摘要： 通过多种测井资料,尤其是利用了偶极横波测井资料研究了轮古东地区碳酸盐岩储集层地应力,分析了该区块现今地应力的方向、分布规律及相对大小。多口井处理结果表明,利用测井资料求取碳酸盐岩储集层地应力方向是一种行之有效的方法。轮古东地区的现今地应力大小与裂缝的发育有明显关系,并且在一定程度上控制着局部油气聚集。

Abstract: The eastern Lungu area in Tarim basin is of the stress with significant effect on the fractural development in its carbonate reservoir, with obvious differences of fractural development in different local stress fields. This stress is studied by using various well log data, particularly using dipole shear -wave acoustic log, including the present orientation, distribution and relative size of the stress. The multi-well processing results show that the stress direction/ orientation in carbonate reservoir obtained from well log data is an effective method. It is indicated that the present stress size in eastern Lungu area is closely related to its fractural development, thus controlling the local hydrocarbon accumulation to a certain extent.

Key words: Tarim basin, in-situ stress, fracture, dipole, shear wave, well log, carbonate reservoir
