1.Ityhubhuukuhlelwa

I-tubing inokwahlulwa ibe yi-tubing (NU), i-tubing ephazamisayo (EU) kunye ne-joint joint tubing.I-Flat ithetha isiphelo sombhobho we-oyile ngaphandle kokuthunga ngokuthe ngqo ukutyeba kwaye uzise amaqhina.Ukuphazamiseka kwetyhubhu kuthetha emva kokuba imibhobho emibini iphelile ngokuphazamiseka kwangaphandle, emva koko kuthungelwe kwaye kuzise ukudityaniswa.Iityhubhu ezidityanisiweyo zizonke zithetha ngomsonto wemoto ophazamiseke ngaphakathi kwelinye icala ngemoto ngaphandle komsonto oshinyeneyo, ngaphandle koqhagamshelo oluthe ngqo.

Indima ye-2.Tubing

① ukukhupha ioyile kunye negesi: ukukhaba ioyile kunye negesi kumthombo wesamente emva koko kufakwe kumbhobho we-oyile wokukhupha i-oyile kunye negesi ngaphezulu.

② amanzi: Xa uxinzelelo lwe-downhole lungonelanga, ngokusebenzisa i-tubing emanzini omthombo.

③ Isitofu somphunga: kwinkqubo yokubuyisela i-oyile enzima, ukusetyenziswa kwetyhubhu egqunyiweyo kwigalelo lomphunga.

④ Ukufakwa kweasidi kunye nokuqhekeka: Kade ekugrumbeni i-oyile kunye nemithombo yerhasi okanye ukuze kuphuculwe isivuno, kuyafuneka ukuba kufakwe i-asidi kwindawo yokugcina amanzi kunye ne-fracturing media okanye ephilisiwe, kwaye iphakathi enyangisiweyo ihanjiswa ngombhobho.
