渤海N区作为中国渤海湾盆地重要的油气勘探区，其变质岩潜山油气藏又是重点研究目标。渤海N区变质岩潜山储层在纵向上的分布和储集类型具有明显变化，具有分带特征，横向非均质性强，连续性差，是一种典型的复杂潜山储层。针对此类储层，常规反演方法的结果对储层的平面展布和纵向分带刻画与地质规律不符，反演效果差。基于传统随机反演方法，引入相控思想，提出一种基于平面分区与纵向分带控制的相控随机反演方法。该方法首先采用波形聚类分析将研究区分为若干平面相似区，然后基于测井分带特征进行纵向分带，最后综合平面分区特征和纵向分带特征约束建模过程、精确随机反演的概率分布范围。针对渤海N区的实际应用表明该技术的反演结果与地质规律相吻合，准确地刻画出了变质岩潜山储层在横向和纵向上的变化规律，为此类复杂潜山油气藏勘探开发提出了一种有效的解决方案，具有重要的实践指导意义。

As an important oil and gas exploration area in Bohai Bay Basin, Bohai N Area, its metamorphic buried hill reservoir is the key research target. The distribution and reservoir types of metamorphic buried hill reservoirs in the N Area of Bohai Sea have obvious changes in the longitudinal direction. It has the characteristics of zoning, strong lateral heterogeneity and poor continuity. It is a typical complex buried hill reservoir. For such reservoirs, the results of conventional inversion methods do not match the geological laws in the plane distribution and vertical zoning of reservoirs, and the inversion effect is poor. Based on the traditional stochastic inversion method, the idea of phase control was introduced, and a phase-controlled stochastic inversion method was proposed based on plane partition and longitudinal zoning control. The waveform clustering analysis was used to divide the study area into several plane similar areas, then vertical zoning based on logging zoning characteristics was performed, and plane zoning characteristics and vertical zoning characteristics was finally synthesized to constrain the modeling process and the probability distribution range of accurate random inversion. The practical application in the N Area of Bohai Sea shows that the inversion results of this technology are consistent with the geological laws, and the horizontal and vertical variation rules of metamorphic rock buried hill reservoirs are accurately depicted, which provides an effective solution for the exploration and development of such complex buried hill reservoirs. It has important practical guiding significance.
