The invention discloses a perforation intelligent detonation method and device, and a perforation intelligent detonation water oil well, wherein the perforation intelligent detonation method includes: sending a detonation signal; several detonation mechanisms respectively receiving the detonation signal, and according to the The detonating signal determines the mechanism to be detonated from the plurality of detonating mechanisms; according to the detonating signal, the mechanism to be detonated is controlled to detonate, and then the perforating gun performs perforation; wherein, the detonating signal is a wireless signal; It solves the problems that the current conventional perforation initiation technology has high cost and cannot meet the technical requirements of special wells.
Description
technical field [0001] The invention relates to the field of perforation detonation, in particular to a perforation intelligent detonation method and device, and a perforation intelligent detonation water oil well. Background technique [0002] In recent years, with the increasingly stringent safety and environmental protection situation in oilfields, the application scope and scale of tubing-transported perforation have been increasing year by year due to its easy well control. Compared with wireline conveyed perforation, the cost of tubing conveyed perforation has increased significantly, which is mainly reflected in the cost of detonating equipment and auxiliary equipment. At present, the detonating equipment used in tubing-transported perforating mainly includes detonating devices, delay devices, safety devices, detonators (detonators), delay tubes and other pyrotechnics, and these devices are disposable consumables. Wherein the detonating device is an ignition mechanis...
