潍北油田孔一段储层随机建模

在潍北地区孔一段油藏描述中,应用地质统计学随机模拟技术对孔一段储层物性参数进行了研 究,建立了能够反映储层非均质性的地质模型。潍北地区孔一段主要沉积类型为扇三角洲,相变快,沉积 环境不稳定,储层非均质性很强。通过对该地区地层、测井和沉积特征的深入研究,划分出精细的小层 单元,并结合储层宏观和微观非均质性研究,选择出合适的建模方法,建立砂体分布及储层参数模型, 并对结果进行了分析校验。

Stochastic Modeling of Kongyi Reservoir in Weibei Oilfield

In interpreting the reservoirs in the member of Kongyi Formation, geologic statistical and stochastic modeling is used to analyze the physical parameters of reservoirs in Kongyi member, a geologic model reflecting reservoir hetero gcneity is established. The main types of deposition in Kongyi member of Weibei area is fan-delta deposition with fast fa cies change, unstable sedimentary environment and strong heterogeneity. By deeply studying the characteristics of geology, well logging and deposition in the area, precision subzone units are established in combination with microscopic and macroscopic heterogeneous study. Methods for modeling are selected, by which models of sandbody distribution and res ervoir parameters arc established for correcting the results.
