摘要
吐哈油田地质情况比较复杂,其特点是:低孔、低渗裂缝发育。针对其特点,本文从油藏研究入手,立足现场需要,研究了有针对性的裂缝油藏化学调剖技术,对化学调剖的适应性、调剖机理、化学剂配方、选井、选层工艺技术、调剖工艺技术、配液工艺技术、质量控制技术均进行了研究、配套和应用,形成了适合裂缝油藏的化学调剖技术系列,取得了明显的实施效果,为油田的稳油控水发挥了重要作用。对吐哈油田化学调剖技术的发展具有重要的技术指导作用。
The complex geology of Tuha oilfield has the characteristics of low porosity,low permeability and abundant fracture.In accordance with these characteristics,technology for fractured reservoir was investigated starting from the study of the reservoir.The suitability of profile control agents,the mechanism of profile control,the formula of chemical agents,well selection,interval selection process,profile control technology,fluid distribution process and quality control technique have all been studied,matched and applied.A series of chemical profile control technolo- gy suitable for fractured reservoir which has made great contribution to the water control and production stability, of Tuha oilfield has been established.This is an important reference for the development of chemical profile control technology in Tuba oilfield.
