Yintoni ukusetyenziswa kwe-cellulose ekubholeni udaka

I-Cellulose, i-carbohydrate entsonkothileyo efumaneka eludongeni lweeseli zezityalo, idlala indima ebalulekileyo kumashishini ahlukeneyo, kuquka icandelo leoyile negesi. Kwindawo yokumba udaka, i-cellulose isebenza ngeenjongo ezahlukeneyo ngenxa yeempawu zayo ezikhethekileyo kunye neempawu zayo.

Ukugrumba udaka, okwaziwa ngokuba lulwelo lokugrumba, yinxalenye ebalulekileyo kwinkqubo yokugrumba imigodi yeoyile negesi. Isebenza imisebenzi emininzi ebalulekileyo, kuquka ukupholisa nokuthambisa i-drill bit, ukuthwala iziqwenga zamatye kumphezulu, ukugcina uzinzo lwe-wellbore, kunye nokuthintela umonakalo wokwakheka. Ukuze kufezekiswe le misebenzi ngempumelelo, ukugrumba udaka kufuneka lube neempawu ezithile ezifana ne-viscosity, ulawulo lokulahleka kolwelo, ukumiswa kwezinto eziqinileyo, kunye nokuhambelana neemeko zomngxuma ongaphantsi.

I-CelluloseIsetyenziswa kakhulu kwiifomyula zodaka lokubhola njengesongezelelo esiphambili ngenxa yeempawu zalo ezibalaseleyo ze-rheological kunye nokuguquguquka. Omnye wemisebenzi ephambili ye-cellulose kudaka lokubhola kukubonelela nge-viscosity kunye nolawulo lwe-rheological. I-viscosity yindlela yokulinganisa ukumelana kolwelo nokuhamba kwamanzi, kwaye ibalulekile ekugcineni iimpawu zokuhamba ezifunekayo zodaka lokubhola. Ngokongeza i-cellulose, i-viscosity yodaka ingalungiswa ukuze ihlangabezane neemfuno ezithile zomsebenzi wokubhola. Oku kubaluleke kakhulu ekulawuleni izinga lokungena, ukuthintela ukulahleka kolwelo ekwakhekeni, kunye nokuthwala iziqwenga zokubhola kumphezulu.

I-cellulose isebenza njenge-viscosifier kunye ne-arhente yokulawula ukulahleka kolwelo ngaxeshanye. Njenge-viscosifier, inceda ukumisa nokuthutha iziqwenga zokubhola ziye kumphezulu, ithintela ukuba zingahlali kwaye ziqokelelene ezantsi kwe-wellbor. Oku kuqinisekisa ukusebenza kakuhle kokubhola kwaye kunciphisa umngcipheko weziganeko zokunamathela kwepayipi. Ukongeza, i-cellulose yenza ikhekhe lesihluzo elincinci, elingangeni manzi eludongeni lwe-wellbor, elinceda ukulawula ukulahleka kolwelo ekubunjweni. Oku kubalulekile ekugcineni uzinzo lwe-wellbor kunye nokuthintela umonakalo wokwakheka okubangelwa kukungena kolwelo.

Ukongeza kwiipropati zayo zokulawula ukulahleka kwe-rheological kunye nolwelo, i-cellulose ikwabonelela ngeenzuzo zokusingqongileyo kwi-drilling mud formulations. Ngokungafaniyo nezongezo ezenziweyo, i-cellulose iyabola kwaye inobuhlobo nokusingqongileyo, nto leyo eyenza ukuba ibe lukhetho olukhethwayo kwimisebenzi yokubhola enobuthathaka kokusingqongileyo. Ukubola kwayo kuqinisekisa ukuba iyabola ngokwendalo ngokuhamba kwexesha, kunciphisa impembelelo yemisebenzi yokubhola kokusingqongileyo.

I-Cellulose ingafakwa kwiifomyula zodaka zokubhola ngeendlela ezahlukeneyo, kubandakanya i-cellulose ephuhliweyo, iifayibha ze-cellulose, kunye nezinto eziphuma kwi-cellulose ezifanai-carboxymethyl cellulose (CMC)kwayei-hydroxyethyl cellulose (HEC)Uhlobo ngalunye lubonelela ngeenzuzo ezithile kunye nemisebenzi ngokuxhomekeke kwiimfuno zomsebenzi wokugrumba.

I-cellulose egutyiweyo isetyenziswa kakhulu njenge-viscosifier ephambili kunye ne-arhente yokulawula ukulahleka kolwelo kwiinkqubo zodaka ezisekelwe emanzini. Isasazeka lula emanzini kwaye ineempawu ezintle zokuxhoma, nto leyo eyenza ukuba ilungele ukuthwala iziqwenga zokubhola ngaphezulu.

Kwelinye icala, iifayibha ze-cellulose zinde kwaye zine-fibrous kune-cellulose ecoliweyo. Zihlala zisetyenziswa kwiinkqubo zodaka ezixinyiweyo, apho kufuneka khona ulwelo lokugrumba oluxineneyo ukulawula uxinzelelo lokwakheka. Iifayibha ze-cellulose zinceda ukuphucula ukuqina kwesakhiwo sodaka, ukuphucula ukusebenza kakuhle kokucoca imingxunya, kunye nokunciphisa i-torque kunye nokutsala ngexesha lomsebenzi wokugrumba.

Izinto eziphuma kwi-cellulose ezifanaI-CMCkwayeI-HECziintlobo ze-cellulose eziguqulwe ngokweekhemikhali ezibonelela ngeempawu zokusebenza eziphuculweyo. Zihlala zisetyenziswa kwizicelo ezikhethekileyo zodaka lokubhola apho kufuneka kuhlangatyezwane neemfuno ezithile zokusebenza. Umzekelo, i-CMC isetyenziswa kakhulu njenge-shale inhibitor kunye ne-fluid loss loss agent kwiinkqubo zodaka ezisekelwe emanzini, ngelixa i-HEC isetyenziswa njenge-rheology modifier kunye ne-filtration agent kwiinkqubo zodaka ezisekelwe kwioyile.

I-cellulose idlala indima ebalulekileyo ekubumbeni udaka ngenxa yeempawu zayo ezizodwa kunye nokuguquguquka kwayo. Ukususela ekuboneleleni nge-viscosity kunye nolawulo lwe-rheological ukuya ekuphuculeni ulawulo lokulahleka kolwelo kunye nokuzinza kokusingqongileyo, i-cellulose inika iingenelo ezininzi kwimisebenzi yokumba. Njengoko ishishini leoyile negesi liqhubeka nokukhula, kulindeleke ukuba imfuno yezisombululo zodaka zokumba ezisebenzayo nezinobuhlobo nokusingqongileyo inyuke, nto leyo egxininisa ngakumbi ukubaluleka kwe-cellulose njengesithako esibalulekileyo kwifomyula yolwelo lokumba.
