摘要
地层压力的预测对于保护油层、合理设计井身结构和钻井液密度具有重要意义。以国外K油田18 a的地层压力测试数据为基础,借鉴分形理论中R/S分析法的基本原理,提出了运用Hurst指数预测地层压力变化的新方法,研究并预测了K油田地层压力的变化趋势。为油田开发中后期安全、高效地开发提供了依据。
Formation pressure forecast is critical to reservoir protection and reasonable design of hole structure and drilling fluid density.Based on 18 years' formation pressure test data of the K Oilfield,this paper introduces Hurst index as a new method to predict formation pressure change with the help of the basic principle of R/S analysis in fractal theory.The trend of formation pressure change in the K Oilfield is studied and predicted.This study has provided a basis for reliable and efficient development in the middle and later oilfield life.
