摘要
在井网一定的条件下,油田开发效果取决于古水流,研究古水流分布规律、进行储层描述。在沉积微相内划分古水流,在古水流内完善注采关系。使用古水流对生产井进行分类研究;提出渗流地质模型、主流线、次流线、滞流线、横流线;在古水流与油藏动态分析、综合措施挖潜应用领域进行了探索和研究。提出改善开发效果措施。
Oilfield development response depends on palaeocurrent under certain well pattern.This paper studies palaeocurrent distribution for reservoir description.Palaeocurrent is divided within sedimentary microfacies,and injection-production relationship is improved in palaeocurrent system.Production wells are divided by using palaeocurrent.A geological model of flow through porous media,channel line,sub-channel line,alluvial line and cross-current line is presented.Palaeocurrent,reservoir performance and comprehensive stimulation are analyzed and studied for enhancing development response.
