摘要:
 JL气田HS组气藏为底水气藏，随着开采年限的增长，气水界面由2010年的-3643 m上升到2017年的-3615 m，导致高含水气井数量越来越多。为此，提出高产水气井压力恢复试井解释方法。采用该方法对JP井进行压力梯度分析，判断井筒内气液界面在-1000 m处；该井压力恢复试井解释时双对数分析导数曲线开始下掉后又上升，有一个突然变化，为此采用内边界为变井筒储集试井解释模型，解释出地层压力337 MPa，储层平均有效渗透率125 mD，较好的处理了井筒中出现相态重新分布问题。该方法可有效提高高产水气井压力恢复试井解释结果的准确性。
Abstract:
HS group gas reservoir in JL gas field is the type of bottom water gas reservoir. With the increase of production years, the gaswater interface rises from -3643 m in 2010 to -3615 m in 2017, which leads to more and more high water cut gas wells. Therefore, the interpretation method of pressure buildup test for high production gas wells is studied. This method is used to analyze pressure gradient of JP well and the gasliquid interface in the wellbore is estimated at the depth of -1000 m. The derivative curve of double logarithmic analysis firstly drops and then rises and there is a sudden change. For this reason, a well test interpretation model with variable wellbore storage reservoir is adopted, the formation pressure is estimated by 337 MPa, average effective permeability is 125 mD, which can well deal with the problem of phase redistribution in wellbore. This method can effectively improve the accuracy of interpretation results of pressure buildup test in high waterproducing gas wells.
