陆梁油田西山窑组一段油藏储集层地质建模及应用

Reservoir Geological Modelling and Its Application of the First Member of Xishanyao Formation in Luliang Oilfield

陆梁油田陆9井区西山窑组一段为以构造控制为主、局部受岩性影响的底水油藏,通过试油试采和开发试验,油藏表现出供液能力和含水率平面差异大、纵向油水分布复杂的特点。为落实可供开发的有利部署区,亟需开展精细三维地质建模研究。基于岩心、测井、试油试采等资料综合研究成果,以Petrel建模软件为载体,建立研究区三维精细地质模型,落实油层及相关储集层参数的空间展布特征。根据模型预测结果,优选岩性和物性均较好的优势储集层区域部署开发井。经检验,地质模型与实际资料较吻合,为油藏开发部署提供了依据。

The first member of Xishanyao formation(J2x1)in Wellblock LU9 is a reservoir with bottom water,which is mainly controlled by structure and affected by lithology in local areas.The results of formation test,production test and development test have proved that the reservoir has liquid producing capability,the lateral water cut is very different and the vertical OWC is complicated.In order to determine favorable development areas,it is urgent to conduct a research on fine 3D geological modeling.Based on the data of core,well logging,for⁃mation and production test and using Petrel modeling software,a 3D fine geological model was established to determine the oil layers and the spatial distribution of reservoir parameters in the study area.And according to the prediction of the model,favorable reservoirs with good lithology and physical properties were selected to allocate development wells.The fine geological model has been confirmed consistent with the real data,which provides a reliable basis for reservoir development and well allocation.
