摘要
秦皇岛32-6油田和绥中36-1油田都属于低压稠油油田,储层岩石胶结疏松,孔隙度高、渗透率大,油井出砂将成为贯穿油田开发生产过程的主要问题,防砂则为开发生产及油层保护的重点。经研究决定采用下套管注水泥固井并在射孔套管内进行井下砾石充填的完井方案,因此射孔参数及砾石充填参数的优化设计和砾石充填方式的优选是完井的核心。
QHD 32 - 6 and SZ 36 - 1 are all low pressure and viscous oil fields with unconsolidated sands, high porosity and high permeability, where sand production is common problem through out of the field development and production. Therefore, sand control is key in development and reservoir protection. It is suggested that a completion method of using inside casing gravel pack is to be used. The optimization of perforation parameters and gravel packing parameters as well as the selection of gravel packing method are the key points during well completion engineering.
