Abstract

The invention discloses a high-power variable-frequency energy-saving drilling machine electric control system, which is simple in structure, facilitates adjustment of a drilling direction and is convenient to control. The high-power variable-frequency energy-saving drilling machine electric control system comprises a steering drill bit and a drilling direction controller; the drilling direction controller adopts PLC and is arranged in a control cabinet; the steering drill bit comprises a main drill bit, a centralizer, a drilling rod, a first universal joint connecting rod and a second universal joint connecting rod; an NWD while-drilling instrument is arranged at one end, near the centralizer, of the second universal joint connecting rod; steering sleeves are arranged on the outer sides of the drilling rod, the first universal joint connecting rod and the second universal joint connecting rod in a sleeving way; a rotation driving device is arranged on the first universal joint connecting rod; an angle adjusting sleeve is arranged on the first universal joint connecting rod in a sleeving way; and the angle adjusting sleeve is driven by the rotation driving device to rotate. By thehigh-power variable-frequency energy-saving drilling machine electric control system, directional drilling is convenient to realize; meanwhile, the device is simple in structure and convenient to control.

Description

technical field [0001] The invention relates to the control field of oil drilling rigs, in particular to an electric control system for high-power frequency conversion and energy-saving drilling rigs. Background technique [0002] Well-known: oil drilling rig refers to in the oil drilling, drives the drilling tool to break the rock, drills into the ground, and drills a wellbore of a specified depth for the oil or gas extraction machine to obtain oil or natural gas. A commonly used oil drilling rig is mainly composed of eight parts: power machine, transmission machine, working machine and auxiliary equipment. [0003] During the drilling process of oil drilling rigs, the drilling depth and geological conditions are different. In the process of oil exploration and development, in order to avoid insurmountable ground obstacles and increase the exposed area of ​​oil and gas layers in the wellbore to increase the production of oil wells, usually in the oil and gas layers A certa...
