摘要
针对包14块复杂的储层和构造条件,依托VSP测井技术、地层划分与对比技术、三维构造地震精细解释技术、地质建模技术及储层反演识别技术的配套应用研究,解决了油藏开发中复杂性和多解性问题,取得了明显的开发效果。新增含油面积5.26 km2,新增石油地质储量396×104t,在新增含油区域内,先后5次滚动扩边部署各类井95口,已实施67口,成功率95%以上,年建产能12.28×104t,采油速度达到1.89%。实践证明:低渗透复杂小断块油藏需要实施滚动勘探开发,应用多学科,研究配套的滚动开发技术,不断深化认识油藏地质特征是改善开发效果的关键。
This paper applies VSP logging technology,strata classification and comparison,3D seismic fine explanation,geological modeling and reservoir inversion recognition to analyze the complicated reservoirs and structures in Bao14 block,clarifies the complexity and multi-answers in oil reservoir development,and acquires good effects.A total of bearing-oil area 5.26 km2 has been newly increased with an up in reserve 396×104 t.In the newly-found oil-bearing area 95 boreholes were allocated in 5 continuing exploration stages,of which 67 ones have been completed with 95% in success.The total yield capacity is 12.28×104 t at oil recovery speed up to 1.89%.It is proven that small fault-block reservoirs with low permeability need continuing exploration and development technologies,and a better understanding in reservoir geology.
