摘要
岔河集油田位于冀中霸县凹陷西侧岔河集构造带,是华北油田典型的复杂断块砂岩油藏,该油田已进入中高含水期,调整挖潜难度亦逐年增加。综合运用地震、地质、测井、分析化验、开发动态等资料,按照二次开发的理念优化设计开发方案,对全区油藏特征进行了综合描述,并对剩余油进行了预测;采用三角网格计算方法及断层全部或部分阶梯化的方式,有效解决了断层间复杂的交切关系,建立复杂断块整体地质模型,为数值模拟及开发调整提供可靠地质基础。该成果在岔河集油田得到了成功应用,实现了开发区带整体研究与重点区块精细刻画的统一。
Located in Chaheji tectonic belt,the west of BaXian depression in central Hebei province,Chaheji oilfield is a typical complex fault block sandstone reservoir.The oilfield has entered high water cut period and the difficulty on adjustment and exploitation also increases year by year.By integrated use of seismic,geology,logging,testing and development of dynamic information data,highlighting the integrity of the study and the combination of dynamic and static data,an outstanding fine geologic modeling and remaining oil quantitative description,etc have been applied.According to the concept of the secondary development of optimization design and development plan of work,the application of advanced technology initially formed technology development zone with fine reservoir description research process,which made significant breakthrough in reservoir.By the use of Triangular grid computing method and the fault of all or part of the ladder,effectively solve the complex intersection relationship between the fault and complex fault block,the whole geological model is set up,which provides reliable geological basis for the numerical simulation and development adjustment.The successful application of the achievements in Chaheji oilfield indicates the unity realization of development zone and the key blocks description of the whole research,and its technical breakthrough will provide technical reference for the implementation of the 'secondary development' complex fault block of Huabei oilfield.
