I-Humic acid yohlobo lolwelo lodibaniso lokulahleka kolwelo luhlobo lwe-polymer yeoli ye-samente yelahleko yolwelo isongezo esiye safumana ukuthandwa kwiminyaka yakutshanje.Njengenye yeemveliso ezintsha ze-Oilbayer, inkampani ekhethekileyo kwi-R&D kunye nokuveliswa kweekhemikhali ze-oilfield, esi songezo selahleko yolwelo siyilelwe ukunceda abaqhubi be-oyile kunye negesi kukhangelo lwemveliso ephezulu kunye nokusebenza kakuhle.
Olu hlobo lwezongezelelo luqhele ukwenziwa ngokudityaniswa kwe-AMPS/NN/humic acid enobushushu obulungileyo kunye nokumelana netyuwa.I-asidi ye-humic isebenza njenge-monomer ephambili, ngelixa ezinye ii-monomers ezixhathisa ityuwa zidityanisiwe ukunyusa ukusebenza kwayo.Isiphumo sisidibaniso esisebenza kakhulu esinokunceda ukunciphisa ilahleko yolwelo ngexesha lokufakwa kwesamente kakuhle, ngaloo ndlela kunyuswa ukusebenza kwequla nokuphucula imbuyekezo iyonke kutyalo-mali.
Ukulahleka kolwelo yingxaki eqhelekileyo kwishishini leoli kunye negesi, ngakumbi ngexesha lemisebenzi yesamente.Kwenzeka xa ulwelo olusetyenziselwa isamente kwiqula lungena etyeni, lushiya izithuba ezinciphisa amandla ebhondi yesamente.Oku kunokukhokelela kwinani lemiba, efana nokuncitshiswa kwemveliso, ukonyuka kweendleko zokuyilungisa, kwaneengxaki zengqibelelo.
I-Humic acid yodidi lolwelo isongezo sokulahlekelwa kunceda ukunciphisa ezi ngxaki ngokwenza umaleko okhuselayo ojikeleze umthombo.Olu luhlu lusebenza njengesithintelo, luthintela ulwelo lwe-samente ukuba lungene ekubunjweni kunye nokunciphisa inani le-fluid elahlekileyo ngexesha lemisebenzi ye-cementing.Oku kuphunyezwa ngokudityaniswa kweempawu ezizodwa zepolymer, ezinceda ukunyusa i-viscosity ye-cement fluid kunye nokuthintela ukuba ingaphumi kumthombo.
Enye yeenzuzo eziphambili zokusebenzisa i-humic acid yohlobo lwezongezo zelahleko zolwelo lubushushu obugqwesileyo kunye nokumelana netyuwa.Oku kuthetha ukuba zinokusetyenziswa kwiindawo ezininzi ezingqongileyo, kubandakanywa ukubunjwa kobushushu obuphezulu kunye nezo zinetyuwa eninzi.Oku kuguquguquka kubenza babe lolona khetho lufanelekileyo kubasebenzisi be-oyile kunye negesi abajonge ukwandisa ukusebenza kakuhle kunye nemveliso yemisebenzi yabo yokomba.
Ukuqukumbela, uhlobo lwe-asidi ye-humic yohlobo lokulahleka kolwelo isongezo sisisombululo esitsha kwiingxaki zokulahleka kolwelo ezifunyanwa lishishini leoli kunye negesi.Iphuhliswe yi-Oilbayer, le mveliso idibanisa inzuzo ekhethekileyo ye-AMPS / NN / i-humic acid kunye nezinye i-monomers ezichasene netyuwa ukuze zenze i-additive esebenzayo kakhulu enokusetyenziswa kwizicelo ezininzi.Ukuba unomdla ekuphuculeni imveliso kunye nokusebenza kakuhle kwemisebenzi yakho yokomba, cinga ngokubandakanya i-humic acid yodidi lwelahleko yolwelo isongezo kwimisebenzi yakho yokwenza isamente.
PHAKATHI KUNYE NOLOLUDWE OKUPHANTSI I-POLYMER FLUID SIDUCER
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.
