对八面河区块进行勘探后发现,对沙河街组构造油藏进行勘探的难度很大,而隐蔽油藏则相对容易,为了能更大程度的发现及了解隐蔽油藏,通过室内分析相关的现场测井资料,对沙河街组层序、沉积及成藏进行了系统的分析研究。并对其沉积体系进行了相关分析研究,系统的对该区块的沙河街组进行了地层层序、地层格架的创建。在地层层序及格架中,结合该区块上多个探井及单井沉积体系的相关分析研究资料,对研究区中单井相以及联井相进行了对应的分析研究,结合其沉积分布情况和储层结构特征,对沙河街组的各种圈闭类型以及对应的分布规律进行了分析说明,为寻找隐蔽圈闭提供了有利的依据。
Exploration of the Bamianhe block shows that it is very difficult to explore the structural reservoirs in the Shahejie formation and the subtle reservoirs are relatively easy. In order to discover and understand the hidden reservoirs to a greater extent, Field logging data, systematic analysis of the Shahejie formation sequence, sedimentation and reservoir formation. The sedimentary system was analyzed and studied systematically, and the stratigraphic sequence and stratigraphic framework were established systematically for the Shahejie Formation in this block. In the sequence and framework of stratigraphy, combining the analysis and research data of multiple exploration wells and single-well sedimentary system in the block, the single-well facies and associated facies in the study area are analyzed and studied correspondingly. Combined with the sedimentary distribution And the characteristics of reservoir structure, analyzes various trap types and corresponding distribution rules of Shahejie Formation, and provides a favorable basis for finding hidden traps.
