7、全部建成投产并竣工决算的项目。2.2项目实施完成后正常生产三年以上，资料齐全，开发生产指标可以预测并能与方案设计指标进行对比。2.3后评估必须坚持客观、公正、实事求是。油藏工程后评估3.1油田地质3.1.1构造通过方案钻井实施，分析油藏构造形态、断层、裂缝分布与方案符合情况。3.1.2储层利用实施钻井资料和储层预测新方法重新认识油藏储层特征及变化情况。3.1.3流体性质及分布通过新井资料，分析油藏流体性质及分布，评价认识符合程度。3.1.4油藏类型根据构造、储层、流体性质确定油藏类型并与方案进行对比。3

8、.1.5地质储f对比分析方案实施前后的含油面积、油层有效厚度、孔隙度、原始含油饱和度、地面原油密度、原油体积系数，评价地质储量的落实程度和变化情况。32油藏工程方案3.2.1开发方式根据对油藏地质特征的认识，评价开发方式适应性。3.2.2层系评价每套层系内的油层数、油层有效厚度、非均质程度、隔层、产能，分析其层系划分是否合理。3.2.3并网评价井网对油藏的适应性及经济有效性。3.2.4注采压力系统根据开发方案实施状况，从注水压力、地层压力、
