METHOD FOR OIL PRODUCTION FROM LOW-PERMEABLE RESERVOIRS

摘要

FIELD: oil production of viscous-oil reservoirs having low permeability.;SUBSTANCE: method involves drilling well to reservoir roof; providing well with casing pipe; lowering explosive charge in well; blasting explosive charge opposite to productive reservoir and creating caverns and fissures extending in radial direction from well. Explosive charges are lowered in wells of deposit development member wells drilled so that they are spaced a distance smaller than production reservoir depth between injection and producing wells. Caverns created in reservoir extend from wells in radial direction. Large explosive charge is additionally lowered in injection well for said explosive charge blasting opposite to productive reservoir to create pocket and fissure system, which connects injection and producing wells of the member. Member wells are brought into operation up to deposit resource depletion. Wells of adjacent members are operated in the same manner.;EFFECT: increased production intensity, extended reservoir coverage with treatment and improved oil extraction due to fissure system creation in productive reservoir zone between injection and producing wells.;1 ex, 1 dwg
