METHOD OF DEVELOPMENT OF HYDROCARBONS DEPOSIT

FIELD: oil and gas industry. ^ SUBSTANCE: invention relates to development of non-uniform hydrocarbons deposit. The essence of the invention is as follows: according to the method a displacement agent is pumped into pressure wells and production is withdrawn from producing wells. On base of injection capacities of displacement agent and production watering parameters of wells operation are analyzed. Pressure wells with non-uniform capacity and producing wells with watering of production above the established level are chosen. There pumped into pressure wells water solution of "±-", alternating solutions of "±-" and water solutions of calcium chloride with consumption 0.3-0.6 m3 per 1 m of horizon thickness providing formation of a plastic sedimentation in this horizon at their interconnection in the horizon, preventing absorption of well and additionally of insulating material from not-reacted portions of the said water solutions at gas or horizon waters breaks-in. Further fringes of water solutions of alkaline drain of caprolactam production -ADC- of concentration not less 10% are pumped. At that pressure of pumping is raised by 2-5 atm at every 2-5 m3 of pumped components water solutions. ^ EFFECT: upgraded efficiency of method. ^ 5 cl
