摘要:
 针对酸性气藏深井产能试井测试风险大、测试时间短难以达到稳定流动影响测试结果准确性的难题，考虑关井后续流造成的压降，建立了耦合井筒流动与地层渗流的酸性气藏深井产能试井模型，通过Laplace变换和数值反演进行求解，根据压力恢复试井解释结果设计4个生产制度，模拟压力变化直到达到稳定流动，利用稳定流动对应的产量和压力点回归产能方程，形成产能试井新方法。结果表明，渗透率为0.21×10-3μm2的储层，气井达到稳定流动需要近1000 h，而采用该方法仅依靠1次压力恢复测试数据，通过模拟4个生产制度下的流动即可求取具有较高精度的气井产能方程和无阻流量。该方法对缩短酸性气藏深井产能试井测试周期，降低复杂事故，提高产能试井的准确性具有重要作用。
Abstract:
 Deliverability test for deep wells in sour gas reservoir involves high risks and short duration, making it impossible to realize steady flow, which finally impedes the accuracy of test result. With consideration to pressure drops induced by continuous flows after shutin, a deliverability test model coupled with wellbore flow and formation seepage was built for deep wells in sour gas reservoirs. This model was solved using the Laplace transform and numerical inversion. According to the interpretation results for buildup well test, four production systems were developed to simulate pressure changes till reaching the steady flow. Then, production and pressure points corresponding with the steady flow were used for regression of deliverability equation to generate a new deliverability test method. A gas well in reservoir with permeability of 021×10-3 μm2 may take almost 1000 h to reach steady flow; however, by using the new method, highaccuracy deliverability equation and openflow capacity of the gas well can be obtained by using only the data of one buildup test and through simulating the flows in four production systems. The new method is of great importance to minimize the time required for deliverability test for deep wells in sour gas reservoirs, reduce the complexities and enhance the accuracy of deliverability test.
