摘要
本文针对元坝陆相地层开展了岩石力学参数测井分析评价研究。以岩石力学实验室测定结果为基础,结合密度、声波时差等测井数据,经数理分析后建立了岩石力学参数测井计算模型,并应用到岩石可钻性、破裂压力、坍塌压力等工程地质参数的计算,研究成果在现场钻井中获得较好的应用效果,表明构建的岩石力学参数计算模型对具有较好的适应性,能够给钻头选型、安全钻井液密度窗口等工程参数设计提供可靠的依据。
In view of terrestrial formation in Yuanba area,research of logging evaluation method of rock mechanics parameter is carried out.Based on the laboratory rock mechanics test results, combined with the density, sonic logging data, the mathematical analysis model is established for calculating the rock mechanics parameters. It is applied to calculation of the rock drillability, fracture pressure, collapse pressure and other engineering geological parameters. The results obtained good application effect in drilling engineering. It shows that the model has good adaptability and can provide a reliable basis for engineering parameter design such as drill bit selection,safe drilling fluid density window,etc.
