摘要
油气田开发需要钻井,同时对无效或无经济价值的开采井、层段也需要封堵。为了实现低成本、高效率和高可靠性的油气井封层,开发了一种配合电缆桥塞作业用撞击式注灰装置,在江汉油田累计使用1200余口井,一次性注灰成功率98%以上,装置及应用方法供同行参考借鉴。
The development of oil and gas fields needs drilling. Meanwhile, it also needs to be blocked for the mining wells and sections with no effective or no economic value. In order to realize the sealing layer of oil and gas wells with low cost, high efficiency and high reliability, we have developed impact type ash injection device for cable bridge plug operation. This device has used more than 1200 wells in Jianghan Oilfield, and the success rate of one time injection is over 98%. The device and application methods for colleagues reference.
