摘要:

在陆梁油田生产系统中,生产井筒、抽油杆、集输管线、分离器、加热炉、注水管线等部位都存在不同程度的结垢现象,严重影响了油田的正常生产和安全。水质分析表明陆梁油田的采出水、注入水和地表水均为高矿化度水,有氯化钙和重碳酸氢钠两种水型,水质极不稳定,具有成垢的离子条件。垢物成份分析表明主要以碳酸钙垢为主。说明陆梁油田不同层位的采出水、注入水互不相容,在一定的温度和压力等条件下,一经混合则发生结垢。提出了相应的防垢对策,对保证油田的正常生产具有重要意义。

Abstract: In drilling operation, bottom hole assembly failures take place frequently, which occurs at the thread connection, where stress concentrates relatively. Study is aimed at box threads of ¢177.8 mm/drill collar to analyze and calculate drill collar box thread with different stressrelief grooves using finite element method, the stress concentration of thread end of 3 types of box threads is gained under same boundary condition and load. The calculation indicates the stressrelief grooves designed by the authors with better effect and best resistance of fatigue, so the grooves are recommended.
