鄂尔多斯盆地A油藏成藏规律研究
Research on the Reservoir-Forming Law of the A-Reservoir in the Ordos
摘要: 鄂尔多斯盆地A油藏是长庆油田近年高产勘探开发区块之一。对该区块长6储层系统成藏规律进行研究、优选出有利区，对储量接替、持续稳产，具有重要的现实意义。在区域地质背景分析的基础上，以层序地层学、石油地质学、沉积学理论为指导，应用测井、岩心分析资料等，研究各小层油气富集规律及成藏主控因素并选出有利区。通过分析得出研究区成藏主控因素主要为烃源岩分布、沉积相带控制、物性控制及成岩控制，其中物性因素为主要控制因素，而构造作用影响较小；通过成藏规律研究和生产研究现状分析，明确有利区，为下步增储建产提供了指导，可以有效增加油田产量。
Abstract: A Block in Ordos Basin is one of the high-yield exploration and development zones in Changqing Oilfield in recent years. It is of great practical significance for sustained and stable production to study forming regularity of Chang 6 reservoir system and optimize favorable area. Based on the analysis of regional geological background and the guidance of sequence stratigraphy, petroleum geology, sedimentology theory, the oil and gas enrichment rules and the main control factors of each small layer were studied and the favorable areas were selected by using logging, core analysis data, etc. Results showed that the main control factors in the study area were source rock distribution, sedimentary facies belt control, physical property control and diagenesis control, in which the physical property was the main control factor, while there was little effect of tectonism. Through the study of reservoir forming regularity and the analysis of production status, the favorable area was identified, which could provide guidance for further increase of reservoir and production construction, and effectively improve oil field yield.
