通过对中原油田复杂断块气藏可采储量的研究,提出了气藏可采储量标定的新思路,即以井控地质储量为基础标定可采储量,在对复杂断块气藏开发地质特征总结研究的基础上,进一步探讨了提高可采储量的思路及技术途径。

Based on the research of recoverable reserves for complex fault block gas pool in Zhongyuan Oilfield , a new thought of recoverable reserves calibration was formed. Taking well control geological reserves as basic calibrating recoverable reserves , the seven categories for recoverable reserves were described , suitable methods for gas reservoir in different developing phases were analyzed , and the developing geological features of complex fault block gas pool were studied and summarized. Also the thought and technical method to improve recoverable reserves was furthermore discussed. It is helpful for recoverable reserves calibration and recovery enhancement of similar gas pools.
