苏3X-1区块侧钻水平井优选方法研究

Research on Optimization of Sidetracking Horizontal Well in the Su3X-1 Block

近年来技术日趋成熟的老井侧钻水平井技术,具有提高气藏开发水平、节约钻井成本等方面的优势,已经在苏里格气田得到了试点应用并取得了良好效果。在研究借鉴前人成果基础上,通过对已侧钻水平井产量、地质条件、井况条件及开发预测指标进行详细分析,结合净现值计算公式,进一步建立完善了侧钻水平井的产量、储量及经济评价标准,并根据标准优选了苏3X-1区块并设计了苏3X-X-XCH侧钻水平井。

In recent years, thanks to increasing maturity and enhancing the level of gas reservoir development and saving drilling cost etc. old well sidetracking horizontal well technology has been applied in a pilot and achieved good effect in the Sulige gas field. On the basis of detailed analysis of sidetracking horizontal well production, geological conditions and development indices in combination with the calculation formula of net present value this study establishes and improves the sidetracking horizontal well production, reserves and economic evaluation standard. According to the standard, the Su3X-1 block is optimized and the Su36-x-xch side drilling horizontal well is designed.
