I-Perforating isebenza kanjani ku-Oyela Negesi?

Ukubhoboza kahle kusho ukudala izimbobo ku-casing kanye nosimende ukuvumela ukuxhumana phakathi komthombo kanye nokwakheka.

Ngemva kokuba umthombo usubhodliwe nokufakwa kwegobolondo, uketshezi olwenziwayo oluhlanganisa ama-hydrocarbon awakwazi ukuhamba luye emthonjeni futhi yingakho ukubhoboza njalo kwenziwa ngaphambi kokuphuka noma ukusebenza kokukhiqiza.

Izindlela Ezivamile Zokubhoboza

Izindlela ezintathu ezivame ukusetshenziswa kakhulu ekudaleni ukubhoboza emthonjeni ukubhoboza ijethi, ijethi eqhumayo, nokusebenzisa isibhobo senhlamvu.

I-Jet Perforating

Ukubhoboza ijethi kwenziwa kusetshenziswa iziqhumane ezimise okwenzeke ezidala amagagasi omfutho lapho ziqhunyiswa.

Lawa maza okucindezela acindezela noma yini endleleni yawo okuhlanganisa i-casing nosimende futhi adale imigudu evumela ukuxhumana phakathi komthombo kanye nokwakheka.

Izibhamu ezibhobozayo eziphethe lezo ziqhumane zivame ukugitsheliswa emthonjeni olayini wezintambo, amashubhu, noma amashubhu ahlanganisiwe.

Enye yezinzuzo eziyinhloko zokusebenzisa ishubhu ukudlulisa izibhamu ezibhobozayo emthonjeni yikhono lokungena ujule emithonjeni echezuke kakhulu.

Le ndlela yokusebenzisa ishubhu ukudlulisa izibhamu ezibhobozayo emthonjeni ibizwa ngokuthi i-TCP, okusho ukubhoboza okudluliswa ngamashubhu.

Isizathu esenza ukuthi izintambo zocingo zingahambi kahle kweminye yemithombo ukuthi intambo yensimbi eguquguqukayo kuyilapho amashubhu ahlanganisiwe aqinile kakhulu futhi avumela ukudluliswa kwamandla angcono ethuluzini.

I-wireline ngakolunye uhlangothi idinga iphampu phansi ngoketshezi ukuze ifinyelele ekujuleni okuqondiwe emithonjeni evundlile.

I-Abrasive Jetting Perforating

Ukubhoboza kusetshenziswa ijethi elimazayo kwenziwa ngokumpompa ingxube yoketshezi, isihlabathi, namakhemikhali ngombhobho odala imbobo ku-casing.

Ijetting e-abrasive ngokuvamile yenziwa kusetshenziswa ishubhu eligoqiwe.

Ububi bejethi eqhumayo ukuthi imvamisa ihamba kancane futhi idinga amathuluzi amaningi kunokubhoboza ijethi ngeziqhumane.

Inzuzo ukuthi ungakha ama-perforations amakhulu ngosayizi omncane wokwakheka.

Isiqhumiso senhlamvu

Enye indlela yokubhoboza engasadumile kakhulu ukusebenzisa isibhamu esidala izimbobo egodini ngokudubula izinhlamvu eziklanywe ngokukhethekile.

Enye inselele ngeziqhumane zezinhlamvu ukuthi izinhlamvu zishiywa ekubunjweni futhi zidale izindawo zokungena eziphansi ezingaba nomthelela omubi ekukhiqizeni.

Ama-bullet perforators ayaziwa futhi ngokudala ukuphuka okungafuneki kusimende.

Ezinye izindlela zokubhoboza ezingajwayelekile ukusebenzisa amalaser, ukujetha amanzi, ukumpompa i-asidi, nokusebenzisa izisiki ezisebenza ngomshini.
