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 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). The invention further discloses an up-and-down differential pressure testing method based on the simulation testing device. By simulation of the working status of the packer in the well, up-and-down differential pressure is test, 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 and an upper and lower pressure difference test method. Background technique [0002] In crude oil production at home and abroad, mechanical oil extraction occupies the primary position, and in mechanical oil extraction, oil pumps are the mainstay. The oil well pump is the most basic, most reliable, and most widely used oil well. According to statistics, oil pumps account for more than 90% of mechanical oil production wells. 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 condition of the oil well pump, and effective and timely treatment of the faults that occur, will not only greatly reduce the production cost of crude oil, obtain higher economic benefits, but also help to fu...
