The utility model discloses a novel well-washing pumping pump, which comprises an upper coupling, a pump barrel, a swimming valve assembly, a plunger, a fixed valve assembly, a lower joint and an outer barrel, an outer thread connecting the outer barrel under the upper coupling, an inner thread connecting the pump barrel under the upper coupling of the pump barrel, a pump barrel sleeved outside the plunger assembly, a fixed valve assembly connecting the lower part of the pump barrel through the outer thread, and a well-washing assembly on the pump barrel. The well washing hole is vertically arranged on the wall of the pump barrel. The well washing hole is arranged above the pump barrel. A pull rod is connected above the swimming valve assembly. When the pull rod is lowered, the swimming valve assembly is located below the well washing hole. When the pull rod is pulled up, the swimming valve assembly is located above the well washing hole. The structure design of the utility model is reasonable, and the wax, sand and other impurities in the inner wall of the tubing, the sucker rod and the pump can be cleaned by changing the external washing to the internal washing with only a small amount of water, which not only saves a lot of water for well washing, but also reduces the pollution of the reservoir, shortens the drainage time and saves the production cost.
【技术实现步骤摘要】
一种新型洗井抽油泵
本技术涉及一种抽油泵,尤其是涉及一种新型洗井抽油泵。
技术介绍
在地藏油层中,一般都含有砂、气、蜡或胶脂等。机械采油井中,当含砂或含蜡较严重时经常产生硬卡或软卡等事故并可能造成设备等的损坏,而现有的泵不能将砂子送回泵下。另外,因油流含气,使泵的有效行程缩短,降低了泵效甚至产生气锁,给石油生产带来较大影响。在油井生产过程中,油井的产出液中含有较多的蜡质和胶质的物质,该蜡质或胶质的物质会附着在抽油泵的腔体内壁、抽油泵上的阀球和阀座表面、油管内壁和抽油杆外壁上,影响油井的生产,所以要经常对油井内的抽油泵的腔体、抽油泵上的阀球和阀座表面、油管和抽油杆进行清洗。现有技术中,空心抽油杆位于油管内,空心杆与抽油杆之间形成环形空间,油管位于套管内,油管与套管之间形成环形空间,在空心抽油杆和油管的下端连接有抽油泵,抽油泵包括泵筒、柱塞和泵体,泵筒和油管相连接,空心抽油杆连接实心抽油杆,实心抽油杆连接柱塞,进油阀和出油阀位于泵体内,空心抽油杆的底部设置有排液孔,空心抽油杆通过该排液孔将空心杆和抽油杆之间环形空间相连通。在清洗的过程中,施工人员可以控制油井外的洗井车 ...
