摘　　要：针对A油田生物礁储层内部结构复杂、油气分布不均一等问题，开展地震、测井及地质综合一体化油藏描述和评价。综合研究区钻测井、取心和地震资料，根据碳酸盐岩层序地层学和沉积学原理，通过井震资料结合搭建层序地层格架，研究生物礁沉积特征及演化过程；利用声波测井曲线重构技术开展波阻抗反演，描述有效储层展布特征；应用层序约束地震、测井和地质多学科一体化技术提高油藏描述精度，降低勘探开发决策风险，为后期开发方案的部署奠定坚实基础。Considering the complicated geological characterization of reef reservoir and the heterogeneity of oil and gas distribution, this paper puts forward a seismic, logging and geologic integrative study method for reservoir de- scription and evaluation. Based on core analysis, logging data and seismic data, the isochronous stratigraphic framework of the reef reservoir was built up according to the principles of carbonate stratigraphic sequence and sedi- mentology; then reef sedimentary characteristics and evolution were studied. By using the method of acoustic curve reconstruction, impedance inversion could reflect effective reservoirs distribution. Application of integrated tech- nique of seismic, logging and geological data is an effective method to increase reservoir description accuracy, re- duce the exploration and development risk, and guarantee the successful oilfield development.
