针对河流相储层厚度薄,横向变化大,预测难度大的特点,通过对测井曲线进行精细的处理和解释,包括深度校正、环境校正、标准化、曲线重构、测井与地震结合的地层对比与测井约束反演技术有机地结合,提高了测井约束地震反演的可靠性,确保了在地震储层描述中所用测井资料的精度和储层预测的准确性。将测井曲线精细处理解释技术应用于胜利油田樊东地区沙二段河流相沉积砂体的识别,取得了很好的效果。

Fluvial reservoirs are thin in thickness and rapid in lateral variations, leading to difficulty to predict. Based on meticulous logging data processing through depth correction, environmental correction, normalization, curve reconstruction, and correlation between seismic and logging data, log constrained seismic inversion is implemented. Desired results have achieved in the characterization of fluvial sand reservoirs of the second segment of Sha Formation in Fandong area.
