Yintoni iPAC kulwelo lokomba?

Kwi-drilling fluids, i-PAC ibhekiselele kwi-polyanionic cellulose, eyona nto ibalulekileyo esetyenziselwa ukugrumba ukwakhiwa kodaka.Ukugrumba udaka, okwakwaziwa njengolwelo lokugrumba, kudlala indima ebalulekileyo kwinkqubo yokomba yeoli nerhasi.Isebenza ngeenjongo ezahlukeneyo, ezifana nokupholisa kunye nokuthambisa i-drill bits, ukuthutha ukusika phezulu, ukubonelela ukuzinza kwe-wellbore, kunye nokulawula uxinzelelo lokubumba.

I-Polyanionic cellulose i-polymer e-soluble yamanzi ephuma kwi-cellulose, i-polymer yendalo efumaneka kwizityalo.I-PAC yongezwa kwi-drilling fluids ukuphucula i-rheology yabo kunye neempawu zokulawula ukuhluza.

1. Ubume beMichiza kunye neempawu ze-polyanionic cellulose (PAC):

I-PAC i-polymer ye-cellulose eguqulwayo kunye ne-anionic charge.
Ubume bayo beekhemikhali zenza ukuba kube lula ukunyibilika emanzini, ukwenza isisombululo esizinzileyo.
Ubume be-anionic bePAC bunegalelo kwisakhono sayo sokusebenzisana namanye amacandelo kulwelo lokomba.

2. Iimpawu eziphuculweyo zerheological:

I-PAC isetyenziselwa ukuguqula iimpawu ze-rheological ze-drilling fluids.
Ichaphazela i-viscosity, amandla e-gel kunye nokulawula ukulahlekelwa kwamanzi.
Ukulawula i-rheology kubalulekile ekuphuculeni ukuthuthwa kokusika kunye nokugcina uzinzo lwe-wellbore.

3. Ulawulo lwesihluzi:

Omnye wemisebenzi ephambili yePAC kukulawula ukulahleka kolwelo ngexesha lomsebenzi wokomba.
Yenza ikhekhe lokucoca elicekethekileyo, elingangenekiyo kwiindonga zomthombo, ukuthintela ukulahleka kolwelo lokomba ekubunjweni.
Oku kunceda ukugcina iipropati ezifunwayo zodaka lokugaya kunye nokuthintela umonakalo wokwakheka.

4. Uzinzo lwe-Wellbore:

I-PAC inegalelo kuzinzo lwe-wellbore ngokunqanda ulwelo olugqithisileyo ukuba lungangeni kulwakhiwo.
Inceda ukucutha umahluko obambekayo kunye nezinye iingxaki ezinxulumene nokungazinzi kwe-wellbore.
Uzinzo lweWellbore lubalulekile kwimpumelelo yemisebenzi yokomba.

5. Iindidi zePAC kunye nezicelo zazo:

Amabanga ahlukeneyo ePAC ayafumaneka ngokuxhomekeke kubunzima bemolekyuli kunye neqondo lokutshintshwa.
PACs viscosity High zisetyenziswa ngokuqhelekileyo apho kufuneka ulawulo rheology eliphezulu.
Kwizicelo apho ulawulo lokulahleka kolwelo luyinkxalabo ephambili, iPAC ye-viscosity ephantsi inokukhethwa.

6. Iingqwalasela zokusingqongileyo:

I-PAC isoloko ithathwa njengenobuhlobo nendalo esingqongileyo kuba iyabola.
Uvavanyo lwempembelelo yokusingqongileyo lwenziwa ukuze kuqinisekiswe usetyenziso olunenkathalo kunye nokulahlwa kolwelo lokomba oluqulathe iPAC.

7. Ulawulo lomgangatho kunye novavanyo:

Kuphunyezwe amanyathelo angqongqo olawulo lomgangatho ukuqinisekisa ukusebenza kakuhle kwePAC kulwelo lokomba.
Iimvavanyo ezahlukeneyo, kubandakanywa imilinganiselo ye-rheological kunye neemvavanyo zelahleko yolwelo, zenziwa ukuvavanya ukusebenza kwe-PAC-equlethe udaka lokomba.

8. Imingeni kunye nezinto ezintsha:

Ngaphandle kokusetyenziswa kwayo ngokubanzi, imingeni efana nokuzinza kwe-thermal kunye nokuhambelana nezinye izongezo zinokuvela.
Uphando oluqhubekayo kunye nokuqaliswa kwezinto ezintsha zinikezelwe ekusombululeni le mingeni kunye nokuphucula ukusebenza ngokubanzi kwePAC kulwelo lokomba.

I-Polyanionic cellulose (i-PAC) yinxalenye ebalulekileyo yokwakhiwa kwe-drilling fluid kwaye igalelo ekulawuleni i-rheology, ulawulo lokucoca kunye nokuzinza kwe-wellbore.Iimpawu zayo ezikhethekileyo zenza ukuba ibe yinto ebalulekileyo yokongeza kwi-oyile kunye ne-gas drilling industry, idlala indima ephambili kwimpumelelo kunye nokusebenza kakuhle kwemisebenzi yokugaya.
