Long stroke fracturing pump turbulator with dropping and connecting device

Abstract

The invention relates to a long stroke fracturing pump turbulator with a dropping and connecting device, the long stroke fracturing pump turbulator with the dropping and connecting device can play a turbulent flow role on fracturing fluid in a long stroke pump cylinder and reduce solid particles deposition in the pump cylinder. According to the technical scheme, the cylindrical helical spring with a rectangular section is arranged in the pump cylinder, one end of the spring is connected with a valve box through a bolt, the other end of the spring is provided with a plug, and the other end of the spring is connected with the plug through a bolt; a socket is fixed to one end portion of a plunger though a bolt; the plug comprises a conical head and a base, the conical head is welded on the base, and the base is fixed to one end portion of the spring through a bolt; the plug comprises guiding awls, a fixing jaw and a base, the shape of the fixing jaw matches with the shape of the conical head, and the fixing jaw is welded on the base; the guiding awls are in a fan shape, the guiding awls are welded to one end portion of the fixing jaw, and at least four guiding awls together define a taper face. The long stroke fracturing pump tabulator with the dropping and connecting device is simple in structure and strong in feasibility.

Description

technical field [0001] The invention relates to a spoiler for a long-stroke fracturing pump. Background technique [0002] In well completion operations, multi-stage fracturing of horizontal wells has become the main construction mode at present and in the future. In 2013, the total number of fracturing operations in China was about 40,000 well layers, and the construction operations in large and ultra-deep layers increased at a rate of 15% every year. A large number of oil and gas regions in my country are concentrated in hills and mountainous areas, and the construction roads, well site area and water supply are relatively limited. Vehicle-mounted fracturing equipment has become a necessary condition, and high-power equipment has become a preferred condition. Patent CN201310700277.0 discloses a high-power hydraulically driven fracturing pump system, which effectively reduces the number of fracturing crews, facilitates the arrangement of the crews at the well site and saves...

Problems solved by technology

However, due to the low stroke frequency, the fracturing fluid stays in the long-stroke pump cylinder for a long time and flows smoothly. The solid particles in the fracturing fluid are easy to settle and accumulate at the inlet of the pump cylinder.
