Ukusetyenziswa kwe-CMC kwiPetroleum

Imodeli yeCMC yodidi lwePetroleum: PAC- HV PAC- LV PAC-L PAC-R PAC-RECMC- HVCMC- LV

1. Imisebenzi yePAC kunye neCMC kwintsimi yeoli imi ngolu hlobo lulandelayo:

1. Udaka oluqulathe i-PAC kunye ne-CMC lunokwenza udonga lwequla lube yikeyiki ebhityileyo kwaye eqinile yokucoca ngokungena kancinci, ukunciphisa ilahleko yamanzi;

2. Emva kokongeza i-PAC kunye ne-CMC eludakeni, i-drilling rig inokufumana amandla aphantsi okucheba, ukuze udaka lube lula ukukhulula igesi ehlanganiswe kuyo, kwaye kwangaxeshanye, i-debris ilahlwe ngokukhawuleza eludakeni. umngxuma;

3. Ukugrumba udaka, njengezinye ii-suspension kunye ne-dispersions, kunobomi obuthile beshelufu. Ukongeza iPAC kunye neCMC ingayenza izinze kwaye yandise ubomi beshelufu.

2. I-PAC kunye ne-CMC zineepropati ezilandelayo ezibalaseleyo kwizicelo ze-oilfield:

1. Iqondo eliphezulu lokutshintshwa, ukufana okuhle kokutshintshwa, i-viscosity ephezulu, i-dosage ephantsi, ukuphucula ngokufanelekileyo ukusetyenziswa kodaka;

2. Ukuxhathisa okulungileyo kokufuma, ukuxhathisa ityuwa kunye nokumelana ne-alkali, ilungele amanzi ahlambulukileyo, amanzi olwandle kunye nodaka olusekelwe kumanzi etyuwa;

3. Umgangatho wekhekhe lodaka olubunjiweyo lulungile kwaye luzinzile, olunokuthi luzinzise ngokufanelekileyo isakhiwo somhlaba esithambileyo kunye nokukhusela udonga lomthombo ukuba lungabikho;

4. Ilungele inkqubo yodaka ekunzima ukuyilawula umxholo wayo kwaye inoluhlu olubanzi lweenguqu.

3. Iimpawu zokusetyenziswa kwe-CMC kunye nePAC kwi-oyile yokomba:

1. Inekhono eliphezulu lokulawula ukulahleka kwamanzi, ngokukodwa i-high-efficiency loss reducer, enokulawula ukulahleka kwamanzi kwinqanaba eliphezulu kwi-dosage ephantsi ngaphandle kokuchaphazela ezinye iimpawu zodaka;

2. Ukumelana nobushushu obuhle kunye nokuxhathisa ityuwa. Ngaphantsi koxinaniso oluthile lwetyuwa, lusenokuba namandla amahle okunciphisa ukulahleka kwamanzi kunye ne-rheology ethile. Emva kokuchithwa emanzini anetyuwa, i-viscosity iphantse ingatshintshi, ngokukodwa ifanelekile kwizicelo ze-offshore. Ukwemba kunye neemfuno zequla elinzulu;

3. Iyakwazi ukulawula kakuhle i-rheology yodaka, ine-thixotropy efanelekileyo, kwaye ifanelekile naluphi na udaka olunamanzi emanzini ahlambulukileyo, amanzi olwandle, kunye namanzi atyumkileyo anetyuwa;

4. Ukongeza, iPAC isetyenziswa njengolwelo lwesamente, olunokuthi luthintele ulwelo ukuba lungangeni kwimibhobho nakwiziqhekeza;

5. I-filtrate elungiselelwe ngePAC inokumelana ne-2% yesisombululo se-KCL (kufuneka ifakwe xa iqwalasela i-filtrate) kwaye ine-solubility enhle, kulula ukuyisebenzisa, inokulungiswa kwisayithi, kwaye inesantya esikhawulezayo se-gelation kunye nekhono elinamandla lokuthwala isanti. Isetyenziswe ekubunjweni, kunye nefuthe layo lokucoca uxinzelelo lihle kakhulu.
