目前中原油田广泛采用注水开发,并且已经进入高和特高含水开发阶段,水淹层解释的难度越来越大,因此进行水淹层解释已是一项非常重要的工作。本文对中原油田重点区块文33块沙二下油藏水淹层的电性特征进行研究,以期建立一套适合该区水淹层研究的图版。 At present, Zhongyuan Oilfield is widely used in waterflooding development and has entered the high and extra-high water-cut development stage. It is more and more difficult to interpret the flooded layer. Therefore, it is a very important task to explain the flooded layer. In this paper, the electrical characteristics of the waterflooded layer of the reservoir sandstone in Wenzhong 33, a key block of Zhongyuan Oilfield, are studied in order to establish a set of plates suitable for the study of the waterflooded layer in this area.
