西部凹陷东部陡坡带角砾岩体储层特征研究--以雷77区块为例

Study on breccia reservoir characteristics on the east steep slope of Western Sag——A case study with Block Lei77

在西部凹陷东部陡坡带雷77区块角砾岩体岩性特征、测井响应特征分析基础上,对该区角砾岩岩相划分、地层归属、储集层特征、储集层控制因素等方面进行了研究,并对该区有利角砾岩储集层发育带进行了预测,指出了在雷77区块北部依然存在有利的角砾岩勘探目标,为该区下步勘探部署提供了依据。

Based on analysis of the lithological characteristics and log response of the breccia rock in Block Lei77 on the east steep slope belt of Western Sag, this paper studies breccia facies classification, formation division, reservoir characteristics and controlling factors, predicts favorable breccia reservoir zones, and points out that there still exists breccia exploration potential in the north of Block Lei77, thus providing basis for further exploration deployment in this area.
