塔河油田9区岩溶缝洞型酸性凝析气藏滚动开发实践及认识

Rolling Development Practice and Understanding of Carbonate Karstification and Fractured-vug Acidic Condensate Gas Reservoir in Block 9 of Tahe Oilfield

塔河油田9区奥陶系为超深层岩溶缝洞型酸性凝析气藏,具有一定的特殊性,系统开发难度大。通过实施滚动开发,实现了储量高效动用,短期内建成3亿方天然气生产阵地,取得了较好效果。同时形成了适合塔河地区的碳酸盐岩岩溶缝洞型酸性凝析气藏开发模式,对相同或类似气藏的开发具有重要的指导作用。

The block 9of Tahe oilfield is a carbonate karstification and fractured-vug acidic condensate gas reservoir,which has the more particularity and complexity.It is very difficult to development the reservoir.Through the rolling development,progressing reserves producing steps and maximizing economic benefit,and built a gas reservoir which product 0.3billion square gas a year in the short period of time.At the same time,the development mode of carbonate karstification and fractured-vug acidic condensate gas reservoir for Tahe oilfield was formed,and play an important role in the development of the same or similar gas reservoir.
