我国东部断陷湖盆的主要石油地质特征是断块小、岩性岩相变化大、油气地质条件复杂。这些特征同时也是制约油气勘探开发的主要因素。该文通过复杂断块区的油藏描述研究,首次提出了利用一口探井探明一个断块的综合勘探技术。该技术基于现有常规的地质、地震、测井和地层测试等资 The main petroleum geological features of the fault-depression lacustrine basin in the east of China are small fault blocks, large lithofacies facies changes, and complex geological conditions of oil and gas. These features are also the main factors restricting oil and gas exploration and development. This paper presents the first comprehensive exploration technology that uses a single exploration well to find a fault block through reservoir description research in complex fault block area. The technology is based on existing conventional geology, earthquakes, logging and formation testing
