Optimization method and application of sanding concentration in fracturing design
Drilling & Production Technology(2007)
Abstract
Based on the dimensionless flow conductivity(Fcd=1.3~1.6),comprehensive damage coefficient(95%-98%)of fracture,and combining optimized fracture length and linearity sloping sanding programming,the optimization method of sanding concentration in fracturing design was formed.The method was carried out the pilot tests in two wells in west Sichuan area,gas open-flow capacity obtained in Mapeng well A is 13.9657×104 m3/d and that in Mapeng well B is 12.6149×104 m3/d.The method provided a new measure for the determination of sanding concentration in fracturing design.
