Iipropati ze-polyacrylamide ye-industrial ye-thickening, i-flocculation kunye nolawulo lwe-rheological lwe-fluid yenza ukuba idlale indima ebalulekileyo kwimveliso yeoli.Isetyenziswa kakhulu ekwembeni, ukuplaga amanzi, amanzi aneasidi, ukuqhekeka, ukuhlamba kakuhle, ukugqibezela kakuhle, ukunciphisa ukutsala, ukuchasana nokufuduswa kweoli.
Ngokubanzi, ukusetyenziswa kwe-polyacrylamide kukuphucula izinga lokubuyisela ioli.Ngokukodwa, iindawo ezininzi ze-oyile ziye zangena kwimveliso yesibini kunye neyesithathu, ubunzulu bedama ngokuqhelekileyo bungaphezulu kwe-1000m, kwaye enye inzulu ye-reservoir ifikelela kwi-7000m.Ukwahluka kokwenziwa kunye namasimi e-oyile ekude nonxweme kubeke phambili iimeko ezingqongqo ngakumbi kwimisebenzi yokubuyisela i-oyile.
Phakathi kwabo, imveliso yeoli enzulu kunye nemveliso yeoli engaselunxwemeni ngokuhambelana nayo ibeka phambili iimfuno ezintsha zePAM, ezifuna ukuba zixhathise ukucheba, ubushushu obuphezulu (ngaphezu kwe-100 ° C ukuya kuma-200 ° C), i-calcium ion, ukumelana ne-magnesium ion, ukuxhathisa ukuthotywa kwamanzi olwandle, ukususela ngo-1980, kuye kwenziwa inkqubela enkulu kuphando olusisiseko, ukulungiswa, uphando lwesicelo kunye nophuhliso oluhlukeneyo lwe-PAM olulungele ukubuyiswa kweoli kwamanye amazwe.
I-polyacrylamide ye-industrial isetyenziswa njenge-addilling fluid kunye ne-fracturing fluid additive:
Inxalenye ye-hydrolyzed polyacrylamide (HPAM), ephuma kwi-hydrolysis ye-polyacrylamide, isoloko isetyenziswa njenge-modifier yokwemba ulwelo.Indima yalo kukulawula i-rheology yolwelo lokomba, ukuthwala ukusika, ukuthambisa i-drill bit, ukunciphisa ilahleko yolwelo, njl njl. Ulwelo lokomba olumodyuliweyo nge-polyacrylamide lunobunzima obuthile obuphantsi, obunokunciphisa uxinzelelo kunye nokuvaleka kwi-oyile kunye ne-gas reservoir, kulula ukufumana i-oyile kunye ne-gas reservoir, kwaye ilungele ukugrumba, isantya sokomba siphezulu nge-19% kunolwelo oluqhelekileyo lokomba, kwaye malunga ne-45% ephezulu kunesantya sokomba oomatshini.
Ukongeza, inokunciphisa kakhulu iingozi zokugrumba, ukunciphisa ukunxiba kwezixhobo, kwaye kuthintele ilahleko kunye nokuwa.Itekhnoloji yefracturing linyathelo elibalulekileyo lokuvuselela ukuphuhlisa iibhedi ezixineneyo kwiindawo zeoyile.I-Polyacrylamide crosslinked fracturing fluid isetyenziswa ngokubanzi ngenxa ye-viscosity yayo ephezulu, ukukhuhlana okuphantsi, umthamo wesanti emisiweyo, ukuhluzwa okuncinci, ukuzinza okuhle kwe-viscosity, intsalela encinci, ukubonelela ngokubanzi, ukulungiswa okufanelekileyo kunye neendleko eziphantsi.
Kwi-fracturing kunye nonyango lwe-asidi, i-polyacrylamide ilungiswa kwisisombululo esinamanzi kunye noxinaniso lwe-0.01% ukuya kwi-4% kunye nokumpontshelwa kwi-formation ephantsi komhlaba ukuphuka ukubunjwa.Isisombululo sepolyacrylamide yezoshishino sinomsebenzi wokujiya kunye nokuthwala isanti kunye nokunciphisa ilahleko ye-fracturing fluid.Ukongeza, i-polyacrylamide inefuthe lokunciphisa ukuxhathisa, ukwenzela ukuba ilahleko yokudlulisa uxinzelelo ingancitshiswa.
