【 摘 要 】

The imperfect zone of injection and production is formed at the side of fault due to lateral occlusion, and the remaining oil is relatively abundant. The horizontal well can enlarge the area of oil discharge, improve the utilization degree of the oil layer, and the horizontal section can pass through the interlayer, so as to effectively excavate the remaining oil at the edge of the fault. To achieve a better level wellblock reservoir prediction effect, based on waveform inversion instructions, the method of waveform indicates inversion of 1 # fault zone of remaining oil prediction method to explore and PII reservoir in the studied area of channel sand body distribution pattern is forecasted, guiding the horizontal well trajectory design. Through the post-test well test of uniform distribution in the whole area, the recognition rate of the channel sand body above 2m is more than 80%, showing a good application prospect of waveform indicator inversion.
