Seismic exploration wireless automatic collection system

Abstract

The present invention discloses a seismic exploration wireless automatic collection system. The system comprises a field collection node, a relay, a handheld data recovery test terminal, a centralizeddata recovery charge cabinet and a seismic data fusion processing software system. The field collection node is internally provided with a high-sensitive detector movement, the field collection nodeis electrically connected with a detector interface, the detector interface is electrically connected with the detector, the centralized data recovery charge cabinet is electrically connected with thefield collection node through an external charge and data recovery port, the field collection node is in wireless connection with the relay, and the relay is in wireless connection with the handhelddata recovery test terminal. The seismic exploration wireless automatic collection system is reasonable in design, light in weight, low in cost, high in precision, large in dynamic range, stable and reliable in seismic signal collection and digitization and convenient and rapid in installation arrangement, can achieve seamless collection in real meaning and can meet the usage requirement.

Description

technical field [0001] The invention relates to a seismic exploration acquisition system, in particular to a cable-free autonomous acquisition system for seismic exploration. Background technique [0002] Seismic instruments are the core equipment of seismic exploration, responsible for collecting and recording field seismic data. Seismic instruments are mainly divided into wired systems and wireless (node) systems. Among them, the commonly used wired systems include Sercel 428XL, Inova G3i, etc. The node system can be subdivided into three categories: real-time data return system, partial data return system, and autonomous collection system. [0003] With the increasingly complex oil and gas exploration targets and surface conditions, there are many problems in the wired system. On the one hand, the complex surface is difficult to lay out, and there are great safety risks in the laying process; on the other hand, once there is an arrangement failure, it needs to wait for p...

Problems solved by technology

[0003] With the increasingly complex oil and gas exploration targets and surface conditions, there are many problems in the wired system. On the one hand, the complex surface is difficult to lay out, and there are great safety risks in the laying process; on the other hand, once there is an arrangement failure, it needs to wait for processing Only after the construction and collection can be built; these problems directly affect the efficiency, quality and safety of construction

At the same time, the wired system is also subject to many constraints such as the number of channels, flexible observation, multi-target, continuous acquisition, etc.
