摘要
通过对高孔低渗、低孔低渗等特征含气砂岩的储层岩性、物性对测井响应的不同的特点分析,建立了一套相应的储层参数测井评价方法。这些测井评价方法包括对于高孔低渗储层评价其孔隙性、含油性的库克法;对于低孔、低渗储层建立的测井非相关优化法;储层测井特征值参数权值法等方法。对于不同储层特征,用相应的储层测井评价方法,可有效地得到储层参数。计算结果、岩心分析数据与试气结论吻合,证明所建立的储层测井评价方法是合适的,为类似复杂储层参数研究提供了新思路,具有一定的参考价值。
A suitable log evaluation method reservoir parameters is established on the basis of analyzing different gas-bearing sandstone reservoir such as high-pore and low-filter,and low pore and low filter characteristics, in particular on analyzing different lithology,physical Properties of reservoir. These evaluation methods include Cook method for high-pore and low-filter reservoir, logging-irrelated optimization and Logging feature parameter weighting method for low-porosity and low-permeability reservoir. Use of different logging evaluation methods can be effective reservoir parameters for different reservoir characteristics. The calculation results are coincided with core analysis data and the test. These appropriate log evaluation methods provide novel ideas for studies of complex reservoir and have some application and reference value. They are critical to reservoir parameter studies.
