Frac sand fracturing process for a particular

Fracturing is a special process method differs from conventional fracturing frac sand fracturing, it can change the normal size ratio cracks to some extent, to achieve filling "short wide crack" special purpose, in order to meet certain the high permeability reservoir fracturing of ceramic proppant manufacturers special needs. "De-fracturing technology" is divided into seven chapters. Chapter 1, a brief overview of the main research areas of special research requirements fracturing technology system and the removal of frac sand fracturing. Chapter 2 briefly describes the removal of frac sand fracturing technology generation and development process and formation ultra lightweight proppant fluid flow patterns from fracturing study analyzes the necessity of the implementation of high-permeability formations off the frac sand fracturing. Chapter 3 discusses the cracks in the surrounding frac sand off the frac sand off the microscopic mechanism and technical conditions. Chapter 4 discusses the control mechanism of the cracks around the belt off of crack propagation. Chapter 5 discusses the three-dimensional crack propagation law resin coated silica sand and crack off the frac sand in front of the one-dimensional variation off the frac sand after. Chapter 6 summarizes the removal of sand fracturing design methods, including time off the sand off the sands of time to design and limited, and the amount of fluid distribution design methods.
