Iqhaza Lezimboni PolyAcrylamide ekukhishweni kwamafutha

Izici ze-polylialialialialial polycacisisiis ukuze zikhule, ukugcwala kanye nokulawulwa kwe-bhedo koketshezi kwenza kube nendima ebalulekile ekukhiqizeni uwoyela. Isetshenziswa kabanzi ekuvuthweni, ukufakwa kwamanzi, ukugcwala amanzi, ukufiphala, ukugeza kahle, ukuqeda kahle, ukuncishiswa kokuhudula, ukuhanjiswa kwesilinganiso kanye nokuhanjiswa kawoyela.

Ngokuvamile, ukusetshenziswa kwePoliyacrylamide ukuthuthukisa izinga lokutakula lamafutha. Ikakhulu, amasimu amaningi kawoyela angenele ukukhiqizwa kwesibili nawesithuthukile, ukujula kwendawo yokugcina amanzi ngokuvamile kungaphezu kwama-1000m, kanti okunye kokujula kwerejista kufinyelela ku-7000m. I-heterogeneity ye-heterogeneity yokwakheka kwama-oyela aphesheya aphesheya kwezilwandle ibeke phambili izimo eziqinile zokubuyiselwa kwamafutha.

Phakathi kwazo, ukukhiqizwa kwamafutha okujulile kanye nokukhiqizwa kowoyela okuvela ku-aidshore ngokulandelana kwayo ku-pam, ukuvumela ukumelana nama-shear, amazinga okushisa aphezulu, kusukela ku-100 ° C kuya ku-200 ° C.

I-PolyAcrylamide ye-Industrial isetshenziswa njenge-dring uketshezi ajud futhi uphumelele isengezo se-fluid:

I-Pollolyzed PoryacryZled (HPAM), ethathwe kwi-hydrolysis ye-polyramide, imvamisa isetshenziswa njengesiguquli se-fluid. Indima yayo ukulawula i-Rheelology yoketshezi lokumba, gqoka ukusikwa, ukunciphisa ukulahleka kwe-dring, njll. Ukudonswa kwamafutha aphansi, okulula ukuthola i-19% ephakeme kunamafutha ajwayelekile, futhi acishe abe ngu-45% ngaphezulu kunesilinganiso sokumba ngomshini.

Ngaphezu kwalokho, inganciphisa kakhulu izingozi zokumba ezinamathekisayo, ukunciphisa ukugqoka kwemishini, futhi kuvikele ukulahleka nokuwa. Ubuchwepheshe bokuqhekeka buyisinyathelo esibalulekile sokuvuselela ukukhulisa imibhede eqinile emasimini kawoyela. I-PolyRacrylamide ecashile uketshezi olusetshenziswa kabanzi ngenxa yokuvunywa kwalo okuphezulu, ukuxabana okuphansi, umthamo omkhulu omisiwe, ukuqina okuncane, ukuqina okuhle, ukulungiswa okuncane, ukulungiswa okulula kanye nezindleko eziphansi.

Ekuphuthuleni nasekusukeni kwe-acidizing, i-polylamide ilungiselelwe kwisisombululo esinamanzi nge-0.01% kuya ku-4% futhi ifakwe ekwakhekeni komhlaba ongaphansi komhlaba ukuze kuphule ukwakheka. Isixazululo sezimboni ze-polylacrylamide sinomsebenzi wokuqina kanye nokuphatha isihlabathi kanye nokunciphisa ukulahleka koketshezi. Ngaphezu kwalokho, i-polylacrylamide inomphumela wokunciphisa ukumelana, ukuze ukulahleka kokudluliswa kwengcindezi kungancishiswa.
