成像测井技术在塔巴庙地区的应用

利用核磁共振和声电成像测井新技术结合常规测井资料,可得到地层岩石和流体的信息,对这些信息的综合分析,有助于对钻遇地层的特征和含油气性做出正确判断。在塔巴庙地区,针对目的层系致密砂岩和碳酸盐岩等复杂储层,应用核磁共振和成像技术结合常规资料,开展了气层识别、沉积相、地应力、裂缝识别分析等几方面的测井评价工作,应用成果表明测井解释精度和符合率得到提高,地质效果良好,已在整个探区推广应用。

Application of imaging log at Tabamiao area

The information of rocks and fluids is available by utili- zing the integrated techniques of the nuclear magnetic reso- nance(NMR)log,the acoustic and electric image log and conventional logging methods.The overall analysis on the data is helpful to make a right decision on the borehole for- mation characters and whether oil and gas are contained. The NMR log and imaging technique are combined with con- ventional logging data to identify the gas horizon,sedimenta- ry facies,ground stress and fissure in the complex reservoirs as compact sandstone and carbonatite.The results of appli- cation suggest that the accuracy and coincidence rate of log- ging interpretation are highly enhanced.
