Description
Technical field
The present invention relates to and a kind ofly reduce the method for intelligent water detector switch plunger pressure and intelligent water detector mechanical switch, belong to the mechanical switch technical field of the intelligent water detector equipment of oil field well.
Background technology
Behind oil field to development late stage, generally enter the High water cut stage.General oil well many employings multilayer cage integration excavating technology, therefore oilfield technology developing department accurately cannot obtain the detail parameters (as strata pressure, Liquid output, moisture content, temperature etc.) on a certain stratum, can not take effective technological measure for the situation on each stratum.Intelligence water detector is coordinated by process pipe string and tester, the change of formation testing pressure and production stream pressure, and combined ground detects water-cut variation, finds main product layer and high aquifer formation, thus the techniques such as shutoff are taked to high aquifer formation, improve oil recovering efficiency.Mechanical switch in intelligence water detector is wherein important executing agency, and the operating principle of mechanical switch is reciprocating-piston, is namely carried out the opening and closing of gauge tap by the reciprocating motion of piston.At present, under the piston of the mechanical switch of intelligent water detector of the prior art is often operated in hyperbaric environment, therefore, extraneous pressure (ambient pressure reaches more than the 30Mpa usually) piston to mechanical switch creates very large resistance, it can be just piston action that the motor of the mechanical switch of intelligence water detector must overcome ambient pressure to the resistance of piston, so the load of motor is very large.How to reduce the resistance suffered by piston, and can move neatly, be insoluble problem in prior art always.
Summary of the invention
The object of the invention is: provide a kind of can make piston movement by ambient pressure impact, can effectively alleviate motor load and the method for the reduction intelligence water detector switch plunger pressure of instrument reliable operation and intelligent water detector mechanical switch can be guaranteed, to overcome the deficiencies in the prior art.
The present invention is achieved in that a kind of method reducing intelligent water detector switch plunger pressure of the present invention is, O-ring seals is installed additional outside the piston bottom end of intelligent water detector and between the cell wall of the body of intelligent water detector, to make bottom the groove of piston bottom end and body jointly to form an airtight cavity, thus cut off being communicated with of piston bottom end and the intelligent water detector body external world, make the pressure in the body external world can not act on the bottom of piston, so just can greatly reduce intelligent water detector under high pressure working environment ambient pressure to the axial force of its mechanical switch piston, make the motion of piston not by the impact of ambient pressure, thus alleviate the load of intelligent water detector motor.
According to the intelligent water detector mechanical switch of one of the present invention that said method builds, comprise the body having groove, piston is provided with in the groove of body, O-ring seals is provided with, the power transmission shaft of mechanical switch of the intelligent water detector that is threaded in piston tip outside piston bottom end and between the cell wall of body.
Outside above-mentioned piston tip, be provided with drive joint, between drive joint and piston, be provided with Dynamic Seal combination cover; One end of piston cylinder is connected to outside drive joint, and the other end of piston cylinder is connected with body, and piston cylinder is provided with chute, and the alignment pin be connected on piston is housed in this chute.
Seal is provided with outside drive joint and between piston cylinder.
Owing to have employed technique scheme, the present invention installs O-ring seals additional outside piston base and between the cell wall of body, make to form bottom the groove of piston bottom end and body an airtight air chamber, thus cut off being communicated with of piston bottom end and the intelligent water detector body external world, make the pressure in the body external world can not act on the bottom of piston, so just greatly can reduce intelligent water detector ambient pressure under high pressure working environment, to the axial force of its mechanical switch piston, makes the motion of piston not by the impact of ambient pressure.The present invention operationally, intelligence water detector driven by motor drive axis time, piston can not rotate under the effect of alignment pin, can only do reciprocating linear motion under the screw drive of power transmission shaft, when the piston is moving down, owing to being configured with an airtight cavity bottom the groove of piston bottom end and body, gas in this cavity can be compressed, when piston compression gas, although certain resistance can be produced, but this resistance compared with the pressure in the external world almost negligible (such as, when the volume of air in closed cavity is compressed to 1/2 of original volume, its pressure is only 0.2Mpa, be significantly less than the pressure of extraneous 30 Mpa).So the present invention can alleviate the load of intelligent water detector motor effectively, improve the reliability of instrument work significantly.Therefore, the present invention compared with prior art, the present invention not only have can make piston movement by ambient pressure impact, can effectively alleviate motor load and effectively can improve the advantage of instrument functional reliability, but also there is the advantages such as structure is simple, cost of manufacture is low, long service life.
