Mabhobhu egirazi seDensity Reducation Agent muOil Base Drilling Fluid for MarginalLow-Permeability Low Pressure Reservoirs
Hollow glass spheres, inozivikanwawo semagirazi mabhubhu, sechinhu chinoderedza density mumvura yekuchera. Mukushandiswa kwemumunda, mafuta emumvura-mumvura emulsion fluid yaive negoro regirazi yakashandiswa yakashandiswa panguva yekuchera yenguva yekuburitsa. Emulsion yemafuta-mu-mvura yakapa chigadziko chakakodzera chemvura, nepo mabhurabhu egirazi, nekuda kwekuderera kwawo, akapa yakaderera kupera density kupfuura iyo inowirirana base fluid. Density inodzikisira kugona kwemagirazi mabubbles inoenzana nekusangana kwemabhuru akaiswa mumvura.
Mukushandiswa kwemunda, iyo fluid-girazi bubble pair yakagadzikana, ine homogenous, uye inoenderana kuburikidza neyakajairwa madhaka mota, mabits, pamusoro pekuchenesa midziyo, uye yeakadaro rheological uye filtrate zvivakwa, sekuzvikweretesa kuti ishandiswe mune yakaderera madhirigi uye mukati. kugadzira nzvimbo dzepamusoro permeability.
Girazi mabheji spherical chimiro, chine kuomarara kwepamusoro, kutsetseka kwepamusoro, senge maficha, kuita kwekukunguruka kwakanaka. Ishandise sekuwedzera kwemvura yekuchera, inogona kuita basa rakafanana nekutakura mubhora, kuderedza zvakanyanya kupikisa kwepombi yekuchera, mvura yekuchera, kukurumidza kuchera, kunatsiridza mwero wekupinda, uye kuderedza kupera kwebhiti.
Iye zvino, mukuongorora nekusimudzira kwakaoma, chinangwa chepamusoro pasi pemamiriro ekuvigwa kwakadzika, kuderera kwekugadzirisa kudzvinyirira nekushandiswa kwegirazi mabheji mukuchera pasi pasi kune zvakanakira zvakawanda, chimwe chezvakanakira magirazi mabheji anogona kuvandudza kumhanya kwekuchera; Kubva pashaft kusvika kune yekusiyanisa fluid kudzvinyirirwa kwekuumbwa kwemvura muhuwandu hwe0 ~ 6.9 Mpa, iyo yakajairika nzira yekuchera mujecha, limestone, shale yekudhiraivha zvakanaka yaizodzikisa 70 ~ 80%, uye magirazi mabheji anogona kuderedza kudzvanywa kwegomba zvakanyanya kunatsiridza kuchera. kunyatsoshanda.
Xingtai Kehui Trading Co., Ltd. izere-kambani inobatanidza kugadzira, kutengesa, uye kutenga. Iyo kambani uye fekitori iri muXingtai City, Hebei Province, ine nhoroondo refu uye yakapfuma muzvicherwa. Parizvino, zvigadzirwa zvekambani zvinosanganisira nhunzi madota, cenospheres, perlite, hollow girazi microsphere, macro synthetic fiber nezvimwewo, kushandiswa kwezvigadzirwa zvakagadzirirwa kuramba zvimisikidzo zvekudzivirira, zvekuvakisa, indasitiri yepetroleum, indasitiri yekuvhara, indasitiri yekuputira, ndege uye nzvimbo. kusimudzira, indasitiri yepurasitiki, girazi faibha yakasimbisa zvigadzirwa zvepurasitiki uye zvekurongedza zvinhu.
Tine makore makumi maviri nemasere ruzivo rwekugadzira refractories uye zvinopisa zvekudzimisa zvinhu, isu tinosimbirira pakupa yakakwirira-preformanced refractories uye mhando yemafuta ekudzivirira zvinhu, takagadzirawo zvimwe zvakawanda zvemhando zvigadzirwa senge macro synthetic fiber,
mvura-inoderedza musanganiswa, tiri kuita zvatinokwanisa kuti tigutse zvakasiyana zvinodiwa nemutengi.
Tinovimba kuenderera mberi nekuperekedza vatengi vedu nezvigadzirwa zvemhando yepamusoro uye mabasa ehunyanzvi! Chero bedzi mutengi achida, tiri pano chero nguva!
