摘要
剖析典型案例井DPT-75井套管挤毁事故的全过程,指出最易诱发事故的诸多因素,提出合理化的建议。在此基础上,制定了科学的气田试压流程规范,实现了试压的节点控制,现场再未发生此类事故。
By analyzing typical cases about DPT-75 casing collapse accidents,the most likely cause of accidents is found out and the rational suggestions are put forward. On this basis,the scientific testing process specification is made to implement the node control of pressure testing. Therefore,there is no such accidents in Daniudi gas field any more.
