摘要

页岩气藏储层特征评价是页岩气藏勘探开发过程中的一个重要环节,其主要目的在于找出储层的资源富集层段,以及为后续的勘探开发提供合理的理论指导与建议。以页岩Ⅰ区块储层为例,在储层孔隙度、渗透率、吸附气丰度等相关属性参数的基础上,结合国内外储层评价标准,对研究区块页岩储层进行综合评价、非均质性评价、物性分析、岩石力学特征剖析等,同时根据计算所得的各亚段储量,对页岩气藏富集层段进行预测。认为研究区块页岩储层非均质程度弱,储层整体较好,有一定的资源规模,在纵向上,目的层段从上往下,储层物性逐渐变好,且1-2亚段和1-1亚段为页岩气资源的富集层段,将是开发的主要层段。
The evaluation of shale gas reservoir characteristics is an important part in the exploration and development of shale gas reservoir, whose main purpose is to find out the enrichment resource zones and to provide reasonable theoretical guidance and suggestions for the subsequent exploration and development. Take No.Ⅰ Block of shale reservoir as an example, the evaluation and analysis of shale reservoir have been conducted in the studying area, including comprehensive evaluation, heterogeneity evaluation, physical property and rock mechanics characteristics analysis on the basis of relevant property parameters, such as porosity, permeability, adsorption gas abundance, etc., combined with the reservoir evaluation standards at home and abroad. At the same time, the shale gas enrichment zone was predicted in terms of the calculated reserves in each sub-layer. The results showed that the heterogeneity of shale reservoir in the studying area was weak with good integrity of reservoir and certain resource scale. The reservoir physical properties gradually become better from top to bottom vertically, and the sub-layer No.1-2 and No.1-1were enrichment zones of shale gas reservoir, which would be the main development zones.
