METHOD FOR DEVELOPMENT OF OIL FIELD WITH ABNORMALLY LOW FORMATION PRESSURE

摘要

Summary of the invention: prior to operating the drilling sequentially pumped into the formation dioxide and water in an amount sufficient to increase the pressure to the hydrostatic liquid column. The proportion of gas is 0.5-0.7, and the proportion of oil - 0.3 to 0.5 of the total injected agent.
