ndi chida chakunja chosodza nsomba zonyamula, kunyamula ndi kutenga nsomba zozungulira, makamaka posodza kolala yobowola ndi chitoliro chobowola. Gwira la overshot lingapangidwe kukula kosiyanasiyana kwa nsomba, kotero overshot imodzi ikhoza kuvekedwa ndi kukula kosiyana kwa zigawo za grapple kuti usodze kukula kosiyanasiyana kwa nsomba. Mzere wa 150 Overshot womanga uli ndi zigawo zitatu zakunja: Top Sub, Bowl, ndi Standard Guide. Zoyambira ...

Mbiri ya malonda Chigayo cha gawo ndi mtundu wa chida chotsegulira zenera la chivundikiro chomwe chimaphatikiza ntchito zodula ndi kugaya chivundikiro. Chigayo cha gawo chimalowa mu chivundikirocho pamodzi ndi BHA, ndikudula kaye chivundikirocho pamalo osankhidwa. Chivundikirocho chitadulidwa kwathunthu, chidzachotsedwa mwachindunji pamalo awa. Chikafika pamlingo winawake, ntchito yotsegulira zenera la chivundikirocho imamalizidwa. Chigayo cha gawo chili ndi ubwino wa kapangidwe kosavuta, ntchito yosavuta kuti chikhale chogwira ntchito bwino kwambiri...

Flange imagwiritsidwa ntchito makamaka polumikiza zida za chitsime. Mtengo wa Khirisimasi ndi zida zina zowongolera chitsime. Mitundu yosiyanasiyana kuphatikiza flange ya ulusi wa spool wa flange ndi Flange yopanda kanthu ndi zina zotero.

Kugwiritsa Ntchito Zinthu Chitoliro cha mzere ndi chitoliro chachitsulo chomwe chimagwiritsidwa ntchito ponyamula mafuta, gasi, kapena madzi mtunda wautali. Chimapangidwa ndi chitsulo champhamvu kwambiri chomwe chingathe kupirira kupsinjika kwakukulu ndi kutentha komwe kumachitika poyendetsa. Mapaipi a mzere ayenera kukwaniritsa miyezo yokhwima yomwe imakhazikitsidwa ndi mabungwe monga American Petroleum Institute (API). API 5L ndi muyezo wodziwika bwino pa izi. Amapangidwa m'makulidwe osiyanasiyana, kuyambira mapaipi ang'onoang'ono omwe amagwiritsidwa ntchito popangira mapaipi okhala m'nyumba mpaka mapaipi akuluakulu omwe amagwiritsidwa ntchito ...

Valavu ya Choke ndi gawo lalikulu la mtengo wa Khirisimasi ndipo cholinga chake ndikuwongolera kutulutsa kwa mafuta m'chitsime, zinthu za thupi ndi zigawo za valavu ya choke zimagwirizana kwathunthu ndi API 6A ndi NACE MR-0175 Standard Specifications, ndipo imagwiritsidwa ntchito kwambiri pobowola mafuta m'mphepete mwa nyanja ndi m'mphepete mwa nyanja. Valavu ya throttle imagwiritsidwa ntchito kwambiri kusintha kayendedwe ndi kuthamanga kwa makina ambiri; Pali mitundu iwiri ya mavavu owongolera kuyenda: okhazikika komanso osinthika. Mavavu osinthika a throttle amagawidwa m'mitundu ya singano, mtundu wa sleeve yamkati ya khola, mtundu wa sleeve yakunja ya khola ndi mtundu wa mbale ya orifice malinga ndi kapangidwe kake; Malinga ndi momwe ntchito ikuyendera, imatha kugawidwa m'magulu awiri amanja ndi hydraulic. Kulumikizana komaliza kwa Valavu ya choke ndi ulusi kapena Flange, yolumikizidwa ndi non or flange. Valavu ya Choke imagwera mu: valavu yabwino ya choke, valavu ya singano ya choke, valavu yosinthika ya choke, valavu ya choke ya khola ndi valavu ya choke ya orifice, ndi zina zotero.

Kusonkhanitsa kwa stripper. Coiled Tubing BOP ndi gawo lofunika kwambiri pazida zolembera zitsime, ndipo imagwiritsidwa ntchito kwambiri powongolera kuthamanga kwa madzi pamwamba pa chitsime panthawi yolembera zitsime, kugwirira ntchito bwino komanso kuyesa kupanga, kuti tipewe kuphulika komanso kuti tipeze kupanga kotetezeka. Coiled Tubing BOP imapangidwa ndi quad ram BOP ndi Stripper Assembly. Ma FPH amapangidwa, kupangidwa ndikuyang'aniridwa motsatira API Spec 16A ndi API RP 5C7. Hydrogen Sulphide imakana dzimbiri chifukwa cha kukana kwa stress ...

