井间断裂构造的计算机分析方法

井间断裂构造分析是根据测井资料,以地层分层数据为基础,利用计算机技术实现井间断裂分析的一种计算机自动分析方法.动态波形匹配算法能够很好地建立井间地层之间的对比关系,可以通过曲线拟合、特征提取、匹配代价计算等步骤,自动绘制井间地层对比的路径图解.通过对各种构造的路径图分析,总结出正断层、逆断层、不整合、同沉积断层、犁式断层和地层尖灭等34种情况下的路径图模式,提出路径图模式及相关概念.

The computerized analysis methods of structures between wells

The analysis method of structures between wells is an analysis method that is based on the data of well logs, data of strata division and computer techniques. Dynamic waveform match(DWM) may be used to correlate the stratigraphic uints between wells excellently. According the processing steps, such as piecewise line fitting, log feature extraction, match cost calculation, the path diagram can be drawn automatically. After analyzing many path diagrams of structures between wells, the 34 kinds of path modes of normal fault, reverse faults, unconformity, synsedimentary fault, listric fault and pinch out are summarized, and the exception of path modes and its relative exception are brought forward.
