油页岩地层测井解释评价技术探讨

On Oil Shale Reservoir Log Evaluation Technique

介绍了油页岩储层的岩性特征、矿物组成、物性和品质特征,它的测井响应特征及解释评价方法与常规油气层存在明显区别。利用测井资料,针对油页岩地层特点,在岩性判别、矿物组分处理、物性参数求取、有机碳含量、含油率、裂缝评价、岩石力学参数等方面进行了研究。通过和岩屑、岩心等资料分析对比,油页岩地层测井解释定量评价结果、试油层段选择、压裂方案制定等均能满足勘探开发等方面的技术需求。油页岩储层测井评价技术对其他非常规油气层解释技术的深入研究有着重要的参考意义。

The lithologic character, mineral composition, physical property and quality characteristics of oil shale reservoir are introduced. There are obvious differences in well logging response characteristics and interpretation evaluation methods between oil shale reservoir and conventional oil and gas reservoir. Logging data are used to study the following aspects of the reservoir, lithologic identification, mineral composition, physical parameters calculation, organic carbon content, oil content, fracture evaluation, rock mechanics parameters, and so on. And through cuttings, core data analysis and comparison, the results of quantitative evaluation of the reservoir log data, testing interval selection, and fracturing plans can meet the technical needs of reservoir exploration and development. The reservoir log evaluation technique is an important reference to further study other non-conventional oil and gas zone interpretation methods.
