FIELD: mining industry. SUBSTANCE: method relates to testing of holes drilled for oil and gas and allows for better clearing of down-hole zone of reservoir, for increasing its permeability and hydraulic conductivity by way of high depressions in pumping out reservoir fluids and acid treatment which are performed in several cycles. According to data resulted from two running-downs of bed testers with similar periods of inflow T, determined are hydraulic conductivity of reservoir down-hole zone after action of depressions and acid treatment according to following formula:, by means of iterating calculations at similar values of first underlogarithmic expression. Then evaluated is efficiency of clearing down-hole zone of reservoir according to changing its hydraulic conductivity, and conclusions are made about further plan of intensifying inflow, where: B - volumetric coefficient of reservoir fluid, r•hK(β+β) - depression of reservoir pressure, T - inflow time, ΔP - product of effective thickness by effective porosity of reservoir, r - radius of bore-hole, βиβ- compressibility of reservoir liquid and reservoir pores. EFFECT: high efficiency. |
