本文从静态与动态条件出发,对砂岩油、气的规律进行了研究,并提出了采用含油饱和度、孔隙度、岩性系数、以及反映地层侵入区油、水分布规律的侵入系数等独立的参数,应用判别分析这一数学方法,综合地对油、水层进行最优的归类判别,从而达到正确评价油层、油水同层、水层。最终在电子计算机上实现综合评价。这一新型的油、气层评价方法与处理程序已在胜利油田等地进行了广泛验证,并投入了生产应用。两年多来,在发现新油田与正确评价油、气层的勘探工作中,取得了明显的效果。
Based on the static and dynamic conditions, the laws of oil and gas in sandstone are studied, and the independent factors such as oil saturation, porosity, lithology and intrusion coefficient, which reflect the oil and water distribution in the intruded area, are proposed Parameters, the use of discriminant analysis of this mathematical method, the integrated oil and water layer for the best classification discrimination, so as to achieve the correct evaluation of reservoir, oil and water with the same layer, water layer. Finally in the computer to achieve a comprehensive evaluation. This new oil and gas reservoir evaluation method and treatment program has been widely validated in Shengli Oilfield and other places and has been put into production and application. In the past two years, remarkable achievements have been made in the exploration of new oilfields and the correct assessment of oil and gas reservoirs.
