喇嘛甸油田北东块位于油田北东部,开发面积0.36km2。北东块葡Ⅰ1-2油层纯含油面积14.9km2,平均有效厚度12.3m,中部深度为930~1220m。该区块96年7月开始注聚,2000年11月全部转入后续水驱。目前全区含水为95.9%,日产油只有929t,已进入后续水驱特高含水阶段。为充分利用油田的天然气资源,探索厚油层内部剩余油挖潜的有效方法,我们开展厚油层注气提高采收率可行性的数值模拟研究。
Lamadian North Block is located in the eastern part of the oilfield, the development area of 0.36km2. North East Block Pu Ⅰ Ⅰ -2 oil reservoir pure oil area of 14.9km2, the average effective thickness of 12.3m, the central depth of 930 ~ 1220m. The block began to gather in July 1996 and all went into follow-up water flooding in November 2000. Currently the region contains 95.9% of water, oil production is only 929t, has entered the follow-up water-flooding stage. In order to make full use of the natural gas resources of oilfields and explore effective methods for tapping the potential of residual oil in thick oil reservoirs, we conducted numerical simulations to investigate the feasibility of gas injection in thick reservoirs.
