Example Embodiment

[0010] The present invention will be described in detail below in conjunction with the drawings and embodiments.

[0011] Such as figure 1 , And 2, the present invention includes a base frame 1, a test platform 2, a test reference 3, a fixing member 4 and a horizontal bubble 5.

[0012] The test platform 2 of the present invention is fixedly connected to the base support 1 by three adjustable screws 6, and the level of the test platform 2 can be maintained by adjusting the three adjustable screws 6. Among the three adjustable screws 6, two of them are fixed to one end of the test platform 2, and the other is fixed to the other end of the test platform 2. The test datum 3 includes three datum frames representing different well inclination angles, and the three datum frames are 0° datum frame 31, 45° datum frame 32 and 90° datum frame 33, respectively. Among them, the 90° reference frame 33 is horizontally fixed on the test platform 2 by a number of screws, which is the horizontal a...

Abstract

The invention relate to a calibration console and a calibration method of an inclinometer while drilling. The calibration console is characterized by comprising a base support, a testing platform is arranged on the base support through three adjustable screws, a testing benchmark and two spirit bubbles are arranged on the testing platform, the testing benchmark is a triangular support formed by connecting a 0-degree benchmark bracket, a 45-degree benchmark bracket and a 90-degree benchmark bracket, the 90-degree benchmark bracket is horizontally fixed on the testing platform, the 0-degree benchmark bracket is vertically fixed at one end of the 90-degree benchmark bracket arranged on the testing platform, the 45-degree benchmark bracket is connected between the 0-degree benchmark bracket and the 90-degree benchmark bracket, fixing members for fixing the inclinometer while drilling are arranged on the benchmarks, one spirit bubble is arranged on one side of the 0-degree benchmark bracket, and the other spirit bubble is arranged on one side of the 90-degree benchmark bracket. The calibration console is simple in structure and rapid to install, rapid regulation can be achieved through spirit bubble inspection and screw regulation, and a fixed standard testing angle with high precision is provided. The calibration console and the calibration method of the inclinometer while drilling can be widely applied to precision calibration processes of the inclinometer while drilling during oil drilling field measurement operation.

Description

technical field [0001] The invention relates to a calibration platform and a calibration method, in particular to a calibration platform and a calibration method of an inclinometer while drilling used for measuring well inclination in the process of oil measurement while drilling. Background technique [0002] In recent years, with the continuous development of oil drilling technology, the measurement-while-drilling and downhole steering control technology has made great progress. , tool face, resistivity, gamma, rock density, pressure, etc. However, the accuracy of measured values ​​is very important for geosteering and formation evaluation. Therefore, it is necessary to evaluate and verify the measurement accuracy of LWD tools for the design of LWD tools. The existing inclinometer while drilling uses the three-axis turntable of the inclinometer to realize the calibration of the instrument. This kind of equipment is complicated to install and cannot meet the rapid calibrat...
