摘要
针对辽河沈84块沙三段下部高含水期高凝油藏储层水淹状况和特征,依据灰色系统油田开发分析方法及准则,利用测井、钻井取心、试油及有关地质资料,匹配、拟合和提取参数,分别以其特征性参数对高含水期油藏岩性、物性和水淹状况进行统计,采用正态统计特征值建立测井评价参数标准,以其准确率和分辨率自动组合放大,建立测井评价参数标准的权系数。通过该区沙三下的174口井高凝油藏水淹层测井评价参数研究的分析解释,划分出砂砾岩、含砾砂岩、中粗砂岩、细砂岩、粉砂岩和泥岩等岩性剖面,评价解释了不同类型的储层以及不同物性的油层、弱水淹层、中水淹层、强水淹层及水层,阐明了沈84块沙三下高凝油藏水淹状况及剩余油纵向分布规律。
Accounting for the water flooded conditions be-
low the Sha 3 segment of high water-cut stage in
block Shen-84. LiaoHe Oilfield, we determined the
reservoir lithology, physical properties and water
flooded conditions by gray theory. Appraisal parame-
ters are determined according to the characteristic
values of normal distribution. The weight coeffi-
cients of different appraisal parameters are calculated
from well logging, cores, test, and geologic data.
The water flooded conditions and distribution of residual
oil below Sha-3 segment are inferred from 174 wells.
