The invention discloses an inclinometer for coal bed gas drilling. The inclinometer comprises an outer casing, a circuit cabin, an electronic compass module, a data collection module and a storage module, wherein the outer casing is in a cylinder shape; the circuit cabin is arranged in the outer casing; the electronic compass module is arranged in the circuit cabin; a sensitive axis of the electronic compass module is parallel with the axis of the outer casing; the electronic compass module is used for measuring the drilling track of the coal bed gas drilling in real time; the data collection module is arranged in the circuit cabin, is connected with the electronic compass module, and is used for collecting measuring data from the electronic compass module; the storage module is connected with the data collection module, and is used for storing the measuring data. The inclinometer solves the technical problem that the drilling track cannot be measured in the coal bed gas drilling process of the prior art.
Description
technical field [0001] The invention relates to the technical field of coalbed methane exploration, in particular to an inclinometer suitable for coalbed methane drilling. Background technique [0002] CBM drilling belongs to directional drilling. During the drilling process, if the drilling trajectory deviates, it may cause the drilling to deviate from the target coal seam and eventually lead to drilling failure. Therefore, drilling must be carried out according to the designed trajectory. In the drilling process, in order to effectively control the drilling trajectory, it is necessary to measure the drilling trajectory, and formulate a reasonable drilling process based on the measurement results, so as to realize the correction of the drilling trajectory and ensure that the drilling direction is along the set However, there is a lack of an inclinometer suitable for coalbed methane drilling, and the drilling trajectory in the coalbed methane drilling process cannot be measu...
