井间断层分析的研究,是油气储层地质研究的一项重要基础性工作,对油气的运移和聚集其中重要的控制作用。它是利用测井资料,以地层分层为基础,采用计算机技术实现井间断层分析的一种井间断层自动分析方法。动态波形匹配算法是本次研究采用的主要算法,它能够很好地建立井间地层之间的对比关系,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。本文在对各种构造的路径图分析的基础上,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30种情况下的路径图模式,提出路径图模式及相关概念。在大港油田的实例分析中取得了很好的效果。
The study of cross-well fault analysis is an important basic work in the study of oil and gas reservoir geology, and plays an important controlling role in the migration and accumulation of oil and gas. It is a cross-well fault automatic analysis method based on logging data and stratigraphic stratification, using computer technology to realize cross-well fault analysis. The dynamic waveform matching algorithm is the main algorithm used in this study. It can well establish the correlation between the cross-well strata and automatically draw the path of cross-well stratigraphic correlation through the steps of curve fitting, feature extraction and matching cost calculation Graphic. Based on the analysis of the path maps of various structures, this paper summarizes the path patterns of 30 normal faults, reverse faults, unconformities, synsedimentary faults, plow faults and stratigraphic extinction, and proposes the path map mode And related concepts. In the Dagang oil field example analysis achieved good results.