Zipangizo zopukusira nsomba zimagwiritsidwa ntchito kupukusira nsomba ndi zinthu zina zogwetsera pansi, kuyeretsa zinyalala za khoma (khoma la dzenje) kapena kukonza chivundikirocho. Mfundo yaikulu ndi kupukusira nsomba kukhala zinyalala pansi pa kuzungulira ndi kukakamizidwa kwa chingwe chobowolera ndi tungsten carbide yomwe imalumikizidwa pa gawo lodulira la chida chopukusira, ndipo zinyalala zimatha kubwezeretsedwanso pansi ndi madzi obowolera.
Mitundu yambiri ya zida zopukusira ndi yofala m'mapangidwe ake, pomwe malinga ndi mawonekedwe osiyanasiyana a nsomba, zida zodulira zofanana zimafunika. Zida zodulira zomwe zimagwiritsidwa ntchito nthawi zambiri zimatha kukonzedwa mkati, kunja ndi kumapeto kwa zida zopukusira.
Pambuyo pakupanga zinthu zatsopano komanso ukadaulo wambiri m'zaka zaposachedwa, zakwaniritsa zosowa zenizeni za makasitomala ochokera ku China ndi akunja chifukwa cha magwiridwe antchito odalirika. Kupatula mitundu ndi kukula komwe kwatchulidwa muzomwe zili pansipa, tikukulandiraninso kuti mupange malinga ndi mayina apadera omwe angakwaniritse zosowa za makasitomala.

Ma valve a zipata za matope ndi zipata zolimba, tsinde lokwera, ma valve a zipata okhala ndi zisindikizo zolimba, ma valve awa adapangidwa motsatira muyezo wa API 6A. Amagwiritsidwa ntchito makamaka pa matope, simenti, kusweka ndi ntchito yamadzi ndipo ndi osavuta kugwiritsa ntchito komanso osavuta kusamalira.

Vavu yolumikizira ndi yofunika kwambiri pakugwira ntchito yolimbitsa simenti ndi kusweka m'minda yamafuta ndi migodi komanso njira yofanana yowongolera madzi othamanga kwambiri. Ili ndi kapangidwe kakang'ono, kukonza kosavuta, mphamvu yochepa, kutsegula mwachangu komanso kugwira ntchito mosavuta kotero kuti ndi valavu yabwino kwambiri pakati pa manifolds olimbitsa simenti ndi kusweka pakadali pano. (Ndemanga: valavu imathanso kutsegulidwa kapena kutsekedwa mosavuta pansi pa 10000psi.)

Kill manifold ndi chida chofunikira chowongolera kusefukira kwa madzi ndi kuphulika kwa madzi, komanso kugwiritsa ntchito ukadaulo wowongolera kuthamanga kwa madzi m'zitsime za mafuta ndi gasi.
Pa nthawi yoboola zitsime za mafuta ndi gasi, madzi oboola omwe ali m'chitsime akaipitsidwa ndi madzi oboola, kusinthasintha pakati pa kupanikizika kwa madzi osasunthika a madzi oboola ndi kupanikizika kwa mapangidwe kudzasokonekera, zomwe zimapangitsa kuti madzi asefukire komanso kuphulika.
Ngati pakufunika kufalitsa madzi obowola oipitsidwa kapena kupopera mabowo amadzimadzi pogwiritsa ntchito zitsime zamadzimadzi zomwe zimagwira ntchito bwino kuti pakhale mgwirizano wabwino, koma kuyenda bwino kwa madzi sikungatheke kudzera mu chingwe chobowola, madzi obowola omwe ali ndi ntchito yabwino akhoza kupopedwa m'chitsime kudzera mu kill manifold kuti azitha kuwongolera kuthamanga kwa mafuta ndi gasi.

Valavu yofufuzira idapangidwa ndikupangidwa motsatira zofunikira za API 6A 《Zipangizo Zofunikira za Wellhead ndi Mtengo wa Khirisimasi》, zomwe zitha kugwiritsidwa ntchito mosinthana ndi zida zofananira kunyumba ndi kunja zomwe zikugwirizana ndi API 6A Standard. Pakati pake pamakhala chitsulo chokana sulfide ndipo chingagwiritsidwe ntchito mu mkhalidwe wa H2S, thupi la vavu lopangidwa ndi chitsulo chopangidwa ndi alloy chomwe chimagwira ntchito bwino. Mitundu iwiri ya mavavu owunikira amaperekedwa ndi landrill: Mtundu wa Swing ndi Mtundu wa Lift.

Ma Integral Blade Stabilizers amapangidwa kuchokera ku 4145H alloy steel bar kapena forgings, kuzimitsidwa ndikufewetsedwa mpaka 285-341 Brinell hardness;
Zokhazikika ndi ma subs afupiafupi omwe ali ndi masamba omangiriridwa pamwamba pawo. Pothandizira BHA (Bottom Hole Assembly) pamalo enaake, zingagwiritsidwe ntchito kuwongolera njira ya chitsime. Masambawo akhoza kukhala owongoka kapena ozungulira. Masamba ozungulira amatha kukhudza dzenje pa 360°.
