Technical support for equipment for continuous acquisition operations and saturation excitation
As the center of gravity of oil and gas exploration and development continues to shift to deep-ultra-deep layers and more complex fields with strong complexity of the surface.the requirements for seismic explora-tion acquisition equipment have also increased,especially the amount of equipment invested in a single three-di-mensional project has increased rapidly from more than 10000 channels 10 years ago to 70000 to 80000,or even 100000 channels,and the number of equipment applied to a project in the Middle East for production acquisition is close to 240000 channels.Under the same failure rate,the proliferation of equipment base brings about the in-creasing number of failures and standby time,which is even more unable to meet the daily efficiency requirements of various efficient acquisition.The project operation unit expects to devote more construction time to stimulated acquisition,so the requirements put forward to the acquisition system is to stimulate the acquisition of other work,such as testing,troubleshooting and so on,to complete"backgrounding",and ultimately realize the con-tinuous operation of the seismic exploration and acquisition.This paper introduces some ways for mainstream seismic instrument manufacturers to realize background operation for technicians'reference.
