16型游梁式抽油机在生产过程中随着油层、井筒情况及油井工作制度的改变会破坏抽油机原有平衡。其平衡状况的好坏会直接造成减速器扭矩突变、电机失载、设备寿命降低以及抽油机运转的平稳性,若长时间失衡运行,易造成平衡块锁紧螺栓松动,造成平衡块坠落。特别是在稠油开采过程中,由于稀油掺稀量不稳定,造成抽油机载荷变化浮动较大,特别是泵挂较深的油井,抽油机上、下冲程电流、载荷变化较为明显,抽油机抖动时常发生,在长时间的运行中,往往会造成平衡块固定螺丝松动,严重时损坏锁块牙齿或曲柄牙齿,若发现不及时易造成抽油机平衡块在离心力的作用下飞出,造成设备损坏,严重时造成抽油机左右连杆受力不均、折断,造成抽油机侧翻、设备报废并伤及井口及管线,造成井喷等安全事故。
16 type beam pumping unit in the production process with the reservoir, wellbore conditions and changes in the working well of the well will destroy the original balance pumping unit. The balance of the situation will result in a direct result of the reducer torque mutation, the motor is lost, the equipment life expectancy and smooth operation of the pumping unit, if a long period of unbalanced operation, easy to cause the balance block locking bolts loose, causing the balance block to fall. Especially in the process of heavy oil production, due to the instability of dilute oil doping, the fluctuation of pumping unit load fluctuates greatly. Especially for the wells with deep pumping, the load and up-down stroke of pumping unit are obvious, Pumping often occurs in the long run, often cause the balance block loose screws loose, serious damage to the lock block teeth or crank teeth, if not found in time is easy to cause the pumping block balancing block under the action of centrifugal force Out, resulting in equipment damage, resulting in severe pumping rod around the uneven force, broken, resulting in pumping unit rollover, scrapped equipment and hurt wellhead and pipeline, resulting in blowout and other safety incidents.
