Transformation of sandbody geometry as the result of enclosing clay rock compaction

Abstract

All rights reserved.During paleogeographic studies the identification of channel, deltaic and avandeltaic environments of sedimentation is obstructed. Experience shows that their definition according to the granulometric composition of constituent deposits is not a sufficient basis for the reference to the category of continental facies. To do this, we should attract some indirect evidence, for example, the drawing of paleo drain network, the geometry of sandbodies and the configuration of basal and lateral contacts, etc. The performed studies demonstrated the transformation of sandbodies due to the nonuniform compressibility of clay and sand rocks, causing to the formation of various pseudo-structural elements in the form of bends and folds. Therefore, during the identification of formation conditions for clastic natural reservoirs the adjustment of trap forms is needed for the processes of enclosing clay rock compaction.
