摘　　要：礁滩型碳酸盐岩油藏因储层发育受沉积环境及后期改造等多种因素制约,在开发过程中面临多种挑战。以Sapinhoa大型礁滩型碳酸盐岩油藏为例,分析该类油藏的储层主要特征及开发过程中面临的主要问题,包括礁滩型优质储层的主控因素及分布规律需进一步研究;礁滩型储层的内部非均质性极强;流体性质分布复杂,其识别与预测难度大等问题。为此,提出相关的开发技术策略,包括巨厚膏盐层地震模型修正技术;建立沉积模型,利用井震联合对礁滩层序进行精细划分与对比;多角度确定储层和流体性质分布规律;精细三维模型刻画礁滩油气藏;多种措施并施,在控制费用的情况下不断提高单井产量等策略,为该类油藏的高效开发提供思路和参考。The development of reef-shoal carbonate reservoir is restricted by many factors,such as sedimentary environment and late reformation,and there are various challenges in the development process.Sapinhoa huge reef-shoal carbonate oil reservoir was studied as an example in this paper and the main characteristics of the reservoir and main problems in the development process are analyzed,in which the main controlling factors and distribution regularity of high-quality reef-shoal reservoirs need to be further studied.The internal heterogeneity of reef-shoal reservoir is very strong,the distribution of fluid properties is complex and its identification and prediction are difficult.Therefore,relevant development technology strategies are proposed.A variety of measures are combined to improve the output of single well under the control of cost,providing ideas and references for the efficient development of such reservoirs.
