突尼斯深海Oudna油田大排量气举工艺设计

为了快速高效的开发海上油气田,研究人工举升方案显得尤为重要。本文描述了Oudna油藏的地质特征、油藏条件及其流体物性。通过对Oudna油田的认识,从气源角度分析了采用燃烧废气作为气举气源的可行性并提出了气举开发的工艺流程。

Gas Lift Technological Design for the High Volume Ratesin Oudna Oilfield Offshore Tunisia

It is very important to study the artificial lift scheme so that the maritime field can be developed quickly and with high efficiency.The maritime development for environmental condition usually requires that the volume of the equipment on the platform or production vessel is enough small,weight light,free repair long,adaptability good,etc.Gas lift is a kind of the mechanical production technology with good adaptability,has been used widely onshore or offshore.The paper depicts oudna reservoir geologic feature,reservoir conditions and fluid property.With the knowledge to Oudna field,Use of power generation exhaust as liftgas source is analyzed from the liftgas resource view,and gaslift surface procedure.By analyzing gas lift performance curve,the conclusion that gas lift can meet the requirement of big volume 3180m3/d(20000B/D)can draw.The main factors including in gas injection depth,gas lift mode,tubing&casing program,formation pressure and water cut are analyzed in detail with gas lift system analysis method,in the end,the ideas plan is suggested,compares with Lundin Petroleum AB's jet pump design,a great deal of money for completion well is saved.
