A Study On Artificial Earthquake Oil Recovery Disturbance System And Technology

Enhanced oil recovery with artificial earthquake is a physical oil recovery method which has several advantages such as no pollution, low cost, high return, relatively simple technology and has a good application prospect to improve oil recovery. At present, most of studies about this technique still remain in qualitative level, which can not project the optimum debug parameters of artificial seismic source system and the best construction parameters according to the specific situations with reservoir and oil well. Therefore, people can only project and construction according to their experience during field operation, so it is hard to ensure that this technology process measures to achieve the best effect.Using the dynamic simulation device of enhanced oil recovery with the wave field, this paper evaluated artificial earthquake oil displacement effect and the main influence factors. On the basic principle of dynamic, it analyzed the movement laws of the main parameters of artificial earthquake seismic source under the movement process; and studied the wellbore wave field on the influence laws of near wellbore formation reservoir parameters. Finally it summarized the on-site construction processes of artificial seismic source well and the optimal debugging method about artificial source system, which offer scientific theory for this technology in field application.It optimized the design of operational procedure, method of construction and the debug parameters of artificial seismic source system on Feng1231well. At the same time carrying out field test for six months, which indicated that enhanced oil recovery with artificial earthquake has higher economic benefit for high-water-cut in complex oil field exploration.
