During indoor or outdoor experiments,we founded the mud system of preventing oozing slurry with main per-formances of dilution shearing(flow resistance reducing),filtration control,against sloughing and so on.
經(jīng)過大量室內(nèi)外實驗,得出以高剪切稀釋(降低流阻)為主要性能指標(biāo),同時兼有降濾失、抑制孔壁失穩(wěn)等性能的防冒漿鉆井液體系。
Results show that colloidalmicrocrystalline cellulose can form gel in water,its solution has the character of shearing-thin,high temperature and pressure can help the colloidal microcrystalline cellulose form gel in water,the solution of colloidalmicrocrystalline cellulose is stable in middle range of pH,Ca2+ may obviously r.
研究了膠態(tài)微晶纖維素在水溶液中的濃度、溶液的pH值、溫度、金屬離子、剪切速率、剪切和靜置時間、熱處理溫度和時間、高壓均質(zhì)處理等對膠態(tài)微晶纖維素粘度的影響,結(jié)果表明:膠態(tài)微晶纖維素在溶液中可形成凝膠,形成的凝膠具有搖溶性,膠態(tài)微晶纖維素溶液具有典型的剪切稀變性和良好的時變性,在低酸性條件下具有較好的穩(wěn)定性,高溫和高壓處理有利于膠態(tài)微晶纖維素在溶液中的分散,二價金屬離子會顯著影響其粘度。
