用评价井网按结构层次建立“层系内单储层空间分布格架” ,并预测单砂体 ;在此基础上优选关键元进行层系的垂向综合评价 ,区分主力、非主力油层 ;采用单砂体垂叠进行平面评价 ,预测砂岩及油层发育区块 ;由此实现河流层系的精细立体综合评价。 Based on the structure of the evaluation well pattern, the spatial distribution framework of single reservoirs in the strata is established and the single sand body is predicted. On the basis of this, the key elements are selected for vertical comprehensive evaluation of the strata system to distinguish the main and non-main oil layers. The single sand body is used for vertical plane evaluation, and sandstone and oil layer development blocks are predicted. Thus, a detailed three-dimensional comprehensive evaluation of the river bed system is achieved.
