Problems solved by technology

At present, before the air hammer enters the well, the air injection test is usually carried out on the drilling floor, and only the vibration and sound are used to judge whether the working state is normal. This is an empirical evaluation, and there are many uncertainties

Abstract

The invention relates to the technical field of drilling equipment, in particular to a method for testing a gas drilling impact power tool, which comprises the following steps of: installing a rack device, arranging a data processing system, arranging a signal acquisition unit in the data processing system in a tailstock assembly of the rack device, a to-be-tested tool is installed in the rack device for testing operation, the data processing unit processes corresponding logical operation of corresponding data signals, and finally the impact force, impact energy and impact frequency of the to-be-tested tool are obtained and displayed in real time. According to the technical scheme, the rack device provided with the signal acquisition unit is adopted, the impact force, the impact energy and the impact frequency of the gas drilling impact power tool are quantitatively tested, measured parameters are acquired and analyzed, and evaluation, analysis and improvement of the gas drilling impact power tool in the later test period are facilitated.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a test method for a gas drilling impact power tool. Background technique [0002] At present, domestic oil and gas well drilling has higher and higher requirements for drilling speed. In the process of gas drilling, the effect of gas weight on the wellbore is negligible. Affected by the action of the overlying strata, the stress state of the rock formation at the bottom of the well changes from compressive stress to tensile stress. Therefore, compared with conventional mud drilling, gas drilling has a significant speed-up effect. In addition, gas drilling also has great advantages in leak prevention and reservoir protection. The basic principle of gas drilling impact power tools represented by air hammer is to change the flow channel of high-pressure gas in the tool, drive the piston to reciprocate up and down, and impact the bit at a certain frequency, forming an imp...
