Amathuluzi Okudonsa

1. Ukuqedwaabapaki

Uchungechunge olu-5 lwama-packer angu-21 luye lwakhiwa eminyakeni eyi-15 edlule ukuze kuhlangatshezwane nesidingo semisebenzi yasensimini, okuhlanganisa ama-packer atholakala ngomshini, ama-packer atholakala ngomshini, ama-packer atholakala ngomshini kanye nama-packer amakhulu alengayo. Ama-packer akhethwa ngokuhambisana nohlobo lomthombo (oqondile, ovundlile noma ophambukile), izimo zemithombo (ezijulile noma ezijulile kakhulu, i-HTHP, ukumunca, ukuqhekeka kwesigaba) kanye nosayizi abahlukahlukene be-casing (4).〞～9 5/8〞)

1) Iphakethe eliziqinisekisayo le-ZYseal

I-ZYl packer ihlanganisa indlela yokusetha ngogesi kanye nokuhlola isivalo. Ingcindezi eqinile ngemva kokupompa ukuze ibekwe i-packer ivame ukukhombisa ukuhlukaniswa okuhle phakathi kwezingqimba yi-packer. Ama-ZYpacker amabili engeziwe angafakwa entanjeni eyodwa enobude obungaphezu kwamamitha angu-500 futhi ama-tube ayadingeka kokubili phezulu kwe-packer ephezulu kanye naphansi kwe-packer engezansi.

Ingcindezi yokusebenza: 50MPa (7250psi)

Izinga lokushisa lokusebenza: 150c(302F) 180C(356F)

2) Iphakethe le-KC Khydraulic

I-KC hydraulic packer iyi-packer eyodwa esebenza kahle kakhulu ephinde isetshenziswe yohlobo lwe-hydraulic expansion. Isakhiwo se-valve esakhelwe ngaphakathi se-packer sizovalelwa ku-aliquid sealid sealid, silondoloze ukusebenza kahle kwesikhathi eside kwe-packer, sikhulule ipayipi lapho ingcindezi yangaphakathi icindezelwa, ingcindezi yomjovo iye ku-annulus. I-valve sealing element ngaphakathi kokuvulwa kokukhipha uketshezi, i-sealing element recovery.

Ingcindezi Yomsebenzi: 50MPa (7250psi)

Izinga lokushisa elifanele: 120 degrees (248 ℉)

3) I-DM Unidirectionallan i-hydraulic enamathele umphakeli

I-DM unidirectional anchored hydraulic packer iyi-packer yohlobo lokukhiqiza ebekwe emanzini, ine-anchoring eyodwa, futhi ikhishwa ngokuphakamisa intambo yepayipi. Ukusetshenziswa kwendlela yokukhiya eyingqayizivele akugcini nje ngokudlala indima yokukhiya, kodwa futhi kuthuthukisa umthamo wokuthwala. Ingasetshenziswa ngokwehlukana noma ngezigaba eziningi, futhi ingasetshenziswa kanye nezinye izipakethi.

Ingcindezi Yomsebenzi: 50MPa (7250psi)

Izinga lokushisa elifanele: 120 degrees (248 ℉)

2、amathuluzi okuqinisa

Amathuluzi okufaka usimende ayi-9 adalwe futhi asetshenziswa emasimini asekhaya. Lawa ahlanganisa ikhola yokubhoboza, i-hanger, i-receptacle, ikhola yokufoatha, isicathulo esintantayo, ipulaki yerabha.

3. ukubhoboza kanye nezinto zokugcwalisa

Iklama futhi ikhiqize izinhlobo eziningi zezinto zokubhoboza nokuqeda, okuhlanganisa isilingi sesilayidi, i-hydraulic anchor, i-downhole valve, i-water injection mandrel, i-safty joint, i-telescope, i-downhole choke, i-hydraulic jetting joint, i-screened joint.
