Njengoko ingqalelo yehlabathi kukhuseleko lwemekobume iqhubeka isanda, ishishini leoli, njengommandla osisiseko wonikezelo lwamandla, liye latsala ingqalelo engakumbi kwimibandela yalo yemekobume. Kulo mongo, ukusetyenziswa kunye nokulawulwa kweekhemikhali kubaluleke kakhulu.I-Hydroxyethyl Cellulose (HEC), njengesixhobo se-polymer e-soluble ngamanzi, isetyenziswa ngokubanzi kwiinkalo ezininzi ze-oyile ngenxa yokusebenza kwayo okugqwesileyo kunye neempawu zokukhusela okusingqongileyo, ngokukodwa kwi-drilling fluids, i-fracturing fluids kunye ne-stabilizers yodaka.
Iimpawu eziphambili ze-HEC
I-HEC i-polymer engeyiyo ionic eyenziwe ngokuguqula i-cellulose yendalo, eneempawu eziphambili ezilandelayo:
I-Biodegradability: I-KimaCell®HEC yenziwe ngezinto zendalo kwaye inokuchithwa yi-microorganisms, ukuphepha ukuqokelelwa kwezinto ezingcolileyo eziqhubekayo kwindawo.
Ubuthi obuphantsi: I-HEC izinzile kwisisombululo esinamanzi, inetyhefu ephantsi kwi-ecosystem, kwaye ifanelekile ngamaxesha aneemfuno eziphezulu zokusingqongileyo.
Ukunyibilika kwamanzi kunye nokuqina: I-HEC inokunyibilika emanzini kwaye yenze isisombululo esiphezulu se-viscosity, esenza ukuba siphumelele ekulungiseni i-rheology kunye nokumiswa kweempawu zolwelo.
Izicelo eziphambili kwishishini leoli
Ukusetyenziswa kulwelo lokomba
I-drilling fluid iyinxalenye ebalulekileyo kwinkqubo yokukhutshwa kweoli, kwaye ukusebenza kwayo kuchaphazela ngokuthe ngqo ukusebenza kakuhle kunye nokukhusela ukubunjwa. I-HEC, njenge-thickener kunye ne-fluid loss reducer, inokuphucula ngokufanelekileyo iipropathi ze-rheological ze-drilling fluids, ngelixa unciphisa ukungena kwamanzi ekubunjweni kunye nokunciphisa umngcipheko womonakalo wokwakheka. Xa kuthelekiswa neepolima zokwenziwa zemveli, i-HEC inomngcipheko omncinci wongcoliseko kumhlaba ojikelezileyo kunye namanzi aphantsi komhlaba ngenxa yetyhefu ephantsi kunye nokonakala.
Ukusetyenziswa kulwelo oluqhekezayo
Ngexesha lenkqubo yokuqhekeka, i-fracturing fluid isetyenziselwa ukwandiswa kwe-fracture kunye nokuthwala isanti. I-HEC ingasetyenziselwa njenge-thickener ye-fracturing fluid, iphucula i-viscosity ye-liquid ukuphucula umthamo wokuthwala isanti, kwaye xa kuyimfuneko, inokuthotywa yi-enzymes okanye i-acids ukukhulula i-fractures kunye nokubuyisela ukubunjwa kwe-permeability. Esi sixhobo sokulawula ukuthotywa kunceda ukunciphisa iintsalela zeekhemikhali, ngaloo ndlela kuncitshiswe iziphumo zexesha elide kwiinkqubo kunye neenkqubo zamanzi aphantsi komhlaba.
Ukuzinzisa udaka kunye nokuthintela ukulahleka kwamanzi
I-HEC isetyenziselwa ngokubanzi njenge-stabilizer yodaka kunye nokuthintela ukulahleka kwamanzi, ngakumbi phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu. Ukuzinza kwayo okugqwesileyo kunye nokunyibilika kwamanzi kunokunciphisa kakhulu ukulahleka kwamanzi odaka kunye nokukhusela ingqibelelo yokwakheka. Kwangaxeshanye, ekubeni i-HEC ingasetyenziswa ngokudibeneyo nezinye izongezo ezihambelana nokusingqongileyo, ukusetyenziswa kwayo kunciphisa ngakumbi ingozi yokusingqongileyo.
Impembelelo yokusingqongileyo
Ukunciphisa ukungcoliseka kwendalo
Izongezo zeekhemikhali eziqhelekileyo ezifana ne-synthetic polyacrylamide izinto zihlala zine-eco-toxicity ephezulu, ngelixa i-HEC, ngenxa yemvelaphi yayo yendalo kunye netyhefu ephantsi, inciphisa kakhulu ubunzima bonyango lwenkunkuma kunye nemingcipheko yokungcoliseka kwendalo xa isetyenziswa kwishishini leoli.
Xhasa uphuhliso oluzinzileyo
Ubume be-biodegradable be-HEC buyenza ikwazi ukubola ngokuthe ngcembe ibe zizinto ezingenabungozi kwindalo, ezinceda ukufezekisa unyango oluluhlaza lwenkunkuma yoshishino lwe-oyile. Ukongeza, iimpawu zayo eziphuma kwimithombo ehlaziyekayo nazo zihambelana nombono wophuhliso oluzinzileyo lwehlabathi.
Nciphisa umonakalo okwesibini wokusingqongileyo
Umonakalo wokwakheka kunye neentsalela zeekhemikhali zezona ngxaki ziphambili zokusingqongileyo kwinkqubo yokukhutshwa kweoli. I-HEC inciphisa kakhulu umngcipheko wongcoliseko lwesibini kumanzi kunye nomhlaba ngelixa unciphisa umonakalo wokwakheka kunye nokuphucula iinkqubo zokugaya kunye ne-fracturing. Olu phawu luyenza ibe yindlela eluhlaza kwiikhemikhali zemveli.
Imingeni kunye nophuhliso lwexesha elizayo
NangonaI-HECibonise iingenelo ezibalulekileyo ekukhuselweni kwendalo kunye nokusebenza, ixabiso layo eliphezulu kunye nokunciphisa ukusebenza phantsi kweemeko ezinzima (ezifana nokushisa okuphezulu, ityuwa ephezulu, njl. njl.) zisekho izinto ezinciphisa ukukhuthazwa kwayo ngokubanzi. Uphando lwexesha elizayo lunokugxila ekuguqulweni kwesakhiwo se-HEC ukuqhubela phambili ukuphucula ukuxhathisa ityuwa kunye nokuzinza okuphezulu kweqondo lokushisa. Ukukhuthaza ukusetyenziswa komgangatho omkhulu kunye nomgangatho we-HEC kushishino lwe-oyile kungundoqo ekuqondeni amandla ayo okukhusela okusingqongileyo.
I-HEC idlala indima ebalulekileyo kwishishini leoli ngenxa yokusebenza kwayo okugqwesileyo kunye neempawu zokukhuselwa kwendalo. Ngokuphucula ukusebenza kwe-drilling fluids, i-fracturing fluids kunye nodaka, i-KimaCell®HEC ayiphuculi kuphela ukusebenza kakuhle kwe-oyile, kodwa inciphisa kakhulu impembelelo embi kwindalo. Ngaphantsi kwendlela yokuguqulwa kwamandla ohlaza kwihlabathi jikelele, ukukhuthazwa kunye nokusetyenziswa kwe-HEC kuya kunika inkxaso eqinile kuphuhliso oluzinzileyo lweshishini leoli.
