地质统计学反演技术将地震反演方法与随机模拟理论充分结合,能够有效的综合运用地质、测井和地震信息对地下储层进行研究,在充分发挥地震资料横向分辨率优势的同时,具有更高的纵向分辨能力.渤海K油田储量主要集中在明化镇组地层内,发育分流河道型浅水三角洲沉积,储层厚度薄、横向变化大,绝大部分单砂体厚度远远低于地震资料分辨能力的下限,属于超薄储层类型.针对这类储层首次在渤海油田开发阶段引入地质统计学反演方法,并与常规稀疏脉冲反演成果进行对比,该方法能极大提高薄层分辨能力,有效的解决了油田超薄储层预测问题.后续钻井揭示砂岩预测符合率较高,研究成果对K油田开发井的调整与实施起到了很好的指导作用. The geostatistical inversion technique fully combines the seismic inversion method with the stochastic simulation theory, and can effectively use the geological, logging and seismic information to study the underground reservoirs. While giving full play to the advantages of lateral resolution of seismic data, Higher vertical resolution.Bohai K oilfield reserves are mainly concentrated in the Minghuazhen formation, the development of distributary channel shallow water delta deposits, reservoir thickness is thin, lateral changes, the vast majority of single sand body thickness is much lower than the earthquake The lower limit of data resolution is of the ultra-thin reservoir type. For the first time, this kind of reservoir is introduced into the inversion of geostatistics in the development stage of Bohai Oilfield and compared with the results of conventional sparse pulse inversion. Layer resolution ability and effectively solve the problem of ultrathin reservoir prediction in oilfields.The follow-up drilling reveals that the coincidence rate of sandstone prediction is high and the research results play a good guiding role in the adjustment and implementation of development wells in K oilfield.
