摘要
断层封堵性是一个极为复杂的地质问题,它受断层的力学性质、断面承受应力状态、断层剪切带等多种地质条件制约。这里从川西龙门山断层的侧向(泥质含量)和垂向(断面压力)二方面考虑,将工程科学数值的三次样条插值和最小二乘拟合法与石油专业知识结合,建立了该地区断层封堵性的数学模型,并在Matlab6.5的环境下设计了该模型的可视化软件。运用所设计的可视化软件对川西龙门山前缘地区发育一系列近北东向的逆断层的封堵性进行了综合的定量评价,体现了很强的实用性,并了取得了可观的经济效益,给石油工作者提供了方便、快捷的信息。
Fault sealing is a very complex question in geology and it is restricted by geologic factors such as mechanics category、status of stress due to fault 、fault's shear zonation etc..In the paper,by analyzing the side aspects and uprightness aspects of fault in the Dragon Door Mountain in the west part of Sichuan province,and using thrice spline interpolation and fitting in method of the least squares as well as the knowledge of hydrocarbon exploration,we build mathematics patterns of fault sealing in the area and program on mathematics patterns under the circumstances of MATLAB6.5.Using the software,we synthetically and quantitatively evaluate the fault sealing of anti-fault in the east and west parts of development area in the Dragon Door mountain in the west of Sichuan,which embodies good practicability and economic benefit,and provides convenient shortcut information for petrolic operator.
