Use As Oil Drilling Mud Chemicals |
The Application of Oil Drilling Field During oil exploit Polyacrylamide can be used as multipurpose additives.For example:drilling fluid,fracturing fluid and displacement of reservoir oil to enhance oil recovery.
1.Used as drilling fluid additives The function of polyacrylamide are adjust the rheological property of drilling fluid,cutting carrying,and protect drills.In addition,PAM also can reduce sticking risk,prevent leakage and collapse.
2.Used as displacement agent Polyacrylamide can adjust the injected water's rheology properties and improve the viscosity of driven solution, make better the efficiency of spread etc.Adding a certain amount of high molecular weight polyacrylamide into injected water to increase viscosity and improve oil-water mobility ratio. |
