摘　　要：介绍了电缆式地层测试器的基本功能,通过准噶尔盆地和塔里木盆地的地质应用实例对其在油气田勘探阶段的使用情况作了详细叙述,如在探井中测量地层压力、进行储层渗透性评价、井下取样和现场组份评价。将电缆式地层测试器的测量结果与传统钻杆测试技术测量的结果作对比,分析其测量结果产生差异的原因和电缆式地层测试器使用中应注意的问题。由于地质条件和测试目的不同,可根据实际情况选择使用电缆式地层测试器或钻杆测试技术。指出在国内不少油田,电缆式地层测试器还未能发挥其优势。最后给出了现场使用中的几点具体经验。Some primary functions of wireline formation tester （WFT） are introduced. Through cases of WFT working in Jungar and Tarim Basin, Xinjiang, described are applications of WFT in oil-gas field exploration, such as formation pressure acquirement and permeability estimation in exploration well, downhole sampling and on-site composition analysis. Compared are measurement results of WFT and drill stem testing （DST）, analyzed are causes of their differences, summarized are their applicable conditions and then pointed out is that WFT and DST should be selected for using by practical geological conditions and testing objects. Attentions for using WFT are presented. It is considered that advantages of WFT have not been fully utilized nowadays in China. Some experiences on applying WFT are presented.
