Wireline Logging - Perforation

Ichi chinyorwa chinokurukura perforating casing nekushandiswa kwewaya kwe:

kuita remedial casing cementing, nekudzvanya kuburikidza nekuputika uye

yekutarisisa (kuumbwa) kudzvinyirirwa kuseri kwecasing.

Casing perforation

Musangano unofanirwa kuitwa usati wabirwa kuti uparadzwe, paine vashandi vanotevera varipo:

● Injiniya Wekutema/ Well Site Geologist

●Well Service Supervisor, sezvinobvira

●Wireline Operations Supervisor

●Drilling Supervisor

●Zvakanaka Saiti Drilling Injiniya

Chinangwa chikuru chemusangano ndecheku:

●Rondedzera mitsara yekushuma uye yekutaurirana.

●Kurukurai nezvekushanda.

●Kurukurai chero mamiriro ekunze, mamiriro ekunze, buri, kunyarara kweredhiyo, nguva, kushanda panguva imwe chete, nezvimwe.

Pamusoro pezvo nhaurirano yepamberi pebasa nevatemi vematanda nevanochera zvibhorani inofanira kuitwa.

Pfuti isati yaitwa mugomba, dummy run inoitwa, kutarisa kuti tubing / casing haina zvipingamupinyi. Iyo dummy inofanira kuva neOD yakafanana. sepfuti inoputika ichashandiswa. Kutema matanda kwakamboitwa pasina zvipingamupinyi zvakasangana nazvo, zvinogona kutorwa sedummy run, iyo mumamiriro ezvinhu akadaro inogona kusabatanidzwa, zvichienderana nehurukuro neBase.

Kana madzvinyiriro achitarisirwa kuburitswa panguva yekuboborwa, kana kuti nzvimbo inopindika ikapwanywa, wireline BOP, lubricator uye bhokisi rekuisa zvinhu zvinosungirirwa pawaya inosimudzwa yakanyudzwa pamusoro peBOP. Nemusoro wetambo mune lubricator, kumanikidza kuedza michina kune inodiwa kudzvanywa.

Ita shuwa kuti hapana akarasika voltages mumusoro wetambo, kana voltage inogoneka pakati perig uye casing, uye zvakare kuti iyo waya yewaya yakanyatsoiswa ivhu.

Yera kureba kwepfuti yega yega uye chinhambwe chiri pakati pekutanga kupfurwa neCCL/GR, kana zvaunganidzwa.

Panguva yose yekubata pfuti, vashandi vasingakoshi vanofanira kubviswa munzvimbo yebasa.

Kana pfuti dzapfutirwa vashandi vose vanofanira kugara kunze kwemutsara wemoto, kusvikira pfuti yapinda zvakanaka mutsime.

Kubatana kwakadzama

Mhanyai casing collar locator (CCL) uye gamma-ray (GR) logs pamusoro penguva yese kuti iburitswe. Rekodha logi pakudzika kweperforation, uye batanidza neaimbova mhanya gamma-ray matanda pane referenzi matanda. Kuona kuti pfuti iri pahupamhi chaihwo usati wapfura, kuverenga kwakadzama kunotariswa zvakazvimirira kaviri, isati yabvumidza mainjiniya ekutema matanda kupfura pfuti.

Panguva yekuputika, tarisa pane zvinoratidza kuti pfuti yarira.

Iyo dhaka nhanho mugomba inofanirwa kunyatsocherechedzwa kune kurasikirwa kana kuwana mukati menguva yese yekutema matanda, uye kunyanya pamberi pePOH. Gomba rinofanira kugara rakazara nguva dzose.

Kana iyo perforating assembly yatorwa, iva nechokwadi chekuti pfuti iri pamusoro pe lubricator isati yavhara waya-line valve.

Kana pfuti yaiswa pacatwalk inotariswa kuti haina mhosva here.

Simba perforating pfuti dzakagadzirwa, dzakagadzirwa, dzakaedzwa uye dzakaongororwa kusvika kune yepamusoro-soro indasitiri zviyero, uye isu tinotarisira kushanda nevatengi vedu kuti tibatsire mukusimudzira indasitiri yemafuta negesi. Kana iwe uchida chero pfuti dzinoputika kana kuchera uye kupedzisa kutema matanda, ndapota usazeza kubata nesu kuti uwane yakanakisa mhando yerutsigiro yechigadzirwa uye sevhisi yepedyo.
