ERT (Txawm Rubber Thickness):
Tsim nyog los hloov cov duab ntawm stator vaj tse, stator elastomer txheej ntawm Uniform Thickness downhole lub cev muaj zog yog nyias thiab txawm. Cov yam ntxwv ntawm lub downhole lub cev muaj zog yog luv luv, siab zog, siab poob siab, tsis tshua muaj tig ceev, siab txias efficiency, txawm thermal expansion, ntau lug siv, ntau optimized qauv thiab lub sib zog loj. Tshwj xeeb tshaj yog, cov yam ntxwv tuaj yeem ua kom ntev downhole lub cev muaj zog lub neej thiab txhim kho drilling efficiency nyob rau hauv lub ultra-dub zoo, directional zoo thiab kub zoo.
Resistance High-temperature Thiab Oil Based av nkos:
Lub downhole lub cev muaj zog yog tsim rau high-temperature, siab roj puag av nkos system. Nyob rau hauv cov xwm txheej ntawm tsawg dua 180 ° C thiab cov roj siab, tshwj xeeb tsim stator elastomer muaj tus nqi khaws cia siab ntawm lub zog muaj zog, tsim kua muag thiab lwm yam khoom. Cov roj-resistant elastomer nrog qhov tsim nyog loj ntawm kev cuam tshuam tau zoo dua siv cov nyhuv hauv qhov kub-kub, siab roj av av.
Corrosion kuj:
Tom qab corrosion spraying los tsim tshwj xeeb txheej, lub rotor zoo dua corrosion, yaig thiab puas-resistant. Thiab downhole lub cev muaj zog yog haum rau lub sij hawm ntev nyob rau hauv cov kua corrosive.
Cua Drilling:
Huab cua drilling tuaj yeem tiv thaiv lub pas dej kom zoo, txhim kho tus nqi nkag mus, txo qis lub sijhawm drilling, ceev faj tiv thaiv cov av nkos thiab lub qhov dej tawg, tam sim no maj mam siv dav. Cua drilling downhole lub cev muaj zog yog tsav los ntawm cov pa roj, ua npuas ncauj thiab lwm yam compressible kua, muab lub zog rau lub downhole thiab drives me ntsis mus rau hauv pob zeb. Cua drilling downhole lub cev muaj zog muaj kev xav tau ntau dua ntawm cov qauv sib dhos, cov qauv tsim tawm ntawm lub cev muaj zog stator thiab kev ua haujlwm tshwj xeeb.
