Problems solved by technology

The problem with all of this is that the power of the downhole actuator generally comes from the ground, but in the process of transmitting the ground power downhole, there is attenuation and interference from wellbore fluctuations. The actual downhole power has a large uncertainty, which increases the downhole control. the difficulty of

example 1

[0048] In this example, the motor may include a micro motor, the oil pump may include a micro plunger oil pump, the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve may all include a two-position two-way solenoid valve, and the first , the second sensor may comprise an electronic pressure sensor.

[0049] Such as figure 1 As shown, the hydraulic system in this example may include an oil tank 14, a micro motor 1, a micro plunger oil pump 2, four two-position two-way solenoid valves (6, 7, 8, 9), an overflow valve 5, two electronic Pressure sensors (10, 11), two oil flow outlets (12, 13). The rotor of the micro plunger oil pump 2 is connected to the micro motor 1 through the connector 3, the oil inlet of the micro plunger oil pump 2 is connected to the oil tank 14, and the oil outlet of the micro plunger oil pump 2 is divided into two ways to connect with the solenoid valve 7 and the solenoid valve respectively. The valve ...

Abstract

The invention provides an output device of a downhole operation tool. The device includes a hydraulic system and a control system, the hydraulic system includes an oil storage unit, a power unit and a first switch unit, the oil storage unit stores oil; the first end of the pipeline connecting the first switch unit and external equipment forms an oil The first end is the end of the pipeline away from the first opening and closing unit; the power unit can drive the oil in the oil storage unit to flow out and flow in the pipeline; the first opening and closing unit includes at least one valve so that the pipeline is The state of circulation or closure; the control system includes a micro-processing unit, an oil circuit opening and closing drive circuit and a power drive circuit. stop. The beneficial effects of the present invention include: providing an output device of an downhole operation tool, which provides power or flow for the downhole operation tool, improves its operation efficiency, and reduces operation risks.

Description

technical field [0001] The invention relates to the field of oil testing, in particular to an output device of a downhole operation tool. Background technique [0002] In the next two years of the "13th Five-Year Plan", we will focus on the continuous increase and stable production of Changqing Oilfield, the construction of 30 billion cubic meters of oil and gas fields in Southwest China, the project of increasing production of 50 million tons in Xinjiang, and the construction of 20 million tons of oil and gas production areas in Bohai Bay. The above-mentioned projects are further extended to the fields of "low", "deep", "sea" and "non-" oil and gas resources, and the geological engineering conditions are more complicated. The engineering difficulty and risk of operating downhole equipment through remote power transmission on the ground are getting higher and higher. Driven by the wave of informatization in the industrial field, petroleum engineering technology is also movi...
