Ukuqonda indima yezixhobo zokutofa ngemichiza kwiimveliso zokulawula kakuhle
Ukusetyenziswa kweizixhobo zokutofa ngemichizaibaluleke kakhulu ekugcineni imfezeko kunye nokusebenza kakuhle kwemithombo yeoli nerhasi. Ezi zixhobo zidlala indima ebalulekileyo ekuqinisekiseni uzinzo kunye nemveliso ngokuzisa imichiza eyahlukeneyo emngxunyeni. Kodwa zikwenza njani kanye eziizixhobo zokutofa ngemichizaumsebenzi, kwaye yintoni ukubaluleka kwabo kwiimveliso zolawulo kakuhle?
Iiyunithi zokutofa ngemichiza ziyilelwe ukuhambisa iikhemikhali ezithile, ezifana ne-corrosion inhibitors, i-scale inhibitors, i-biocides kunye ne-demulsifiers, kumthombo womthombo ukujongana nemiba eyahlukeneyo enokuthi ivele ngexesha lenkqubo yokuvelisa. Ezi zixhobo ziyinxalenye ebalulekileyo yeemveliso zokulawula kakuhle kuba zinceda ukuthintela nokunciphisa iingxaki ezinokubakho ezinokulimaza ukusebenza kakuhle kunye nokuphila ixesha elide.
Ukusebenza kweyunithi yokutofa kweekhemikhali kuqala ngokukhethwa kunye nokulungiswa kwesisombululo sekhemikhali esifanelekileyo. Nje ukuba isisombululo sekhemikhali silungile, simpontshelwa kwiyunithi yokutofa, ehlala ibekwe kumphezulu okanye kumngxuma osezantsi, kuxhomekeke kulungiselelo oluthile lomthombo kunye neemfuno.
Iiyunithi zokutofa ngemichiza engaphezulu zidla ngokusetyenziswa kumaqula afikeleleka lula ukuze kube lula ukubeka iliso nokugcinwa kwawo. Ezi zixhobo zixhotyiswe ngeepompo kunye neenkqubo zokulawula ezilawula ukuhamba kunye noxinzelelo lwezisombululo zamakhemikhali njengoko zifakwe kwi-wellbore. Iiyunithi ze-Downhole chemical injection units, kwelinye icala, zifakwe kumaqula angenako ukufikelela okulinganiselweyo kwaye zenzelwe ukujamelana neemeko ezinzima zemingxuma ngelixa zihambisa ngokufanelekileyo iikhemikhali kwiindawo ezijoliswe kuzo.
Inkqubo yokutofa ilawulwa ngononophelo ukuqinisekisa ukuba iikhemikhali zilungelelaniswa kwaye zisasazwa ngokufanelekileyo kuwo wonke umthombo. Oku kubalulekile ukujongana nemiba enjengomhlwa, ukukhula, ukukhula kweentsholongwane kunye nokwakhiwa kwe-emulsion, konke oku kunokuchaphazela kakubi iziseko zequla kunye nemveliso.
Enye yeendlela eziphambili ezisetyenziswa kwizixhobo zokutofa iikhemikhali kukusetyenziswa kweempompo ezifanelekileyo zokufuduka, ezikwaziyo ukuhambisa umthamo ochanekileyo weekhemikhali kuxinzelelo olungaguqukiyo. Ezi mpompo zenzelwe ukujongana neentlobo ngeentlobo zeekhemikhali ze-viscosities kunye nokuqamba, okwenza ukuba zilungele iintlobo ezahlukeneyo zezicelo zonyango.
Ukongeza kwiikhemikhali zokutofa, ezinye zihambele phambiliizixhobo zokutofa ngemichizazikwaxhotyiswe ngeenkqubo zokubeka iliso kunye neempendulo ezinokubonelela ngedatha yexesha langempela kwinkqubo yokutofa. Oku kuvumela umqhubi ukuba abeke iliso ngokusondeleyo ukusebenza kwesixhobo sokutofa kwaye enze uhlengahlengiso njengoko lufunekayo ukuze kuphuculwe inkqubo yonyango.
Ukubaluleka kweizixhobo zokutofa ngemichizakwiimveliso zokulawula kakuhle azinakugqithiswa. Ngokuzisa ngokufanelekileyo imichiza kumthombo, ezi zixhobo zinceda ukuthintela kunye nokunciphisa iingxaki ezinokukhokelela ekunciphiseni iindleko, ukusilela kwezixhobo kunye nelahleko yemveliso. Ukongeza, bafaka isandla kwimfezeko yonke kunye nokuphila ixesha elide kwequla, ekugqibeleni baqinisekisa inkqubo yokuvelisa ezinzileyo nesebenzayo.
Isishwankathelo, izixhobo zokutofa kweekhemikhali ziyinxalenye ebalulekileyo yeemveliso zokulawula kakuhle kwaye zidlala indima ebalulekileyo ekugcineni uzinzo kunye nemveliso yeoli kunye negesi yamaqula. Ukuqonda indlela ezi zixhobo zisebenza ngayo kunye nokubaluleka kwazo kwinkqubo yonyango lwequla ngundoqo ekuqinisekiseni ukusebenza kakuhle kunye nobomi obude beziseko zoncedo lwakho.
