基于实钻测井资料研究剩余油分布的新方法
New method of remaining oil distribution study based on actual drilling logging data
摘要
Abstract
The XX reservoir in Hutubihe formation Cretaceous in Area LU9 Luliang oilfield is a typical low-amplitude and thin-layered sandstone reservoir with high-permeability and bottom-water. Since the large-scale development in 2001, the recovery percent at present was only about 14% while general water cut was up to 72%, which means that the reservoir has entered into the late stage of water-flooding, so study the remaining oil distribution is imperative for this area. A new method of analyzing the remaining oil with actual drilling logging data of nearly drilled well was established in this paper. Making full use of these logging data for all development well during the past five years, combining with the theory of water flooding in bottom water reservoirs, distribution of remaining oil in thin-layered bottom-water reservoir was studied practically and reliably. It turned out that for the 300 m×300 m well pattern, the sweep degree is only 20% in the 100 m~170 m range away from production wells. In other word, the remaining oil is mainly laid on top of layers between production wells with ship-bottom shape.关键词
