Factor Analysis of Vertical Hydraulic Fracture Geometry in Coal Bed

摘要：

　　Hydraulic fracturing is one of the effective means to enhance coal bed methane production for vertical wells.This paper presents an approach that uses pseudo-3D fracture propagation model to study the influence of petrophysical properties, differential stress, treatment conditions, etc.on fracture geometry.It is shown that differential stress, pump rate is proportional to fracture length and width; elastic modulus, Poissons ratio, pump rate, etc.is proportional to fracture height.The finding is of great importance for acquiring ideal fracture geometry.
