胜利油区聚合物驱资源分类标准修订及其评价

<title>andard revision and evaluation of resources classification for polymer flooding in Shengli petroliferous province.

胜利油区聚合物驱资源分类标准的修订,充分考虑了已实施聚合物驱单元的情况,采用室内试验和数值模拟等手段,从地层原油粘度、地层温度、空气渗透率、地层水矿化度、二价离子含量及储量规模等方面进行了研究,给出了胜利油区聚合物驱资源分类标准。运用新标准对胜利油区聚合物驱资源进行了分类评价,评价结果较二次资源评价时有较大变化。

<abstract>sed on the analysis of polymer flooding reservoirs, combining with laboratory experiment and numerical simulation, classification standard of polymer flooding resources was revised for Shengli petroliferous province. By studying such factors as crude oil viscosity, formation temperature, air permeability, salinity of formation water, ion concentration and reserve scale, new classification standard is established. And the polymer flooding resources in Shengli petroliferous province were evaluated and classified by the new standard. Theresults are largely different from the second resources evaluation.
