摘要:
本文以贝尔凹陷小断块油藏构造建模实践为例，针对低级序断层存在的断点组合困难、延伸距离短和落差小而难以发现和描述等问题，利用三维地震解释技术、petrel及RMS软件，对小断块油藏低级序断层特征进行深入研究，定量识别和描述了低级序断层，建立了小断块油藏精细构造模型，指导了油田中后期剩余油挖潜，且取得了好效果。
Taking structure modeling practice as an example of Beier depression small fault block reservoirs, we aim at the problems such as the existing difficult breakpoint combination, short extension distance, small falling which are difficult to find and describe and so on in the low-order faults. By using 3D seismic interpretation technology, petrel and RMS software, we further study the characteristics of small fault block reservoirs of low-order faults, then quantitatively identify and describe the low-order faults, establish its fine structure model, guide the dig of remaining oil in the middle-later period of oilfiled development and achieve good results.
