Title: Method for development of oil-gas deposits
Inventor: ZAKIROV SUMBAT NABIEVICH
IPC: E21B43/20
Filed: 1996-02-05
Granted: 1998-04-20
Abstract: FIELD: oil and gas production industry. SUBSTANCE: method for development of oil-gas or gas-oil deposit implies drilling of horizontal wells, opening of productive collecting reservoirs and recovery of oil from boundary areas. With aim of increasing current oil outputs and final oil recovery, operation of all wells initially is performed in mode of exhausting reservoir energy and oil recovery at critical gas-free outputs. Control is effected of current gas-free oil output for each well. When output reaches 10-40% of its initial value, half of wells is transferred to fund of injection wells. Injection of water into oil boundary is effected at outputs which do not exceed fluid recoveries from producing wells. They ensure creation of required tense condition of oil boundary and corresponding increase of current gas-free outputs. Number of producing wells which are transferred to mode of injection wells corresponds to condition of maintaining bed pressure at level of initial pressure. Aforesaid method of development increases current oil outputs throughout wells and improves final coefficient of oil recovery at conditions of retaining gas cap energy. EFFECT: higher efficiency. 2 tbl, 1 dwg

Granted: 2000-05-20
Abstract: FIELD: technical cybernetics, computer engineering. SUBSTANCE: method involves continuous monitoring of pressure, temperature and usage of components of fuel that enter engine and rotation of shaft of turbine pump after engine reaches main traction stage mode. In addition, method involves detection of value of cavitation pressure tolerance, and continuous comparison of resulted value to tolerant level. When cavitation pressure tolerance drops below threshold, method involves regulation of through section of regulation unit, switching engine to mode at which pressure that corresponds to beginning of cavitation break of pump is decreased and cavitation tolerance of engine is increased. Stability of engine to side and cavitation oscillations in pressure is increased by means of analysis of frequency and amplitude of pressure oscillations at entrance to engine. If oscillations develop (their amplitude is increased), method involves setting through section alteration of regulation unit towards operation mode that provides quenching of self-oscillations. EFFECT: increased efficiency due to decreased pressure in rocket tanks and possibility of engine operation upon faults in supply and temperature-keeping systems. 2 cl, 1 dwg, 2 tbl
