Anti-adhesion crushing device for oil extraction profile controlling and flooding agent and using method thereof

Abstract

The invention discloses an anti-adhesion crushing device for an oil extraction profile controlling and flooding agent. The anti-adhesion crushing device comprises an unpowered vacuum cooling type anti-adhesion device, a rotary pressure control type vacuum control feeding device, a precise grinding and crushing driving device and a self-stirring intermittent crushing and grinding execution device. The invention belongs to the technical field of oil extraction profile controlling and flooding agent crushing, and particularly relates to the anti-adhesion crushing device for the oil extraction profile controlling and flooding agent and a using method thereof. Through the slow feeding rotating movement of a hollow rotary framework, a negative pressure cavity is formed in the back of an arc-shaped high-hardness grinding baffle in the grinding process, and heat generated by a grinding part near the arc-shaped high-hardness grinding baffle is absorbed by utilizing the characteristics that the molecular activity intensity is reduced and the temperature is reduced in a space with relatively small pressure, so that adhesion caused by the too high temperature of the oil extraction profile controlling and flooding agent is prevented; and through the self-stirring intermittent crushing and grinding execution device, under the condition that no special stirring device is used, the effect of automatic stirring and rolling can be achieved only through an ingenious mechanical mechanism.

Description

technical field [0001] The invention belongs to the technical field of oil production control and displacement agent crushing, and specifically refers to an oil production control and displacement agent anti-bonding crushing device and a use method thereof. Background technique [0002] Control and flooding agent is a chemical additive widely used in oilfield tertiary recovery. The original product is in the form of large particles, and its physical properties are similar to hard plastics. When applied, it should be processed into ultrafine powder with a particle size of 300 mesh. The physical properties of the agent are special, and the heat generated during the crushing process can soften it, reduce its brittleness, and even agglomerate. Therefore, the ultrafine crushing of this material is extremely difficult. The material was processed by a white cast iron pulverizer before. Due to the above reasons, the effect is not good, and the processing cost is too high. However, t...

[0002] Control and flooding agent is a chemical additive widely used in oilfield tertiary recovery. The original product is in the form of large particles, and its physical properties are similar to hard plastics. When applied, it should be processed into ultrafine powder with a particle size of 300 mesh. The physical properties of the agent are special, and the heat generated during the crushing process can soften it, reduce its brittleness, and even agglomerate. Therefore, the ultrafine crushing of this material is extremely difficult. The material was processed by a white cast iron pulverizer before. Due to the above reasons, the effect is not good, and the processing cost is too high. However, there is currently no ultra-fine processing equipment for oil production control and flooding agents in China.

[0003] According to the analysis of the causes of sticking and agglomeration, the main reason for the sticking and agglomeration of the oil production control and displacement agent is the high temperature generated during the grinding process. If the heat can be transferred to the outside in time during grinding, this problem can be solved well. However, in order to ensure that the particle size of the grinding powder is small enough, most of the grinding execution parts have a small space and do not use heat dissipation. Therefore, the present invention proposes an oil recovery control and flooding agent anti-bonding crushing device based on vacuum heat dissipation and its use method
