大庆油田已处于高含水后期,地下的油水分布越来越复杂,水淹导致地层参数改变,如何准确识别水淹层,成为工作的重点。本文主要介绍水淹层的测井技术,为水淹层的识别提供依据。 Daqing Oilfield is already in the late stage of high water cut. The oil-water distribution in the underground is getting more and more complicated. The flooding causes the change of formation parameters. How to accurately identify the flooded layer becomes the focus of the work. This paper mainly introduces the logging technology of the flooded layer, which provides the basis for identifying the flooded layer.
