Title:
OUTPUT INCREASING SYSTEM AND OUTPUT INCREASING METHOD FOR INJECTING INTERNAL COMBUSTION ENGINE TAIL GAS INTO OIL AND GAS RESERVOIR
Document Type and Number:
WIPO Patent Application WO/2018/153142
Kind Code:
A1
Abstract:
Disclosed are an output increasing system and an output increasing method for injecting internal combustion engine tail gas into an oil and gas reservoir, the system comprising a ground pressure boost unit and an underground output increasing unit.The output increasing method involves using a driving internal combustion engine of the ground pressure boost unit to drive a driven internal combustion engine to boost the pressure of high temperature tail gas, and injecting the high temperature tail gas into an oil and gas reservoir by the underground output increasing unit to perform heat exchange or a physical or chemical reaction with underground oil, gas, water and rock to perform tail gas throughput or tail gas drive, so as to increase the pressure, temperature and permeability of the stratum and the flow rate, outputs and final recovery ratio of oil and gas. At the same time, the tail gas component, thermal energy, pressure energy and the like produced by the internal combustion engine in the whole process are completely reused, without excessive tail gas emissions into the atmosphere, making the process highly efficient, energy-saving and environmentally friendly. The system and the method further have the advantages of withstanding high temperatures, withstanding high pressures, resisting corrosion, having a simple structure, being easy to realise and being low cost.
