The utility model relates to a kind of cleaning disinfection nozzle and a high-pressure water gun, cleaning disinfection nozzle includes nozzle body, nozzle body includes first spout and second spout;First spout is sequentially provided with multiple first tooth shape, and second spout is sequentially provided with multiple second tooth shape;Multiple first tooth shape and multiple second tooth shape are oppositely arranged;Multiple first tooth shape and multiple second tooth shape between gap that allow liquid to pass;Gap is by the one end of nozzle body to the other end of nozzle body wave shape extension;The size of gap between first tooth shape and second tooth shape has multiple specifications.High-pressure water is strongly rubbed with multiple first tooth shape and multiple second tooth shape respectively, and more abundant foam is generated, the foam effect of drug water is enhanced, the cleaning disinfection performance and utilization of drug water are improved;Select corresponding gap specification, can increase the jet area while maintaining good jet force, improve cleaning efficiency, save drug water cost.

The application discloses a collophanite reverse flotation process applied to yield improvement, and the process is characterized in that flotation reagents are sequentially added into phosphorite slurry and then introduced into roughing operation, roughing is carried out, and rough concentrate and foam product I are obtained; the foam product I is introduced into one-stage scavenging after adding an adjusting agent, and scavenging concentrate I and foam product II are obtained; the scavenging concentrate is reselected after adding flotation reagents, and reselected concentrate and foam product III are obtained; the reselected concentrate and the rough concentrate are mixed and then introduced into cleaning after adding flotation reagents, and final concentrate and foam product IV are obtained, and the foam product IV is returned to the roughing operation; the foam product III is mixed with the foam product II, and two-stage scavenging is carried out, and scavenging concentrate II and foam product V are obtained, the foam product V is final tailings, and the scavenging concentrate II is returned to the one-stage scavenging operation. The process is stable, simple and efficient, has strong adaptability to ores, and has low phosphorus content of tailings and higher phosphorus yield.

This invention relates to the field of oilfield development technology, specifically to a high-temperature resistant oil displacement foaming agent, its preparation method, and its application. The method involves first preparing a main agent solution containing a high-temperature resistant additive and a main agent, then adding a foam stabilizer for compounding, and finally maturing to obtain the high-temperature resistant oil displacement foaming agent. The main agent includes alkyl aryl sulfonate derivatives, the high-temperature resistant additive is an acrylamide derivative, a styrene derivative, or an organophosphonate, and the foam stabilizer is modified guar gum. The compounding temperature is 120-150℃, the reaction pressure is 0.3-0.5 MPa, and the time is 4-6 hours. This method achieves synergistic effects among the main foaming agent, modified guar gum, and organophosphonate, forming a stable system. This high-temperature resistant oil displacement foaming agent possesses excellent thermal stability and interfacial activity; it exhibits both excellent high-temperature and salt resistance and efficient foaming, foam stabilizing, and oil displacement effects under ultra-high temperature, ultra-high salinity, and high calcium and magnesium ion environments.

The application discloses a high-salt-resistant foaming agent, which can meet the requirements of drilling construction in complex strata by coping with harsh geological conditions in the process of foam drilling and multiple requirements of foam inhibition and foaming capacity. The foaming agent is composed of the following components in percentage by mass: 12-60wt% main foaming agent, 10-30wt% auxiliary foaming agent, and the balance of water. The main foaming agent is a betaine zwitterionic surfactant containing a polyether chain segment, and the auxiliary foaming agent is an amino propionic acid type zwitterionic surfactant. The foaming agent system prepared by the application has the advantages of temperature resistance of 140 DEG C, salt resistance of 360000mg / L NaCl, excellent foaming effect, good salt resistance and good inhibition effect on hydration of mud shale.
