The common high-temperature resistant insulating glass fiber reinforced plastic shell has the general outer diameter of about 92mm and the inner diameter of about 70mm, and the working conditions of 175 ℃/140Mpa and 200 ℃/170 Mpa. Under such conditions, as the depth of the well increases, the pressure and temperature in the well increase proportionally, while the well also contains various gases (H 2 S/CH 4 /CO 2 ) Water, oil-based mud, crude oil, etc. High temperature resistant insulating glass fiber reinforced plastic housings are required to maintain good mechanical strength (tensile, bending, torsional, expansion in all directions) and to have good insulation properties under such severe environments. Along with the current requirements of oil fields, we need to design a material with 73mm outer diameter and 57mm inner diameter, and can resist temperature at the same timeA slim hole array induction instrument housing of 230 ℃/175 Mpa. Under the working condition, the requirements on the high-temperature resistant insulating shell are more severe.
At present, a shell of an array induction instrument probe generally adopts a suspension type and a floating type, wherein the suspension type needs to be provided with a plurality of grooves on the outer side of a metal pendant, and the inner side of the suspension type needs to be provided with threads for hooking the instrument, anti-rotation key grooves and the like, so that the shell and a connecting piece can be supported, and the self weight and external tensile force can be given, so that the mode is labor-consuming and time-consuming, and a plurality of hidden dangers exist.
