复杂断块油藏高含水期注水开发特点和技术对策
|
摘要
本文从油藏研究的深入、中高渗油藏水驱特点、井况影响以及注水开发系统性特点等方面系统分析了精细注水开发面临的特点和挑战。提出了提升两个技术理念技术对策。将提升完善注采关系本质解释为:(1)平面上完善单砂体注采井网。(2)纵向上通过分层细分层和细分注来改善水驱。(3)在渗流能力相近的砂体构型单元内组建注采关系。(4)采用PV级的深部调驱来降低无效低效水循环。(5)充分运用注采调配优化渗流驱替效果,为同类油藏下步精细注水开发和提高水驱采收率提供了可借鉴的经验。
This paper has analysed the characteristics of fine water injection development is faced with and challenge, considering the deep of reservoir research, high permeability reservoir water flooding characteristics and well conditions affect and waterflood systemic characteristics, etc.The author has put forward two technology concepts, which would improve essential explanation for perfecting injection-production relationship,(1)Improvingsingle sand body perfect injection-production well spacing on the plane.(2)Improving the water flooding through the layered stratification and subdivided injection vertically.(3)Building up injection-production relationship in the seepage ability of similar sand body configuration unit.(4)Reducing invalid inefficient water cycle level by PV displacement.(5)Making full of the allocation of injection-production to optimize flow displacement effect.This paper pro-vides reference experience for the similar reservoir fine next waterflood development and improve water drive recovery factor.
