Embodiment 1

[0034] Embodiment 1. Downhole perforator completion multi-parameter real-time monitoring method

[0035] The technical solution of the downhole perforator completion multi-parameter real-time monitoring method in this case first adopts the storage test technology. The pressure parameters, temperature parameters, especially the pressure parameters in the perforator and the acceleration data of the perforator itself are monitored at the same time. Secondly, the high temperature curing technology is adopted to solidify the circuit into a module, which improves the reliability of the circuit under high temperature, explosion and other shock conditions in the mine. The real-time monitoring method in this example is to use the monitoring instrument inside the perforator and the monitoring instrument outside the perforator to monitor and work together at the same time. After real-time processing of monitoring data and real-time storage of monitoring information, the perforation or comp...

Abstract

The invention relates to a multi-parameter real-condition monitoring method for well completion of an underground perforator, belonging to the technical field of underground measurement of petroleum, natural gas and the like. Aiming at severe environments such as high temperature, high pressure and high impact and the like in the process of well completion of the perforator, a monitoring instrument of the underground perforator and a monitoring instrument outside the perforator are specially researched by utilizing the method, and are leading instruments with innovative design and independent invention; and testers inside and outside the underground perforator are used for monitoring simultaneously, and processing monitored data in real time so as to obtain multiple parameters of real conditions of the underground well completion effect in perforation or/and fracture: internal pressure of the perforator, the external annular pressure of the perforator, self impact acceleration of the perforator, ambient temperature in perforation or/and fracture and the like. By utilizing the method, the high and new technologies such as variable-frequency sampling, digital processing, sensor, microminiature, micropower consumption, high temperature resistance, high pressure resistance, high impact resistance and the like are integrated, the technological content is high, the functions are strong, the performance is good, the design is advanced, the structure is reasonable, and in addition, the multi-parameter real-condition monitoring method is precise, stable, reliable and practical and has values for promotion and use.

Description

1. Technical field [0001] The multi-parameter real-time monitoring method of downhole perforator well completion disclosed by the present invention belongs to the field of downhole measurement technology of petroleum, natural gas, coal bed methane, etc., and specifically relates to a kind of downhole perforator testing during perforation or / and high-energy gas fracturing A multi-parameter real-time monitoring method for its completion effect. 2. Background technology [0002] Perforating and fracturing are among the major completion processes that open up reservoirs to allow formation fluids to flow into the well. Whether the perforation fracturing process is reasonable or not directly affects the level of oil production and the safety of perforation operations. The perforating bombs and fracturing charges used in perforating devices and high-energy gas fracturing contain high-energy materials such as explosives and gunpowder. If the formula, process and detonation sequence...
