摘　　要：分析了近几年交叉偶极阵列声波资料在川中地区所钻井的实际应用情况,利用交叉偶极声波测井资料计算出××2井长兴组的地层应力(地层闭合压力和地层破裂压力)和压裂缝高度,其结果可为试油设计与储层改造等提供有力的依据,在川中地区具有较好的应用效果。Cross-dipole acoustic logging is a better method for measuring formation compressional wave, shear wave and stonely wave. Analyzed are applications of cross-dipole acoustic logging data in central Sichuan area in recent years. Based on cross-dipole acoustic logging data, calculated are formation stress（ formation closure pressure and fracture pressure） and fracture height. Provided is the base for oil test design and reservoir reconstruction. Applications show that the method is better.
