摘　　要：电缆式地层测试资料在计算流体密度、确定油、气、水界面方面有着重要作用,但其在低孔渗地层测压点经常出现超压、致密点等现象,造成地层恢复压力偏高或偏低,使流体密度难于求取。本文通过对渤海地区多口井地层测试压力点进行分析,将测压点分为可用点、不可用点、一般点三类,找出测压点用于流体密度计算的流度范围,为渤海地区疑难层地层流体性质评价工作提供评价依据。Wireline formation test data play an important role in calculating fluid density,determining oil,gas and water interface.But superpressure and tight point often occur in low porosity and permeability formation pressure tapping point,which makes formation recover pressure high or low and it is difficult to calculate fluid density.Through analysis of formation test pressure point of several wells in Bohai area,pressure tapping points can be divided into three kinds:available points,unavailable points and general points.Finding out pressure tapping points used in fluid density calculation can provide basis for formation fluid property evaluation in difficult reservoirs.
