Ungakhetha kanjani i-Packer?

Well Izimo.

● Ukucindezela komthombo kufanele kucatshangelwe njengoba ukukhethwa kwabapakishi kufanele kwenziwe ngamandla afanele okucindezela komthombo. Kuyadingeka ukwazi ukuthi ukuhluka kwengcindezi kuzoba kusuka phezulu noma phansi kompakishi futhi uma umehluko uzoshintsha ukusuka kolunye uhlangothi kuya kolunye ngesikhathi sokuphila komthombo. Abanye abapakishi bokuqedela bazomelana kuphela nokucindezela okulinganiselwe okuvela ohlangothini olulodwa.

● Ukushintsha kwengcindezi nakho kuyisici ekunyakazeni kweshubhu (ukwelula noma ukufinyela). Izinga lokushisa liwukucatshangelwa njengoba amanye amaphakethe azosebenza emazingeni okushisa aphezulu kunamanye. Amaphakethe abuyiselekayo ngokuvamile kufanele akhawulelwe emazingeni okushisa angama-300oF aphezulu. Izinhlanganisela zokuvala ezisetshenziswa kumayunithi ophawu kubapakishi unomphela noma izitsha zokupakisha zizokhethwa ukuze kusebenze kahle kakhulu ebangeni lokushisa elinikeziwe.

● Izinto ezibolayo ezisemanzini omthombo kufanele zicatshangelwe. Ngokuvamile, amaphakethe abuyiselekayo awenzi kahle emithonjeni ene-H2S ephezulu. Izikhathi eziningi, ama-alloys asetshenziswa lapho kwakhiwa ipaka kufanele akhethwe ukuze amelane nezinto ezilimazayo azohlangana nazo.

● Ubude besikhathi sokukhiqiza buwukucatshangelwa okuyinhloko ekukhetheni amapaki. Uma indawo kulindeleke ukuthi ikhiqize iminyaka eminingi ngaphandle kwesidingo somsebenzi wokulungisa, kungase kufiseke ukusebenzisa isipakishi sohlobo oluhlala njalo noma isethi ye-hydraulic set retrievable packer. Kodwa-ke, uma kulindelekile ukuthi umsebenzi wokulungisa emthonjeni uzodingeka phakathi nesikhathi esifushane, kungase kufiseleke kakhulu ukusebenzisa isethi yomshini wokupakisha.

● Uma umthombo uzophathwa nge-asidi noma izinto ze-frac noma uphonswe kuwo ngezinga eliphezulu nezingcindezi nganoma yisiphi isizathu, kufanele kukhethwe umpakishi ofanele Ukwehluleka kwepaki ngokuvamile ukwenzeka ngesikhathi sokwelapha. Ukufinyela kwamashubhu kungase kube kubi kakhulu ngesikhathi sokwelashwa. Ukufinyela kungabangela abapakishi ababuyiselekayo ukuthi bakhululwe, noma kungabangela izici zophawu ukuthi ziphume ku-seal bore kumpakisheli ongunaphakade noma isitsha se-packer bore.

Ukuhambisana Nezinye Izisetshenziswa Zokudonsa.

● Ngokuvamile amapaki akhethwa ngenxa yokuhambisana kwawo nezinye izinto zokusebenza. Isibonelo, lapho amasistimu e-hanger esetshenziswa namasistimu okuphepha angaphansi komhlaba alawulwa phezulu, kuyafiseleka ukusebenzisa amasethi amasethi ama-hydraulic. Amaphakethe wesethi ye-Hydraulic avumela opharetha ukuthi afake futhi asethe uhlelo oluphelele lokuphepha kanye nesihlahla ngaphambi kokusetha abapakishi. Uketshezi lwamanzi lungase lukhishwe ngoketshezi olulula kuyilapho umthombo ulawulwa ngokuphelele. Abapakishi bangasethwa ngemva kokuqedwa kokukhishwa koketshezi.

● Uma impahla yocingo izoseviswa kushubhu noma ngokubhoboza amashubhu kuzofezwa, kuyathandeka ukusebenzisa amaphakethe angadingi isisindo seshubhu ukuze uwagcine emile. Imisebenzi yocingo ingaqedwa ngempumelelo uma ishubhu igcinwa iqondile ngokuyibeka ngokungathathi hlangothi noma ukushuba. Lokhu kuya ngokuya kubaluleke kakhulu emithonjeni ejulile.

● Ezimweni eziningi, ukukhethwa kwamaphakethe kuyenziwa ukuze kusetshenziswe amavalvu okuphakamisa igesi ukuze kuvinjwe ingcindezi yokuphakamisa isuke endaweni ekhiqizayo futhi kuvinjwe igesi ekuphepheni ekugcineni kweshubhu.

● Uma ipaketha izosetshenziswa neyunithi yokumpompa induku, ngokuvamile kuyafiseleka ukuthi ishubhu libekwe ngokushuba. Ukukhetha ipakethe kufanele kwenziwe ukuvumela lokhu.

Okuthandwayo Kwekhasimende.

Kufanele kuqashelwe ukuthi ezikhathini eziningi, izinhlobo eziningana ezahlukene zamapaki zingasetshenziswa ngempumelelo ekufakweni okufanayo. Izikhathi eziningi, umpakishi angase akhethwe ngu-opharetha ngoba ube nempumelelo enhle ekuyisebenziseni esikhathini esidlule.

Ezomnotho.

Ezomnotho zingase zibe yisici ekukhethweni kwabapakishi. Kwezinye izimo, u-opharetha kufanele agcwalise kahle ngendlela eyonga kakhulu futhi uzokhetha ipakethe ngenxa yezindleko zayo eziphansi.

Ukusetha Ukunemba.

Uma i-packer isethwe ulayini we-conductor kagesi, kungenzeka ukubeka ipakethe ku-casing ngokunembe kakhulu. Kwesinye isikhathi, izikhawu zokukhiqiza zisondelene kakhulu, okwenza kube nesidingo sokubeka ipakethe ngokunembayo.

Okungenhla yizici zereferensi zokukhetha ipakethe. I-Vigor inesipiliyoni seminyaka eminingi embonini kawoyela negesi futhi izimisele ukutshala imali ku-R&D ukuze kuqinisekiswe ukuthi i-Vigor inganikeza izixazululo zekhwalithi ephezulu kumakhasimende ethu. Amapaki avela ku-Vigor aklanywe futhi akhiqizwa kusetshenziswa amazinga e-API 11D, futhi asetshenziswe ensimini ekhaya naphesheya futhi aye aqashelwa ngazwi linye ngamakhasimende. Uma unemibuzo mayelana nokukhetha ipakethe elungile noma uma unentshisekelo kwamanye amathuluzi okumba nokuqedela embonini kawoyela negesi, sicela ungangabazi ukuxhumana no-Vigor ngemikhiqizo namasevisi wekhwalithi engcono kakhulu.
