Problems solved by technology

[0006] Since the wired navigation instrument of the drilling rig must obtain accurate first-hand information, and the probe of the wired navigation instrument of the drilling rig is installed inside the underground guide drill bit, it is difficult to accurately navigate the drill bit, and only two A long-distance transmission line to transmit digital signals and supply power to the probe part under the ground, and to deal with various complex interferences

Embodiment Construction

[0031] The invention consists of three parts: an underground probe part, two long-distance transmission lines, and a ground receiving control display part;

[0032] exist figure 1 Among them, the three-dimensional angular frequency azimuth measurement sensor (1) that can measure the three-dimensional azimuth angle of the underground drill bit, the temperature sensor (2) that can measure the working temperature, and the CPU data encoding that can perform A / D conversion-encoding-environmental temperature compensation Each input terminal of the group (3) is interconnected, and the CPU group (3) converts the information collected by each sensor into a digitally coded serial signal and sends it to the interconnected signal modulation circuit (4) after performing ambient temperature compensation. The circuit (4) sends the modulation signal to the long-distance signal amplification output circuit (6) interconnected with it, and the long-distance signal amplification output circuit (6...

Abstract

A wired navigator for drilling machine is composed of underground probe unit, two long-distance transmission lines and the receiving-control-displaying unit. The coded CPU data is converted to analog signals, which are transmitted to modulating amplifier and remote power supply interface. The modulated signals and electric power are transmitted to underground probe. The 3D azimuth of said probe can be measured and displayed by said receiving-control-display unit via remote power supply interface, amplifier, shaper, decoder and display.

Description

technical field [0001] The invention relates to a wired navigator for drilling rigs. In particular, it relates to an oil drilling rig and a wired navigator in the drilling rig for laying underground pipelines without digging grooves on the surface. Background technique [0002] At present, most oil drilling rigs and underground pipeline laying engineering drilling rigs in the world use the built-in drilling rig wired navigator probe of the drilling rig to detect while drilling, and use only two long-distance transmission lines to receive the drill rig wired navigator on the ground. The navigation system that controls the display part to track and direct the drilling direction of the underground drill bit is used for oil drilling and laying underground pipelines. [0003] This technology is almost blank in China. And from the technology of some foreign companies, although the precision of its voyage, depth and function can meet the operating require...
