Considering the specialties of petroleum exploration surveying,the paper analyzes the contents of data collecting,discusses the structure and function of data processing system,studies the design of database management system.
The recent oil prospecting data on the sea has been used to demonstrate the epicentral position of the 1918 Nanwo earthquake according to the geological structure. And the mechanism solution of earthquake focus has been inferred by macroscopic investigating data of historical water level. The earthquake magnitude, the characteristics of aftershock sequence, the estimation of magnitude of strong aftershock and the prediction of commencement time of aftershock all have been discusscd.
Linking the reality of the land oil survey, the paper discusses introducing property management responsibility, objective and significance for deepening the reform to the oil prospecting and problems existed, puts forth the direction and measures for the reform in the oil prospecting.
The paper reviewed the application history of the measuring equipments of oil geophysical prospecting, analyzed technical reasons of eliminating a part of measuring equipments and introduced adaptive environment, precision, advantages and disadvantages as well as application prospect of available mainstream measuring equipments and auxiliary equipments.
The paper first introduced the current surveying situation of oil geophysical prospecting,then the new GPS techniques such as precise relative positioning,precise single-point positioning,network RTK and differential in general domain and application of these techniques at home and abroad and presented ideas about construction of service system in movable network GPS.
