瓜尔豆胶硼酸盐的压裂液的合成方法的流变学研究
|
Hydraulic fracturing is a method to extract natural gas from shale rock formations. The fracturing fluid, almost completely water based, is comprised of hydroxypropyl guar (HPG), cross linking agent(s), mineral salts, pH adjusting agents, and other components to regulate rheological behavior. To access the natural gas, the fracturing fluid is pumped at high pressures down into a well to fracture the shale formation. Once the fractures are created, they are held open by proppants, typically crystalline silica, which fills in the cracks created to allow for the appropriate flow of hydrocarbons. Once the proppant is in place, a breaker entity is added to decrease the viscosity of the gel and allow the fluid and the natural gas to flow back up the well for recovery. This method of natural gas extraction is an efficient means of providing natural resources; however, the current fluid components used in industry are hazardous and present health risks upon unanticipated exposure. The ultimate goal of this research is to develop a model of current fracturing fluid behaviors. From these models, a solidified method for fracturing fluid synthesis can be explored using environmentally friendly chemicals. |
