Yazisa:
Itekhnoloji ye-oyile ye-polymer ye-cementing isetyenziswe ngokubanzi kuphononongo kunye nophuhliso lwamasimi e-oyile kunye negesi.Enye yezinto ezibalulekileyo kwi-teknoloji ye-polymer cementing yi-arhente yokulwa nokulahlekelwa kwamanzi, enokunciphisa izinga lokulahlekelwa kwamanzi ngexesha lenkqubo yokumisa.Ukusetyenziswa kwetekhnoloji yesamente yepolymer kuneengenelo ezininzi ezinje ngokuqina okuphezulu, ukungeneka okuphantsi, kunye nokusebenza okugqwesileyo kokutywinwa.Nangona kunjalo, ingxaki eqhelekileyo edibana nayo kule nkqubo kukulahlekelwa kwamanzi, oko kukuthi, i-sement slurry ingena ekubunjweni, okwenza kube nzima ukukhupha ityhubhu ngexesha lokubuyisela ioli.Ke ngoko, uphuhliso lweqondo eliphakathi kunye nelisezantsi lokulahleka kolwelo lokunciphisa ubushushu sele kugxilwe kwi-oilfield cementing technology progress.
Isinciphisi selahleko yeoli yePolymer kakuhle:
I-Fluid loss additive sisixhobo esiyimfuneko sokulungiselela udaka lwesamente.Ingumgubo onyibilikayo ngokulula emanzini kwaye uneempawu ezilungileyo zokuxuba.Ngethuba lokuqulunqwa, ii-agent zokulawula ukulahleka kwamanzi zixutywe kunye namanye amacandelo ukuze zenze i-slurry ye-samente ene-homogeneous kunye ne-stable slurry.I-arhente yokulawula ukulahleka kwamanzi idlala indima ebalulekileyo ekunciphiseni izinga lokulahlekelwa kwamanzi ngexesha lenkqubo yokumisa.Iyanciphisa ukufuduka kwamanzi odakeni ukuya kwiifom ezijikelezileyo kunye nokuphucula iimpawu zomatshini zesamente.
Ilahleko yamanzi ≤ 50:
Xa usebenzisa ii-agent zokunciphisa ukulahleka kwamanzi, kubalulekile ukulawula izinga lokulahlekelwa kwamanzi ngaphakathi kwinqanaba elithile, ngokuqhelekileyo lingaphantsi okanye lilingana ne-50ml / 30min.Ukuba umlinganiselo wokulahleka kwamanzi uphezulu kakhulu, udaka lwesamente luya kungena ekubunjweni, lubangele umjelo wokutsala amanzi, udaka, kunye nokusilela kwesamente.Ngakolunye uhlangothi, ukuba izinga lokulahlekelwa kwamanzi liphantsi kakhulu, ixesha le-cementing liya kwandiswa, kwaye i-agent eyongezelelweyo yokulwa nokulahlekelwa kwamanzi iyadingeka, eyandisa iindleko zenkqubo.
Isinciphisi sokuphulukana nolwelo oluphakathi noluphantsi:
Ngexesha lenkqubo yesamente kwiindawo zeoli, izinga lokulahlekelwa kwamanzi lichatshazelwa zizinto ezahlukeneyo ezifana nobushushu bokwakheka, uxinzelelo, kunye nokungena kwamanzi.Ngokukodwa, iqondo lokushisa le-cementing fluid linempembelelo ebalulekileyo kwizinga lokulahlekelwa kwamanzi.Ilahleko yolwelo idla ngokunyuka kakhulu kumaqondo obushushu aphezulu.Ngoko ke, kwinkqubo yokumisa i-cementing, kuyimfuneko ukusebenzisa izongezo zokulahlekelwa kwamanzi aphakathi kunye nezantsi ezinokunciphisa izinga lokulahlekelwa kwamanzi kumaqondo aphezulu.
Isishwankathelo:
Ngamafutshane, itekhnoloji ye-oyile ye-polymer yesamente iye yaba yenye yetekhnoloji ebalulekileyo yokuhlola intsimi ye-oyile kunye nerhasi.Enye yezinto eziphambili zeteknoloji yi-arhente echasene nokulahlekelwa kwamanzi, edlala indima ebalulekileyo ekunciphiseni izinga lokulahlekelwa kwamanzi ngexesha lenkqubo yokumisa.Ukulawulwa kokulahleka kwamanzi ngexesha lokulungiswa kodaka nako kudlala indima ebalulekileyo ekuqinisekiseni impumelelo yenkqubo yokufakwa kwesamente.Ukuphuhliswa kwezinciphisi zokulahlekelwa kwamanzi obushushu aphakathi naphantsi kubaluleke kakhulu ekuphuculeni ukusebenza kwesamente, ukunciphisa iindleko kunye nokuphucula imfezeko yemithombo yeoli nerhasi.
