Technical Field
[0001] The utility model relates to the technical field of fluid loss agent processing, in particular to a high temperature resistant and anti-collapse fluid loss agent mixing device. Background Art
[0002] During cementing construction, when cement slurry flows through permeable formations under pressure, percolation will occur, causing the cement slurry liquid phase to leak into the formation. This process is generally called water loss. If water loss is not controlled, the reduction in liquid phase volume will increase the density of cement slurry, and the thickening time and rheology will deviate from the original design requirements. A large amount of liquid will flow into the formation, making the cement slurry difficult to pump or even impossible to pump, and causing varying degrees of damage to the formation. In severe cases, the cementing operation may fail. Therefore, high temperature and anti-collapse water loss agents are usually added to the cement slurry to control the loss of the liquid phase in the cement slurry to the permeable formation, thereby maintaining the cement slurry with an appropriate water-cement ratio.
[0003] In the synthesis process of high temperature resistant anti-collapse fluid loss agent, the fluid loss agent is added to the production device after the ingredients are proportioned, and is fully stirred and reacted under certain temperature conditions. During the use of the existing mixing device, the temperature of the heating medium is poorly controlled and the temperature difference is large, which easily affects the mixing effect, and the pipeline is easily blocked when discharging, which is not conducive to collection and use. To this end, the utility model proposes a high temperature resistant anti-collapse fluid loss agent mixing device. Utility Model Content
