大慶油田杏北地區(qū)三角洲前緣相席狀砂和表外儲層發(fā)育，為了充分挖掘高含水期薄差儲層的剩余油潛力，提出了適于三角洲前緣薄差儲層的精細描述方法，給出了該描述方法的具體步驟，并采用地質(zhì)建模技術建立了杏北地區(qū)8個區(qū)塊的儲層精細模型，為優(yōu)化二次加密井射孔方案、優(yōu)選油水井措施方案提供了地質(zhì)依據(jù).
Delta front facies reservoir of Xingbei area in Daqing oil field has good matting-shaped sandstone, To recover residual oil better in thin and low-penetrability formation, we put forward the way of detailed description of delta front facies reservoir including the main steps, and the modeling technology which fits delta front facies reservoir. This way of detailed description has been applied in Xingbei area in Daqing oil field to improve not only the injection programs of the readjusted wells but also the programs of all kinds of stimulations.
