蒸汽驱突破阶段汽窜研究与治理

Research and control of steam channeling in steam flooding breakthrough stage

针对齐40块蒸汽驱整体处于蒸汽突破阶段,汽窜井显著增多的问题,通过对汽窜情况及其成因的研究,并通过对防治汽窜手段的研究,提出了适合齐40蒸汽驱汽窜防治的措施。通过综合治理有效抑制和利用了汽窜,改善了油层动用状况。

Because the entire Qi 40 block reservoir is in the stage of steam breakthrough and the steam channeling wellsare significantly increased,this paper researches the steam channeling situation and its causes,and studies steam channelingcountermeasures,and then puts forward some countermeasures suitable for Qi40 steam channeling prevention and control. Andfinally,through comprehensive treatment,steam channeling is effectively suppressed and used,and reservoir producing degree isalso improved.
