Pressure coding detonating device and method

Abstract

The invention discloses a pressure coding detonating device and method. The pressure coding detonating device comprises a pressure sensor, a temperature sensor, a signal processing circuit, a single-chip system, a power supply circuit and a detonating circuit, wherein the pressure sensor and the temperature sensor are connected with the signal processing circuit respectively; the signal processing circuit and the power supply circuit are connected with the input end of the single-chip system; the detonating circuit is connected to the output end of the single-chip system; through arrangement of the pressure sensor, the temperature sensor and the single-chip system, the pressure sensor and the temperature sensor detect pressure and temperature signals of a perforation position of an oil-gas well in real time, and sends the acquired and amplified pressure signal and temperature signal to the single-chip system; the single-chip system compares a received pressure signal with a preset coding command of a preset perforating bullet, sends a detonating command to the detonating circuit when the pressure signal in the well is detected to be in accordance with the preset coding command and controls the detonating circuit to detonate the perforating bullet. Therefore, high-safety controllable detonation is realized.

Description

technical field [0001] The invention belongs to the field of oil well completion and perforation, and relates to a pressure coding detonation device and method. Background technique [0002] As an important natural resource, petroleum occupies a pivotal position in the process of my country's economic and social development. Since the reform and opening up, with the rapid development of my country's economic construction, the dependence on natural resources, especially oil, has become increasingly apparent. my country is a country that lacks oil, and more than half of its demand needs to be imported every year. Correspondingly, the development of petroleum instruments in our country is also at a relatively backward level in the world. Increase the development of advanced petroleum instruments and improve To improve oil production efficiency and obtain higher output is a very urgent problem facing our country's petroleum instrument workers. [0003] In the exploitation of oi...
