哈里伯顿公司推出一种经过现场试验的新仪器——油基泥浆随钻成像测井仪OBM(Oil-based-mud Imager)。该仪器集成了微电极和超声脉冲回波声波成像测井技术各自的优点于一体,如声波成像测井对井眼不规则度有较高的灵敏度;微电阻率成像测井对岩性、层理、倾角、沉积结构和流体界面有较高的像素分辨率 Halliburton introduced OBM (Oil-based-mud Imager), an oil-based mud-boring, imaging-ready logging tool. The instrument integrates the advantages of microelectrode and ultrasonic pulse echo acoustic imaging logging technology, such as acoustic imaging logging for high sensitivity to borehole irregularities; micro-resistivity imaging logging for lithology, layer Tilt, dip, sedimentary structures and fluid interfaces have higher pixel resolution
