Study on well logging with crustal stress calculation in Yuanba gas field
摘要
Abstract
Using the logging data to study crustal stress has important significance for drilling,reservoir transformation and development in Yuanba gas field.In this paper,the formation of rock mechanics parameters (compressive strength,tensile strength,Poisson ratio,elastic modulus,cohesion,internal friction angle)were calculated by logging data.Using fracturing data invert tectonic strain coefficient.The pore pressure and pore elastic coefficient were determined by previous studies.Ap-plication of combined spring theory,build crustal stress calculation model of Yuanba gas field.The accuracy of this method is testified through rock acoustic emission earth stress experiment.From the depth of stratum,lithology analysis of the stress profile characteristics of this area,design guide post casing selection,drilling construction proj ect etc.关键词
