| The current widely used three fracturing fluid system has its own shortcomings, and fracturing fluid at home and abroad still has many problems not solve in the process of development, therefore, developed a series of thickening ability, low water content, high temperature stability and good shear stability and lower the cost of the fracturing fluid has been the development direction of fracturing fluid research. This topic will study three new guanidine gum fracturing fluid system, and named it "new electric attraction from associating fracturing fluid" system, the fracturing fluid system adopts the new anchoring mechanism,cost is far lower than the guanidine gum and other fracturing fluid system, and to 180 ℃ of heat-resistant, with a low solid, no residue, low friction, shear resistance is good wait for a characteristic, form a new fracturing fluid system.This topic from theoretical research, at present the main theory of fracturing fluid viscosifier viscous carried on the thorough analysis and research, so as to design electric attraction can be screened out from the association of thickening agent and surfactant,synthetic products, studies the influence of synthesis conditions on the performance, select the suitable fracturing fluid formulation system, and to evaluate the performance of fracturing fluid system.Water-based fracturing fluid system, the author of this paper thickener in recent years,the price is higher, and high residue of reservoir damage, caused by fracturing construction cost is high, the fracturing effect is poor, by the three sets of guanidine gum fracturing fluid system, the main agent of synthesis and the synthesis optimization of process conditions and the series of guanidine gum fracturing fluid compared with conventional fracturing fluid system to conduct a comprehensive evaluation, no guanidine gum fracturing fluid system have completed three sets of the best recipe research, HAS formed series thickener and technological achievements. |
