喇嘛甸油田高含水后期多学科油藏开发研究
|
摘要
喇嘛甸油田经过三十余年的开发,已进入特高含水阶段。目前,在油田开发上主要存在的问题是:油田综合含水高、主力油层储量动用程度高水淹厚度大、剩余油分布高度分散、无效或低效注水循环严重、平面矛盾和层间矛盾突出。以上问题和矛盾使得油田调整挖潜的难度加大、成本投入逐年增多,常规的剩余油分析和判断方法已不适应目前的油田开发现状。为探索油田开发的新途径,寻找特高含水阶段油田剩余油分布特征,开展了多学科油藏研究与现场试验。多学科油藏研究在西方已经成为油田开发的常用技术手段,以油藏精细描述及剩余油分布研究为核心内容,通过开展精细地质研究、地质建模、油藏数值模拟、经济评价和方案设计等,并把这些研究成果有机地结合起来,使油藏描述更加准确,挖潜措施更具有针对性、更符合油田开发现状,以最小的成本费用获取最大的经济效益。为取得最大的研究、试验效果,选取了喇嘛甸油田南部地区作为多学科油藏研究区块,把多学科、多专业结合起来,开展研究,为特高含水期区块综合调整挖潜摸索出一条新路子,同时,也为现代化油藏研究与管理开辟新的思路。
Lamadian oil field has come into specially high water cut period after 30year’s developing. Now, the development problems lie in that the overall water cut is high, the employed extent of major reservoir and the depth of water-out zone is also high, residual oil distribution is highly dispersive, the invalidity and low-efficiency of water injection recycle is serious, plane contradiction and interlayer contradiction is prominent, the above problems and contradiction make oilfield’s integrated adjustment and tapping potential become more difficult, and invested cost increase gradually every year, so conventional residual oil analyze and judgment method haven’t been fit for the present situation of development. In order to explore the new way of development, and find the distribution characteristics of oilfield residual oil during the specially high water-cut period. We carry on multidisciplinary reservoir research and pilot tests. Multidisciplinary reservoir research has become an usual method in the West, and its key contents are fine reservoir description and the study of residual oil distribution. By means of carrying on fine geology research, setting up reservoir numerical simulations, economic evaluation, program design, and organically combining these study’s results, we can get the more accurate reservoir descriptions, the fitter situation of oilfield development, and the highest economic benefits at the lowest cost. With the aim to get the best study and trial results, we choose the south of Lamadian oilfield as the region of multidisciplinary reservoir study, combine the multidisciplinary and multispeciality to research, and we explore a new way to integrated adjustment and tapping potential of specially high water cut block, at the same time, a new train of thought for modern reservoir study and management.
