摘　　要：孔缝发育程度、充填程度和连通性是乌兰花凹陷混合花岗岩储层油气产量高低的主控因素。通过对乌兰花凹陷古生界混合花岗岩类变质岩潜山井的实物、岩矿、气测、XRD等资料进行综合分析及评价方法创新,利用实物观察法、薄片镜下观察法、全烃曲线形态法、钻时与全烃曲线叠合法、XRD填隙物识别法实现对储层的有效性评价,进而建立了基于多项录井资料的乌兰花凹陷混合花岗岩储层划分标准,在现场应用中效果良好,为后期解释评价提供了科学依据。Filling degree,and connectivity of pore⁃fissures are the main controlling factors for the oil and gas production in the mixed granite reservoirs of the Wulanhua sag.Through the comprehensive analysis and innovative evaluation methods of physical,lithological,gas survey,XRD,and other data from the Paleozoic mixed granite metamorphic rock wells in the Wulanhua sag,and the method of physical observation,slice microscope observation,total hydrocarbon curve shape,drilling time and full hydrocarbon curve superposition and XRD filling material identification are used to evaluate the effectiveness of the reservoir,and then a division standard for the mixed granite reservoirs has been established based on multiple logging data.The application of this standard in the field has yielded good results and provided a scientific basis for later interpretation and evaluation.
