摘要
以辽河盆地冷４３断块需要压裂投产的深层巨厚稠油油藏为例，运用井壁崩落、水力压裂、岩心分析等方法确定该油田最大水平主应力方位和大小，为该类油藏压裂裂缝延伸方向的预测和油田开发井网的合理部署奠定了基础，也为类似油藏的高效合理开发提供了理论依据。
Taking the deep high thickness viscous oil reservior where fracturing must be conducted at Leng 43 Block of Liaohe Oilfield as a example,the orientation and magnitude of maximum horizental principle stress are determined by use of sidewall failure,hydrulic fracture and core analysis methods,etc.Thus,the base is formed for fracturing fracture extendly orientation prediction and proper well pattern modification of oilfield development, also provided theoritical basis for high efficient and reasonable development of such reserviors.
