China oil network news August 3rd, North China Oilfield five plants for water as high as 100% and the long-term shutdown of the Jin 105-46X well, in the implementation of "plugging mining under water plugging measures" after seeing the obvious precipitation effect of oil production, Nissan liquid by the 31 cubic meters to 25 cubic meters, Nissan 9 tons of oil, to identify the root cause well, the resurrection of potential reservoir.
Jin 105-46X wells production formation 57-63 Shahe Street No. three section, that the dynamic analysis of scientific and technical personnel, the upper part of the reservoir of No. 57 layer is the main production layer, pressing the lower reservoir, resulting in high water cut oil well plugging, put forward 57 main production layer, thereby inhibiting the contradiction between layers, the lower reservoir production.
In this regard, the five production factory technical personnel on lowering the efficiency of the center, with "plugging, reservoir protection, convenient construction, low cost" as the goal, process optimization measures, fill in the sand cement injection protect the lower oil layer on the application of sealing reliable strength, chemical stability properties of thermosetting resin plugging agent, one-time sealing of layer 57, the short-term effective measures to achieve.
