复杂断块油藏精细构造解释和应用效果

Fine Structure Interpretation and Application Effect of Complex Fault-block Reservoir

贝301油田是典型的复杂断块油田,在三次处理的三维地震资料品质明显改善及地质研究的基础上,以通用的地震构造解释方法为基础,以地震解释软件的应用技巧为手段,提出断裂破碎带构造精细解释的一些方法和处理技巧。通过研究和实施,解决了断裂破碎带内众多小断层和断层组合的解释,提高了断层空间展布的合理性以及对断裂破碎带构造精细解释的效率和精度,为进一步编制开发调整方案、科学合理开发奠定了基础。

Bei301 is an exponent complex fault-block oil field. Based on triple processes of 3D seismic data quality’s obvious improvement and geologic research, using general seismic structure interpretation method, as the measure of seismic interpretation software’s application, the paper proposes some methods and process technique for fault broken belt structure’s fine interpretation . It resolves the interpretation of numerous minor faults and fault combination in fault broken belt, and improves the rationality of fault spatial distribution, the efficiency and accuracy of fine interpretation for fault broken belt structure, and establishes the basic for further research.
