FIELD: oil extractive industry, possible use during extraction of oil deposit in heterogeneous collector of low thickness. ^ SUBSTANCE: in accordance to method, in heterogeneous collector of low thickness at least one well is driven to productive formation, horizontal section exits into formation. After exit to formation horizontal section of well is driven in wave-like fashion from shoe through the middle towards the ceiling of formation and back from the ceiling through the middle towards the shoe of formation with repeat of waves across the formation. Tubing column is lowered into well and let out into productive formation. In productive formation, product and force wells are driven in similar fashion. During operation of well as product well, liquid is taken in across whole well profile: from shoe, middle and ceiling sections. During operation of well as force well, forcing of working agent is performed across whole profile of well: into shoe, middle and ceiling sections of bed. ^ EFFECT: increased oil recovery of deposit. ^ 1 ex |
