I-CMC (i-sodium carboxymethyl cellulose) yi-polymer compound ebalulekileyo enyibilikayo emanzini edlala indima ebalulekileyo ekugrumbeni olwandle olujulileyo, ingakumbi ekulungiseleleni nasekusebenzeni kakuhle kolwelo lokugrumba. Ukugrumba olwandle olujulileyo ngumsebenzi oneemfuno zobugcisa eziphezulu kakhulu kunye neemeko ezinzima zokusingqongileyo. Ngophuhliso lwezixhobo zeoyile negesi ezikude nolwandle, ubungakanani kunye nobunzulu bokugrumba olwandle olujulileyo buyanda kancinci kancinci. Njenge-additive yekhemikhali esebenzayo, i-CMC inokuphucula ukusebenza kakuhle, ukhuseleko kunye nokukhuselwa kwendalo kwenkqubo yokugrumba.
1. Indima ephambili kulwelo lokugrumba
Ngexesha lokugrumba emanzini anzulu, ulwelo lokugrumba ludlala imisebenzi ebalulekileyo efana nokuxhasa udonga lomthombo, ukupholisa iqhekeza lokugrumba, ukususa iitships, kunye nokugcina uxinzelelo olungaphantsi komngxuma. I-CMC yi-viscosity regulator esebenzayo, i-rheological agent kunye ne-thickener, esetyenziswa kakhulu ekulungiseleleni ulwelo lokugrumba. Imisebenzi yayo ephambili ibonakala kwezi zinto zilandelayo:
1.1 Ukujiya nokulungisa i-viscosity
Kwimigodi yolwandle olujulileyo, ngenxa yokwanda kobunzulu bamanzi kunye noxinzelelo, ulwelo lokugrumba kufuneka lube nobunzima obuthile ukuqinisekisa ukuba luhamba kakuhle kunye nomthamo wokuthwala. I-CMC inokwenza ulwelo lokugrumba lube lukhuni kwaye incede ukugcina uzinzo lolwelo lokugrumba kubunzulu obahlukeneyo kunye noxinzelelo. Ngokulungisa uxinzelelo lwe-CMC, ubunzulu bolwelo lokugrumba bunokulungiswa ukuqinisekisa ukuba ulwelo lokugrumba luneempawu ezifanelekileyo zokuhamba, ukuze lukwazi ukuhamba ngokukhululekileyo kwiindawo ezinzima zolwandle olujulileyo kwaye luthintele iingxaki ezifana nokuwa kwe-wellbore.
1.2 Ukuphucula iipropati ze-rheological
Iimpawu ze-rheological zolwelo lokugrumba zibalulekile ekugrumbeni olwandle olujulileyo. I-CMC inokuphucula ukugeleza kolwelo lokugrumba, ilwenze luhambe kakuhle ngaphantsi komhlaba, inciphise ukungqubana phakathi kwe-drill bit kunye nodonga olune-wellbore, inciphise ukusetyenziswa kwamandla kunye nokuguga koomatshini ngexesha lokugrumba, kwaye yandise ubomi benkonzo yezixhobo zokugrumba. Ukongeza, iimpawu ezilungileyo ze-rheological zinokuqinisekisa ukuba ulwelo lokugrumba lunokuthwala ngempumelelo iziqwenga kwaye luthintele ukuqokelelwa kwamasuntswana aqinileyo kulwelo lokugrumba, ngaloo ndlela kuthintelwe iingxaki ezifana nokuvaleka.
2. Uzinzo lwe-Wellbore kunye nokuthintela ukwakheka kwe-hydrate
Kwinkqubo yokugrumba emanzini anzulu, uzinzo lwemigodi yeyona nto iphambili. Iindawo ezinzulu zolwandle zihlala zijongene neemeko ezinzima zejografi, ezinje ngoxinzelelo oluphezulu, ubushushu obuphezulu, kunye nokubekwa kwedaka, okunokukhokelela ekuweni kwemigodi okanye ukulahleka kolwelo lokugrumba. I-CMC inceda ekuphuculeni uzinzo lodonga lwemigodi kwaye ithintele ukuwohloka kwemigodi ngokuphucula i-viscosity kunye neempawu ze-rheological zolwelo lokugrumba.
Kwimigodi yolwandle olujulileyo, ukwakheka kwee-hydrate (ezifana nee-hydrate zegesi yendalo) nayo yingxaki engenakuyityeshelwa. Phantsi kweemeko zobushushu obuphantsi kunye noxinzelelo oluphezulu, ii-hydrate zegesi yendalo zenzeka lula ngexesha lenkqubo yokumba kwaye zibangele ukuvaleka kolwelo lokumba. Njengearhente yokufunxa amanzi esebenzayo, i-CMC inokuthintela ngempumelelo ukwakheka kwee-hydrate, igcine ukunyibilika kolwelo lokumba, kwaye iqinisekise inkqubela phambili ethe tye yemisebenzi yokumba.
