基于DMIS的断层三维表面形态自动检测方法研究

Research on Automatic Detection Methods of Three-dimensional Fault Surface Morphology Based on DMIS

针对断层的测量需求,利用计算机控制技术对空间曲面自动测量程序进行优化,以DMIS(Dimensional Measuring Interface Specification)为开发平台分别形成四边形键入坐标式自动检测程序和任意多边形自动检测程序,且通过所述程序完成塔里木盆地塔中26井区某断层模型表面形态的仿真,给出两种针对断层三维表面形态检测的建系方法:模型建系法和机床建系法。并将空间曲面的自动测量技术应用到断层的三维表面形态测试中,形成一套针对断层复杂表面形态的自动检测方法,使得断层的三维表面形态可以通过上述程序自动测量,且可以使用多个测头角度连续进行一次测量。该方法可以克服在传统的断层检测过程中边界不能完全衔接的问题,提高断层测量的效率和自动化程度,降低测量过程中的人为因素和后期的数据处理难度。

Based on fault measurement requirements,we optimize the automatic measurement program of the space curved surface in some domestic and foreign advanced industries,using computer control technology.Moreover,we complete a quadrangle automatic coordinate entering program and an arbitrary polygon automatic detection program based on DMIS（Dimensional Measuring Interface Specification）.In addition,we simulate the fault surface in the central Tarim Basin-26 well area using the above programs and inform two system building methods of 3D-surface morphology detection of faults：The Model Building System Method and The Machine Tool Building System Method.Subsequently,the automatic measuring technique of space surface is applied to the 3D-surface shape measurement of faults.In this way,an automatic detection method for the complex surface of the fault is formed.Thus,the 3D-surface shape of the fault can be measured automatically,and a measurement can be conducted by using multiple angles of view.This allows the boundaries of faults can be fully connected in the traditional fault detection process.This method improves the efficiency and automation degree of fault measurement as well as reduces the human factor and the difficulty of data processing in the measurement process.
