Abstract
The invention relates to a manufacturing method of an insulation bearing shell of an oil well logging instrument. The traditional process is complex, and the oil can easily leak, thereby causing inconveniences to manufacture, application and maintenance. The bearing shell consists of 3 different materials. The manufacturing method comprises: winding a sub-structural tube of one third of the thickness of an overall product with high-performance fiber, injecting high-temperature epoxy adhesive through vacuum pumping, heat-curing, finishing the surface, bonding a PEEK tube or a ceramic tube with the thickness being 5mm and the sub-structural tube with a bonding agent, heat-curing the bonded structure as a whole, winding the outer surface with acid-resistant fiber to the required size, injecting the adhesive through vacuum pumping, and then heat-curing, thereby completing the manufacture of an outer structural tube. The formulation of the selected high-temperature-resistant resin is unique, and the high-temperature-resistant resin not only can satisfy the requirements for full permeation with the fiber, but also can satisfy the requirements for temperature resistance, pressure bearing and corrosion resistance. The applied forming process adopts the unique gumming method and the method of adhesive injection through vacuum pumping, the adhesive content can be controlled more accurately, and the product can be more compact.

As everyone knows, induction logging and electromagnetic wave logging instrument are the important component parts of conventional oil logging equipment, and these instruments generally all are made up of electronic circuit and probe (electrode system, coil array) two parts, and instrument probe belongs to electromechanical integration.Mostly adopt the oil pressure balancing technique at present at whole world logging community electrode system; This technology key character is: (1) moves packing and balance by the fluid of leather bag or piston formation; (2) be delivered to subsurface environment pressure on each parts of immersion oil by silicone oil in the glass fiber reinforced plastics composite material insulation crust; (3) most important member is the glass fiber reinforced plastics composite material insulation mandrel in the immersion oil, the whole members of this technical requirements performance parameter under oil immersion and down-hole high-temperature and high-pressure conditions is no more than design tolerances, thereby guarantee electronics and mechanical part operate as normal, make the overall performance of instrument reliable and stable.Though adopt the electrode system of oil pressure balancing technique to use for many years, its complex process, the easy seepage of fluid is given to make and use to keep in repair and is all brought inconvenience.
Along with the manufacturing development of composite insulating material, the various physical properties of its section bar all have lifting by a relatively large margin, when reaching certain technical level, just lay a good foundation for the above-mentioned conventional art of innovation when the toughness of section bar, rigidity, intensity, heat resisting and pressure resisting and with the adhesive property of metal.
Summary of the invention:
The purpose of this invention is to provide a kind of manufacture method that is used for the bearing shell of oil well logging instrument insulating electrode, performance such as that the bearing shell of the insulating electrode of preparation has is high temperature resistant, pressure-bearing, excellent wear resistance.
For realizing above-mentioned technical problem, technical scheme of the present invention is:
Earlier twining 1/3 of overall products thickness with high-performance fiber injects high-temp epoxy glue and is heating and curing and makes the substructure pipe by vacuumizing, PEEK tubes of material or the effective particular adhesive of ceramic materials with thickness 5mm is one with the bonding heating cure of substructure pipe again, last external surface twines remainder with oxytalan again, makes the layer structure pipe by vacuumizing the injecting glue heating cure.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
1, this bearing shell is made up of the deck of 3 kinds of different materials;
2, selected fire resistant resin glue both can satisfy with fiber and fully soak into, and can satisfy heatproof, pressure-bearing, etch-proof requirement again;
3, used moulding process uniqueness, the impregnation mode adopts the vacuumizing method injecting glue, and the control of glue content is more accurate, and product is more closely knit.
