注水开发油田,油水井套管损坏是一种极为普遍的现象,但又各具特点。本文通过从平面、剖面、时间上总结呼和诺仁油田贝301区块套管损坏井的规律,并结合贝301区块实际,提出贝301区块地质构造特点,加密井调整时期的钻孔关井影响以及措施施工等套管损害机理。依据套管损坏原因,本着治理与预防相结合的方针,以预防断层复活,加强压力监测和油水井方案及时跟踪调整,控制注水压力等方面减少和控制套管损坏。最后,简单叙述对油田套管损坏的认识。
Water injection development of oil fields, oil wells casing damage is a very common phenomenon, but also have their own characteristics. In this paper, we summarized the regularity of casing damage in Bei 301 block in Huhe Noren Oil Field from the aspects of plane, section and time, and combined with the characteristics of Bei 301 block, proposed the geological structure features of Bay301 block, The impact of well closure and casing construction damage measures. According to the cause of casing damage, in line with the combination of treatment and prevention guidelines, to prevent the resurgence of the fault, to strengthen the pressure monitoring and oil and gas wells program to track and adjust timely control of water pressure to reduce and control casing damage. Finally, a brief description of the casing damage awareness.
