SUBSTANCE: group of inventions relates to oil and gas industry, in particular, to remedial cementing at recovery of casing strings tightness. Method involves covering the leakage zone from inside with a deformed pipe as a casing patch liner, and its expansion along the whole length by creation of water excess pressure. Deformed pipe used is in fact a shaped pipe with cylindrical ends plugged on the extreme ends. Upper cylindrical end of the pipe together with the conical section are separated after expansion of the deformed pipe creating excessive pressure inside the pipe, which exceeds the pressure to expand the deformed pipe. Lower cylindrical end of the pipe together with the conical section are separated after separation of the upper cylindrical end of the pipe together with the conical section from the extended pipe by deforming the lower conical section and moving this section together with the lower cylindrical end of the pipe upward. On the outer side wall at both ends of the shaped part of the pipe a closed slot is made located in the plane perpendicular to the shaped pipe axis. Upper plug has the shape of a cap with a central hole, two eccentric holes and internal taper thread on the side wall. Lower plug has the shape of a cylinder, on the upper end of which the lower end of a rod is rigidly secured, located with the ability of axial movement in the central hole of the upper plug. On the rod between the upper and the lower plugs, with the ability of axial movement, there is a two-piece gripper with wedges on the lower end spring-loaded by a compression spring. On the lower extreme end the two-piece gripper has a threaded recess, provided with a screw in the form of bushing. To the inner wall of the lower cylindrical end of the shaped pipe the lower rod end is welded, which upper end is fixed to the side wall of the two-piece gripper.
EFFECT: reduced time costs, preventing contamination of the well.

SUBSTANCE: invention can be used in developing heterogenous layered reservoirs. Method involves selection of producer and nearest injection well, which is reason of flooding of production well. Method includes pumping into well a composition for limiting water influx to eliminate water inrush zones. Water is pumped into injection well and product is extracted from production well. Composition for limiting water inflow is modified with water-water, concentration and ion composition of dissolved salts which is determined by laboratory research of reduction of permeability of core of given interlayer by not less than 10 times while pumping one porous volume of core at formation temperature and pumping rate of not less than 5 ml/min. Reduction of permeability is a result of precipitation of salts in bottomhole zone of production well during reaction of modified water with waste water of interlayer. Water cut of each interlayer is determined in production well. In injection and production well a string is lowered, having packers and said packers isolate interlayer with maximum water content from rest of interlayers. Modified water is pumped into isolated interlayer through injection well at a rate of 0.5-1.0 of maximum intake rate of interlayer. Bottom-hole pressure in production well is reduced to 0.9-1.0 of saturation pressure. Pumping is performed until water cut of interlayer is 0.8-1.2 of water cut of interlayer with minimum water cut. After that, through injection well in analysed interlayer aqueous solution of chlorine is pumped in amount of 20-100 m3 per 1 m effective thickness of interlayer. In first 10-50 m3 of injected modified water saline deposit inhibitors are added. Similar operation for successive pumping of modified water and aqueous chlorine solution is carried out on other interlayers except interlayer with minimum water cut. After that, wells are converted to normal operating mode. Said operations are repeated with periodicity of 0.5-2 year.
EFFECT: high uniformity of recovery of oil reserves, increasing sweep efficiency and oil recovery of layered oil deposits.

SUBSTANCE: invention can be used in development of anticline deposits of oil of water-oil zones and terrigenous type. Method involves drilling of deposit with water-oil zones of system of production wells. Said wells in upper part of productive formation are perforated for product extraction. Development is carried out in deposits with an anticline structure presented by terrigenous type of reservoir, in pores of which there are fine clay particles and not less than 50 % of said particles relate to kaolinite clays. After flooding by more than 98 % of one or more wells of first row located closest to oil-water contact, modified water is injected, where modified water in which concentration of NaCl is not more than 5 g/l and its effect on reservoir reduces water relative permeability by at least 5 times. Pumping is performed for 3-10 days with rate of 0.1-0.8 of maximum intake of said wells. Thereafter, said wells of first row are stopped. In adjacent production wells of second row, upstream of structural marks, modified water is injected for 5-15 days with flow rate of not more than 0.1 of maximum intake of said wells. Then after 1-10 days production begins in wells of second row. Processes of pumping modified water are repeated consecutively in direction from minimum structural marks to maximum with flooding of corresponding wells.
EFFECT: increasing oil recovery of oil deposits.
