Realization Of Field 3-D Seismic Acquisition Management Systems

This paper discusses field 3D seismic data acquisition and file management, tracing field construction flow with effective management, which includes 3D construction design, data inputting, field survey data showing, assignment building, instrument format data reading and Sinopec's data format building. The data met the Sinopec's demands can create various report forms, inquire about input data and output final results satisfying the user as well. Realization of exporting 3D exploration and development database is finished according to its demands to be shown on the screen and to be printed if necessary. One or more text files can be exported for processing and interpretation so as to improve construction efficiency and accuracy of the data.By practical application, this project has acquired the following achievements:It can directly check validity of the data by measuring data reading and 3D display for 3D field data management. It can also provide processing interpretation with terrain adjustment basis with isoline protracting. Shift report data is read directly from 3D instrument daily report with accuracy and reliability, which enhances data inputting efficiency greatly and makes three men's work per day be done in a few minutes.Combined with Sinopec's data building requirement and present field practice, a set of integrated scheme input and output was compiled with standard data, providing a favorable basis for Sinopec's database construction. Meanwhile field data can be output in any text format and standard SPS format for processing interpretation as possible as it can.This software focuses on maniple management to provide data management plan for field team, construction assignment buildup, file management, data management and production report management.This study has realized computer-assisted construction design and automatic acquisition of geophysical database information with scientific and systematic management and strict quality control for 3D exploration workflow so as to greatly enhance productivity and production quality to ensure exploration data input accurately and timely and to supply vigorous foundation for processing, interpretation and management.
