摘要:

泥页岩油气储层是目前非常规油气领域备受关注的勘探目标。 以苏北盆地高邮凹陷阜宁组泥页岩地层为研究对象,采用岩心、试油测试等资料刻度测井和录井信息,开展非常规泥页岩油气储层的识别研究。通过分析泥页岩储层类型及其测井与录井响应特征,发现泥页岩储层多数为脆性矿物含量高的灰质泥页岩岩相(发育裂隙),少数为脆性矿物含量低的不含(或少含)灰质的泥页岩岩相。根据这2 种泥页岩储层类型,提出了2 种相应的成因机制解释模型,借鉴气泡图和雷达图较好地显示出了这2 种解释模型的测井与录井特征差异,进而建立了基于测井和录井信息相结合的泥页岩储层识别方法,为苏北盆地泥页岩油气储层识别及有效开发提供了依据。

Abstract:

Shale oil and gas reservoir becomes a concerned target in unconventional oil and gas exploration. Taking shale strata of Funing Formation in Gaoyou Sag of Subei Basin as a research subject, this paper used core and testing oil data to demarcate well logging and log information, and further to research the recognition method of unconventional shale oil reservoir. Through the analysis of shale reservoir types and its well logging and log response characteristics, it was found that most shale reservoirs developed calcite lithofacies (crack) with high content of brittleness mineral, and a few developed mudstone facies with low content of brittleness mineral and containing or not containing calcareous. In view of these two kinds of shale reservoir types, the corresponding two kinds of interpretation model were put forward. The bubble chart and radar map can be used to show the differences between two models. The identification method of shale reservoir based on the combination between well logging and log infor mation were established, which can  provide a basis for shale oil and gas reservoir recognition and effective development in Subei Basin.
