井震结合储层精细描述在水平井设计中的应用

摘要

Relying solely on logging for inter-well reservoir prediction, there are many difficulties, and a large earthquake with a horizontal density advantages of using wells with inversion of seismic reservoir prediction tech-niques , can effectively improve reservoir prediction accuracy. Using this method blocks north of Daqing Changyuan development and application of detailed reservoir description and seen results, arranged according to sandstone in-version profile A-215 horizontal wells, the drilling rate of 92% sandstone, the cumulative oil production is currently well 9 686 t, showing a good prospect.%单纯依靠测井进行井间储层预测存在很多困难,而地震具有横向密度大的优势.采用井震结合反演技术进行储层预测,能有效提高储层预测精度.利用该方法在大庆长垣北部区块精细油藏描述及开发应用中见到实效,根据砂岩反演剖面布置了A -215水平井,其砂岩钻遇率为92％,该井目前累计产油9 686 t,展现了良好的应用前景.
