Huanjiang Changqing Oilfield "double" Shu old jinlao
China oil network news as of November 21st, since the water shutoff wells River 71-55 wells at the end of April this year of completion, the accumulative oil has more than 1165 tons.
In order to curb the aging rate of the old oil field, Changqing oil recovery seven plant focuses on "tamping foundation, controlling water content, decreasing decline and raising level", increasing the "dual adjustment" intensity of injection wells. Oil production plant seven led the "double tune" management team, through the extraordinary equipment organization, rationalization design, fine site management and other work, and actively implement the "double 150" project (that is, water plugging profile control 150, microsphere profile control 150). Up to now, the oil production plant seven "double tune" work completed a total of 147 wells, water plugging and profile control completed 118% of the planned workload, 136% of the total capacity of the project, and the cumulative increase of oil reached 16 thousand tons.
In order to make the "double tune" work scheme and the reservoir temper, the seven oil production plant according to the geological structure of the actual, constantly refine the program design, and actively carry out the treatment measures. Technical personnel in accordance with the "point on the problem, looking for reasons on the spot" idea, take "overall control flooding, single point adjustment" way, carried out a total of 20 blocks of 323 wells corresponding injection wells water treatment control.
In order to ensure the effect of profile control and flooding, the reasonable technical parameters of technical personnel should be adjusted and controlled by formation pressure. Up to now, water shutoff and profile control have been completed 109 wells, corresponding to 449 oil wells, the cumulative increase of 10 thousand and 200 tons of oil; microsphere flooding has been completed 38 wells, corresponding to 600 wells, the cumulative increase of 6558 tons of oil.
In order to ensure the effectiveness of the program, the oil production plant seven constantly in the "double tune" on-site management efforts. Strict implementation of cadre partition contract system, groping in the actual work summary, in accordance with the construction progress of the implementation, completion and acceptance, approval, supervision and inspection of the "four in one" process monitoring and the mode of "5+10" (5 days a census, 10 day notification) strict operation management, multi frequency, full range to carry out on-site inspection. Up to now, a total of 20 copies of supervision were issued, and organized "double tune" regular meeting 9 times. At the same time, relying on the factory SCADA system to complete the 20 sets of "double tune" equipment digital transformation work, to achieve real-time monitoring of key parameters.
