约束稀疏脉冲储层反演技术在Sufyan凹陷的应用
|
摘要
Sufyan凹陷深层AG组砂体存在厚度较薄、横向变化快、储层预测难度较大的问题,而约束稀疏脉冲反演作为储层预测广泛使用的方法,具有反演精度高、多解性少的特点,能够直观地刻画岩性的空间分布规律。本文运用约束稀疏脉冲储层反演技术,通过地震资料分析、测井曲线标准化处理、精细井震标定和子波提取等一系列工作,优选反演参数,对Sufyan凹陷深层AG组进行了储层预测,为该区的储层评价提供了有力支撑。实例应用表明,该技术处理后的预测效果与钻井资料区域沉积特征相吻合,能够为后续开发提供依据。
Due to the sand bodies are thinner and the lateral reservoir change seriously of deep AG member in Sufyan sag,the reservoir prediction is very difficult to do.However,the constrained sparse spike inversion is widely used for reservoir prediction in many oil fields of the world.This method has high precision and has less unknown various,and can preferably overcome the multi-answers problem.It is able to visually depict the characteristics of the spatial distribution of lithology.We used the constrained sparse spike inversion technique,through a series of work,such as the analysis of seismic data,well logging curve standardized processing,fine well-to-seismic calibration and wavelet extraction and so on,optimized inversion parameters,deep AG member in Sufyan sag has carried on the reservoir prediction,provided a strong support for the reservoir evaluation in this area.Application showed that the forecast effects after technical processing are consistent with the drilling data and the sedimentary characteristics in this area,it can provide the basis for future development.
