根据油藏动静态资料综合判断纵向窜流层位及平面窜流方位。纵向窜流层位可根据水井的吸水剖面资料辅以渗透率资料综合判定。吸水百分比较高且渗透率较高的层位即为纵向窜流层位。平面窜流方向可根据沉积相以及油水井的动态变化进行模糊综合判断。按照纵向窜流层位的沉积相是否有利于窜流的形成,对水井周围的油井进行打分,形成沉积相决策因子矩阵;根据周围油井生产动态的变化幅度大小,形成比产液指数决策因子矩阵;采用模糊综合评判方法得到综合评判结果。得分最高的油井所在的方向即是主要的平面窜流方向。该方法在濮城油田的应用表明具有较好的准确性和较高的可靠性。
According to the reservoir dynamic and static data to determine the longitudinal cross-flow stratification plane and cross channel orientation. Longitudinal flow stratification can be based on the water well water profile data supplemented by permeability data comprehensive judgment. The layers with higher water absorption and higher permeability are the longitudinal channeling layers. Plane channeling direction can be based on the sedimentary facies and the dynamic changes of oil wells fuzzy comprehensive judgment. According to whether the sedimentary facies of the stratified reservoirs in the longitudinal direction is favorable for the formation of channeling flow, the wells around the wells are scored to form the matrix of sedimentary facies decision-making factors. According to the variation range of the production dynamics of surrounding oil wells, The comprehensive evaluation result is obtained by fuzzy comprehensive evaluation method. The direction of the highest-scoring oil well is the main planar cross-flow direction. The application of this method in Pucheng Oilfield shows that it has good accuracy and high reliability.
