Embodiment Construction

[0025] The present invention is described in further detail below in conjunction with accompanying drawing:

[0026] see Figure 1 to Figure 5 , a coded detonation control device, including a ground system and a downhole system, the ground system includes a ground monitor and a computer containing a graded perforation selection control module, and the downhole system includes a plurality of coded controllers installed in different perforators , the ground monitor is connected to the computer through a USB cable, and a plurality of encoding controllers are connected in series with the output end of the ground monitor through a single-core cable.

[0027] The hierarchical perforation selection control module is used to set perforation parameters, generate a perforation command sequence according to the set perforation parameters and transmit the perforation command sequence to the ground monitor, and receive feedback from the coding controller at the same time. The perforation ...

Abstract

The invention discloses a coding detonating control device. The device comprises a ground system and an underground system which are connected through a cable; the ground system comprises a computer and a ground monitoring instrument; the ground monitoring instrument is a special hardware device for monitoring the state of perforators at all levels as well as selecting and perforating, in order to build reliable communication while working power is supplied to the underground system; a control instruction from a computer is converted into a coding signal to be loaded to a power wire to be sent to the underground system, and then an information code fed back from the underground system is received and compiled and then sent to the computer for analyzing and processing; the underground system comprises coding controllers which are mounted in different perforators; the coding controllers receive instruction signals from the level-based perforating monitoring instrument, actuating the corresponding detection and ignition and other operations, detecting the switching state of self, coding the detection result as well as returning to the ground system; the output end is able to reliably detonate a magnetic electric detonator and an EFI detonator.

Description

technical field [0001] The invention belongs to the field of oil well completion and perforation, and relates to a 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. 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] Due to the complex geological conditi...
