Abstract

The invention relates to the technical field of multi-coal seam coalbed methane exploration and development, in particular to a multi-functional drilling rig suitable for coalbed methane exploration and development under multi-coal seam conditions, including a body, one end of the body is horizontally installed with a support plate, and the support plate is far away from One end of the body is vertically provided with a positioning mechanism, and the inside of the positioning mechanism is provided with a drilling mechanism. The drilling mechanism includes a vertically arranged drilling tube, and the bottom end of the drilling tube is provided with drilling teeth. The drilling tube and the positioning mechanism are connected by a driving mechanism, and a second motor is fixedly installed on the top of the drilling tube, the output shaft of the second motor passes through the drilling tube and the end is vertically connected with a rotating shaft, A helical blade is fixedly installed on the outer side of the rotating shaft, a crushing mechanism is installed at the bottom of the rotating shaft below the helical blade, and a material driving mechanism is arranged at the top of the helical blade. The drilling effect of the invention is stable, and at the same time, it has the function of fast and effective coring, which ensures the accuracy of coring.

Description

technical field [0001] The invention relates to the field of exploration and development of coalbed methane with multiple coal seams, in particular to a multifunctional drilling rig suitable for exploration and development of coalbed methane under conditions of multiple coal seams. Background technique [0002] Coalbed methane is an unconventional natural gas resource stored in coalbeds, and it belongs to a very high-quality and clean coal mine associated resource. The occurrence of coalbed methane is affected by conditions such as paleostructure, paleogeography and paleoclimate. In the process of CBM exploration, sampling analysis and testing of the target coal seam are usually used, especially the adsorption / desorption experiments of coal samples are used to analyze and study the coalbed methane resources and scientifically guide the exploration and development of coalbed methane. [0003] my country has abundant coalbed methane resources, and now the Qinshui Basin and th...
