摘要
为解决传统砂体建模方法资料利用不充分、模型精度较低、模型结果缺乏验证等缺点,提出了基于井距综合多类资料进行砂体建模的新方法.首先从井信息数学模拟结果、沉积微相分布、地震反演砂体预测成果与井距关系入手,建立了不同方位各类资料预测准确率与井距的关系曲线,然后在此基础上建立了不同类型信息在空间的权重场分布.最后应用权重场模型对各类信息整合得到了最终的砂体模型.将该方法应用于吉林扶余油田,通过新井验证,砂体预测符合率达80%以上,而仅用井数据模拟的砂体符合率仅为62%.结果证明,该方法原理正确,资料利用程度高,是进行砂体建模时的有效方法.
To improve conventional sand body model which utilized insufficiently data, had lower precision and required farther checking, a new method integrating various data based on different well spacing was proposed. Firstly, started with analysis of relation between well location and reliability of well modeling, facies, and seismic inversion, the relation curves were obtained at different azimuth. Secondly, based on these curves, the weight field distribution of various data was calculated. Finally, according to the weight field model different types of data were integrated and final sand body model was built. The method succeeded in application in Fuyu oil field. The predicted coincidence rate of sand by the method was up to 80%, while that by well data was 62%. The results show that the method is correct and effective to build a sand body model .
