油田的井下作业对于油田的勘探开发具有至关重要的意义,关乎着油田的正常生产,但是在油田的生产过程中,各种井下事故时有发生,典型的就是不出油或者不正常出油,影响正常的生产秩序。在对油井进行大修之前需要搞清楚油井问题的原因,再根据需要采取相应的施工程序和技术,一般井下作业大修采用的施工程序都十分复杂,对技术的要求也非常高,所以需要先进的技术设备和大修专业人员。在科学技术飞速发展的今天,井下作业大修技术也不断进步,笔者对此进行了系统的研究和探讨,旨在为油田井下作业大修施工提供科学的技术支持,保证油田在遇到井下事故后快速的恢复正常生产秩序。
Downhole operations in oilfields are of crucial importance to the exploration and development of the oilfields and are related to the normal production of the oilfields. However, in the production process of oilfields, various downhole accidents occur from time to time, typically without oil or abnormal oil , Affecting the normal production order. Before overhauling the well, it is necessary to clarify the cause of the well problem, and then adopt the corresponding construction procedures and technologies as required. Generally, the construction procedures for overhauling downhole operations are very complicated and require very high technical requirements. Therefore, advanced technologies are required Equipment and Overhaul Professionals. In today’s rapid development of science and technology, downhole operation overhaul technology also continues to progress, the author conducted a systematic study and discussion, aimed at the oilfield overhaul work downhole construction to provide scientific and technical support to ensure that the oil field in the face of underground accidents quickly The restoration of normal production order.
