在活塞洗井过程中,由于打破井管而造成堵埋活塞事故,一般处理采用卡钻硬提硬顶,很少收到预期的效果。我们在某生产井施工中,用活塞洗井时,由于活塞顶端打破井管,填砾砂泥进入井内,将活塞堵埋住,上下不能活动,把抽筒活塞“埋死了”。开始想用空压机抽水清理井内沉积物的方法来清除进入的堵埋物,但结果并未能够 In the piston flushing process, due to break the well tube and cause piston plugging, the general handling of the use of hardcore hard top hard to note, seldom received the desired results. When we use a piston to wash the well in a production well construction, because the top of the piston breaks the well pipe and the gravel sand enters the well, the piston is buried and blocked, and the piston of the cylinder is “buried”. Began to want to use air compressor to clean up the sediment in the well to clear the incoming plug, but the result was not able to
