Embodiment Construction

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

[0011] as attached figure 1 As shown, the probe test device consists of a wheel 1, a base 2, an adjustment handle 3, a rail fixing base 4, a target probe 5, an azimuth adjustment mechanism fixed disk 6, an azimuth adjustment mechanism rotating disk 7, a guide rail 8, and a probe clamp Tightening device 9, pitch adjustment mechanism fixed disk 10, height adjustment mechanism 11, handwheel 12, pitch adjustment mechanism rotating disk 13, and adjustment foot 14 forms.

[0012] The wheel 1, the adjustment handle 3 and the adjustable foot 14 are mounted on the base 2 to form a mobile platform for the probe testing device. The wheel 1 is used to move the probe test device. There are 3 adjustable handles 3 and 3 adjustable feet 6 to form a plane for fixing the probe test device and level adjustment; the guide rail 8 is installed on the base through the guide rail f...

Abstract

The invention relates to a searching tube testing device for testing the measuring accuracy, algorithm accuracy and direction of a target searching tube in drilling engineering. The searching tube testing device comprises wheels, a base, an adjusting handle, a guide rail fixing base, the target searching tube, a direction adjusting mechanism fixing disk, a direction adjusting mechanism rotating disk, a guide rail, a searching tube clamping device, a pitching adjusting mechanism fixing disk, a height adjusting mechanism, a hand wheel, a pitching adjusting mechanism rotating disk and an adjusting bottom foot, wherein the height adjusting mechanism is arranged on the guide rail, and is connected with the pitching adjusting mechanism fixing disk; the pitching adjusting mechanism rotating disk is arranged on the pitching adjusting mechanism fixing disk; one end of the direction adjusting mechanism fixing disk is connected with the height adjusting mechanism, and the other end of the direction adjusting mechanism fixing disk is connected with the pitching adjusting mechanism rotating disk; and the direction adjusting mechanism rotating disk and the searching tube clamping device are arranged on the direction adjusting mechanism fixing disk. The searching tube testing device is made of a non-magnetic material, does not have magnetic field interference on the target searching tube, and is used for testing the measuring accuracy on a magnetic field and the algorithm accuracy of the target searching tube in different space states and determining the direction of the target searching tube when the target searching tube works.

Description

technical field [0001] The invention relates to a probe test device used in drilling engineering for testing the measurement accuracy, algorithm accuracy and prescribed position of a target probe. Background technique [0002] With the rapid development of modern oil and gas exploration and development, complex structure wells have become the frontier and key of the international oil industry in the 21st century. Modern geometric steering drilling technology has made great progress in recent years to meet the needs of complex structure wells, but it is still difficult to meet the requirements of high reliability, high precision and anti-interference. On the other hand, in order to alleviate my country's energy shortage, the coalbed methane industry has received widespread attention from the society. However, the industry is still in the period of exploration and development, and one of the reasons for the slow development of the industry is the lack of core technologies for...
