Description

TECHNICAL FIELD

[0001] The utility model relates to oilfield downhole operation technical field especially relates to a thin oil area oil pipe reciprocating conveying device. BACKGROUND

[0002] The patent of a name oil pipe trolley is disclosed in the application No. 2014207202315. The trolley needs two people to operate to complete the tripping operation, needs double manpower, and the pulley is driven by a spring and only exists in the ideal state of stable site, four pulley load uniform friction force is very big, if the well site ground cannot reach the complete level, the oil pipe bridge will also have some angle, the oil pipe has crude oil in the downhole operation, which is unavoidable, so as long as there is a certain inclination angle and crude oil skidding, the pulley will produce idling, the trolley will not return to the original position, and the control problem of the trolley cannot be completely solved. The original trolley does not reinforce the bottom plate, and the problems of punching the bottom plate and expanding the bottom edge will occur for a long time. The spring of the original pulley has a service life, and the service life of the spring bow piece is usually 5000 to 10000 times. According to the working intensity of the downhole operation, at least 500 times of use can be achieved every day, which means that in the ideal state without idling, the minimum ten days need to replace 4 spring bow pieces. Frequent replacement of accessories means the increase of material cost, labor cost and time cost. The original trolley cannot realize the oil pipe conveying problem in the single person oil pipe process.

[0003] In oil exploitation, the oil pipe is connected by a thread and a coupling. In the tripping operation of well repair operation, the male thread is exposed and is easy to collide and wear with the slide, resulting in that the oil pipe connection is not tight or cannot be connected, and the small trolley plays a role in protecting the male thread of the oil pipe.

[0004] The trolley currently used needs two people to cooperate to use the trolley to transport the oil pipe in the operation, and the rear staff often needs to touch the trolley with hands, which can cause the hand squeezing accident. The front slide clamp has no shielding oil pipe, and the oil pipe can fall off the slide and injure the wellhead personnel. In the case that the well site condition does not allow, the staff standing under the horse head of the production oil pumping unit will be a great safety hazard. The trolley cannot be pushed to the specified position due to insufficient force or oil pollution of the slide, causing unnecessary stagnation and affecting the work efficiency. The impact force is converted from point force to surface force through the reinforcement of the floor, and the bottom edge reinforcing rib strengthens the bottom of the trolley, greatly improves the service life of the trolley, and avoids the economic loss caused by the stop.
