摘　　要：为了降低油田特别是中低渗透油气田井网部署和注水(含高压注水)开发的风险,减少储层压裂改造的盲目性,实现油田的合理开发,必须对储层水力缝裂的形态有较准确的预测,而这种预测必须建立在对储层现今地应力了解的基础之上。应用测井资料研究计算现今储层地应力,是一种低成本计算储层地应力场分布的研究方法。实例计算结果表明,这一方法求得的地应力剖面资料和同一储层地应力平面分布资料有一定的准确可靠性,可以用于指导低渗透油田的井网部署和储层的整体压裂酸化改造,有一定的推广应用价值。In order to lower the risk of well pattern arrangement and waterflood development(including high-pressure water injection)in oilfields especially in the oil and gas fields with middle-low permeability,reduce the blind- hess of fracturing reformation and realize the rational oil- field development,an accurate forecasting of the shape of hydraulic fissure based on the current underground stress of reservoirs must be obtained.The method depending on logging data is a low-cost research method to calculate the underground stress of reservoirs.Compared with the plane distribution of underground stress in the same reser- voir,the underground stress profile got from the method is more accurate and can be used as the guidance for well pattern arrangement with low-permeability and fractu- ring reformation of all reservoirs.The example calculation results show this method possesses great application and popularization value.
