塔河1区三叠系下油组油藏精细地质建模
|
摘要
塔河1区三叠系下油组油藏属大底水、薄油层、受构造控制的砂岩孔隙型块状底水未饱和油藏。目前存在的主要问题是生产井普遍见水,含水上升过快、递减加大,水平井产液剖面出现异常,油藏总体动用程度偏低,高含水后治理难度增大,堵水措施有效率低,对油藏开发带来了严重威胁。因此有必要加强底水油藏地质特征的认识,进行油藏精细描述,建立适应油田开发调整的三维地质模型,从而为油藏数值模拟打下良好的基础。该区块的地质建模过程,采用目前较为先进的Petrel软件,充分利用钻井、地震、测井、地层对比等信息,结合夹层解释结果,在孔渗曲线的基础上,采用夹层建模和随机建模相结合的建模方法,通过对各种随机模型的对比评价分析,建立了接近油藏实际地质特征的三维精细地质模型,从三维空间上识别出夹层的类型、厚度和分布,认为塔河1区三叠系下油组油藏主要受到断层和夹层控制,这为开展底水水侵模式研究打下了一定基础。
The reservoir of the 1st block of Tahe Oilfield is one with a complicated fault system and edge-bottom water in the lower section of the lower oil formation. At present, the main problem is the breakthrough water in production wells. Water volume is increased too fast with over -declined oil volume. Production fluid lateral section of the horizontal wells sees abnormal features. The overall production level of reservoirs declines. The treatment is difficult to find in the high water stage, and it is not very effective to block water. All above factors pose a serious threat to reservoirs. Therefore, it is necessary to study geologic characteristics of edge -bottom water reservoirs with a 3D geologic model. Petrel software is used for the 3D geologic modeling of this block, with a full use of data related to drilling, seismic conditions, well log and stratigraphic correlation as well as interbed's explanation and poroperm curve. Among various stochastic models, a 3D geologic model is chosen, which is close to the actual geological conditions. The type, thickness and distribution of interbed are identified in 3D. It is concluded that the reservoir of the 1st block of Tahe Oilfield is controlled by fault and interbed, which may serve as a geological basis for further studies of water invasion patterns.
