杏北油田高弯度分流河道储层构型特征和剩余油分布模式
RESERVOIR ARCHITECTURE CHARACTERISTICS AND REMAINED OIL DISTRIBUTION PATTERNS FOR THE HIGH-SINUOSITY DISTRIBUTARY CHANNEL IN XINGBEI OILFIELD
摘要
Abstract
Taking the high-sinuosity distributary-channel reservoir in the close well-spacing block of Xingbei Oilfield as an example,based on the depositional model of the reservoir architecture theory,with the help of analytical hierarchy process,the reservoir architectures were analyzed in detail in the following four aspects:channel complex,individual channel,point bar and lateral accretion body within the point bar,on the basis of the mutual verification of “the static remained oil analysis” interpreted by the close coring well and watered well logging and " the dynamic remained oil analysis" conducted by the numerical simulation of 3D architectural-element model oil reservoir,the distributed modes of the remained oil in the high-sinuosity distributary-channel reservoir were summarized.The achievements show that within the channel,the remained oil are primarily distributed on the upper part of the point bar;while outside the channel,the remained oil are mainly on the top of the point bar and the blocked part by the abandoned channel,the dead-ends of the overbank sandbody and the isolated overbank sandbody with the inefficient injection-production system,and moreover the thin-bedded overbank sandbody with much poorer developed degree.关键词
