Abstract

The invention discloses a performance testing device and a method for a petroleum drilling impact device. The testing device comprises a to-be-tested impact device, which comprises a mud pump, a sensor and a data processing unit; wherein the mud pump is connected with the liquid entrance end of the to-be-tested impact device, and by the adoption of an impact force method, the sensor is used for directly determining the impact force and the impact frequency of the to-be-tested impact device of a different model. According to the performance testing device, a mode combining the sensor and data converter is adopted, a impact force method is adopted, and the impact force and the impact frequency of the to-be-tested impact device of a different model can be directly measured; a pressure sensor can also be used for measuring the drilling liquid entrance pressure, the exit pressure, and the upper cavity pressure and the lower cavity pressure of a cylinder body, and a flow sensor is used for measuring the exit flow of the impact device. By measuring the pressure difference of a cylinder body upper cavity and a cylinder lower cavity, impact power and an impact end speed are calculated. The testing method has the advantages of accuracy, rapidness and convenience.

Description

technical field [0001] The invention belongs to the field of petroleum exploration and drilling, and in particular relates to a testing method and device for testing the performance of petroleum drilling impactors, which are mainly used for testing performance parameters such as impact force, impact frequency, impact energy, and final impact velocity of impactors. . Background technique [0002] With the deepening of exploration of oil and gas resources in our country, the application range of rotary percussion drilling technology is rapidly expanding, and the impactor is the key tool to realize rotary percussion drilling technology, and its performance directly affects the rock breaking efficiency of rotary percussion drilling. One of the most critical factors for the efficient drilling of wells. The main parameters to measure impactor performance are impact energy and impact frequency. Commonly used impactor performance testing methods mainly include: stress wave method,...
