Description

Technical Field

[0001] The utility model relates to the technical field of water plugging and profile control fillers, in particular to a novel water plugging and profile control device. Background Art

[0002] At present, in the middle and late stages of oil field development, the formation energy decreases and the recovery rate decreases. Most of my country's oil fields supplement the formation energy by injecting water to increase the recovery rate. However, since the reservoirs are usually heterogeneous, there will be "invasion" and "channeling" of water in the oil layer. As the amount of water injection increases, the unevenness of the water injection profile increases, resulting in a large amount of water output from the oil wells. At this time, it is necessary to plug the water and adjust the profile.

[0003] Among them, due to the multi-layer heterogeneity of the formation, the distribution of injected water is uneven. Some areas may quickly break through the high permeability layer, resulting in a large amount of water output from the oil wells and reducing production capacity. In order to solve this problem, chemical agents will be injected into the formation to block the water flow channel of the high permeability layer, forcing water to enter the low permeability layer or high oil-containing layer, thereby improving the efficiency of water-driven oil.

[0004] However, when adding plugging agents in the market, the pressure is often insufficient, which makes it difficult for the plugging agents to be evenly distributed inside the formation. Therefore, it is necessary to design a new technical solution to solve this problem, so that the plugging agents can be efficiently and evenly distributed in the formation. Utility Model Content
