Technology for realizing solid burying maximization and residual oil displacement by supercritically injecting CO2 (carbon dioxide) excessively into oil well

ActiveCN103277075Alarge capacityStorage status is stable
The invention relates to a technology for realizing solid burying maximization and residual oil displacement by supercritically injecting CO2 (carbon dioxide) excessively into an oil well. According to the technology, a high-pressure air pump, an injection well, an oil producing well, a blocking area, a crack seam, a break seam and a CO2 dispersionarea are adopted. The technology for realizing solid burying maximization and residual oil displacement by supercritically injecting CO2 excessively into the oil well is characterized in that the high-pressure air pump injects CO2 into a waste oil filed or an oil layer in an oil area under the supercritical pressure via the injection well, and thick, sticky and dispersed residual oil is displaced to be discharged out of the oil producing well by the aid of ultrastrong permeability, diffusivity and cleaning capability of CO2 liquid. Blocking materials are repeatedly injected into the injection well at intervals to block a smooth channel between the injection well and the oil producing well, the CO2 liquid is forced to disperse and pressurize to crack oil layer partitions and penetrate oil area partitions on the same oil layer, and thus the CO2 liquid is dispersed to all partitions, dead angles and blind areas. Compared with the prior art, the technology for realizing solid burying maximization and residual oil displacement by supercritically injecting CO2 excessively into the oil well has the advantages of thorough residual oil displacement, large capacity of solid-buried CO2, stable sealed storage, less air pollution, freedom of underground pollution, and environment-protection and emission reduction under the support of creating new benefits, so that the technology has great popularization and application values.
