Increasing the Effectiveness of the Complex Hydrogen Thermobaric Chemical Effect Technology for Stimulation of the Production of Hydrocarbons by Using Polymer Paracyanogen

Abstract

The research is focused on increasing the manageability and effectiveness of the technology of complex hydrogen thermobaric chemical effect (CHTBCE) to increase the production of hydrocarbons from oil and gas wells. It is demonstrated that the basic chemical-technological process of this technology is ineffective because both the temperature level and the duration of its high-temperature stage are insufficient for generating hydrogen and effecting partial hydrocracking of heavy hydrocarbons. This limiting stage of the process can be overcome by using the physico-chemical activation technique. Experiments have demonstrated that these problems can be solved by adding polymer paracyanogen to the composition of basic process fluids as a combustion activator. The dispersing and the mechanochemical activation of paracyanogen into a particle size range of 1-5 μm, combined with simultaneous homogenization of the "activator-liquid suspension medium" system, were conducted using the hydrocavitation activation method. Experiments have shown that the optimal amount of 0.7% to 0.95% mass of paracyanogen as a combustion activator in process fluids can increase and sustain the temperature level during the high-temperature stage of the process. This can be sufficient for generating hydrogen from hydroreactive agents to effect the process of hydrocracking heavy hydrocarbons.
