深井气井试油合理测试时间确定方法研究

试油是确定气井产能大小的最直接方法,测试时间是否合理,将影响测试得到的数据,从而影响产能的准确确定。根据深井气井的特点,研究了深井气井试油合理测试时间的确定方法、确定的原则和合理测试时间确定应考虑的因素,从多个方面研究了深井测试合理时间的计算,并给出了应用实例。这些研究对深井测试设计具有重要意义。

DETERMINATION OF REASONABLE TESTING DURA-TION FOR DEEP GAS WELL

Well testing is a simple and direct way to determine the deliverability of gas well. However, whether the test duration is long enough or not will affect the readings from the test, which will in turn influence the computation of gas well deliverability.Based on the deep gas well configuration, we investigated themethod, the principle and other factors to estimate the reason-able testing time. We presented a couple of ways to estimate the reasonable testing time, and case study was also provided. We think that our research work is of practical significance in guid-ing test design of deep gas wells.
