摘要(Abstract)：

喇萨杏油田作为中国最大的陆相多层砂岩油藏,已进入特高含水开发阶段,"三大矛盾"突出,剩余油分布高度零散,现有储层定性评价方法已很难满足当前生产开发的需求。根据特高含水期开发形势及技术发展需求,结合油藏精细地质特征及开发效果,利用多参数乘积法、多参数界限法等方法开展储层评价方法研究,制定了基于砂体储渗能力与集散程度的储层评价方法。新评价方法以储渗参数和优势砂体集散程度为评价参数,构建了地质静态与生产动态的联系,能在一定程度上定量表征储层潜力;评价结果使地质特征相近的储层性质更加接近,便于开发层系的组合;优势砂体连通程度的引入突出了储层平面非均质特征,有利于开发规划部署;储层评价方法实现了储层的定量化表征,能揭示储层属性特征,为水驱、聚合物驱、三元复合驱开发方案的制定提供理论依据。
Lasaxing Oilfields are the maximum continental multi-layered sandstone reservoirs in China,which have already entered the ultra-high watercut development stage and are characterized by more prominent three major contradictions and highly scattered remained oil and moreover the present qualitative reservoir evaluating methods are hard to meet the demands of the current reservoir production and development. According to the production situation and requirements of the technical development at the ultra-high watercut stage,combining with the fine reservoir geological characteristics and development effects,the new reservoir evaluating method was researched and established by using multi-parameter product method,multi-parameter bound analysis,etc. The reservoir storing-permeating parameters and dominant sandbody gather-scatter degree as the assessing parameters of the method proposed,so the relationship between the static geology and dynamic production performances was established,thusthe potential of the quantitative reservoir characterization can be realized in a certain degree; the evaluated achievements make the reservoir properties with the similar geological characteristics even more closer,which is more convenient for the sequence combination of the developed layers; the introduction of the dominant sandbody connectivity degree emphasizes the reservoir planar heterogeneous characteristics,which benefits the deployment of the oilfield development plan; the new reservoir evaluating method can realize the quantitative characterization of the reservoir and reveal the attribute features of the reservoir,so the theoretical evidences have been presented for the compilation of the water,polymer and ASP floodings development programs.
