板桥油气田沙一段沉积时期,物源来自西北方向的沧县隆起,在板桥斜坡区形成远岸水下扇沉积。储层岩性主要为岩屑长石砂岩。本文利用测井、录井、岩心、试油和分析化验等资料,对板桥油气田沙一段下部砂岩储层的岩性、物性、电性、及含油性特征进行深入研究,确定了该区沙一下油层有效厚度标准,为该区油层综合评价和储量计算提供可靠的依据。
During the deposition of the first member of the Shahejie Formation in Banqiao Oil and Gas Field, the source of the material came from the Cangxian uplift in the northwest direction and formed the offshore submarine fan deposition in the slope area of Banqiao. The reservoir lithology is mainly lithic feldspar sandstone. In this paper, the lithology, physical properties, electrical properties and oil-bearing characteristics of sandstone reservoirs in the lower part of Sha-1 of Banqiao oil and gas field are studied in detail by logging, logging, core logging, oil testing and analysis. The effective thickness of the standard reservoir for comprehensive evaluation of the reservoir and reserves to provide a reliable basis.
