胜海地区是胜利油田重要的资源增补阵地。该区存在明化镇组、馆陶组、东营组、沙河街组、中生界、古生界、太古界等 7套含油层系 ,其中馆陶组上段是最有利的含油层系之一 ,但勘探难度大 ,主要原因是该层系储集层薄、横向变化大、钻井稀少。通过测井资料的统计分析、建立地质模型以及地震正演模拟 ,对该地区馆上段的地震地质特征、油气藏的地球物理机制和物性特征做了深入的剖析 ,在此基础上提出并研究了适合本区油气藏勘探开发的几种地震方法 ,包括叠后地震多参数分析技术、叠前道集分析技术 (AVO、FVO等 )、叠加速度谱分析应用技术等 ,这些方法在该区几个区块油气藏的预测与描述中取得了理想效果 ,大幅度降低了海上钻井的高投入、勘探开发的高风险。这无疑对胜利油田广大的滩海以及类似地区未来的勘探开发具有重要的指导意义。图 3表 1参 5(王延光摘 )
Shenghai area is Shengli Oilfield an important resource supplement positions. There are 7 oil-bearing formations in the Minghuazhen, Guantao, Dongying, Shahejie, Mesozoic, Paleozoic, Archean, etc. The Upper Guantao Formation is one of the most favorable oil-bearing strata , But the exploration is difficult, mainly due to the thin reservoir layer, lateral changes, drilling rare. Through the statistical analysis of logging data, the establishment of geological model and seismic forward modeling, the seismic geologic characteristics of Upper Palaeoenia in the area, the geophysical mechanism and physical properties of the reservoirs have been deeply analyzed. Based on this, Several seismic methods suitable for the exploration and development of oil and gas reservoirs in this area include multi-parameter analysis technology of post-earthquake seismic, AVO and FVO etc., application technologies of superimposed velocity spectrum analysis, etc., The prediction and description of block reservoirs have achieved the desired results, greatly reducing the high investment in offshore drilling and the high risk of exploration and development. This undoubtedly has an important guiding significance for the vast sea of Shengli Oilfield and its future exploration and development in similar areas.
