摘要：Strong tectonic compression has an important influence on the generation and evolution of formation overpressure,and the identification and estimation of tectonic compression overpressure need to be further studied.Based on the correlation between rock mechanics characteristics and reservoir physical property parameters,This paper systematically analyzes the differences of vertically effective stress,acoustic velocity and density logging response between tectonic compression overpressure formation and hydrostatic pressure formation under the same stress condition,and establishes the identification template of tectonic compression overpressure.According to the pore elasticity theory,the traditional equivalent depth method has been improved,and the calculation method of tectonic compression overpressure (mean stress method) is also proposed.Based on actual drilling pressure,regional geological data and comprehensive compaction characteristics of mudstone,the paper identifies the tectonic compression overpressure with different strengths in the Kelasu-Yiqikelike tectonic belt of Kuqa depression.Based on the calculation of three-dimensional principal stress.Then a quantitative evaluation is performed on the pressurization caused by tectonic compression.Tectonic compression plays an important role in the genetic mechanism of formation overpressure in Kelasu-Yiqikelike tectonic belt,and its contribution rate for formation overpressure is obviously positively correlated with tectonic strength.The contribution rate of tectonic compression in Well KS6 area of Kelasu tectonic belt ranges from 43.2% to 44.4%,and that in Well DB6 area is from 34.1% to 39.3%.The contribution rate of tectonic compression in Well YS4 area of Yiqikelike tectonic belt ranges between 32.8% and 34.7%,and that in Well TX1 area is between 21.1% and 22.0%.The research methods and understanding will provide research ideas for the formation pressure prediction of tectonic compression basins and a theoretical guidance for seeking favorable reservoirs. ? 2022 Science Press.
