METHOD OF DEVELOPMENT OF HYDROCARBON DEPOSIT Russian patent published in 2009 - IPC E21B43/16 E21B43/26 

FIELD: oil and gas production.

SUBSTANCE: invention refers to oil and gas industry and can be implemented at completion stage of development of massif and strata-massif deposits with top of great thickness and with stretched bottom water actively penetrating into producing part of reservoir. The essence of the invention is as follows: the method consists in boring a horizontal well, in perforating it, in forming fissures by means of hydro-break of the reservoir performed in succession starting from the further from vertical section of the well end by means of insulating each perforated interval with a packer from the rest of the column; in successive building up value of break pressure starting from the further end of the well from minimal possible calculated value to maximal possible value; and in successive operation of the horizontal well via fissures of reservoir breaks. According to the invention at development of the deposit with active bottom water and inflow of oil and gas packers for insulation of perforated intervals are lowered on a flexible tube. Hydraulic break of the reservoir and preparing-completing operations for pumping proplant designed to fix break fissures in open position and to wash out residues of proplant upon completion of hydraulic break are carried out as one cycle by transferring the flexible tube along the horizontal section starting from the further end. Also maximal pressure of break is accepted as value not exceeding maximum permissible value for destructing rock skeleton of the given reservoir. Development of the deposit is executed with depressions on the reservoir eliminating drawing of bottom water.

EFFECT: facilitating maximum possible extraction of oil and gas from hydrocarbon deposit.
