A drilling rig for oil exploration

Abstract

The invention relates to drilling equipment for oil exploration and with a good heat dissipation effect. The drilling equipment comprises two vertical columns, a fixed rod horizontally arranged between the two vertical columns, and a drilling mechanism arranged on the fixed rod. Auxiliary fixing mechanisms are arranged under the vertical columns. In the drilling equipment for oil exploration and with the good heat dissipation effect, guide sleeve pipes are arranged under the vertical columns in a sleeving mode, and then supporting of the vertical columns is achieved through a horizontal fulcrum bar and a fixed column. When relative displacement occurs to the guide sleeve pipes and the vertical columns, due to the fact that the teeth on a strip-shaped tooth mesh with a driving gear, rotation of the driving gear is achieved, heat dissipation of a heat dissipation fan to a motor is controlled, and the heat dissipation effect of the drilling equipment is improved. In addition, in a work power circuit, the characteristics that a transformer core is high in use ratio, power voltage is high in use ratio, output power is large, base electrodes of two triodes are both low levels, and a driving circuit is simple are achieved, and thus the practical value of the drilling equipment is increased greatly.

Description

technical field [0001] The invention relates to a drilling rig for oil exploration. Background technique [0002] The so-called oil exploration is to find and ascertain oil and gas resources, and use various exploration methods to understand the underground geological conditions, understand the conditions of oil generation, oil storage, oil and gas migration, accumulation, preservation, etc., comprehensively evaluate oil and gas prospects, and determine oil and gas resources. Gather favorable areas, find traps for oil and gas storage, ascertain the area of ​​oil and gas fields, find out the situation of oil and gas layers and the process of production capacity, and increase crude oil reserves and related oil and gas products for the country. [0003] In the existing oil exploration process, the area needs to be drilled. The existing drilling equipment needs external auxiliary brackets to stabilize it during the work process to ensure the reliability of the drilling. However,...

Problems solved by technology

[0003] In the existing oil exploration process, the area needs to be drilled. The existing drilling equipment needs external auxiliary brackets to stabilize it during the work process to ensure the reliability of the drilling. However, due to long-term work, The motor will overheat, thereby reducing the service life of the motor; not only that, but in the process of equipment work, the driving circuit of its working power circuit is complicated, and the defect of low output power reduces the practical value of drilling equipment
