【摘要】：水平井是开发油气田的一种有效手段,在水平井检修的过程中常常要遇到压井过程,为了能更好的发挥水平井高产的效果,因此在水平井压井过程中,对压井液的要求较高,辽河油田在水平井小修作业施工针对特殊的压井液压井的复杂问题、处理特殊工况有所欠缺,阻碍了水平井小修作业的进行,因此针对在水平井小修作业遇到的压井液问题开展研究。本课题主要是通过对欢喜岭油田联合站污水进行处理或者增加添加剂,以污水为原液配制压井液,减小污水对地层的伤害。通过对欢喜岭油田联合站污水的分析,包括化学成分对地层的伤害分析,污水悬浮颗粒分析对地层的伤害分析,以实验为基础,监测各组分对地层的损害程度,针对损害成分的伤害机理添加合适的添加剂,到达减少伤害的目的。通过研究得出欢喜岭油田污水中不溶性颗粒对地层伤害结论,针对污水进入地层会对地层造成伤害的问题,减小污水颗粒对地层的伤害,减小了污水的滤失量。
[Abstract]:Horizontal well is an effective way to develop oil and gas field. In order to give full play to the high production effect of horizontal well, it is often encountered in the process of horizontal well maintenance. Liaohe oil field in horizontal wells minor repair operation in view of the complex problems of special hydraulic wells, the treatment of special conditions is deficient, hindering the horizontal wells minor repair operation. Therefore, the problem of drilling fluid in horizontal well minor repair operation is studied. This subject is mainly through the treatment of waste water of Huanxiling oilfield combined station or the addition of additives, with sewage as the original solution to prepare the well killing fluid. Through the analysis of waste water in Huanxiling oilfield combination station, including the chemical composition of the formation damage analysis, sewage suspended particle analysis to the formation damage analysis, based on the experiment. Monitoring the damage degree of each component to the formation and adding appropriate additives to the damage mechanism of the damage components. Through the research, the insoluble particles in the sewage of Huanxiling Oilfield will harm the formation, aiming at the problem that the sewage into the formation will cause damage to the formation, and reduce the damage of the sewage particles to the formation. The filtration amount of sewage is reduced.
