摘要
Abstract
Because the cretaceous tight sandstone reservoir in the front of high steep tectonic of Kuche forelandbasin is abnormally high pressure and strong stress,it is difficult for the conventional well logging interpretation technique to evaluate the effectiveness of the reservoir accurately.The evaluation result is often inconsistent with the oil/gas test,which affects the effectiveness of the exploitationin.Hence,it is necessary to understand the correlation of the crustal stress value and direction with the reservoir validity and how to evaluate reservoir validity.From the perspective of rock mechanics,firstly calculated the crustal stress of high deep tectonic formation,and then studied the corresponding relation of situ stress and reservoir validity,and extracted such parameters as effective crustal stress ratio and direction stress difference,and established evaluation criteria of reservoir validity and distinguished high-quality reservoir,and finally formed a set of key methods and techniques toevaluate the reservoir validity of high steep tectonic.T his set of method and techniqueprovides a full new approachtoevaluate the deep fractured sandstone reservoir validity from well logging information.Anditalso provides reliable rock mechanics basis for selecting layer in oil testing,acidification and fracture.Good results has been achieved to apply this method to reservoir validity evaluation of new wells.It is worthy of popularization and application.关键词
