Abstract
A well mouth capture device used for plunger gas-lift is applied to gas-lift oil extraction in oil fields and water discharge and gas extraction in gas fields. The device is characterized in that the device mainly includes three parts as follows: a buffer, an oil passing tee joint and a capturer. The oil passing tee joint takes the shape of a cylinder and has a center hole; screw threads are formed at the upper end of the oil passing tee joint, and outer screw threads are formed at the lower end; and an oil outlet is fixed on the side wall of the oil passing tee joint. Screw threads are formed at the lower end of the buffer; and the lower end of the buffer is connected with the upper end of the oil passing tee. The capturer adopts a steel ball type capturer which is fixed on the outer wall of the oil passing tee joint. The effect is that the buffer can generate downward buffering power for decreasing the rising speed of a plunger and further protecting the well mouth. When the plunger is required to be repaired, a handwheel arranged on a side surface of the capturer is rotated, so that the plunger can be clamped in the oil passing tee joint by the capturer. An end cover at the top part of the buffer is unscrewed, the handwheel is released, and the plunger can be taken out. In addition, the device has a simple structure, and is applicable to gas-lift oil extraction in oil fields and water discharge and gas extraction in gas fields.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly oil well plunger lift oil recovery, gas well water pumping gas production are a kind of well head special tools that the oil well plunger lift recovers the oil that is used for, and are a kind of plunger trap settings of plunger lift well head.
