用蒸汽驱改善边底水稠油油藏开采效果

Improving development efficiency of heavy oil reservoir with edge and bottom water by means of steam drive

具有活跃边底水的稠油油藏，在其蒸汽吞吐过程中，边底水侵入给开采动态带来了严重的影响。转入蒸汽驱后，连续注蒸汽起到了抑制边水侵入、改善开采效果和提高原油采收率的作用。

In heavy oil reservoir with active edge and bottom water. the incursion of edge and bottom water has a serious impact on the production performances during steam huff and puff.When converted into steam injection, the continuous steam injection curbs the incursion of edge and bottom water, improves production efficiency and oil recovery.
