摘　　要：克拉美丽气田是准噶尔盆地的重点天然气勘探区带和新疆油田的重点产能建设区块。地应力场的研究将为该气田开发方案制定、开发井网部署、储层改造、井壁稳定性分析等地质与工程难题的解决提供指导和依据。选取关键井测井资料,利用钻井诱导缝推断法和井径测量法确定了地应力方向;运用美国斯坦福大学的地应力模型和图版解释法计算出地应力大小,具有较高的精度和较好的连续性,计算值与实测值符合程度高。Kelameili Gasfield is a key natural gas exploration play in Junggar Basin and also an important productivity construction block of Xinjiang Oilfield.Study on ground stress field will provide guidance and reference for solving the geological and engineering difficulties such as the development planning,the development well pattern arrangement,the reservoir reconstruction and the borehole stability analysis in the area.The logging data of key wells were selected,and the ground stress orientation was determined by drilling-induced fractures inference and caliper logging methods.Ground stress was computed by the ground stress model developed by Stanford University(US)and the chart interpretation method.The computed value,with higher precision and better continuity,accords with the measured value very well.
