Abstract: FIELD: oil industry. SUBSTANCE: each well is put in test operation after oil pool is drilled out by a set of wells, and permeability of collector and its anysotropy are determined. Size of helium screen is measured close to gas-oil contact accounting with these factors, as well as viscosity of gel after gel-forming, time of gel-forming and speed of drilling gel-forming solution down. Time of gel-forming and viscosity after gel-forming would be no less than period of time and value of viscosity to provided creation of gas and oil proof screen at area of gas-oil contact at lower boundary at interval from gas-oil contact to point where liquid is sampled; condition of non-leaching of gel-formed is provided at liquid sampling. Pipe string provided with packer is lowered into well at the level of initial oil-gas contact. To create proof screen the gel-forming solution is pumped down into gas-saturated part of the seam along the space being behind the pipes and higher than gas-oil contact is disposed. After preset volume of gel-forming solution is pumped down and during process of gel forming, the process is changed to pumping water down to get water barrier. Moreover, water is pumped down by means of the same perforation holes with intensity no lower than intensity of liquid sampling which is carried out after gel-forming process is finished. Oil production is accomplished with process of pumping water down along space behind pipes into gas-saturated area of seam. Pool is drilled by a set of wells with several horizontal shaft. Single shaft at least is drilled at the area of oil-saturation and liquid is sampled through it. The other shaft is drilled in parallel to the first one at gas-saturated area of the seam above gas-oil contact, and gel-forming solution and then water, are pumped down through the second shaft.
