Problems solved by technology

[0004] When the mud positive pulse generator works underground, it is in a high-temperature and vibrating environment, and its peripheral parts (referring to the rotor assembly) are washed by the mud to generate high-speed rotation. The current mud positive pulse generator test equipment can test its mechanical properties. , but the downhole environment cannot be completely and reasonably simulated, which affects the test effect

Embodiment Construction

[0022] The pulse generator test bench of the present invention consists of three parts: a temperature-controlled heating system 1 , a mechanical property test system 3 and an electromagnetic vibration system 5 . The temperature control heating system 1 and the electromagnetic vibration system 5 respectively simulate the high temperature and vibration environment of the mud positive pulse generator working in the underground; the mechanical performance test system 3 simulates the rotation of the peripheral parts of the mud positive pulse generator when it is washed by the mud, and at the same time Send a trigger signal to the pulse generator, and measure the voltage, current, and displacement signals generated by the pulse generator under the simulated environment and given signal.

[0023] Such as figure 1 As shown, the temperature-controlled heating system 1 is composed of a heating device 11 , a heat preservation furnace body 12 and a temperature control device, wherein the ...

Abstract

The slurry positive pulse generator test equipment includes mechanical performance test system, heating system and vibration system. The heating system includes one heater and one heat insulating furnace with door. The mechanical performance test system is fixed on the vibration part of the vibration system and the combination may be set into the heat insulating furnace. The test equipment of the present invention can simulate the vibration, high temperature and other environment conditions of the pulse generator under well, simulate the rotation the pulse generator peripheral generates under slurry scouring, and determine the performance parameters, so as to evaluate the performance and eliminate underproof pulse generator product.

Description

technical field [0001] The invention relates to a measurement and test equipment, in particular to a test and measurement equipment for simulating the working environment of a mud positive pulse generator in a well. Background technique [0002] Mud positive pulse generator is a key instrument for oil measurement while drilling and real-time upload of logging while drilling data. In actual work, the mud from the drill string drives the turbine blade rotor assembly to rotate at high speed. The rotor assembly is equipped with a magnet group. When rotating, it drives the magnetic shaft with the corresponding magnet group in the outer cylinder of the positive pulse generator to rotate. One end of the magnetic shaft is The swash plate of the plunger pump, the rotation of the swash plate can drive the plunger of the plunger pump to reciprocate alternately to realize the work of the plunger pump. Normally, the control valve is in the open state, and the plunger pump is in the no-l...
