Description

Technical Field

[0001] This invention relates to the field of unconventional oil and gas well cable delivery cluster perforation and bridge plug integration technology, and particularly to an integrated module for initiation and control. Background Technology

[0002] With the deepening development of unconventional resources such as shale gas in China, the combined technology of cable-driven clustered perforations and bridge plugs is becoming increasingly sophisticated. In the past year, dense clustered perforation bridge plug technology with more than 7 clusters has been gradually adopted in shale gas reservoirs, achieving good results in volumetric fracturing.

[0003] However, traditional pump-driven bridge plug perforator assembly requires assembling the perforating gun, cartridge holder, perforating cartridge, detonating cord, communication lines, control module, detonator, and connecting components together. This involves numerous components, complex assembly processes, a large on-site workload, and lengthy preparation time. Especially in construction areas like Northwest, Northeast, and Shanxi, where winter temperatures are low, and in the humid and rainy Sichuan-Chongqing region, where summer temperatures are high, the harsh working environment negatively impacts assembly quality and construction success rate, and poses potential engineering quality risks. Furthermore, the complex construction environment, coupled with cross-operations such as fracturing, gas testing, and even drilling, not only results in slow coordination but also poses significant safety hazards due to prolonged on-site preparation. Therefore, it is necessary to improve the tools for clustered perforations and bridge plugs through modular design.

[0004] Therefore, how to provide an integrated module for detonation and control that solves the above-mentioned technical problems is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

The first step is embedded with a metal conductive ring that contacts and conducts with the input contact assembly. The metal conductive ring is provided with a first metal contact that passes through the isolation disk. The first metal contact is connected to the input end of the coding switch.

[0013] Preferably, the second end of the isolation plate is provided with a detonation-transmitting fixing post for mounting the fixing sleeve. The detonation-transmitting fixing post, the fixing sleeve, and the detonator are adjacent to the first notch.

When the detonation and control integrated module is used in conjunction with the modular components of other clustered perforation and bridge plug tools, the left end is connected to the previous cluster of perforation guns, and the right end is connected to the next cluster of perforation guns. At this time, the contact of the previous cluster of perforation guns is in contact with the input contact component 3 and conduction, and the contact of the next cluster of perforation guns is in contact with the output contact sealing component 4 and conduction, so that the input of the encoding switch 7 is conducted at the left end, the output of the encoding switch 7 is conducted at the right end, the encoding switch 7 and the detonator 6 are conducted, and detonation and control are realized through the encoding switch 7 and the detonator 6 and the above-mentioned conduction relationship.
