应用注水井弱脉冲试井技术解决油藏开发难题

Applying the Weak Pulse Testing Technology in Water- Injection to Solve the Difficult Problem of Reservoir's Development.

以注水井为观察井 ,油井为激动井的弱脉冲试井新技术 ,不仅可以判断井间连通关系 ,评价地层参数 ,而且还可以避免由于油井在测试中关井造成的原油损失 ,降低测试成本。通过对文10 2 12等六井组注水井弱脉冲干扰试井的现场施工 ,提出了一套适合于注水井弱脉冲干扰试井的分析方法。资料解释结果符合油藏生产实际情况 。

The new weak pulse testing technique, utilizing water injection wells as measurement wells and oil wells as stimulative one, can not only determine the interconnection relations between the wells and evaluate formation parameters, but also can avoid the loss of crude oil caused by closed well in testing period and low the testing cost. By the field operation of weak pulse test to water injection wells in six wells' units, Wen102 12 etc, the paper proposes a set of analysis methods to suit for them. The interpretation results of data are consistent with the actual situation of reservoir's production, which has verified the feasibility of these methods.
