摘　　要：环空电缆直读测试技术,可实时监测非自喷井压力随时间的变化数据,获取测试井的地层有效渗透率、井的完善程度及地层压力等参数,从而了解油藏的储层特性。特别是在干扰试井中的应用,更加显示出该技术的优越性,可实时监测测试井数据、实时对测试数据进行分析,从而确定准确的测试时间,了解井的连通情况,为油藏精细描述、调整开发方案进行下一步措施提供了直接依据。弥补了其它非自喷井(随泵、液面、环空钢丝存储)的不足,拓宽了非自喷井的测试领域。Annulus cable readout testing technology,which can monitor changing data of pressure with time of unflowing well at real-time,acquire reservoir parameters of the effective permeability,degree of perfection,formation pressure ects so as to knowledge reservoir properties.Especially that application of it in interference well,shows the advantages of this technique,monitors logging and testing data,analyzes tested data at real-time to determine the accuracy of the test of time,understand well's connecting situation and provide direct basis for fine reservoir description,the next step of treatment for adjustment and development plan.It makes up the shortfall of unflowing wells(with pump,liquid surface,annulus steel storage),widens the testing field of unflowing wells.
