电缆地层测试是求取储层流体性质、进行储层评价最为直接的方法之一[1]。地层测试评价仪(FET)是国产新一代地层测试评价仪器,不仅可以精确测量地层压力并根据压力剖面确定地层流体类型和油气水界面,而且在目的层取样时可以抽排污染流体、实时检测地层流体特性,对确定地层流体性质和分析流体成分起到了重要作用,同时它也可以计算地层渗透率,进行储层产能预测。通过在渤海油田的成功应用,简单介绍FET的基本工作原理和主要用途,重点论述其优越性和局限性,以及在渤海油田成功应用的典型实例,这对FET在其它油田的推广应用具有参考意义。

Wireline formation test is one of the most direct ways to determine the fluid properties of the target strata and evaluate reservoirs. Formation Evaluation Tool is a new homemade formation evaluation system. It can not only test the formation pressure accurately, and determine formation fluid type and gasoil-water contacts using pressure profile, but also pump the mud filtrate and monitor real time formation fluid characteristics while sampling in the target strata, which plays an important role in determining formation fluid properties and analyzing fluid components. At the same time, it can also calculate the formation per-meability and predict the productivity of the reservoirs. Through the successful application in Bohai oilfield, the principles and main purpose of FET were introduced briefly, its advantages and limitations and typical successful examples of the application were described in detail in this paper, which popularize the applica-tion of FET in other oilfields.
