摘要

针对塔里木盆地塔中缝洞型碳酸盐岩凝析气田试采过程中暴露出的能量不足、递减大的问题,2010年以来,对衰竭开发末期的挥发油藏及凝析气藏,先后选取15个单井缝洞单元开展注水替油,对确认的2个多井缝洞单元开展对应注水,均见到了一定的效果。截至2015年5月,在累计注水29.05×104m3后新增油3.1 ×104t、气848.26×104m3。同时,对注水开发机理进行了研究,对单井注水替油的影响因素、技术政策进行了分析总结,为塔中碳酸盐岩挥发油藏及凝析气藏衰竭期末补充地层能量提高采收率提供了矿场支持。

Abstract

Single well water injection-production technique has been conducted in 15 wells and two injection-production well groups have been established since 2010,aiming at energy deficiency and rapid decline during the production of fractured-cavernous carbonate condensate gas reservoirs in Tazhong,which have achieved a certain effect.Until May,2015,3.1×104t oils and 848.26×104m3gases have been produced by water injection with volume of 29.05×104m3.Meanwhile,water injection mechanism has been researched,influence factors and technique policy of single well water injection-production are analyzed and summarized,which provides a field support for recharging formation energy to enhance oil recovery of carbonate condensate gas and volatile oil reservoirs after depleted stage in Tazhong.
