| 摘 要： | 地应力的研究对能源发展、水利及交通设等都起着重要作用.水利压裂法是测量最小水平地应力的一种简便可靠方法,但直接获取最大水平地应力较为困难.本文采用最小二乘法对多组水力压裂数据联立求解,同时获得了最大和最小水平地应力.对中国南海某盆地的压裂数据进行实例计算,其结果符合当地地质构造.

| Abstract: | It has very important function to study the in-situ stress to energy development, water conservancy project, transportation construction and so on. Hydraulic fracturing method is a simple and feasible method to get minimum horizontal in-situ stress. Thus, it is also difficult to get maximum horizontal in-situ stress. We can acquire the maximum and minimum horizontal in-situ stress at the same time from the hydraulic fracturing data by using least square method. The results calculated from fracturing data of a basin in South China Sea are consistent with the local geological structure character. |
