摘要
海安凹陷曲塘次凹断裂发育,阜三段砂岩储层岩相变化快,加之长期注水开发的干扰,给新钻井油水层测井解释造成困难。通过对研究区钻测井、分析化验及试油资料分析,对研究区阜三段的储层特征及四性关系进行研究,结果表明:研究区阜三段主要发育中孔中低渗储层,岩性以粉砂岩和泥质粉砂岩为主,储层岩性、物性的差异控制了油藏的富集程度,在岩性相同的情况下,含油性取决于物性的好坏。在此基础上建立油水层解释图版,得出该区油水层电性识别标准,对提高该区测井解释符合率具有一定的意义。
The faults have developed in Qutang sub-sag of Hai＇an sag, lithofacies change of Fu 3 sandstone reservoir is rapid, and due to the disturbance of long-term water injection development, it is difficult to interpret new drilling oil and water layers using logging data. In this paper, through comprehensive analysis of drilling, logging, assaying and test data in the study area, the reservoir characteristics and four-property relationship in Fu 3 member were studied. The results showed that the lithology of Fu 3 reservoir is dominated by siltstone and siltstone, the difference in lithology and physical properties of reservoir controls the hydrocarbon enrichment of the reservoir. When the reservoir lithology is the same, the hydrocarbon enrichment of reservoirs depends on the property of reservoirs. On this basis, the interpretation map of the oil-water layer was established, and the electrical identification standard for the oil-water layer in the area was obtained, which has certain significance for improving the consistency rate of logging interpretation in the area.
