摘要

the invention relates to the oil industry and can be used to enhance the recovery ratio by most of the reservoirs in the u043eu0441u043bu043eu0436u043du0435u043du043du044b the geological and mining conditions.a secondary opening productive reservoirs u0433u0435u043bu0438u043au043eu0438u0434u043du043eu0439 u043fu0435u0440u0444u043eu0440u0430u0446u0438u0435u0439 includes perforations which are moving along the axis of the bore perforator, and one rotate around its own axis for his education u043fu0435u0440u0444u043eu0440u0430u0446u0438u043eu043du043du044bu0445 channels, with the speed of movement and rotation of the u043fu0435u0440u0444u043eu0440u0430u0442u043eu0440u0430 choose on the basis of the conditions of the ithat the resulting perforation is a u0433u0435u043bu0438u043au043eu0438u0434u0443 education space is contained in the medium level, with a u043fu0435u0440u0444u043eu0440u0430u0442u043eu0440u0430 using the hydraulic u043fu0435u0440u0444u043eu0440u0430u0446u0438u043eu043du043du0443u044e spout (hydraulic perforator) and step by u0433u0435u043bu0438u043au043eu0438u0434u044b is 10 cm, and the step u0433u0435u043bu0438u043au043eu0438u0434u044b is 0.7 max u0438u043cu0430u043bu044cu043du043eu0439 height slits.pinhole channels are combined with each other in the reservoir, the small step u0433u0435u043bu0438u043au043eu0438u0434u044b and u0437u0430u043au043eu043bu043eu043du043du043eu043c space is formed cylindrical mountain u0432u044bu0440u0430u0431u043eu0442 a radius of more than 0.5 mm.the infiltration of liquid from a reservoir in the keyhole 5 times higher than for the open of the borehole, reducing the skin sensitive to the level of hydraulic ra u0437u0440u044bu0432u0430 reservoir without destroying the roof or bottom stratum or jumpers inside the reservoir.the invention provides an open shaft wells (cavity) to a radius of more than 0.5 m to reduce the filtration resistance, reduce the risk of "foot" in u0433u0438u0434u0440u0430u0432u043bu0438u0447u0435u0441u043au043eu043c fracture reservoir and improve the efficiency of filtering.
