The Perforating Gun Assembly & Mechanism

Mfuti yoboola pa waya imakhala 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 zoboola mawaya zimatha kusiyanitsa ndipo zikuwonetsedwa. 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 mfutiyo ikhala.anakakamira mdzenje. Nthawi zambiri amatchulidwa kuti malo ofooka. Mutu wa chingwe umapangidwa ndi khosi lodziwika bwino kuti lilole 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. Zida za gamma-ray sizimagwiritsidwa ntchito pang'ono chifukwa cha kufooka kwawo komanso kusavuta kwake komwe chipika cha kolala chimatha kugwiritsidwa ntchito polumikizana mwakuya. Nthawi zambiri, chida cha gamma ray ndi collar locator (CCL) zimayendetsedwa mophatikizana isanayambe kuthamanga kuti athe kuzama kwenikweni kwapoyizonimakola okhudzana ndi zipika zowunikira dzenje lotseguka kuti zitsimikizike.

Kufunika kowonjezera CCL kuthamanga kumatha kupewedwa powonetsetsa kuti chida cha gamma ray chikuphatikizidwa ndichipika cha simentiza kupangamtundu wa casing. Kuzama kwa kolala kumagwiritsidwa ntchito kukonza zolakwika mumiyeso yozama yomwe imapangidwa pamene akuyendetsa mfuti ya perforating 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, kubowola kwa madera apamwamba azambiri kumalizaamafuna kuti akatemera kuwombera ndi orientation kuti amapewa kuwonongeka kwa chingwe yaitali kumaliza.

Wireline Inanyamula Mfuti Yophulika

Mfutiyo 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 chingwe choyambirira. Chingwe chowombera chimayenda kutalika kwa mfuti. Ndi kukhudzana thupi ndi aliyense zooneka milandu.

Mfuti ikawomberedwa, chipewa chowombera chimayambitsa kuphulika kwa chingwe cha prima, chomwe chimayambitsanso milandu iliyonse. Mu mfuti zonyamulira zopanda pake, chipewa chowombera chimayikidwa pansi pamfuti, ndipo mfutiyo imawombera kuchokera pansi mpaka pansi. Detonator sichidzayambitsa primacord ngati madzi amadzimadzi alipo chifukwa cha kutayikira, kuteteza kuphulika kwapansi ndi kugawanika kwa mfuti komwe kungayambitse. Mfuti zotsika mtengo komanso zotsika mtengo kwambiri 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.

Mfuti zophulika kuchokera ku Vigor zimapezeka mu njira zotumizira za TCP ndi WCP, zomwe zonse zimapangidwa motsatira ndondomeko ya SYT5562-2016, ndipo nthawi zonse tikukonza zoyendetsa ndi zoyikapo kuti katunduyo afike bwinobwino pamalo a kasitomala. Ngati muli ndi chidwi ndi zida zathu zamfuti za perforating, chonde musazengereze kulumikizana nafe kuti mupeze zogulitsa ndi ntchito zabwino kwambiri.
