摘要
为了揭示剩余油形成条件及其分布规律，以确保油田的稳产，以胜坨油田二区沙二段７、８砂组为例，进行了微型构造形态与剩余油分布关系的研究。研究表明，该区的微构造类型主要为小鼻状构造，是由于受右行扭应力作用而形成的。利用测井多井解释结果分析了微型构造对剩余油分布的影响。微型构造对油井的生产起着控制作用，在其顶部翼部是剩余油相对富集的地方。
A relationship between mini structure and distribution of the remaining oil in Shentuo oil field was studied by taking seventh and eighth sand groups of second section in second region of Shengtuo oil field as examples. The effects of the mini structure on the distribution of remaining oil were analyzed by using logging explanation data. The main type of mini structure is featured by a small nose like structure formed by right twisting forces. The remaining oil is accumulated at the top and the sides of the mini structures, and is controlled by the mini structute.
