摘要
安塞油田坪北区属于典型的特低渗透、微裂缝发育的低压、低产油藏,地面、地下条件复杂,1997年以前一直未投入开发。1998年5月采用了先进的井网优化部署和适合采油及地面建设的工艺技术,成功地开发了这种特低渗透油藏,取得了良好经济效益。本文总结了坪北区油藏四年来产能建设和注水开发的主要作法、先进的井网优化部署和早期注水对类似油藏的开发有指导作用。
Pingbei Area of Ansai Oilfield is a typical low pressure and low production reservoir with extra-low permeability and micro-fractures development. With complex topography and subsurface conditions, it was not put into production until 1997.In May 1998,we utilized advanced well pattern optimization arrangement and suitable oil production and surface construction techniques,developed this extra-low permeability reservoir successfully,and achieved great economic benefit.This paper has summarized four years'main experiences of productivity construction and waterflooding , advanced well pattern optimization arrangement, and early stage waterflooding in Pingbei Area. These experiences are very significance to guide the development of similar oil reservoirs.
