摘要
Tectonic compaction has great influence on the properties and distribution of reservoirs in the Kuqa foreland basin. On the basis of logging responses to tectonic compaction, quantitative models were set up to determine the distribution of palaeotectonic stress by logging data and to analyze the influences of tectonic compaction on reservoirs. The influences showed dual nature: With intense tectonic stress, both porosity and permeability become poor, in particular, permeability is more sensitive to tectonic stress. This provides a favorable foundation for reservoirs to keep higher porosity and permeability.
