摘要
针对现场实际压力资料处理、储层参数解释应用中发现的多次开关试油井后期关井恢复求导曲线异常的问题,对试井的变产量叠加压力公式进行了分析,找出了试井求导曲线出现异常的原因,并用B302井的压力资料进行了验证。
Abnormal pressure derivative curve of the final build-up appears when using superposition for multi-flow with different rates and multi-shut-in.This paper analyzes superposition pressure formula,finds out the reason of appearing of abnormal pressure derivative curve,and verifies it with the field data of Well B302.
