摘要
塔河油田奥陶系油藏为典型的缝洞型碳酸盐岩油藏。随着注水效果逐渐变差，有必要探寻碳酸盐岩缝洞型油藏开采的新方法，其中注气开采是有效手段之一。以提高碳酸盐岩缝洞型油藏注气效率方法为研究目的，通过对比溢出口距离、注气时机、注气速度和注气作业的气水比，提出了提高碳酸盐岩强能量油藏注气效率的方法。
Abstract
The Ordovician reservoirs in the Tahe oil field are typical fractured-vuggy carbonate reservoirs. As water injection efficiency becomes worse gradually, new methods for fractured-vuggy carbonate reservoirs are demanded, among which gas injection is an effective way. Spillway distance, gas injection timing, gas injection speed, and gas/water proportion were compared, putting forward a new method for improving the gas injection efficiency of carbonate reservoirs.
