Application Study Of GPS-RTK Technology In Petroleum Geophysical Exploration

Petroleum exploration is a systematic project, it requires measuringtechnology to provide the accurate position of accept point, shot point,measuring the horizontal coordinates and elevation of thesurface of earth accurately, measuring technology gives thenecessary basic data for seismic data interpretation. So geophysicalmeasurment in oil geophysical exploration has played a "vanguard" and"staff" role. It is a difficult task and responsibility.on the basis of experience in the field many years, with the realmeasured results as the main data source,This article introduces thegeophysical measurement technology,completes the description andpromotion of the GPS-RTK fieldworking method in petroleum explorationand the theory of the new point lofting technology. describes in detailin the development train of thought and working method of software ofthe geophysical prospecting process and geophysical survey work。 Putsforward a set of work area, which based on the work of surveying andmapping technology advanced, seeking truth from the facts and theorywith the actual construction practice.give a way of how to give seismicprospector a comprehensive, precise measuring results to fill hisrequirements. with database technology support,it makes an integrateddesigned, functional module, Establishs an data processing softwaresystem on multipurpose of processing, output, the integration,gives amultifunction of the technical requirements, to achieve a cross on themeasuring data processing technology. Finally, it summarize the wholegeophysical measurements, enhance the accuracy and completeness of themeasurement data, builds a quality management system of point lofting,data processing, data collect, data evaluation and other aspectsconstruction factors as the object of work method, purpose andfeasibility.Through the above research, it gives the following results:1． It summarized the current geophysical measurement method andprocess technology, formed a set of GPS-RTK technology rapid, preciselofting exploration work method of physical points, provide thetechnical reference on measurements for future large three-dimensionalfield scales of oil and gas exploration. 2． Through the analysis of case, This paper completes thecontrastive analysis of the results obtained from the network RTKtechnology and the conventional RTK technology and gives thefeasibility study on how to apply the network RTK technology in petroleumexploration surveying.3． through the analysis of the measured results of the coordinatedata. It summarizes the characteristics of petroleum explorationphysics point data, give clear vision about the seismic prospectorrequirement of survey data. And on this basis,it writes a clear logicsteps, a high degree of automation of the measurement datapost-processing software in the industry...
