精细构造研究是随着高分辨率开发地震技术和油田的深度开采而产生的。由构造应力作用形成的微幅度构造、以沉积作用为主形成的储层微型构造 ,都属于精细构造的研究范畴 ,但二者在成因、识别方法上有所差异。大庆油田在高含水开发后期 ,利用高分辨率三维开发地震技术 ,对微幅度构造进行研究 ;进而在地震剖面上 ,识别出以前不能识别的微幅度构造 ,尤其通过滑动相关、倾角扫描和关联维等方法识别井间小断层 ;利用测井资料 ,研究储层微型构造 ,又通过微型构造图和趋势面剩余分析方法 ,描述对单层的层面起伏程度和形态。这些对打井找油和剩余油研究都具有重要意义。
Fine structure research is generated with the development of high-resolution seismic techniques and deep-field oilfields. Micro-structures formed by tectonic stress and micro-structures formed mainly by sedimentation belong to the research category of fine structure. However, they differ in their causes and identification methods. In the late stage of high water cut development, Daqing Oilfield uses the high-resolution 3D seismic exploration technology to study the micro-amplitude structure. On the seismic section, the previously unrecognized micro-amplitude structures are identified, especially through sliding correlation, dip scan and correlation dimension And other methods to identify small intersections; Well logging data are used to study the micro-structure of reservoirs; and the micro-structure diagrams and trend surface residual analysis methods are used to describe the degree and shape of single-layer undulations. All of these are of great significance to the study of drilling wells and remaining oil.
