I-Hydroxy Ethyl Cellulose (HEC) - i-oildrilling

I-Hydroxyethyl cellulose (HEC) i-polymer e-soluble yamanzi ephuma kwi-cellulose, esetyenziswa ngokubanzi njenge-rheology modifier kunye ne-arhente yokulawula ukulahlekelwa kwamanzi kwimisebenzi yokugaya ioli.

Ngexesha lokugaya i-oyile, ulwelo lokomba lusetyenziselwa ukuthambisa i-drill bit, ukuthwala i-drill cuttings ukuya phezulu, kunye nokulawula uxinzelelo equleni.Ulwelo lokomba lukwanceda ukuzinzisa umthombo kunye nokuthintela ukonakala kokwakheka.

I-HEC yongezwa kwi-drilling fluids ukwandisa i-viscosity kunye nokulawula iimpawu zokuhamba kwamanzi.Inganceda ukunqumamisa i-drill cuts kunye nokuthintela ukuzinza, ngelixa ikwabonelela ngolawulo olulungileyo lwelahleko yolwelo ukugcina ingqibelelo yequla.I-HEC ingasetyenziselwa njenge-lubricant kunye ne-modifier yekhekhe lokucoca, ukuphucula ukusebenza kakuhle kunye nokusebenza kwenkqubo yokugaya.

Enye yeenzuzo ze-HEC kwi-oyile yokugaya ukuzinza kwayo kwiqondo lokushisa eliphezulu kunye neemeko eziphezulu zoxinzelelo.I-HEC inokugcina iipropati zayo ze-rheological kunye nokusebenza kokulawulwa kokulahlekelwa kwamanzi kuluhlu lwamaqondo obushushu kunye noxinzelelo, okwenza ukuba ilungele ukusetyenziswa kwiindawo ezicela umngeni.

I-HEC iphinda ihambelane nezinye izinto ezisetyenziselwa ukugaya amanzi, njengodongwe, iipolymers, kunye neetyuwa, kwaye zinokufakwa ngokulula ekuqulunqweni.Ubutyhefu bayo obuphantsi kunye nokubola kwayo kuyenza ikhuseleke ngokusingqongileyo kwaye ikhuseleke ukuba isetyenziswe kwimisebenzi yokomba ioyile.

Ngokubanzi, i-HEC yipolymer eguquguqukayo enokubonelela ngolawulo olusebenzayo lwe-rheological kunye nokulawulwa kwelahleko yolwelo kulwelo lokomba ioyile.Iimpawu zayo ezikhethekileyo kunye nokuhambelana nezinye izinto zenza ukuba kube yinto edumileyo kwimisebenzi yokugaya kwiindawo ezahlukeneyo.
