In continuous formations, the rock properties and the state of in situ stresses control the
propagation direction of an induced hydraulic fracture (HF) and its geometry. The present …

Glutenite is an important unconventional tight oil and gas reservoir. Due to the glutenite
formation with strong heterogeneity and variable lithology which contains a large number of …

Shale oil, primarily existing in organic-rich shales from lacustrine basin, would amount to a
huge resource in China. Currently, this kind of resource is pervasively distributed in basins …

Unconventional reservoirs such as shale and coal rock are generally well-bedded, with
significant differences in the interlayer stress and rock physical parameters. The change law …

埋深大于3 500 m 的深层页岩储层具有高水平主应力差, 发育层理裂缝, 低脆性指数等特点,
在压裂改造时难以形成复杂裂缝. 为了充分认识其水力裂缝扩展规律, 采用三维离散格子方法对 …

Multiple cluster hydraulic fracturing is widely used in the development of shale reservoir. The
morphology of multiple fractures propagating from multiple cluster is complex due to the …

Multistage fracturing with multiwell pads (MSFMP) is an essential technology for the efficient
development of unconventional oil and gas reservoirs, but the reservoir area between two …

In recent years, multi-stage hydraulic fracturing for shale oil reservoirs is developing toward
a shorter cluster spacing and a larger number of clusters per stage. The objective is to …

The competitive initiation from multiple perforation tunnels and the non-planar propagation
near the wellbore for different perforation technologies are not fully understood. Laboratory …

Multi-cluster fracturing in horizontal wells is a key technology for successful development of
ultra-low permeability reservoir. The propagation of hydraulic fracture during multi-cluster …
