| 摘 要： | 作者采用声发射法测量了塔北油田、中原油田的古今应力值，并用实测数据反演模拟了中原油田的构造应力场，出油井现今最大主应力值低于非出油井的特点可直接用于评价含油构造与非含油构造，而且，测量现今应力的大小为油田开发注水压裂的泵压参数的选取和开有层采的划分提供了重要的依据。

| Abstract: | Fossil and present-day rock stresses in the Tabei, Zhongyuan, and the Keerkang Oil Fields have been measured using acoustic emission (AE) technique. It has been found by an analysis of the relationship between known oil/gas distribution and stress state that thepresent sreatest principal stress in the Tabei Oil Field is below the average of the country, and that the stress in producing wells is lower than that in the non-producing wells. Therefore, the magnitude of the current stress may serve as a criterion for distinguishing oilbearing structures, for choosing the parameters of pumping pressure, and for the division of production horizons. |
