SYSTEM DEVELOPMENT OF MULTI-LAYER unproductive oil reservoirs

摘要

Development System unproductive multilayer oil reservoir, comprising extracting splitters fan wells, horizontal sections which in the reservoir are directed symmetrically in radial directions relative to the main stem, and vertical injection wells arranged on a uniform square five-spot pattern waterflood, characterized in that the main wellbore terminates above producing formation roof and sidetracks are productive in the formation at the inclination angle close to ulyu intersect the reservoir throughout its depth to the producing formation of the sole, followed by gently sloping upward trunk portion which terminates at the producing formation roof liquid selection produce simultaneously two lateral holes arranged symmetrically with respect to the main wellbore during the operation of fan wells is carried out insulation layers developed.
