葡萄花油田北部地区压力系统的调整

PRESSURE SYSTEM REGULATION IN PUTAOHUA OILFIELD NORTHERN AREA

通过对葡萄花油田北部地区合理注水压力,合理流动压力和合理地层压力界限的讨论,初步确定了该地区合理的压力系统。经过一年多时间对压力系统的调整工作,取得了增加产量,稳定含水,改善油层动用状况的初步效果。

<ABSTRACT> Through discussions on the limits of reasonable water injection pressure, flowing pressure and formation pressure in the northern area of Putaohua Oilfield, the rational pressure system in this area was initially determined. Through the regulational work on the pressure system during the past more than one year, preliminary results in increasing output, stabilizing water cut, improving the draving conditions of the formations were obtained.
