摘　　要：MDT测试是一种高风险作业,受测试时间、电缆吸附粘卡等因素的影响,井下经常出现复杂情况,后续处理耗时长,甚至引发填井事故。为降低MDT作业粘卡风险,研制了具有强抑制性、低不溶固相、超低失水和润滑防塌性能好等优点的封闭液,可有效降低MDT测试过程中电缆粘卡的风险,现场应用取得良好的效果,值得进一步推广应用。MDT logging technology influenced by testing time, cable adhering and sticking, etc, is a high risk opera- tion, in which there are often complex downhole conditions, long subsequent processing time, even leading to filling well ae- cident. To reduce effectively the risk of cable adhering and sticking in MDT operation, a sealing fluid was developed, which has advantages of strong inhibition, low insoluble solids, ultra - low filtration, good lubrication and collapse protection, etc. The field application showed that the sealing fluid is convenient and effective.
