| 摘 要： | 超稠油藏开发过程中，防止井筒凝管是在开发作业中必须面临的难题，生产或作业过程易发生稠油在井筒内凝固，堵塞井筒，甚至高压不能打通的情况。以往修井处理过程经常出现稠油不易返出、堵塞循环系统、稠油进灌无法正常回收、稀油用量大等问题，施工难以连续，周期长，劳动强度大，费用高。塔河油田在措施作业过程中，结合超深、超稠油的特殊井况，采用分段倒扣配合连续油管切割技术、钻磨处理技术和地面装置改进技术，使稠油凝管处理更加高效、快速。

| Abstract: | In the development of super-heavy oil reservoir, it is very important to prevent coagulation in wellbore. Heavy oil often coagulates and blocks wellbore, and even high pressure fails to go through. In the previous workover treatment, some problems existed, such as the difficult return of heavy oil, the block of circulation system, the abnormal recovery of heavy oil feeding, the dilute oil high consumption, difficult construction, long cycle, high labor intensity and high cost. According to the special well conditions of ultra-deep and super-heavy oil, the buckle with coiled tubing cutting technology, the drilling and grinding technology and the ground device improvement technology have been applied in the Tahe Oilfield, making the prevent of super-heavy oil coagulation more efficient. |
