东营凹陷缓坡带滩坝砂储层描述技术
|
摘要
东营凹陷缓坡带沙四段滩坝砂体储层发育和展布规律复杂,一直是勘探的难点。通过对东营凹陷缓坡带的研究,建立了古地貌分析储层展布区带、地震属性分析描述追踪滩坝砂储层、油气成藏分析确定部署方案的滩坝砂油气藏勘探技术流程,形成了应用高分辨率层序地层、“相似背景”的分离、地层切片分析、超道数据分析、波形分析等一系列适用于滩坝砂体油藏描述的配套勘探技术,并在梁108等多个井区取得勘探突破。
The beach - bar sandbody reservoirs of the 4th member of Shahejie formation were one of the difficulties in exploration due to their complex development and spread rule. Through the study on the gentle slope belt of Dongying Sag, the hydrocarbon exploration technological process was established for reservoir spread zones analysis by palaeogeomorphology, description and trace of the beach - bar sand reservoir by seismic attribute analysis technique, and disposition program determination by hydrocarbon reservoir - forming analysis. A series of exploration technologies suitable for the description of the beach - bar sandbody oil reservoir were formed, which include high - resolution sequence stratigraphy , separation technology under " similar background" , the stratum slice analysis, the superrunning data analysis, waveform analysis technologies. And breakthrough on exploration has achieved in many wellblocks as Liang 108.
