SZ开发区特高含水期水驱开发规律研究
|
摘要
当油田开发进入了特高含水开发阶段以后与中低含水开发阶段相比,特高含水期油藏具有采油速度低、耗水量大、剩余油更加分散、措施效果变差、井况恶化、开发经济效益下降等开发特点,需要对特高含水期水驱开发规律进行研究。
SZ开发区经过47年开发,目前已进入特高含水期产量递减阶段,油田开发面临着高含水、高采出程度、高递减的"三高"局面。目前油田综合含水已达到91%,从水驱开采状况来看,措施增油效果逐年变差,各套层系间含水差异只有3～4个百分点,结构调整的余地已经很小,综合调整的难度明显加大。因此需要通过岩心驱替实验及矿场资料统计分析,对SZ开发区特高含水期含水上升规律、产量递减规律、递减率与储采比的关系、分层系开发规律、油田开发规律的影响因素等方面进行研究,为SZ开发区进一步持续有效开发提供理论基础。
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. Therefore, the core displacement experiments and the field data analysis are needed to study the water-drive laws of the high water cut stage reservoirs in SZ zone.
