电位法井间测试技术在稠油蒸汽驱中的应用——以辽河油区小洼油田为例

Application of interwell testing by electric potential in heavy oil steam drive ——A case study of Xiaowa Oilfield in Liaohe Basin

电位法井间测试是一种新型、有效的应用于油藏动态监测的技术之一,它能够准确地测定注入介质(蒸汽或水)的推进方位及波及范围。2004年应用该方法在小洼油田蒸汽驱先导试验井组进行了现场测试,确定了注入蒸汽的扩散方向和运动规律,其测试结果与油井生产动态吻合,据此进行开发调整后,取得了较好的汽驱效果。

Interwell testing by electric potential is a new,effective reservoir dynamic monitoring technique.It can accurately test the advancing direction and swept region of injected media(steam or water).This method was used in the pilot steam drive well group of Xiaowa Oilfield in 2004,and the spreading direction and movement pattern of injected steam were determined.The test result matched with well production performance,and development adjustment had been conducted according to this result,and good response was seen.
