基于地质模式的大庆长垣油田地震资料处理

PROCESSING OF THE SEISMIC DATA BASED ON THE GEOLOGICAL MODEL FOR DAQING PLACANTICLINE OILFIELDS

针对地震资料处理质量分析时的评价结果不直观、处理成果中的井—震不一致以及技术参数选择的多解性等问题,引入了密井网条件下形成的沉积相带图、砂体厚度图等地质成果.通过采用地震属性与地质成果相关程度的估算及多节点、分层位解释等方法实现了地震处理成果保真度的客观评价,有效地指导了地震处理技术的改进.实践证明,该方法优化了大庆长垣油田的地震资料处理流程,是提高地震资料处理质量的有效方法.

In the light of the problems of the intuitive evaluated results for the quality analysis of the seismic data processing, no consistence in the processed achievements between the wells and seismic data, multi-solutions of the technical parameter selection and so on, the following geological achievements are introduced such as the sedimentary facies belt maps, sandbody isopach figures and so forth generated in the condition of the dense well pattern. Through the correlation degree estimation between the seismic attributes and geological results, multi-node and hier- archical interpretations and so on, the objective evaluations with high fidelity for the seismic processed results are realized, thus the improvements of the seismic processing techniques are effectively guided. The practice proves that the method has optimized the work flow of the seismic data processing for Daqing Placanticline Oilfields, and become the effective method to enhance the processed quality of the seismic data.