3. Nciphisa impembelelo yokusingqongileyo
Ngenxa yeemfuno zokhuseleko lokusingqongileyo eziya zisiba nzima, impembelelo kwindalo esingqongileyo ngexesha lokugrumba elwandle olunzulu ifumene ingqwalasela engakumbi. Ukusetyenziswa kwe-CMC ekugrumbeni elwandle olunzulu kunokunciphisa ngempumelelo ukukhutshwa kwezinto eziyingozi kulwelo lokugrumba. Njengezinto zendalo, i-CMC inokubola kakuhle kwaye inobuhlobo nokusingqongileyo. Ukusetyenziswa kwayo kunokunciphisa ubuthi bolwelo lokugrumba kwaye kunciphise ungcoliseko kwindalo yolwandle.
Ukongeza, i-CMC inokuphucula izinga lokurisayikilisha ulwelo lokugrumba. Ngokulungisa ngokufanelekileyo ukusebenza kolwelo lokugrumba, ukunciphisa ukulahleka kolwelo lokugrumba, nokuqinisekisa ukuba ulwelo lokugrumba lunokusetyenziswa kwakhona ngokuphindaphindiweyo, umthwalo okwimeko yolwandle ngexesha lenkqubo yokugrumba uyancitshiswa. Oku kubaluleke kakhulu kuphuhliso oluzinzileyo lokugrumba olwandle olunzulu.
4. Ukuphucula ukusebenza kakuhle nokukhuseleka kokugrumba
Ukusetyenziswa kwe-CMC akuphuculi nje kuphela ukusebenza kolwelo lokugrumba oluselwandle olunzulu, kodwa kukwaphucula nokusebenza kakuhle kokugrumba kunye nokhuseleko lokusebenza ukuya kwinqanaba elithile. Okokuqala, i-CMC ingenza ulwelo lokugrumba lulungelelane ngcono neemeko ezahlukeneyo zejoloji, inciphise imeko yokubhajwa kombhobho kunye nokuvaleka ngexesha lokugrumba, kwaye iqinisekise inkqubela phambili ethe tye kwimisebenzi yokugrumba. Okwesibini, ukusebenza kolwelo lokugrumba oluzinzileyo kunokuphucula ukuchaneka kokugrumba kwaye kuthintele ukusilela kokugrumba okubangelwa ludonga olungazinzanga lomthombo okanye ezinye izinto. Ukongeza, i-CMC inokunciphisa ngempumelelo umngcipheko wokutshintshatshintsha koxinzelelo olungaphantsi komhlaba, inciphise iimeko eziyingozi ezifana nokuqhushumba kunye nokutshiza udaka okunokwenzeka ngexesha lokugrumba, kwaye iqinisekise ukhuseleko lwemisebenzi.
5. Ukusebenza kakuhle kweendleko kunye noqoqosho
Nangona ukusetyenziswa kweI-CMCiya kunyusa iindleko ezithile, ezi ndleko ziyalawuleka xa kuthelekiswa nokuphuculwa kokusebenza kakuhle kokumba kunye nokuqinisekiswa kokhuseleko okuzisayo. I-CMC inokuphucula uzinzo lolwelo lokumba kwaye inciphise imfuneko yezinye izongezo zamakhemikhali, ngaloo ndlela inciphise iindleko zizonke zolwelo lokumba. Kwangaxeshanye, ukusetyenziswa kwe-CMC kunokunciphisa iindleko zokulahleka kwezixhobo kunye nokugcinwa kwazo, kuphucule ukusebenza kakuhle kwemveliso yokusebenza kokumba, kwaye ngaloo ndlela kuzise iingenelo eziphezulu kwezoqoqosho.
Njengesongezo seekhemikhali esisebenza kakuhle kakhulu, i-CMC idlala indima ebalulekileyo ekubholeni elwandle olujulileyo. Ayinakuphucula kuphela ukusebenza kolwelo lokubhola nokuphucula uzinzo lwe-wellbore, kodwa ikwathintela ngokufanelekileyo ukwakheka kwe-hydrate, inciphise ungcoliseko lokusingqongileyo, kwaye iphucule ukusebenza kakuhle kunye nokhuseleko. Ngophuhliso oluqhubekayo lwetekhnoloji yokubhola elwandle olujulileyo kunye nokuphuculwa okuqhubekayo kweemfuno zokhuseleko lokusingqongileyo, ukusetyenziswa kwe-CMC kuya kuba kubanzi ngakumbi kwaye kube yenye yezona zinto zibalulekileyo ekubholeni elwandle olujulileyo.
