塔河油田注氮气采油是碳酸盐岩油藏重要的提高采收率措施之一,取得了较好的降递减和增油效果。但目前采用的膜分离制氮和碳分子筛分离制氮技术,制氮纯度分别为97%和99%,注入气中含一定量的氧气。随着注气轮次的增加,井筒腐蚀日趋严重。... 详细信息

塔河油田注氮气采油是碳酸盐岩油藏重要的提高采收率措施之一,取得了较好的降递减和增油效果。但目前采用的膜分离制氮和碳分子筛分离制氮技术,制氮纯度分别为97%和99%,注入气中含一定量的氧气。随着注气轮次的增加,井筒腐蚀日趋严重。针对注氮气井井筒腐蚀问题,采用高温高压动态腐蚀模拟装置,开展注氮气井井筒腐蚀机理研究,测定注气氧含量、温度、注气压力和注入速度对腐蚀速率的影响。实验表明,温度从70℃升至110℃,模拟井下环境管材腐蚀速率增大1.3~2.0倍,达到4.23 mm/a;注气氧含量从0.7%提高至1.5%,模拟井下环境管材腐蚀速率增大0.7~1.0倍,达到2.91 mm/a。分析井筒腐蚀的主控因素为注气氧含量和温度。进行注氮气采油井筒腐蚀对策讨论,提出了提高制氮纯度减少氧含量,配套内衬管和缓蚀剂的思路,可有效治理注氮气采油井筒腐蚀。

Current treatments for epilepsy can only manage the symptoms of the condition but cannot alter the initial onset or halt the progression of the disease. Consequently, it is crucial to identify drugs that can target novel cellular and molecular mechanisms and mechanisms of action. Increasing evidence suggests that axon guidance molecules play a role in the structural and functional modifications of neural networks and that the dysregulation of these molecules is associated with epilepsy susceptibility. In this review, we discuss the essential role of axon guidance molecules in neuronal activity in patients with epilepsy as well as the impact of these molecules on synaptic plasticity and brain tissue remodeling. Furthermore, we examine the relationship between axon guidance molecules and neuroinflammation, as well as the structural changes in specific brain regions that contribute to the development of epilepsy. Ample evidence indicates that axon guidance molecules, including semaphorins and ephrins, play a fundamental role in guiding axon growth and the establishment of synaptic connections. Deviations in their expression or function can disrupt neuronal connections, ultimately leading to epileptic seizures. The remodeling of neural networks is a significant characteristic of epilepsy, with axon guidance molecules playing a role in the dynamic reorganization of neural circuits. This, in turn, affects synapse formation and elimination. Dysregulation of these molecules can upset the delicate balance between excitation and inhibition within a neural network, thereby increasing the risk of overexcitation and the development of epilepsy. Inflammatory signals can regulate the expression and function of axon guidance molecules, thus influencing axonal growth, axon orientation, and synaptic plasticity. The dysregulation of neuroinflammation can intensify neuronal dysfunction and contribute to the occurrence of epilepsy. This review delves into the mechanisms associated with
