摘要
产能试井是评价油气井产能、指导油田开发的重要手段,常用的方法有回压试井、等时试井和修正等时试井等,这些试井方法要求取得至少1个点的稳定测试资料,用于无阻流量计算和产能评价。针对某些油气藏,若要取得稳定流动资料,需要较长的测试时间,甚至由于油气藏非均质等原因导致测试过程中不能取得稳定测试资料,影响产能评价等问题,提出软件模拟试井方法,并对该方法的可靠性和实际操作进行了研究。
Productivity test is an important mean to evaluate oil and gas wells productivity and guide oilfield development. Some commonly used methods include backpressure test,isochronal test,and modified isochronal test,which all require obtaining at least a point of stable test data to be used for calculating open flow and evaluating productivity. For some reservoirs,a longer test should be needed if you want to obtain steady flow data. Even worse,due to reservoirs heterogeneity,the stable test data can not be obtained,resulting in affecting productivity evaluation. So,in this study,a test method using software simulation is proposed,and its reliability and actual operation are analyzed.
