摘　　要：用兰德马克公司VIP并行数模软件完成了大型的裂缝性特低渗透油田———新疆克拉玛依油田八区下乌尔禾组巨厚砾岩油藏的数值模拟研究。该油藏为带边底水非均质比较严重的双重介质油气藏,为研究合理井网井距及开发层系,提高储量动用的可行性,精细模拟该油藏,建立了近66万节点的双孔模型。由于缺乏裂缝模型,历史拟合过程中利用生产动态反映的规律反推了裂缝模型,这就需要进行多次的拟合,对如此复杂且规模庞大的油藏开展数值模拟,没有该并行软件将不可能实现。通过数值模拟研究,认为该油藏应细分层系进行开发,每套井网在合理采油速度下采用200m反九点注水井网,注采比不超过2。Parallel reservoir simulator VIP developed by Landmark has been used to perform the reservoir numerical simulation study in the giant fractured ultralow permeability oil field—the super-thick conglomerate reservoir of Lower Wuerhe Formation in District No.8 in Karamay Oilfield,Xinjiang,China.It is a heavily heterogeneous reservoir of dual porosity with edge-water and bottom-water. In view of the low degree of water-drive in water-flooding,poor effect of water-flooding in the reservoir,accurate numerical simulation was conducted and a dual porous model with nearly 660,000 nodes was established in the reservoir.In addition,due to the absence of fractured models,in the history of matching process,the law of production performance can be used to inverse fractured models,which requires multiple matching.It would be impossible to conduct numerical simulation in such complicated and tremendous reservoir without this software.By conducting numerical simulation study,it is considered that the reservoir should be developed under subdivided series of strata,while adopting 200m inverted nine-spot water-flooding well pattern at the proper oil recovery rate for each set of well pattern,with the ratio of injection to production no higher than 2.
