FIELD: well drilling. SUBSTANCE: well part is intersected with natural proplastics in producing stratum. Shields are produced using insulating mixtures. These shields separate water saturated zones of the bed from oil saturated ones. Screen thickness is admitted on the base of natural insulation of the proplastic from developing stratum. Overall thickness of the shields is admitted on the base of resistance to pressure drop arising in well operation. EFFECT: high efficiency. 1 dwg
