| 中文摘要: |
| 碎屑岩储层的内部结构控制着储层内的油水分布，对储层构型认识不清将严重影响后期的油气藏的开发。本文以四川盆地东峰场地区须家河组河口坝与渤海湾盆地埕岛油田馆陶组曲流河储层为例，充分利用地震、钻井、测井及岩心分析资料，提出了2种以水平井信息对构型单元进行识别的方法，进行了构型单元划分及定量表征。研究表明：基于水平井井震信息融合的构型单元识别方法利用高分辨率的波阻抗信息、随钻伽马、气测及元素录井数据对水平方向的构型单元进行综合识别，具有应用范围广泛、分辨率相对小的特点，在DF102HF井识别出4个单一河口坝及9个增生体；基于水平井成像探边测井的构型单元划分方法利用PeriScope工具探测到砂体的外部形态，结合曲流河沉积模式及随钻伽马曲线、随钻电阻率曲线对砂体内部夹层进行精细刻画，具有纵向分辨率大、准确度高、应用范围有限的特点，在CB251-P5井识别出3个边滩及5个侧积体。以上2种识别方法对于指导油气藏储层构型划分具有重要的参考意义。 |

| The internal structure of clastic rock reservoir controls the distribution of oil and water in the reservoir. Unclear understanding of reservoir configuration will seriously affect the development of oil and gas reservoirs in the later period. Taking Hekou Bar of Xujiahe Formation in Dongfengchang area of Sichuan Basin and Guantao Suite meanding river reservoir in Chengdao Oilfield of Bohai Bay Basin as examples， two methods of identifying configuration units based on horizontal well information are proposed in this paper， and their classification and quantitative characterization are carried out. The results show that the recognition method based on the fusion of well vibration information of horizontal wells uses high-resolution wave impedance information， gamma while drilling， gas measurement and element logging data to comprehensively identify the horizontal configuration units， which has the characteristics of wide application and relatively small resolution. 4 single estuarine bars and 9 accreting bodies are identified in the DF102HF well. The configurational unit division method based on horizontal well imaging edge logging uses Periscope to detect the external shape of the sand body， and combines meander river deposition mode with drilling gamma curve and drilling resistivity curve to accurately depict the inner interlayer of the sand body， which has the characteristics of large longitudinal resolution， high accuracy and limited application range. Three shoals and five lateral deposits were identified in well CB251-P5.The aforementioned two identification methods hold significant reference value in guiding the classification of reservoir configuration. |
