The Disciplinarian Research Of Water Driving In SZ Development Zone In The Period Of High Water Cut Stage

When the oil field development has entered the development of ultra-high water cut stage, compared to the low water content, The ultra-high water cut reservoir has some characteristics, such as, low production rate, large water consumption, more decentralized remaining oil, bad impact of the measures taken, deterioration in well condition, declined economic benefits. So, limits on the development of technologies need to be re-adjusted.The SZ zone has been developed for 47 years, and now it has entered the period of high water cut stage and decreasing production. The oil field development is faced with the "three-high" situation of high water cut, high degree of recovery, high-decreasing. At present, the oilfield comprehensive aquifer has reached 91 percent. According to the conditions of water flooding exploitation, the effects of measures to increase oil have been deteriorated year by year. The cut differences between the various layer systems have been only 3 ~ 4 percentage points. The room of structural adjustment has been very little. The difficulty for the comprehensive adjustment has increased.According to the mine core experimental data statistical analysis of actual data and theoretical analysis of reservoir engineering, we analyze the high water cut basic situation and development disciplinarian of the experimental area, SZ zone oil production decline rate and the change disciplinarian of production rate, and then analyze the high water single well measures of technical and economic limits to guide the production of oil next practical work.The development economy policy boundaries at the high water cut stage and the late high water-cut stage are fully summarized and analyzed. The development laws of the high water cut stage in SZ are grasped. Based on this study, whether the development economy policy boundaries at the late high water cut stage is applicable to the ultra-high water cut is studied. The development economy policy boundaries in SZ is studied to guide the next job of actual production using the application technology economic theory, reservoir engineering theory, material balance principles.
