摘要: 在新疆迪那气田,根据对地应力分布规律和影响它的诸多因素的分析,引用前人的研究成果,充分利用测井信息,计算了岩石的力学参数、岩石固有强度参数,确定了地应力计算模式中的各参数。测井分析地应力不仅可以方便、迅速得到沿深度连续分布的地应力剖面,而且节约了昂贵的地应力测试费用,具有明显的经济意义和实用价值。同时,利用井壁崩落法、钻井诱导缝法和DSI 快横波方位法确定了新疆迪那气田目的层的水平主应力方向。

Abstract: The earth stress distribution and influenced factors in Dina gas field in Xinjiang are analyzed. The parameters required for earth stress calculation are determined, such as the rock mechanics and the inherent rock strength using well log data and available results. Using well log data to analyze earth stress is not only to quickly get the stress profile spreading along the depth, but also to save high cost for measurement. Furthermore, the horizontal stress direction of the target zone in the gas field is determined by means of borehole breakout data, drilling-induced fracture and DSI Fast shear azimuth.

Key words: well logging, rock mechanics, elastic modulus, poise ratio, earth stress
