Besides the gas with a single strand of gas, the wellhead basically has no liquid production, and the oil sleeve is co
nnected when circulating.减少管柱脱落的措施有:将油管上扣扭矩由原来的值提高到值;采用油管螺纹垫片;定子上的装卸短节采用防松螺纹连接;采用油管锚或张力封隔器固定螺杆泵。The measures to reduce the falling off of the pipe string are as follows: increase the torque from the original value to the maximum value; use the oil pipe screw gasket; the loading and unloading joint on the stator is co
nnected by loosening screw thread; and use the oil pipe anchor or tension packer to fix the screw pump.
B、转子B, rotors转子的结构也非常简单,主体是钢制杆件,一般外涂耐磨耐蚀的铬合金材料。其作用是传递动力和写定子形成密封腔。The structure of the rotor is also very simple, the main body is steel rod, generally coated with abrasion resistant and corrosion resistant chromium alloy material. Its function is to transfer power and write the stator to form a seal cavity.C、回转筒C, rotary barrel回转筒也就是一根内径较大的油管或空心定子筒,接在定子的上部以给转子和抽油杆杆柱以较大的回旋空间,防止转子和抽油杆因偏心运动磨擦磨损油管。A rotary cylinder is also an oil tube or hollow stator barrel with larger inner diameter. It is co
nnected to the upper part of the stator to provide larger swirl space for the rotor and sucker rod string, so as to prevent the rotor and sucker rod from attrition wear due to eccentric wear.
E、抽油杆扶正器E, sucker rod centralizer抽油杆扶正器由心轴和扶正筒组成,它接在两根抽油杆之间,被卡在两个抽油杆接箍之间。心轴也就是一要极短的抽油杆短节。扶正筒是一个内孔比心轴大1MM左右的空心塑料筒,外部有四个略比油管内径小的扶正翼,采取浇注成型。扶正筒可以围绕心轴转动,防止抽油杆旋转时与内壁接触而磨蚀油管,又可以让流体通过。The sucker rod centralizer is comed of the heart shaft and the upright cylinder, which is co
nnected between the two sucker rods and is stuck between the two sucker rod hoops. The axis of the heart is also an extremely short rod short section. The centering cylinder is a hollow plastic tube inner hole Bixin shaft around 1MM, external four slightly smaller than the diameter of the tubing centralizer wing, adopt casting. The centralizer can revolve around the axis to prevent the sucker rod from touching the inner wall when it rotates, and it can also let the fluid pass through.
