The Research Of Geosteering-drilling Data Field Fast Visualization

Geosteering-drilling is a high-tech developed in the 1990 s, can greatly improve the formation, structure, reservoir characteristics of the judgment and the drill in the reservoir trajectory control capability, thereby improving oil drilling In case rates, drilling success rate and recovery, to increase reserves and production, drilling cost savings, economic significance. Geosteering can be integrated drilling, LWD/inclinometer, geological logging and other parameters in real time to determine and identify the current location of the geological properties of the drill floor, and timely adjustment of the drill walking in the reservoir with drilling identification reservoir, oriented features and other characteristics, has broad application market, advanced technology and an important development in complex reservoirs. Thus the forefront of technological development issues based on geosteering related technologies aspects of human-computer interaction depth study focused on solving the problem of fast visualization of geological data process-oriented field.Through the topics related to data visualization, with the content and development status relevant technical drilling geosteering data processing and other learning and summarize, and ultimately determine the main contents of this article, follow the basic steps scientific visualization gives a systematic solution and technology roadmap. Firstly, the three-dimensional seismic data, LWD data types and organizational structure of the data and the numerical reservoir simulation data processing, then the idea put forward the corresponding solutions for each module. For the three-dimensional seismic data file organization proposed texture mapping volume rendering algorithm based solutions, using bricks to reduce the visual process I / O operation; against LWD logs proposed solutions based on GDI + programs and the introduction of double- buffering mechanism, while the trajectory proposed based on 3D visualization solutions Away3 D, and according to the improved Bezier curve smoothing algorithm; for the numerical reservoir simulation processing visualization is proposed based on OpenGL solutions and the introduction of OpenMP parallel mechanism and grid block edge visual mapping mechanism. Design and implementation of these solutions through basically solved the main problems geosteering visualization, and well positioned to meet the functional requirements of rapid visualization of massive data volume for geosteering drilling technology in-depth application laid a good foundation.
