Abstract
The utility model discloses a testing cable for oil field downhole. The testing cable comprises a temperature measurement cable core and a plurality of pressure measurement capillary tubes, the temperature measurement cable core is characterized in that conductors wrapped with insulating layers are subjected to pair twist to form pair twist groups, wrapping layers are wrapped outside the pair twist groups, a few pairs of pair twist groups wrapped with the wrapping layers are longitudinally placed and form an inner sheath layer in an extrusion molding mode, a plurality of pressure measurement capillary tubes are distributed on the periphery of the temperature measurement cable core wrapped with the inner sheath layer, a belting layer is wrapped on the exterior of the pressure measurement capillary tubes and the cable core, and a steel sleeve is sleeved on the exterior of the belting layer. The testing cable for oil field downhole has the advantages that the temperature measurement cable core and the pressure measurement capillary tubes are combined, multi-point measurement of temperature and pressure can be performed, and accuracy of information of the downhole temperature, pressure and the like can be effectively improved.
