Full-automatic seismic exploration digital signal remote detonation system and remote detonation method thereof

Abstract

The present invention relates to a full-automatic seismic digital signal remote detonation system and remote detonation method. The system comprises a signal transmitting end and at least one end signal receiving end; the signal transmitting end includes a seismometer, an encoder and a central control unit; the signal output end of the seismometer and the signal output end of the central control unit are connected with the signal input ends of the encoder respectively; the signal receiving end comprises a decoder, a wellhead detector and a detonating element; the signal output ends of the decoder are connected with the signal input end of the wellhead detector and the signal input end of the detonating element respectively; and the signal end of the encoder and the signal end of the decoder are connected with each other through a wireless communication module. According to the method, remote detonation can be realized through a wireless communication mode, and protective measures such as mechanical pushing elements and digital signal multi-level verification are adopted, so that detonation of explosives which is caused by misoperation can be effectively reduced. With the full-automatic seismic exploration digital signal remote detonation system and remote detonation method thereof of the invention adopted, the safety coefficient of construction personnel and the work efficiency of explosive sources can be improved, and high-precision synchronous control and digitization and miniaturization of equipment can be realize.

Description

technical field [0001] The invention relates to an explosive detonation system in the field of seismic exploration, in particular to a fully automatic seismic exploration digital signal remote detonation system and a remote detonation method thereof. Background technique [0002] From the 1960s to the present, explosives are often used as the main seismic source in seismic exploration. The explosive seismic source has enough energy, and it has been proved by practice that it can achieve good results in oil and gas exploration. [0003] In petroleum exploration, the seismic reflection method is mainly used to find out the structural form of the strata in the depth range of several kilometers underground. Seismic waves start from the source, travel to the target layer underground, and then return to the ground. To travel such long distances, a sufficiently powerful source must be used to generate seismic waves. In addition, it should be pointed out that various waves, such ...
