摘要
高效开发非均质性较强的低渗气藏,关键是选用最佳布井方式和优选合理的开发井网。本文以长庆靖边下古气藏陕66井区为例,在综台分析靖边下古气藏陕66井区单井经济极限初始产量、单井控制经济极限地质储量、经济极限井距、合理井网密度和采气速度等各个影响井区合理布井的因素的基础上,形成构造轴部井密、翼部井稀的非均匀面积井网的布井方式,并结合经济评价研究,得出了高低丰度区不同的合理井网密度,可为合理高效开发气田提供科学依据。
Under the condition of current market economy,gas reservoir development was focused on the economic benefit.The key point to develop efficiently anisotropic low permeability gas reservoir was to select the optimal and reasonable well pattern.The paper took Block Shan 66 in lower Paleozoic gas reservoir in Jingbian for example,based on analyzing comprehensively each factor such as single-well economic limit initial production,single-well controlled economic limit OOIP,economic limit well spacing,reasonable well spacing density and gas recovery rate to affect reasonable well pattern of Block Shan 66,non-uniform area well pattern that was denser in structural axis while sparser in structural alar was concluded.By combining with economic evaluation,reasonable well pattern density,well spacing and gas recovery rate in high and low abundance areas were concluded,which can provide scientific basis for reasonable and efficient development of gas reservoir.
