摘要
埕海油田张巨河开发区沙二段沉积环境为受南部埕宁隆起物源影响下的辫状河三角洲前缘沉积,储层岩性主要为岩屑长石砂岩和长石岩屑砂岩。文章利用测井、录井、岩心、试油和分析化验等资料,对埕海油田张巨河开发区沙二段储层的岩性、物性、电性以及含油性特征进行深入研究,确定了该区沙二段油层有效厚度标准,为该区油层综合评价和储量计算提供可靠的依据。
The sedimentary environment of the second member of Shahejie formation in Zhangjuhe development area of Chenghai Oilfield is braided river delta front deposit influenced by the source of Chengning uplift in the south. The reservoir lithology is mainly lithology of lithie arkose and feldspathie lithie sandstone. In this paper, the lithology, physical properties, electrical properties and oil-bearing characteristics of the second member of Shahejie formation in Zhangjuhe development area of Chenghai Oilfield are studied using logging, core, oil testing and other data. The effective thickness standard of the second member of Shahejie formation in this area is determined, which provides a reliable basis for the comprehensive evaluation of oil layers and the calculation of reserves in this area.
