I-Welding Semi-Rigid Centralizer

Ama-centralizers ashiselwezingamathuluzi abalulekile embonini ye-petroleum, futhi ikhwalithi yomkhiqizo ibalulekile ekuqinisekiseni impumelelo yokumba kanye nokufaka usimende. Ngokwesiko, ama-centralizers enziwe ngensimbi yekhwalithi ephezulu, ebiza kakhulu. Kodwa-ke, ngokuhlanganiswa okushiselwe okuhlukile kwezinto ezihlukene, senze i-centralizer eqinile enganciphisa kakhulu izindleko zempahla ngenkathi igcina ukusebenza okuhle kakhulu kwekilasi.

Ama-centralizers ashiselweukuthuthukiswa komkhiqizo wethu wakamuva. Yakhelwe ngezici ezishiselwe ezenziwe ngezinto ezihlukahlukene ezihlanganisa insimbi ne-aluminium ukuze kuncishiswe izindleko zempahla ngenkathi kugcinwa ukusebenza. Ukhiqizwe kusetshenziswa amasu okushisela akamuva, lo mkhiqizo uqinisekisa ukuthi zonke izingxenye zilingana ngokunembile futhi zixhumeke ngokuphephile.

Inzuzo enkulu ye-aeshiselwe i-semi-rigid centralizerukuthi isengakwazi ukumelana namandla amakhulu e-radial ngenkathi inekhono lokululama kuma-micro-deformation. Lesi sici sigqamisa ukuqina nokuqina komkhiqizo. Ikhono le-centralizer lokumelana nokuguqulwa kusho ukuthi igcina isimo sayo, iqinisekisa ukuthi ingenza umsebenzi wayo obalulekile ngesikhathi sokumba.

Umkhiqizo unezinhlobonhlobo zezicelo futhi uzifanele kakhulu izimboni ezifana nowoyela negesi lapho imisebenzi yokumba iyinkimbinkimbi kakhulu. Ama-semi-rigid centralizers ayinketho enhle kakhulu yokufaka usimende nokumba imithombo lapho ukuchezuka kokwakheka kuvame. Izici zayo eziyingqayizivele zivumela ukubekwa kwe-casing kalula emgodini we-borehole, okubalulekile ekusebenzeni kukasimende.

Ama-centralizers ashiselweube ne-coefficient ephansi yokungqubuzana ukusiza ukunciphisa ukuhudula ngesikhathi sokuthunyelwa. Ukwengeza, iza nezinhlobonhlobo zobude bomnsalo nezinketho zokumukela amasayizi ahlukahlukene we-casing. Lesi sici sisenza umkhiqizo oguquguqukayo, okuvumela i-centralizer ukuthi ivumelane ngempumelelo kunoma yimuphi usayizi nohlobo lwe-wellbore.

Enye inzuzo ephawulekayo yalo mklamo womkhiqizo ukuthi imelana nokuguga ngemva kokusetshenziswa isikhathi eside. Leli khono libalulekile embonini kawoyela negesi, lapho imisebenzi yokumba ingahlala amasonto noma izinyanga.Ama-centralizers ashiselwezingamelana nezimo zokusebenza ezidlulele futhi zidinga ukunakekelwa okuncane ngesikhathi sokusebenza kwazo.

Ekuphetheni,ezishiselwe semi-rigid centralizersziwumkhiqizo omusha ongazuzisa kakhulu imboni kawoyela. Izindleko ziyancishiswa ngenkathi kugcinwa ukusebenza okungcono kakhulu kwekilasi ngokuhlanganiswa okushiselwe okuhlukile kwezinto ezingafani. Amandla omkhiqizo wokumelana namandla amakhulu e-radial futhi alulame ekulimaleni okuncane, kuhlanganiswe nohlu olubanzi lwezinhlelo zokusebenza, kwenza ama-centralizer abe ithuluzi elibalulekile ekusebenzeni kokumba nokufaka usimende. Ukuguquguquka komkhiqizo futhi kuqinisekisa ukuthi ungafaniswa nanoma yimuphi usayizi nohlobo lomthombo wemithombo. Ekugcineni,ezishiselwe semi-rigid centralizersziyisixazululo esithembekile, esihlala isikhathi eside futhi esingabizi kakhulu sanoma yikuphi ukusebenza komthombo wamanzi.
