采油循环钻井系统
摘要：
本发明涉及一种钻井系统，特别涉及一种采油循环钻井系统，其技术方案是：主要是由主体连接器、分流器、管线、液压站、控制装置、驱动器、支撑架组成，主体连接器、控制装置固定在支撑架上，主体连接器与控制装置连接，主体连接器的顶部连接驱动器，所述的控制装置连接液压站，液压站通过管线连接分流器；本发明的有益效果是：改变了钻井作业方式，系统可保证在接单根时保持钻井液的连续循环，有效避免接单根引起的压力波动，改善井眼质量和清洁度，降低循环漏失、底层破裂、卡钻等现象发生的几率，提高油井生产效率。
摘要（英）：

The invention relates to a well drilling system, and in particular relates to an oil extraction circulation well drilling system. The technical scheme is as follows; the oil extraction circulation well drilling system mainly consists of a main body connector, a flow divider, a pipeline, a hydraulic station, a controller, a driver and a supporting frame, wherein the main body connector and the controller are fixed on the supporting frame, the main body connector is connected with the controller, the top of the main body connector is connected with the driver, the controller is connected with the hydraulic station, and the hydraulic station is connected with the flow divider through the pipeline. The oil extraction circulation well drilling system has the beneficial effects of changing a well drilling operation manner, being capable of ensuring continuous circulation of well drilling fluid when a single pipe is connected due to the system, effectively preventing pressure fluctuation caused by single pipe connection, improving the quality and the cleanness of a well mouth, reducing the probability of situations such as circulation loss, bottom breakage, tool sticking and the like, and improving the production efficiency of an oil well.
