Wireless encoding detonation control device

Abstract

The invention discloses a wireless encoding detonation control device which comprises a ground system and an underground system. The ground system and the underground system are connected through an oil pipe. The ground system comprises a ground controller, an air compressor and a vibration exciter, wherein the air compressor and the vibration exciter are connected with the ground controller. Theground controller is used for conducting wireless encoding parameter setting according to the construction requirement of perforation, and aerodynamic force provided by the air compressor is used forcontrolling the vibration exciter to send reliable encoding signals to the underground system through the oil pipe. The underground system comprises one or more detonation control connectors containing encoding controllers, and the multiple detonation control connectors containing the encoding controllers are connected in series underground. The encoding controllers are used for receiving encodingsignals emitted by the ground controller, carrying out corresponding detection and ignition operation according to the encoding signals, and storing the encoding signals and the temperatures. Multiple times of perforating operations can be achieved through single-trip of descending a well, the detonation transmission problem occurring in the detonation process is solved, and the on-site construction working time is greatly shortened.

Description

technical field [0001] The invention belongs to the field of oil well completion and perforation, and relates to a wireless coding detonation control device. Background technique [0002] As an important natural resource, petroleum occupies a pivotal position in the process of my country's economic and social development. 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 research and 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 oil, after the new oil we...
