Kodi Wireline Conveyed Perforating ndi chiyani

Wireline yoperekedwa perforating ndi njira yokhazikika, yotsimikiziridwa yodalirika yosakayikira. Nthawi zambiri imakhala yotsika mtengoperforating njiranjira ndi yodalirika kuposa njira zina. Zotsatira za kuwombana kolakwika zimachepetsedwa ndi kumasuka komwe mfuti zimatha kuchotsedwa padzenje ndikuyambiranso. Chifukwa cha kulemera kwa mfuti, kagawo kakang'ono kokha kangathe kuphulika panthawi iliyonse yothamanga mu dzenje.

Kutalika kwapakati kuyenera kupangidwa mothamanga kangapo, komwe koyambirira kokhako kumatha kuchitika pansi pamikhalidwe yabwino ya underbalance. Kutengera kuzama ndi kulingalira kwina, monga kuchedwa kupeza chete wailesi kapena malamulo oletsa kugwiritsa ntchito zida zophulika usiku, nthawi yogwiritsira ntchito yomwe ikufunika pakuthamanga imatha kusiyana kuchokera pasanathe ola limodzi mpaka maola angapo.

Chifukwa chake, kuphulitsa nthawi yayitali ndi mfuti zamawaya kumatha kutenga masiku angapo, zomwe zitha kukhala zokwera mtengo kwambiri ngati cholumikizira chili pamalopo. Kugwiritsira ntchito mfuti zamawaya ndiyo njira yotetezeka kwambiri yoboola mawaya yomwe ilipo, ndipo pali zochitika zochepa zomwe zimanenedwa za kuphulitsa mwangozi pamtunda kapena pansi. Kubowoleza kwa waya sikufuna chotchingira pamalopo ndipo nthawi zambiri kumagwiritsidwa ntchito poboola madera owonjezera opangira zitsime.

The Perforating Gun Assembly & Mechanism

Gulu lamfuti la mawaya limapangidwa ndi mutu wa chingwe, cholozera kolala kapena chida cha gamma ray, ndi zida za masika kapena maginito zoyika mfuti pachibowo ndi mfuti yokha. Mitundu inayi ikuluikulu ya mfuti za perforating za waya zimatha kusiyanitsa ndipo zikuwonetsedwa mu Chithunzi 1. Zonse zimafanana pakugwira ntchito ndipo zimasiyana kokha momwe zigawozo zimasonkhanitsira.

Cable Head

Mutu wa chingwe umapereka kugwirizana kwa makina ndi magetsi pakati pa chingwe ndi mfuti. Kulumikizana kwamakina pakati pa chingwe ndi mutu ndikocheperako kuposa chingwecho chomwe chimalola chingwe kuti chikokedwe ngati mfuti ikhala.anakakamira mdzenje. Nthawi zambiri amatchulidwa kuti malo ofooka. Mutu wa chingwe umapangidwa ndi khosi lodziwika bwino kuti mulole muyezozida zophera nsombakuchira zingwe zida ngati mfundo yofooka yathyoledwa. Zamfutikuthamanga pogwiritsa ntchito chingwe chachikulu, khosi ili ndi mbiri yosalala kulola chinkhoswe ndikuwombera mopambanitsa/kupambana msonkhano. Mosiyana ndi zimenezi, khosi lausodzi lokhazikika la waya limaperekedwa kwa mfuti zazing'ono.

Malo Opangira Kolala Mu Waya Waya Wotumiza Kutulutsa

Cholozera kolala kapena chida cha gamma ray chimayika mfutiyo pamalo ozama omwe atsimikiziridwa ndendende ndi miyeso ya chipika chotsegula kapena zida zomaliza. Gamma-ray zida amagwiritsidwa ntchito pang'ono chifukwa cha kufooka kwawo komanso kusavuta kwake komwe chipika cha kolala chingagwiritsidwe ntchito polumikizana mwakuya. Nthawi zambiri, chida cha gamma ray ndi collar locator (GR-CCL) zimayendetsedwa mophatikizana musanayambe kuthamangira kuti mulole kuya kwake.poyizonimakola okhudzana ndi zipika zowunikira dzenje lotseguka kuti zitsimikizike.

Kufunika kowonjezera kuthamanga kwa GR-CCL kungapewedwe powonetsetsa kuti chida cha gamma ray chikuphatikizidwa ndichipika cha simentiza kupanga mtundu wa casing. Kuzama kwa kolala kumagwiritsidwa ntchito kukonza zolakwika mumiyeso yozama yomwe imapangidwa poyendetsa mfuti yobowola mu dzenje. Tiyerekeze kuti chipika chotsegula cha gamma ray chilibe mawonekedwe okwanira kulola kulumikizana ndi chipika cha kolala.

