Filter is equipped with safety valve, operation of which is provided when filter is filled with proppant and mechanical impurities from pressure drop inside and outside the filter. Formation fluid is passed to intake of downhole pump past filter by channel in safety valve opening from pressure drop. Further, centrifugal or other type bottom-hole pump is lowered into the well and work is carried out for recovery of formation fluid as per standard technology. Autonomous filters, as well as packers or sealing cups are made of easily drilled materials soluble in acids and / or alkalis, for example aluminum or aluminum alloys. If it is impossible to remove the layout from for replacement of filters or face washing, autonomous filter or filters, packers or sealing cups are drilled out. In case of complications with drilling, acid or alkali is pumped to the well depending on the selected material of autonomous filter and packers or sealing cups. In both cases, proppant, mechanical admixtures, remains of drilled out parts of the assembly, chemical reaction derivatives are placed into the sump of the well, from which they are removed by standard technology.

Abstract: FIELD: radio engineering.SUBSTANCE: invention relates to the field of radio engineering and can be used to measure two-dimensional coordinates of a ground target by the goniometric-rangefinder method by a radar system consisting of a multi-beam transmitter with known coordinates, emitting encoded radar signals in specified directions, and a direction finder receiver with known coordinates, receiving signals reflected from a ground target, which determines the direction to a ground target and measures the distance direction finder - ground target - transmitter. In the claimed method, a radar system consisting of a direction finder receiver and a multibeam transmitter is emitted in the directions ϕn, (n=1, 2, …, N) by a transmitter with known coordinates х1, y1of coded radar signals with its own code for each direction, which are scattered by a ground target with the desired coordinates x, y and are received by the receiver with known coordinates xt, yt, synchronized with the transmitter. The distance R transmitter - ground target - receiver is measured, the directions ϕntransmitter - ground target are determined by the radar signal code, and then the boundaries of the search area for coordinates x, y of the ground target are determined. The search area is limited by a straight-line segment determined by the intersection of the boundaries of the beam ϕnwith the bearing line to the ground target ϕt. The coordinates x, y of the ground target are determined by testing hypotheses about the location of the ground target at each point in the search area, while the criterion of the working hypothesis is the minimum difference between the measured distance R and thetransmitter - hypothetical ground target - receiver distance.EFFECT: reduction in the number of tested hypotheses by reducing the region of uncertainty when searching for estimates of the coordinates of a ground target.1 cl, 3 dwg
