摘　　要：EFET地层评价仪是中海油在国内率先研制成功的第三代泵抽式电缆地层测试器,由于该仪器具有精密重复测压、可控正反泵抽、地层流体识别和多级流体取样等先进功能,深受用户欢迎,作业地区遍及海内外。近年来,该仪器通过中海油服的不断完善和技术升级,功能得以逐步扩充,适应性、可靠性进一步增强,本文着重介绍新仪器的性能、封隔器特点、安全模块和常规流体取样、PVT取样等新增功能,展示EFET仪器的新特点。EFET(Enhanced Formation Evaluation Tool) is the third generation wireline formation tester by function of pump through, first successfully developed by CNOOC(China National Offshore Oilfield Corporation). EFET is very popular with customers and its working area is covered both domestic and abroad, because its advanced functions such as precise repeatable pressure testing, controlled positive and negative pump through, formation liquid identification, multilevel liquid sampling and so on. In the past a few years, EFET is continuous perfected and technical updated so as to its function has been extended step by step and at the same time the adaptability and reliability are enhanced. This article mainly introduces the new EFET functions, packer characteristics, safety module and the new added functions such as general liquid sampling and PVT sampling, also will show the new characteristics of EFET.
