Problems solved by technology

[0002] Existing inclinometers mostly adopt liquid level principle, pendent hammer principle, gyro inertial orientation principle, acceleration inclinometer principle, etc. The problem existing in existing inclinometers is that the structure is relatively complicated, and there are many error components, resulting in a large cumulative error , affecting the quality of drilling engineering
In addition, existing inclinometers have a larger frame, resulting in a smaller range of apex angle values

Abstract

The invention provides a floating hammer random oriented floating gyro inclinometer, comprising a detection tube, where a measuring room is arranged in the detection tube and supported by bearing on the outer wall of the detection tube, a potentiometer is arranged in the measuring room, insulating liquid is filled in the measuring room, and a needle brush floats in the insulating liquid in the measuring room; a locking mechanism is arranged in the measuring room and connected with the needle brush or the potentiometer to make the needle brush contact with or separated from the potentiometer. When it is placed in an oil well with a certain gradient, the needle brush is still vertical and the potentiometer inclines with the measuring room along the oil well so that the needle brush contacts with the potentiometer, so as to be able to measure the gradient (vertex angle or azimuth angle) of inclined segment of the oil well. And its structure is largely simplified, so that the measuring error is reduced.

Description

technical field [0001] The invention provides a device for measuring the inclination of an oil well, in particular to a floating hammer inclinometer with random orientation of floating weights. Background technique [0002] Existing inclinometers mostly adopt liquid level principle, pendent hammer principle, gyro inertial orientation principle, acceleration inclinometer principle, etc. The problem existing in existing inclinometers is that the structure is relatively complicated, and there are many error components, resulting in a large cumulative error , affecting the quality of drilling and measuring engineering. In addition, existing inclinometers have a larger frame, resulting in a smaller range of apex angle values. Contents of the invention [0003] The purpose of the present invention is to improve the deficiencies in the prior art, to provide a floating hammer random orientation buoy with simple structure, reliable performance, and improved accuracy, stability and...