Zikatero, pangakhale kofunika kuyendetsa chipika cha nyutroni chokhala ndi chipika cha kolala kuti mudziwe kuya kwa makola a casing. Zovuta zogwirizanitsa ma collar log runs osiyanasiyana zimatha kubweretsa zolakwika pakuzindikiritsa makola amodzi pomwe zolumikizira zonse zimafanana kutalika kwake. Chifukwa chake, ndi chizolowezi kuthamangitsa kaphatikizidwe kakang'ono (pup joint) mu chingwe cha casing pamwamba pa malo osungiramo madzi. Izi zimatsimikizira kuti makola a casing amadziŵika mosavuta komanso mofulumira, kuchepetsa chiopsezo choboola mozama.

Position Chipangizo

Kwa mfuti zing'onozing'ono za m'mimba mwake, zomwe sizimadutsa mu 360 °, zipangizo zoyikapo zimayikidwa pansi pa kolala kuti zitsimikizire kuti mfutiyo ikuyang'ana njira yoyenera ya azimuthal mu chitsime. Ikathamangitsidwa, malo a azimuthal a mfuti pachitsime amazindikira mtunda wodutsa mumadzi amchere omwemtengo wofananandege iyenera kuyenda isanalowe m'bokosi.

Nthawi zambiri, mtunda uwu uyenera kuchepetsedwa kuti ukwaniritse mapangidwe apamwamba kwambiri komanso magwiridwe antchito abwino kwambiri. Chipangizo cha kasupe kapena maginito chimagwiritsidwa ntchito pofuna kuonetsetsa kuti mfutiyo imagwiridwa motsutsana ndi casing, zomwe zimachepetsa kuima pakati pa thupi lamfuti ndi casing poyang'ana kuwombera. Kupyolera mu chubu, kuphulika kwa madera apamwamba azambiri kumalizaamafuna kuti akatemera kuwombera ndi orientation kuti amapewa kuwonongeka kwa chingwe yaitali kumaliza.

Wireline Inanyamula Mfuti Yophulika

Mfutiyi imayikidwa pansi pa msonkhano wa perforating. Mfutiyi imakhala ndi chophulitsira magetsi, kapena chipewa chophulitsa, cholumikizidwa kumapeto kwa chubu cha zophulika chomwe chimatchedwa chingwe chophulitsa kapena prima cord . Chingwe chowombera chimayenda kutalika kwa mfuti. Ndi kukhudzana thupi ndi aliyense zooneka milandu.

Mfuti ikawomberedwa, chipewa chophulitsa chimayambitsa kuphulika kwa chingwe cha prima, chomwe chimayambitsanso milandu iliyonse. Mu mfuti zonyamulira zopanda pake, chipewa chowombera chimayikidwa pansi pamfuti, ndipo mfuti imathamangitsidwa kuchokera pansi mpaka pansi. Detonator sichidzayambitsa primacord ngati madzi amadzimadzi alipo chifukwa cha kutayikira, kuteteza kuphulika kwapansi ndi kugawanika kwa mfuti komwe kungayambitse. Mfuti zamtundu wa capsule zotsika mtengo komanso zotsika mtengo zimakhala ndi kapu yophulika pamwamba ndipo zimawombera kuchokera pamwamba kupita pansi. Tiyerekeze kuti nthawi yopitilira iyenera kubowoleredwa.

Zikatero, zigawo zamfuti nthawi zambiri zimalumikizidwa palimodzi (pamene kuphulika kwamfuti kwa gawo limodzi lamfuti kumayambitsa mwachindunji kuphulika kwa gawo lotsatira) ndikuwombera ngati mfuti imodzi. Kumene mafupipafupi angapo ayenera kubowoledwa, mfuti zikhoza kuphatikizidwa ndi kuthamanga pamodzi ndiyeno zimawombera payekhapayekha pa kuya kofunikira. Mapangidwe a mfuti kuti athamangitsidwe amapindula pogwiritsa ntchito ma diode ndi makina osinthika mumfuti ya downhole.

Monga katswiri wodziwa kupanga mfuti zoboola, Vigor yawononga nthawi ndi ndalama zambiri mu R&D ndikupanga mfuti zophulitsa, kungopatsa makasitomala athu zida zotsogola kwambiri padziko lonse lapansi. Mpaka pano, mfuti yophulika kuchokera ku Vigor yakhala ikugwiritsidwa ntchito m'malo ambiri opangira mafuta ku Ulaya, Middle East, Central Asia, South Asia, America ndi madera ena, ndipo wakhala akudziwika kwambiri ndi makasitomala. Ngati muli ndi chidwi ndi kubowola pansi, kumaliza, zida zodula mitengo pamakampani amafuta ndi gasi, chonde musazengereze kulumikizana nafe kuti mupeze zinthu zaluso kwambiri komanso ntchito yabwino kwambiri.
