A method for the development of oil pool with formation-pressure maintenance includes injection to ceiling section of the pool of nitrogen that is characterized with maximal pressure of mixing with oil. Extraction of crude oil is compensated with nitrogen that is injected in volumesaccording to the relationship,where- volumetric coefficient of crude oil, b/r;- extraction of degassed oil, th, t;- density of degassed oil, t/m;- strata and standard pressures, MPa;- strata and standard temperatures, K;- coefficient of super-compressibility of nitrogen atand, and crude oil is extracted from the middle section of oil deposit that is at distances from apical section of the deposit not less that half of thickness of oil-saturated section and not more than quarter of its thickness from water-oil contact. |
