摘要
SK油田地层能量下降,2007年始产量迅速递减,含水率持续上升。为改善此现象,油田展开基础研究,深入研究剩余油分布规律,部署一批加密和完善井,调整注采井网,提高了储量动用程度和水驱控制程度。在改变思路的同时加大措施力度,增油比例得以提高。实施改进后油田产量下滑趋势得到遏止,产量得以恢复到峰值,储量采出程度提高。
With the incensement of oil recovery rate, the formation energy decreases into a serious deficit and theoutput had a plunge in 2007. The water cut keeps growing which made the development situation is not optimistic.The distribution pattern of the residual oil is analyzed, a number of infill and completely penetrating wells are de-ployed, the flooding pattern is modified, the reserve production development and the water drive control is im-proved, measures have been taken to prevent the field output from dropping. All these research is well applied ingood effects and increasing of oil production. The horizontal well technology is introduced to improve single welloutput in regions of good physical property of reservoir. Within 2 years, the output restored to its summit. The de-velopment effects are enhanced and the exploitation degree of reserves is increased.
