Abstract
Description
Technical Field
[0001] The utility model relates to the field of velvet cyst plugging agent mixing, in particular to a velvet cyst plugging agent mixing device. Background Art
[0002] Velvet plugging agent is a special chemical material used for water plugging, gas plugging, and leak plugging in oil and gas wells. It is usually a mixture of multiple chemical substances such as polymers, cross-linking agents, initiators, stabilizers, etc. It can form a gel or foam with certain strength and toughness in the wellbore, thereby plugging the wellbore or formation. The mixing of velvet plugging agent refers to mixing various chemical raw materials evenly according to a certain proportion and process on the ground or at the wellhead to form a plugging agent system that can be injected into the well. During the mixing process, the proportions and mixing conditions of various raw materials need to be strictly controlled to ensure the stable performance and sealing of the plugging agent. In order to improve the plugging effect, the mixed plugging agent usually needs to be left standing for a certain period of time to allow its chemical reaction to fully complete and form a stable gel or foam structure before it can be injected into the well for plugging operations. The mixing technology of the fleece sac plugging agent is a key link in the application of the plugging agent, which directly affects the performance and plugging effect of the plugging agent. At present, when the fleece sac plugging agent mixing device is used, the mixing work is only carried out by simple stirring during the mixing process, resulting in a relatively long mixing time and a relatively poor mixing effect. It is impossible to add mixing gas to the inside of the mixing cylinder. Therefore, a fleece sac plugging agent mixing device is proposed. Utility Model Content
