Design And Implementation Of 3-D Visualization Well-shaft Dynamic Monitoring System

With the improvement of exploration and development level, the more difficult exploration and development, more and more high to the requirement of engineering technology of oil and gas exploration. 3-D Visualization Technology is applied to the drilling track design and testing of 3-D Visualization Shaft Turn Visual Image Dynamic Monitoring Technology.This technology can accurately show the three-dimensional well bore structure and well bore trajectory, the real-time simulation of drilling process. In order to optimize the drilling, to speed up the exploration cycle and to improve the benefit of exploration, this technology can provide technical support. This article introduces domestic and overseas three dimensional borehole trajectory display, wellbore detection technology research and its development process. The characteristics of several typical application systems are compared in this article. It reports that the drilling site major data integrated on the wellbore trajectory of the 3-D Visualization Relevant Systems and mutual operations based on different related monitoring information are also lacking in domestic at present.Dynamic monitoring system is based on 3-D visualization wellbore development practices. Then the overall design of the system is presented. This article introduces four modules in wellbore trajectory of 3-D visualization, 3-D visualization of old well trajectory, in crash-proof scanning between the drilling well and the old well, in deviation scanning between drilling well and the Designed-well-trajectory. Functional design, module object interaction and module implements are based on these four modules. The part of module implements introduces the analysis and design of the algorithms based on drilling query and 3-D trajectory drawing, old well query and 3-D trajectory drawing, crash-proof scanning between the drilling well and the old well.This software system are implemented on the VC++6.0n platform with the OpenGL 3-D graphics library. This system can apply in the real-time display of wellbore trajectory, 3-D display of old well trajectory, deviation detection between drilling well and the Designed-well-trajectory, crash-proof detection between the drilling well and the old well. This system can provide a reference of dynamic monitoring for 3-D wellbore trajectory.
