马寨油田卫349块复杂带油藏评价技术研究

On the Reservoir Assessment Technique of Difficult Terrain in Wei 349 Block,Mazhai Oilfield

以沉积相为指导,对马寨油田卫349块复杂带地质特点及油气富集规律的认识,并结合储层预测,精细研究砂体展布,充分利用高精度三维地震资料,精细刻画小断层、小断块,精细部署井位,明确油藏结构。寻找有效储层相对发育带,提高油层产能。

Based on sedimentary facies theories and the knowledge of geological traits and oil-gas concentration patterns of the difficult terrains in Wei 349 Block, Mazhai Oil Field, this paper had applied reservoir projection to the study of sand body spread and also used 3D seismic data of high accuracy to depict the details of small faults and fault blocks which could help specify on well net location as well as reservoir structures. All these efforts can lead to the discovery of relative developing zones in order to improve the output of the valid reservoirs.
