Abstract

The invention provides a cohesion-type foam drainage blender. The cohesion-type foam drainage blender comprises a base with a support, rotation blades, and a blender main body with bearings fitting to a middle base. The top of the outer part of the base is provided with a chamfer matching with a tubing nipple. The base is provided with three support frames for fixing the support and is provided with a gas-liquid channel. One end of the support of the base is provided with three locking raised parts for adjusting the blender main body to a correct position. The blender main body is characterized in that the middle base between the bearings at two ends is positioned to and matches with the bearings by three cylindrical pins. The external diameter of the middle base is slightly smaller than those of the bearings. Two ends of the blender main body are positioned by fixing gaskets. The cohesion-type foam drainage blender does not influence the gas-liquid channel. Stratum gas drives the blender to rotate so that gas and liquid are concentrated to the middle part of a shaft, olisthy is reduced, a foaming amount is increased and foam drainage efficiency is improved.

Description

technical field [0001] The invention belongs to a foam drainage gas collection device, in particular to a cohesive foam drainage agitator. Background technique [0002] For a long time, as one of the traditional drainage gas recovery techniques, foam drainage gas recovery has lacked innovation, that is, foam drainage agent is injected from the tubing (or casing) of liquid-loaded gas well, so that the foam drainage agent generates foam to carry liquid, and the formation produces The liquid is brought out of the wellbore under the power of gas. Although there are various ways to inject the foaming agent, they all stop when the foaming agent contacts the liquid. Due to complex downhole conditions, differences in physical properties between the foaming agent and downhole liquid, and unstable gas production, the contact surface between the foaming agent and the liquid is too narrow, too little foam is produced, and the liquid carrying capacity is insufficient, especially when the...
