Abstract

Abstract:

The organic matter and clay minerals in shale can combine with each other to form organic-clay composites during sedimentation and evolution， which are an important source of parent materials of hydrocarbons. An integration of field emission scanning electron microscopy （FE-SEM） and transmission electron microscopy （TEM） is applied to study the deformation and micro-architecture of organic-clay composites， and discuss their source-reservoir significance in depth. The object of study is the four suites of typical shale reservoirs， that is， the Triassic Yanchang Formation of the Ordos Basin， the Ordovician Wufeng-Silurian Longmaxi formations of northern Guizhou， the Cambrian Niutitang Formation of central Guizhou， as well as the Permian Shanxi Formation of the Southern North China Basin. The organic-clay composites in shale feature complex components， diverse geometries and being prone to deform， and the main mechanisms driving the deformation mainly include tectonic stress， mineral particles， the occurrence of organic matter and the transformation of clay minerals. The deformation caused by tectonic stress outside the composites and mineral particles （imposed on the surrounding clay layer and organic layer） inside the composites could change the local stress environment of the composites， resulting in extensional environment， which could in turn drive the large-scale development of nano-pores in the composites. Under the protection of clay layer， hydrocarbons stored in the nano-pores are less likely to loss， which could effectively improve the storage capacity of shale reservoir. The conclusions achieved in the study are of beneficial value to understanding the diagenetic evolution of shale， as well as the generation， migration and storage of shale oil and gas， thus guiding the exploration and development of shale oil and gas.

Key words: micro-architecture, deformation, extensional environment, storage capacity, organic-clay composite, shale
