X区块长4+5油藏开发效果分析与评价

Analysis and Evaluation of Development Effect of Long 4+5 Reservoir in Block X

X区块是位于鄂尔多斯盆地陕北斜坡的低渗透油藏,勘探开发始于2004年。目前该区长4+5油藏采出程度低,开发效果一般。通过对X区块长4+5油藏开发效果分析与评价,总结了低渗透区块长4+5油藏提高开发效果的经验,为同类型油藏提高开发效果提供借鉴。

Block X is a low-permeability reservoir located in the northern Shaanxi slope of the Ordos Basin.Exploration and development began in 2004.At present,the Chang 4+5 reservoir in this area has a low degree of recovery and a moderate development effect.Through the analysis and evaluation of the development effect of the long 4+5 reservoir in Block X,the experience of improving the development effect of the long 4+5 reservoir in the low-permeability block is summarized,and it provides a reference for improving the development effect of the same type of reservoir.
