国外电缆测井技术新进展

Recent Advances in Foreign Wireline Logging Technology

介绍了国外测井公司近年来推出的电缆测井新技术以及新型或改进型测井仪器的特点、结构组成及工作参数。主要包括:新型3D电极电阻率测井仪器、新型阵列感应测井仪器、新型微电阻率极板仪器、油基泥浆成像仪器、低污染流体采样技术、新一代油管传送流体采样系统、具有椭圆形极板的地层压力测试仪器和ConneX射孔系统。这些新仪器和技术可在斜井或水平井中更准确地确定三维地层电阻率分布,改善地层评价;采集"清洁的"地层流体样品,缩短采样时间;克服常规聚能射孔系统的不足,提高油气井的产量。

Introduced are specialities, structures and parameters of some newly developed well logging tools used by eminent well logging companies in the past few years, such as the new 3-D electrode-type logging tool,the new asymmetrical array induction logging tool,the new micro-re- sistivity pad tool, the oil-based mud imaging tool, the novel through-casing resistivity tool, the for- mation tester with an oval pad, the ArmadaTM sampling system and the ConneX perforating system. These technologies and tools can be used to determine 3-D formation resistivity distribution in deviated and horizontal wells, acquire clean fluid samples in short period , overcome the deficiency of traditional perforating system and increase oil and gas production.
