Characteristics and Controlling Factors of Natural Fractures in Continental Tight-Oil Shale Reservoir
نویسندگان
چکیده
Natural fracture growth plays an important role in shale-oil enrichment. Systematically investigating features and their controlling factors reservoirs is essential for accurately predicting distribution. The of distribution the continental shale Qingshankou Formation Songliao Basin, China, were systematically analyzed based on quantitative characterization outcrops cores. Strata-confined fractures, throughgoing bedding-parallel stylolites can be observed reservoir study area. Fracture not only controlled by internal factors, e.g., mineral composition, mechanical stratigraphy, lithofacies, but also external faults abnormally high pressure readings. Mineral composition primary factor governing development, it controls abundance, affects filling effectiveness. Mechanical stratigraphy determines spatial morphology developmental pattern a fracture. Fractures are well-developed brittle strata, with spacing being proportional to bed thickness. Lithofacies determine development variation rock structure, thickness, etc. Stress concentration commonly at fault tips, intersections, overlaps, where density has good connectivity. existence reduces effective stress, promoting shear development. Tensile overpressure fractures generated under small levels differential stress.

متن کاملThe Role of Natural Fractures in Shale Gas Production
Natural fractures seem to be ubiquitous in shale gas plays. It is often said that their presence is one of the most critical factors in defining an economic or prospective shale gas play. Many investigators have presumed that open natural fractures are critical to gas production from deeper plays such as the Barnett, as they are for shallower gas shales such as the Dev‐ onian shales of the nort...

Reservoir Characterization and Quality Controlling Factors of the Fahliyan Formation Located in Southwest Iran
The Berriasian-Valanginian Fahliyan Formation forms one of the giant reservoirs in the subsurface of the Abadan plain, onshore Iran. A detailed petrographical analysis of the available cores and thin sections revealed that the different diagenetic parameters influenced the reservoir quality of the Fahliyan Formation in this field. The Fahliyan Formation has been influenced by three diagenetic e...
