Application Of Google Satellite Map In Seismic Exploration In Complex Surface

It is in urgent need to speed up domestic conventional and unconventional oil and gas exploration because of the imbalance between their supply and demand.However,it becomes more and more difficult for us to implement new exploration techniques such as high precision 3 d exploration and urban exploration in complex surface area.Therefore,the high quality and efficiently methods has been one of the main mission of the Secondary exploration of oil and gas and unconventional gas exploration tackle key problems.Meanwhile those methods must meet the requirements of low cost.With the research of the free Google map client from internet,we can use the high resolution Google satellite images to assist seismic data acquisition in complex area.At present,the critical achievements include:(1)comprehensively utilize related software to obtain Google maps tiles and then process them into high resolution Google satellite images;(2)Coordinate System Conversion,Geometry Fine Correction,High Precision Position Control and Range of Cutting of the satellite images of vector quantization;(3)Mark the satellite images with various information of production exploration;(4)The remarkable results of practical application in northern Jiangsu oildom and Lower Yangtze region.Through the practical application research,we fully verified the feasibility of this method:(1)Entirely replace the conventional topographic map in the Project reconnaissance and the construction of the measurement of GPS control network;Meet the requirements(2)of the survey lines layout and the indoor observation system design;(3)Ensure the cost control of the projects and improve the data's quality in complex surface area.
