The real-time active shot point trigger control system for seismic exploration under water conditions has the advantages that high-precision dynamic coordinate data can be collected according to the GPS, the data can be analyzed and calculated in real time, the shot points can be accurately positioned according to the designed position, and the shot distance can be accurately controlled.
Description
Technical field
The utility model relates to ocean and inland river etc. on a large scale under water area condition, in departments such as engineering exploration, geologic examination, petroleum prospecting, metallurgical exploration, oceanographic surveys in artificial earthquake investigation and prospecting, when need to according to design shot point coordinate and shot interval, automatically provide trigger pip and control Seismic Source System, be specifically related to the real-time initiatively Triggering Control System of seismic prospecting shot point under a kind of water area condition.
Background technology
Development along with economic construction, the energy is along with exploitation constantly reduces by land, the cry utilizing for marine resources development is also more and more higher, more and more relates to the water areas projects such as rivers, ocean (harbour, harbour, bridge spanning the sea, tunnel, submarine optical fiber cable, gas pipe line etc.) and will drop into planning and design and construction; In each stages such as the feasibility study developing at water areas project and water area resource, design and construction, all be unable to do without geologic prospect work.Waters seismic prospecting is that waters geologic prospect is commonly used and cost-effective a kind of means the most.
Yet, more in waters two dimension reflection wave seismic prospecting process both at home and abroad is at present the navigator fix of " passive " formula, utilize GPS (GPS) to instruct Seismic Operation ship along the survey line navigation of setting, record flight path and by certain time interval (as 1s, 2s ... Deng) or control manually and trigger focus, record the survey line position of shot point, can not design degree of covering accurately by seismic acquisition configuration and control and trigger focus with the shot interval of fixing.
During reflection wave seismic prospecting, the accurate control of the accurate location of shot point and shot interval is very important, and this is the prerequisite of determining accurate degree of covering, is that reflection wave data is processed the parameter that must know while extracting road collection.Only had shot point location and shot interval accurately just to have the accurate playback of reflection wave stacked section, the Geological Achievements of seismic data interpretation just can have geographic position accurately.
For this reason, in waters two-dimension earthquake exploration in the past, we have taked many artificial measureses (as kept as much as possible ship headway consistent on a survey line, and attempt in navascreen, survey line to be set at a certain distance, treat that near shipping agency to manual triggers set point blows out), but this is very difficult and precision is very poor.
The practice of long-term waters seismic prospecting shows: the difficulty of dynamic (RTK) location technology to the accurate location of waters seismic prospecting shot point and the processing of the accurate control of shot interval reduction data greatly during research and utilization high-precision real, improve the precision of exploration, and will improve the work efficiency of waters seismic prospecting.
Summary of the invention
The purpose of this utility model is to provide the real-time initiatively Triggering Control System of seismic prospecting shot point under a kind of water area condition, can accurately control the accurate location of shot point in the seismic prospecting of waters and shot interval.
For achieving the above object, the technical solution adopted in the utility model is: the real-time initiatively Triggering Control System of seismic prospecting shot point under a kind of water area condition, it is characterized in that this system comprises main control module, the input end of described main control module is connected with GPS inclinometer, and the output terminal of described main control module is connected with PLC.Described system also comprises a logging modle, and this logging modle is connected with main control module.Described system also comprises display module, and described display module is connected with main control module.Described system also comprises a communication module, and main control module is connected with GPS inclinometer, display module and logging modle by this communication module.Described communication module is RS-232 serial ports.
By communication module, gather GPS and inclinometer data and give main control module and display module data.The distance of main control module zequin and current point coordinate, if the shotpoint spacing of meet setting from, send trigger pip to PLC, and record current shot point coordinate by logging modle.Therefore, the utility model has the advantage of the Dynamic High-accuracy coordinate data that can gather according to GPS, and real-time analysis computational data, by design attitude, accurately locate shot point and accurately control shot interval.Through field demonstration repeatedly, utilize the real-time initiatively Triggering Control System of seismic prospecting shot point under water area condition, by control manually, change instrument into and initiatively trigger focus, time advance or delay that field operation focus triggers have been dwindled, improve waters artificial earthquake work efficiency and reach 20%～30%, the difficulty of simultaneously industry data in greatly reducing being processed, improves exploration results precision.
