水力压裂法地应力测量中的几个问题

Discussion on application of hydraulic fracturing method to geostress measurement

回顾了应用水力压裂法测量地应力的基本原理。简要地分析了对水力压裂法地应力测量结果的可靠性影响较大的几个参数。最后,对水力压裂法在深部地应力测量中的应用及其在深钻孔地应力测量方面的发展前景也做了讨论,指出了今后深部地应力测量研究努力的方向。

The fundamental principle of hydrofracturing method for measuring geostress is reviewed. Several parameters which have important effects on the reliability of results obtained from This method, are briefly investigated. And its prospects of hydraulic fracturing method to estimate the state of geostress in deep-hole stress determination are discussed. The trend of geostress measurement at great depth is pointed out.
