对八面河油田近年来的稠油热采井出砂情况统计分析认为,热采后出砂主要受防砂时间及方式、生产参数、热采轮次、出砂史的影响,放喷过程中压力下降快、下泵生产后动液面下降快等是其主要的表现特征。预防出砂,重点在于实施热采前的防砂处理和热采过程中的产生参数控制。
對八麵河油田近年來的稠油熱採井齣砂情況統計分析認為,熱採後齣砂主要受防砂時間及方式、生產參數、熱採輪次、齣砂史的影響,放噴過程中壓力下降快、下泵生產後動液麵下降快等是其主要的錶現特徵。預防齣砂,重點在于實施熱採前的防砂處理和熱採過程中的產生參數控製。

Statistic analysis of last few years of sand flow from thermal recovery wells in Bamianhe Oilfield concludes that sand flow is caused mainly by the time and method of sand prevention,production parameter,thermal recovery round as well as history of sand flow.Its main performance characteristics are the fast pressure drop in the process of blowout and fast drop of working fluid level when downhole pump starts production.To prevent sand flow,more attention should be paid to sand prevention handling ahead of thermal recovery and emerging parameter control during thermal recovery.
