可调整中心的采油树井口装置制造方法及图纸

可调整中心的采油树井口装置，应用于油田采油井口。在井口闸锥座式油管头上端法兰的上有一个可调油管连接器；可调油管连接器由圆环形钢板和油管短节组成，可调油管连接器的圆环形钢板下平面与井口闸锥座式油管头的法兰上平面接触；在可调油管连接器的圆环形钢板上平面有一个圆环形连接法兰。连接法兰的下平面有环形凹槽，在环形凹槽内有法兰上密封钢圈。效果是：可调油管连接器能在井口闸锥座式油管头锥形中心孔内移动，调整可调油管连接器中心与抽油杆相对。解决由于抽油杆、抽油管不对中造成的偏磨，减少油井作业次数，提高开井时率，降低生产运行成本。（*该技术在2021年保护过期，可自由使用*）

Oil well wellhead device capable of adjusting center

The oil well wellhead device with adjustable center is applied to oil well wellhead. At the wellhead gate cone seat type tubing head top flange has an adjustable tubing connector; adjustable tubing connector is composed of circular plate and circular steel tubing joint, adjustable tubing connector contact flange plane and wellhead gate cone seat type tubing head on the plane; the circular plate adjustable tubing the connector on the plane of a circular flange. The lower plane of the connecting flange is provided with an annular groove, and a steel ring is sealed on the flange in the annular groove. The utility model has the advantages that the adjustable oil pipe connector can move in the conical central hole of the wellhead cone type oil pipe head of an oil well head, and the adjustable oil pipe connector center is opposite to the oil pumping rod. The utility model solves the partial abrasion caused by the misalignment of the sucker rod and the oil pipe, reduces the operation times of the oil well, improves the time of opening the well and reduces the operation cost.
