Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the device for solving the blockage, specifically to a low permeability oil reservoir device for solving the blockage. BACKGROUND

[0002] Oil extraction refers to the process of pumping oil from the formation to the ground. From the perspective of objective underground energy, it can be divided into two types: self-flowing oil extraction and artificial lifting. In actual production, oil wells with good reservoir properties and high pressure can self-flow to the ground, which is self-flowing oil extraction. For oil wells with poor reservoir properties and low pressure, artificial energy supplement is needed when the formation energy is insufficient to lift oil and gas to the surface. Machines are required for extraction. Blockage may occur during machine extraction, which requires the use of a device for solving the blockage.
