Girazi reChina rinotengeswa nevatengi - Mabhurumu eGirazi seMushonga wekuderedza Density muOiri Base Drilling Fluid yeMarginalLow-Permeability Low Pressure Reservoirs – Kehui

Magirazi madiki, anozivikanwawo semagirazi madiki, sechinhu chinodzikisa huwandu hwemvura mumvura inoboorwa. Mukushandiswa kwemumunda, mvura yemafuta mumvura ine magirazi madiki yakashandiswa panguva yekuboorwa kwechikamu chekugadzira. Emulsion yemafuta mumvura yakapa hwaro hwakakodzera hwemvura, nepo magirazi, nekuda kwehuwandu hwawo hwakaderera, akapa huwandu hwakaderera hwakapedzwa pane hwemvura yebase inoenderana. Kugona kuderedza huwandu hwemagirazi madiki kwakaenzana nehuwandu hwemabubbles ari mumvura.

Mukushandiswa kwemumunda, girazi rine mabubble rakagadzikana, rakafanana, uye rinoenderana nemagetsi ekare, mabhiti, michina yekuchenesa pamusoro, uye ine hunhu hwakadai hwe rheological uye filtrate, zvekuti inogona kushandiswa munzvimbo dzine pressure shoma uye mukugadzira nzvimbo dzine mvura yakawanda.
Magadzirirwo egirazi ebhora, ane kuomarara kwakanyanya, pamusoro wakatsetseka, senge zvinhu, mashandiro ekutenderera akanaka. Rishandise sekuwedzera kwemvura yekuboorera, rinogona kuita basa rakafanana nebheyaringi riri mubhora, rinoderedza zvakanyanya kupokana kwepombi yekuboorera, mvura yekuboorera, kuchera nekukurumidza, kuvandudza mwero wekupinda, uye kuderedza kupera kwezvidimbu.
Zvino, mukutsvaga nekuvandudza kwakaoma, chinangwa chakaiswa pasi pemamiriro ekudzika kwakavigwa, kumanikidzwa kwakaderera kwekugadzirwa nekushandisa magirazi egirazi mukuchera kusina kuenzana kune zvakanakira zvakawanda, chimwe chezvakanakira zvikuru ndechekuti magirazi egirazi anogona kuvandudza kumhanya kwekuchera; Kubva pamugodhi kusvika pakumanikidzwa kwemvura yakasiyana-siyana yekugadzirwa kwemvura iri pakati pe0 ~ 6.9 Mpa, nzira yakajairika yekuchera mujecha, limestone, shale drilling efficiency yaizodzikira ne70 ~ 80%, uye magirazi egirazi anogona kuderedza kumanikidzwa kwemvura zvakanaka uye zvakanyanya kuvandudza kushanda kwekuchera.

邢台科汇商贸有限公司 ikambani yakazara inobatanidza kugadzirwa, kutengeswa, uye kutenga. Kambani iyi nefekitori zviri muXingtai City, Hebei Province, ine nhoroondo refu uye yakapfuma muzvicherwa. Parizvino, zvigadzirwa zvekambani zvinosanganisira fly ash, cenospheres, perlite, hollow glass microsphere, macro synthetic fiber nezvimwewo, kushandiswa kwezvigadzirwa izvi kwakagadzirirwa zvinhu zvinodzivirira kupisa, zvinhu zvekuvaka, indasitiri yepetroleum, zvinhu zvinodzivirira kupisa, indasitiri yekuputira, indasitiri yendege nekugadzira nzvimbo, indasitiri yepurasitiki, zvigadzirwa zvepurasitiki zvinosimbisa fiber yegirazi nezvinhu zvekurongedza.
Tine ruzivo rwemakore makumi maviri nemasere mukugadzira zvinhu zvinodzivirira kupisa (refractories) uye zvinodzivirira kupisa (thermal insulation), tinosimbirira pakupa zvinhu zvinodzivirira kupisa (thermal insulation) zvakagadzirwa zvakanaka uye zvinhu zvemhando yepamusoro zvinodzivirira kupisa (thermal insulation), takagadzirawo zvimwe zvigadzirwa zvemhando yepamusoro zvakaita sema macro synthetic fiber,
Musanganiswa unoderedza mvura, tiri kuita zvese zvatinogona kuti tigutse zvinodiwa nevatengi vakasiyana.
Tinovimba kuti ticharamba tichiperekedza vatengi vedu nezvigadzirwa zvemhando yepamusoro uye mabasa ehunyanzvi! Chero bedzi mutengi achida, tiripo chero nguva!
