method of forming a bed of long channels and the filtration system in geophysical research and device for its implementation

摘要

the invention relates to the oil industry and can be used in the secondary opening productive reservoirs through a system of long channel filtering, recovery of oil and gas wells and the establishment of u043fu0435u0440u0444u043eu0440u0430u0446u0438u043eu043du043du044bu0445 openings in the casing string.the essence of the invention: in accordance with the mode set to the column lift pipes with the possibility of rotation and displacement u043eu0441u0435u0432u043eu0433u043e u0441u043au0432u0430u0436u0438u043du043du0443u044e layout (uk)a guide shoe with curved channel for movement therein, a sleeve of high pressure (u0440u0432u0434) with at least one head and mehanni u0437u043c forming holes (ifis) in the casing string (s) for the coincidence of output channels shoe and ifis and the integrity of u043eu0441u0435u0432u043eu0433u043e distances between do their exit openings; the uk down the preset depth and setthrough the pipe anchor ok; produce the geophysical instrument, determining the spatial position of output channels of the uk, according to which p u0440u043eu0438u0437u0432u043eu0434u044fu0442 twist scs in the situation.the exit hole is installed in a u0430u0437u0438u043cu0443u0442u0430u043bu044cu043du043eu043c ifi direction; after extracting the geophysical instrument in the borehole to reveal the ifis ok with the formation of the first openings; produce a sc and establish the exit wound ifis in the next set u0430u0437u0438u043cu0443u0442u0430u043bu044cu043du043eu043c direction on one u0443u0440u043eu0432u043d e without moving the column lift pipes in wells and the complement of au0435u043bu044cu043du044bu0445 u0441u043fu0443u0441u043au043eu043fu043eu0434u044au0435u043cu043du044bu0445 operations; forming the hole in the fine control of cutting tool; after the formation of the holes in the well without the of u0441u043fu0443u0441u043au043eu043fu043eu0434u044au0435u043cu043du044bu0445
