摘　　要：低产低压油井关井后 ,井筒内出现段塞流 ,测试资料表现出很长的早期段。为了准确分析这类测试资料 ,必须在分析过程中考虑井底续流的影响。本文建立了借助物质平衡原理通过压力数据求取井底续流量的一种简单方法 ,该方法思路清晰 ,简单适用 ,计算结果能够满足试井分析的需要 。To low production and low pressure wells,low pressure makes liquid depth in bore hole to be low before it closed.While,after the well closed,slug flow when fluid around hole bottom flows to well makes testing data to show a long time of early period zone.For analyzing this kind of data accurately,the influence of slug flow should be considered.The paper develops a sample method to solve it based on the principle of material balance which is clear and applicable.The result can feed the need of testing analysis,especially suit for pre-process to test data at early and short time in low production and low pressure wells.
