Description

1. Technical field: [0001] The invention relates to a circuit for outputting a stable direct-current electric field, in particular to a 150V stabilized direct-current power supply circuit in a method for improving oil recovery by a direct-current electric field. 2. Background technology: [0002] The use of DC electric field to enhance oil recovery is a new oil recovery technology in recent years. Since the shortage of crude oil resources is a major problem faced by countries all over the world, enhanced oil recovery is an effective way to alleviate this problem. However, as the medium and high permeability reservoirs have successively entered the high water cut period, fracture-karst cave type low permeability reservoirs have become the main bottleneck of oil production. Using conventional oil recovery methods to deal with fracture-karst cave type low-permeability oil layers, the oil recovery rate is low, and nearly 50-70% of the crude oil cannot be recovered. Therefore, ...
