Description
Technical field
The utility model relates to oil well logging instrument apparatus field, specifically a kind of glass fibre reinforced plastics casing of slim-hole array induction instrument.
Background technology
Array induction logging tool is that the situation of induced signal to downhole oil, gas-bearing formation utilizing the coil of instrument own to send detects, analyzes, judges indispensable logging equipment.Array induction instrument probe shell is the important component part of whole instrument, usually adopts high-temperature insulation glass steel material.The conventional general external diameter of high-temperature insulation glass fibre reinforced plastics casing is at about 92mm, internal diameter about 70mm, and applying working condition condition is 175 DEG C/140Mpa, 200 DEG C/170Mpa two kinds.Under such operating mode, along with the increase of oil well depth, the pressure and temperature in well is proportional increase, also contains various gas (H in well simultaneously

4/ CO
2) water, oil-base mud, crude oil etc.The requirement under this rugged environment of high-temperature insulation glass fibre reinforced plastics casing should keep good mechanical strength (stretch, bend, reverse, respectively to expansion), also will have good insulating properties.Along with the demand in current oil field, we will design a kind of external diameter 73mm, internal diameter 57mm now, simultaneously can the slim-hole array induction tool housing of heatproof 230 DEG C/175Mpa.Under this operating mode, harsher to the requirement of high-temperature insulation shell.
Suspension type that what the shell of current array induction instrument probe generally adopted is and floating type two kinds, its centre mounted type needs to get on the bus a lot of groove outside the suspension member of metal, inner side keyway that also will have screw thread and the anti-rotation mounted with instrument etc., just can support shell and connector deadweight and extraneous to pulling force, such mode is not only time-consuming, and there is a lot of hidden danger.
Summary of the invention
The purpose of this utility model is to provide a kind of high temperature resistant, high pressure, good insulating, processing simple slim-hole array induction glass fibre reinforced plastics casing, to protect instrument probe, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of HTHP slim-hole array induction glass fibre reinforced plastics casing, comprise high-temperature insulation glass steel shell and plug, the two ends arranged outside of described high-temperature insulation glass steel shell has steel bushing, pressure-bearing joint is provided with inside the two ends of described high-temperature insulation glass steel shell, O RunddichtringO and high temperature back-up ring is provided with between the inner side of described pressure-bearing joint and high-temperature insulation glass steel shell, the axle center of described high-temperature insulation glass steel shell and plug is on same straight line, described plug is arranged on the shaft core position of pressure-bearing joint, and pressure-bearing joint is arranged on plug.
As further program of the utility model: described high-temperature insulation glass steel shell and pressure-bearing joint leave gap at longitudinal direction.
As the utility model further scheme: described O RunddichtringO is arranged near the side of high-temperature insulation glass steel shell, and described high temperature back-up ring is positioned at the inner side of O RunddichtringO.
Compared with prior art, the beneficial effects of the utility model are: the utility model takes floating structure, do not need the union of metal, it is not substantially by pulling force, do not consider the tensile property of shell, greatly reduce the possibility that metal shell is pulled off, this shell processing is simple simultaneously, well avoids the hidden danger that shell is buried in process.Shell of the present invention is high temperature resistant, high pressure resistant, good insulating, processing are simple, can be widely used in the various series instrument responded to.
