Formulation Of South West Oil Layered Beam

With the continuous improvement of reservoir fine management level, to meet the needs of different reservoir of energy, the different layer series of development, adopt the layered water injection technology stratification complement formation energy.This paper studied lots of literature data, conducted a number of field research, combined with existing technology status at home and abroad, analysis of layered water injection status, the principle of bridge eccentric, concentric technology combined with the Wu 22-11 well injection profile logging diagram and Changqing Oilfield two plant oil field in 2009 and in 2014 the South beam field data, realize the importance of bridge concentric distribution in oilfield water injection development, is to solve the eccentric separate injection technology in deep wells, high angle wells, severe scaling well test success rate and the low efficiency problem, and further improve the injection well testing and adjusting technology, improve the success rate and efficiency of adjustment, to meet a new separate layer water injection technique refinement water requirements of oil field development and the development of the. We on the existing in the use of engineering problem, has made the improvement, further enhance its further enhance its measuring and adjusting the success rate, efficiency and success rate of sealing test. Southern Liang oil after using bridge concentric zonal injection technology, in water injection intensity and relative water absorption rate, the absolute amount of water absorption has been greatly improved. In the specific field data combined with the South beam oil in recent years and can be found in decreasing concentric distribution on bridge oilfield energy conservation and use of water flooding condition, stability, oil yield delay has very good effect.
