Indlela yokukhetha i-Packer

Izimo kahle.

• Ukucindezelwa kahle kufanele kucatshangelwe njengoba ukukhethwa kwabapakishi kufanele kwenziwe ngamakhono 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. Abanyeukuqeda packersizomelana kuphela nokucindezela okulinganiselwe okuvela ohlangothini olulodwa.
• Ukushintsha kwengcindezi nakho kuyisici ekunyakazeni kweshubhu (elongation noma ukusikwa). Izinga lokushisa liwukucatshangelwa njengoba amanye amaphakethe azosebenza emazingeni okushisa aphezulu kunamanye.Amapaki abuyiselekayo ngokuvamile kufanele ikhawulelwe emazingeni okushisa angama-300oF aphezulu. Izinhlanganisela zokuvala ezisetshenziswa kumayunithi ophawuPackers unomphelanoma izitsha zokupakisha zizokhethelwa ukusebenza kahle kakhulu ebangeni lokushisa elinikeziwe.
• Ama-corrosive agents emthonjeni uketshezi kufanele kubhekwe. 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 ekukhethweni kwabapakishi. 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 ngamanani aphezulu kanye nezingcindezi nganoma yisiphi isizathu, umpakishi ofanele kufanele akhethwe 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 izinto zokudonsa amanzi.

• Ngokuvamile amapaki akhethwa ngenxa yokuhambisana kwawo neminye imishini. 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. Amapaki angasethwa ngemva kwe-ukuhanjiswa kwamanzi kuqediwe.
• Uma imishini yocingo izoseviswa kushubhu noma ngokubhoboza ishubhu kufanele kufezwe, kuyafiseleka ukusebenzisa amaphakethe angadingi isisindo seshubhu ukuze uwagcine emisiwe. Imisebenzi yocingo ingaqedwa ngempumelelo uma ishubhu igcinwa iqondile ngokuyibeka ngokungathathi hlangothi noma ukushuba. Lokhu kuya ngokuya kubaluleke kakhulu emithonjeni ejulile.
• Ezimweni eziningi, ukukhethwa kwamapaki kuyenziwa ukuze kusetshenziswe ama-valve okuphakamisa igesi ukuze kuvinjwe ingcindezi yokuphakamisa isuke endaweni ekhiqizayo futhi kuvinjwe igesi ukuthi ingaphephuki ekupheleni kweshubhu.
• Uma i-packer izosetshenziswa neyunithi yokumpompa induku, kuvame ukufiseleka ukuthi ishubhu libekwe ku-tension. Ukukhetha ipakethe kufanele kwenziwe ukuvumela lokhu.

Okuthandwa yikhasimende.

Kufanele kuqashelwe ukuthi izikhathi eziningi ezahlukeneizinhlobo zamapaki ingasetshenziswa 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 ukuthi ubeke ipakethe ku-ibhokisi ngokunembe kakhulu. Kwesinye isikhathi, izikhawu zokukhiqiza zisondelene kakhulu, okwenza kube nesidingo sokubeka ipakethe ngokunembayo.

Njengomkhiqizi wokupakisha ochwepheshile, ithimba le-Vigor lochwepheshe bonjiniyela bezobuchwepheshe lijwayelene nemikhiqizo yokupakisha evame ukusetshenziswa emakethe. Imikhiqizo esikunikeza yona ingaphansi kokulawulwa kwekhwalithi okuqinile ngokuhambisana namazinga e-API 11 D1 ukuze kuqinisekiswe ukuthi ikhwalithi yemikhiqizo ingahlangabezana nemvelo yesayithi eyinkimbinkimbi. Njengamanje, izinhlobo ezahlukene zemikhiqizo yokupakisha evela ku-Vigor zisetshenziswe ezindaweni ezinkulu zikawoyela emhlabeni jikelele, futhi amakhasimende anikeze impendulo enhle kakhulu ensimini, kodwa ithimba le-Vigor lisasebenza kanzima, futhi sihlala sithuthukisa umklamo wamapaki. kanye nenqubo yokukhiqiza ukuqinisekisa ukuthi yonke into ilawulwa. Uma unentshisekelo ngemikhiqizo yochungechunge lwe-Vigor's packer, sicela ungangabazi ukuxhumana nathi ukuze uthole imikhiqizo echwepheshile kanye nenkonzo yekhwalithi engcono kakhulu.
