Abstract

The invention discloses a ground-based simulation testing device of a packer. The ground-based simulation testing device of the packer mainly comprises a supporting frame (1), a suspension device and the packer (2), wherein the suspension device is arranged on the supporting frame (1), and the packer (2) is connected with the suspension device. The packer (2) is arranged in a simulation oil well (3), and the ground-based simulation testing device of the packer further comprises a heating pool (4) connected with the interior of the simulation oil well (3). By simulation of the working status of the packer in the well, each main technical parameter of the packer is tested, and using quality of the packer is guaranteed after the packer leaves a factory.

Description

technical field [0001] The invention relates to a ground simulation test device for a packer. Background technique [0002] In crude oil production at home and abroad, mechanical oil recovery occupies the primary position, and in mechanical oil recovery, oil well pumps are the main ones. Oil well pump is one of the most basic, reliable and widely used oil pumping tools. According to statistics, the oil pump accounts for more than 90% of the mechanical oil production wells. The oil pump equipment plays a vital role in the entire crude oil production. The economic loss caused by the failure of the oil pumping device, especially the downhole device is extremely huge. Therefore, timely and accurate monitoring and judgment of the working status of the oil pump, and effective and timely processing of the failures that occur will not only greatly reduce the production cost of crude oil and obtain higher economic benefits, but will also help to further improve the oil field. leve...
