选择合理井网类型及井网密度是油田开发设计的核心内容,其大小直接影响采收率的高低和经济效益的好坏。本文以沈161块低渗砂岩油藏为对象,在综合地质研究的基础上,分析开发中存在的主要矛盾及潜力,对井网密度进行综合评价,确定适合本区的技术上可行、经济上最优的井网密度,在区块边部有利地区部署井位,实现低渗透砂岩油藏有效开发。 Choosing the right type of well pattern and the density of well pattern is the core content of oilfield development and design, and its size directly affects the level of recovery and the economic benefits. Based on the study of comprehensive geology, this paper analyzes the main contradictions and potentials in the development of Shen 161 low permeability sandstone reservoir and makes a comprehensive evaluation of the well pattern density to determine the technically feasible and economically appropriate for this area Optimal well density, and deployment of wells in the favorable area of ​​the block, so as to effectively develop low-permeability sandstone reservoirs.
