套管是油井的躯干,井下套管的好坏直接影响油田开发。为了延长油井寿命,人们总是想尽一切办法保护井下套管。譬如,采用阴极保护和防腐缓蚀剂防止套管腐蚀,常采用时间推移办法对套管进行电磁测井、声波电视测井、垂直测井、多臂井径测井等一系列的检测工作,及时了解套管腐蚀、变形、破裂等损伤程度。另外,当发现套管损坏,还要采用修补措施加以挽救。总之,油井开发的实践证明,对油井套管的保护是至关重要的。为此,就射孔对套管的损害及改进措施谈点看法。 Casing is the trunk of the well. The casing in the well directly affects the development of the oilfield. In order to extend the life of the well, people always try their best to protect the casing. For example, cathodic protection and anticorrosive corrosion inhibitors are used to prevent corrosion of the casing, and a series of testing work such as electromagnetic logging, acoustic TV logging, vertical logging, Timely understanding of casing corrosion, deformation, rupture and other damage. In addition, when the casing is found damaged, but also to remedial measures to be saved. In a word, the practice of oil well development proves that the protection of well casing is of utmost importance. To this end, on the perforation of casing damage and improvement measures to talk about point.
