摘要:
为解决轮南油田三叠系T油组砂体较薄、岩性横向变化大、单纯的声波测井曲线不能有效的反映储层特征、岩性勘探开发尚未取得实质性进展等问题,采用基于模型的拟声波反演方法,以岩石物理学为理论指导,从地质分析入手,综合地震和测井资料,优选出对储层特征比较敏感的自然电位曲线,结合原始声波曲线构建能反映储层横向变化的拟声波曲线,开展了基于模型的测井约束反演。结果表明:拟声波反演比原始声波反演效果好,分辨率提高,在密井网区纵向分辨率可达3~5 m,反演结果相对误差为0.26%~24.49%,平均相对误差为13.7%,可以基本满足薄砂体雕刻的需要,拟声波反演技术对薄砂体的预测取得了一定的效果。
Abstract:
In order to solve the problems in T oil group of Lunnan Oilfield which demonstrate thin sand body and big lateral variations of lithology,pure acoustic logging curve do not reflecting reservoir characteristics,lithological exploration and development has not yet been achieved substantial progress,using pseudo acoustic inversion method based on model,guided by rock physics theory,starting from the analysis of geological with seismic and logging data,SP curve is selected which is more sensitive to reservoir characteristics.And pseudo acoustic curve is constructed which can reflect the lateral variation of reservoir with original acoustic curve,then carries out the logging constrained inversion based on model.The result shows:the prediction of acoustic inversion technique for thin sand body has a better effect than original acoustic curve with enhanced resolution.The inversion vertical resolution can reach 3~5 m in dense well area,and the relative error of inversion results is 0.26%~24.49%,the average value is 13.7%,it can basically meet demand of carving of thin sand body.The prediction of acoustic inversion technique for thin sand body has a good effect.
