固体火箭推进剂洗井器设计

DESIGN OF WELL-WASHER WITH SOLID ROCKET PROPELLANT

本文根据固体火箭推进剂释放能量高、燃气量大的特点 ,设计出一种新型、高效、快速水井洗井器 ,并从洗井原理、洗井效率、固体火箭推进剂性能等方面对其可行性进行了详细分析和经济评估。采用该洗井器可减少洗井设备、简化现场操作、减少辅助工作量、缩短施工时间 ,提高洗井综合效益。该洗井器在煤田、油田钻井工艺方面也有一定的使用价值。

A new device with solid rocket propellant designed for ground water well washing is introduced in this paper.The design theories including its well washing actions and the energy characters of the propellants are discussed in detail.An economic assessments offered in this paper show that using this device would get higher comprehensive benefits.The design can be applied to oil well and coal well as well.
