INCREASE IN THE EFFICIENCY OF WATER SHUT-OFF WITH THE APPLICATION OF POLYETYLENPOLYAMINE ADDED CEMENT
As a result of intrastratal and interlayer flows of produced water of varying intensity, 25% of oil and gas wells are water-encroached in the world. Due to behind casing flow during the operation of oil and gas wells generally reduces the field's development efficiency. In the study, 1-6% (weight) polyethylene polyamine (PEPA) was added to the water in which the cement mixture will be prepared. The temperature dependence of the beginning and the end of the setting time of the obtained cement mortar was determined. Also, the adhesion properties of the cement mortar, the dependence of the strength to bending and compression on the dose of polymer were examined. It found that cement stone made of mixing cement with an aqueous solution containing 1-4% PEPA had high elastic properties. In addition, the presence of 2±1.5% PEPA in the specified amount of tampon solution increases the strength and to depressions of cement stone, improves adhesion properties.
