利用灰色理论进行多井储层评价

在用灰色理论对油气储层进行精细评价解释的基础上,研究了哈南油田夫特构造砾岩储层和福山凹陷流三段储层的综合评价和多井解释。以关键井分析计算储层参数,利用岩性、物性及含油气变化进行参数集总和归纳,绘制出相应层段储层厚度、孔隙度、渗透率、饱和度等参数分布图,建立了客观反映储层地质特性的分析方法和解释模型。研究了油气储层的基本形态、几何特征及其空间分布规律。从而较好地预测各层段中储油物性好、含油饱和度高的部位,提供了进一步钻探评价位置和范围。

Multiwell Evaluation of Reservoirs by Using Gray Theory

On the basis of studying the precise evaluation and interpretation of reservoir by using gray theory, the synthetic evaluation and multiwell interpretation is studied of the conglomerate reservoir of Fute structure and the third segment reservoir of Fushan Segs in Hanan Oilfield, The reservoir parameters are obtained by collecting and reducing of the key wells' parameters (lithology, physical property and the change of oil and gas content). In the paper are given the distribution diagrams of reservoir parameters (reservoir thickness, porosity, permeability, oil saturation) of corresponding intervals, are established the method and the interpretation model of studying the geological properties of reservoirs, and are also studied the basic morphologies, geometric features and laws of space distribution of the reservoirs. According to these data, the places in each interval can be forecast in which oil is of high quality and high saturation, which will supply the important bases for further exploration and development.
