1.Perforation density
Ndiyo nhamba yezvibodzwa pamita yehurefu. Mumamiriro ezvinhu akajairwa, kuti uwane huwandu hwekugadzira huwandu hunoda yakakwira perforation density, asi mukusarudzwa kweperforation density, haigone kuve isina muganho wekuwedzera density, inofanirwa kufunga zvinotevera zvinhu:
Kunyanya kukura kwegomba kunogona kukonzera kukuvara kwecasing zviri nyore.
Iyo gomba density yakakura kwazvo, mutengo wakakwira;
Kuwedzeredza kwegomba density kuchanetsa maoperation emangwana.
Kana iyo pore density idiki kwazvo, kuwedzera kwekubereka kunooneka kana pore density ichiwedzerwa. Asi kana iyo gomba density ichiwedzera kune imwe kukosha, mhedzisiro yegomba density pachiyero chekugadzira haisi pachena. Chiitiko chinoratidza kuti kana gomba kuzara kuri 26 ~ 39 maburi/m, huwandu hwekugadzira huchawedzerwa nemutengo wakaderera.
2. Gomba dhayamita
Ndiyo parameter yakakosha inoratidza saizi yekuboora. Iyo perforation saizi inowanzo iri pakati pe5 kusvika 31mm (0.2 kusvika 1.23in), zvichienderana nerudzi rwekuboora uye huwandu hwechaji. Neimwe uwandu hwezvombo zvepfuti, kuvhurika kwakadzika-kunopinza kwemukati kudiki, uye iyo yekuvhuvhuta hombe-yakakura. Iyo yakakura kuwanda kwezvombo, ndiko kukura kweaperforation.
Chimwe chinhu chinokanganisa buri ndiko kuchena pakati pepfuti inoputika uye casing. Iyo perforating effect ndiyo yakanaka kana pfuti inoputika iri pakati petsime. Mukushanda kweperforating, zvinodikanwa kutora matanho akakodzera kuchengetedza pfuti inoputika pakati petsime.
3. Chikamu
Iyo Angle pakati pezviviri zvakatenderedza perforations inonzi phase Angle. Phase zvakare ine simba guru pakubudirira. Parizvino, pane zvitanhatu zvinowanzoshandiswa perforating zvikamu zve 0°, 45°, 60°, 90°, 120° uye 180°. Mukugadzirwa kweanisotropic, kubereka kunowedzera zvakanyanya kana chikamu cheAngle chichichinja kubva pa180 ° kusvika 0 ° kana 90 °, asi chibereko hachichinje zvakanyanya kana chikamu cheAngle chichichinja pakati pe0 ° ne90 °.
Huwandu hukuru hwekuyedza uye mashandisirwo emumunda anoratidza kuti tsime reoiri rine chibereko chakaderera kana chikamu chegomba chiri 0 °. Kana chikamu chiri 120 ° uye 180 °, simba rekugadzira riri pakati; Zvishoma kumusoro pa45 ° chikamu; Kana chikamu chiri 60 ° uye 90 °, simba rekugadzira ndiro rakakwirira
4. Perforation kupinda kudzika
Zvinoreva kureba kwegwaro rekuboora. Iyo perforation yekupinda yakadzika inotarirwa nerudzi rweperforation charge chimiro uye huwandu hwemambure. Yakadzama yekupinda mhando hombe yekuchaja, kudzika kwekupinda kwakareba, kudzika kwekupinda kunowanzo muhupamhi hwe146 ~ 813mm, uye kudzika kwekupinda kunowedzera nekuwedzera kwepfuti. Chiyero chekugadzirwa kwemafuta Wells chinowedzera nekuwedzera kwekudzika kweperforation, asi maitiro ehuwandu hwehuwandu hunowedzera zvishoma nezvishoma, kureva, kana gomba rakadzika richiwedzera kune imwe kukosha, chiyero chekugadzira hachizowedzera zvakanyanya.
