摘　　要：在岩心、测井和开发动态等资料的基础上,对馆陶组沉积相、储层特征及隔夹层分布情况进行综合研究,认为馆陶油藏具备单井日产油达到百吨的地质条件;同时利用数值模拟和油藏工程计算手段,从静态指标、动态指标综合分析影响百吨井的主控因素主要有隔夹层、储层非均质性和操作压力不均衡等,并确定实现百吨井的技术界限,制定驱泄复合技术、水平段均衡动用技术、操作压力控制技术和Sub-cool值调控技术等对策,实现了单井日产油达到百吨的目标,为类似区块实现SAGD单井高产提供了借鉴。Based on the data of core,logging and dynamic data,this paper comprehensively studies the sedimentary facies,reservoir characteristics and distribution of the interlayer in the Ng Formation,and holds that the Ng reservoir has the geological condition of 100 tons of single oil per day. At the same time,using the numerical simulation and reservoir engineering calculation method,the main controlling factors affecting the 100-ton-wells from the static index and the dynamic index are mainly interlayer,reservoir heterogeneity and unbalanced operating pressure. It is determined to achieve technical limits of 100-ton-wells,making flooding composite technology,the even use technology of horizontal section,operating pressure control technology and sub-cool value control technology and other countermeasures to achieve the goal. It provides a reference for similar blocks to achieve SAGD single well high yield.
