摘要(Abstract)：
杏北地区进入高含水后期以来,通过深化精细构造、储层研究,形成了一套适用的精细油藏描述技术,其成果在油田开发中得到广泛应用,取得了较好效果。在参数解释方面,通过研制新测井系列厚度解释电性标准,使油层划准率由76·5%提高到90·6%;通过研制“先定性、后定量”的新水淹层解释方法,使新测井系列水淹层解释符合率提高了16·7个百分点。在河流相储层描述方面,针对聚驱开采特点,开展了单一河道砂体识别和流动单元划分,在此基础上,通过单砂层沉积韵律相似性对比,进行了河道砂体内部隔夹层解剖,进一步揭示了河流相储层内部非均质分布特征。在三维地质建模方面,应用EV软件建立全区构造模型、通过研制接口程序,实现了应用EV、FCM、PETREL软件的联合相控建模,形成了一套适合杏北地区储层特点的三维地质建模技术,满足了多学科油藏研究的需要。
Since Xingbei area has entered into ultra-high water cut stage, a set of suitable fine reservoir description techniques have formed by deepening fine structure and oil layer research, and it has been widely applied in oilfield development with good effect. In view of parameter interpretation, by developing new logging series of thickness interpretation electric criteria, classifying accuracy of oil layer rises to 90.6% from original 76.6%. Additional, through developing new interpretation method of “first qualification and then quantification”for watered out zones, coincidence rate of interpretation for watered out zone in new logging series increases by 16.7%. According to polymer flooding characteristics, we performed identification of single channel sand and classification of flow units in the field of river facies reservoir description. On the basis of previous work, we dissect inter layers within channel sand by analyzing sedimentary rhythm similarity of single channel, further revealing heterogeneous distribution features in river facies oil layers. As for 3D geology modeling, structure model for overall block is built with EV software. With the assistance of interface development , application of jointly phase controlled modeling comes true with EV, FCM and PETREL software, forming a set of 3D geology modeling techniques suitable for characteristics of oil layer in Xingbei area, which can satisfy the study need of multi-discipline reservoirs .
