目前已开发的老油田，主要以构造为其主控因素，尤其复杂断裂油田，它们是目前产量构成及挖潜的主体；由此围绕控制剩余油分布的重要因素－复杂断裂油田小构造的系统研究及模式的总结具有重要意义，作者以渤海湾盆地东营凹陷中复杂断裂油田－纯化油田为例证，在三维地震理论与实际分辨率的分析研究基础上，研究总结出了复杂断裂油田小构造研究的基本模式。该成果已在老油田开发中取得了显著的增储上产效果；显然，复杂断裂油田小构造研究模式，在东部老油田的挖潜中具有参考与指导作用。
At present, the developed old oilfields are dominated mainly by tectonics, especially complex fractured oilfields, which are the main body of current production and tapping potentials. Therefore, a systematic study on the small structure of complex fractured oilfields around the important factors controlling the distribution of remaining oil And the conclusion of the model is of great significance. Based on the analysis of three-dimensional seismic theory and actual resolution, taking the complicated fractured oilfield-purification oilfield in Dongying Sag, Bohaiwan Basin as an example, this paper summarizes the research on small structures of complex fractured oil fields Basic mode. The results have achieved significant increase in yield and yield in the development of old oilfields. Obviously, the study mode of small tectonics in complex fractured oil fields has a reference and guidance in the tapping potential of the eastern oilfields.
