周青庄油田水平井开发的实践与认识
|
摘要
周青庄油田沙三段发育致密砂岩储集层,具有"埋藏深、储量丰度低、低孔特低渗"特征,常规井开发效果不理想。为提高该类油藏采收率,在整体油藏地质特征研究及开发特征分析的基础上,开展了水平井适应性分析及水平井产能分析,运用"水平井采油,常规井注水"的开发方式,对水平井在该区的实施效果进行分析和总结。结果表明低渗透油藏应用水平井技术可以有效改善开发效果。
Tight sandstone reservoirs are developed in the third member of Shahejie formation in Zhouqingzhuang oilfield,characterized by deep burial,low reserve abundance and low porosity and ultra-low permeability.Conventional well development effect is not ideal;the horizontal well adaptability and productivity analysis are carried out based on the research of geological and development characteristics of integral reservoir to improve the recovery rate of this type of oil reservoir.Horizontal well production and conventional well water injection are recommended.The implementation effects of horizontal wells in this area are analyzed and summarized.The results show that the application of horizontal well technology in low permeability reservoirs effectively improves the development of oil field.
