METHOD OF INTENSIFYING OIL AND GAS RECOVERY Russian patent published in 2002 - IPC

FIELD: oil and gas producing industry. SUBSTANCE: method includes control over parameters of production process, performance of geological and engineering measures taken on basis of data of control over parameters of production process and aimed at action on formation for increase of fluid inflow. Action on formation is effected in process of fluid recovery by varying in geological and engineering measures of production, process parameters and continuous control of said parameters. Its is executed under automatic regime. Parameters of production process are taken and they are of most importance for increase of fluid inflow such as pressure of well fluid, temperature, moisture content and fluid density. Parameters are fixed with dynamics of their variation depending on rotation speed of electric motor. Said parameters of production process and value of fluid inflow are adjusted through control unit, and optimal values are maintained by variation of rotation speed of electric motor. Time of termination of geological and engineering measures is determined by moment of optimization of production process parameters and value of fluid inflow. For possibility of action of production process parameters on formation, system of feed and system of suction are connected by upper and lower holes in tubing string and separated from formation zone by packer. EFFECT: increased recovery of oil and gas, optimization and automation of process. 1 dwg
