Numerical Simulation on Production Forecast of Well by Tip Screen Out Fracturing;

This paper describes the fracture porosity,permeability obliquity,density,and length using the static data and experience formula and analyses the fracture development degree using the dynamic data such as production,well connectivity,etc.

Based on the problem for the starting pressure gradient and strong stress sensitivity for the low permeability reservoirs,the paper has established the production formula for horizontal wells with hydraulic fractures in different circumstances.
