摘要
如何充分利用报废资源降低油气田开发投资和成本 ,运用先进的套管开窗侧钻定向井技术 ,能有效地解决川西地区失去开采价值的近百口生产井进一步挖潜的技术难题。侧钻井开窗方式已由原来的斜向器套管开窗 ,逐步发展到锻铣和地面套管预开窗方式。文中分析在川西地区老井开窗侧钻定向井 ,浅井可节约投资 40 %左右 ,中深井可节约投资 44
Using advanced sidetracking directional well techniques can make full use of abandoned well resources and reduce development cost of oil/gas field.The methods of casing window have changed from original casing window using wipstock to section milling and test of casing window on the surface.The paper analyses re-entry sidetracking directional well technology in west Sichuan,it can reduce cost about 40% in shallow well and about 44% in middle-deep well
