东濮凹陷深层气测井评价及应用

Logging Evaluation of Deep Gas in Dongpu Depression and Its Application

东濮凹陷深层具有比较丰富的油气资源,但由于埋藏深,储层物性差,在测井资料上气层显示特征微弱。在分析深层气的测井微弱显示特征基础上,通过岩心刻度测井技术,建立深层储层参数解释模型,形成了一套利用孔隙度、渗透率、含油气饱和度和含气指数等参数综合判别深层气的方法。在实际资料处理解释和应用中,该方法见到了良好的地质应用效果。

There are abundant oil and gas resources in Dongpu depression. However, the deep depth and poor petrophysical properties of the reservoir make gas-indication difficult to recognize. By calibrating the logging data with coring analysis, an interpretation model for the parameters of deep reservoir is established. Furthermore, an integrated method is developed to identify deep gas reservoir with the parameters such as porosity, permeability, gas saturation, gas index, etc. The interpretation method has produced good geologic application results.
