塔里木盆地北部油田古应力的AE法测量

PALEOSTRESS IN NORTHERN TARIM OIL FIELD ESTIMATED BY AE

本文在阐述了声发射（简称ＡＥ—ＡｃｏｕｓｔｉｃＥｍｉｓｓｉｏｎ）法测量古构造应力的可行性之后，着重介绍了测量古应力与测量现今应力在方法上的不同之处。作者采用ＡＥ法测量了塔里木盆地北部油田古应力，并得出该区喜马拉雅期有２幕主要构造运动；燕山期有３幕主要构造运动；古生代有２—３幕主要构造运动的认识。喜马拉雅构造运动在该区占主导地位。

After a feasibility study of the application of AE method to the measurement of paleostress emphasis is placed on the discussion of the methods used in paleostress measurements and current stress measurements by AE in the paper.Paleostress measurements by AE in Northern Tarim Oil Field show two-episodes of tectonic movements in the Himalayan movement three in the Yanshannian movement,and that the Himalayan was the most dominant.
