[0002] Polyacrylamide (PAM) is a linear high molecular polymer. It is a hard glassy solid at room temperature. Its products include glue, latex, white powder, translucent beads and flakes. It has good thermal stability and can be dissolved in water in any proportion. The aqueous solution is a uniform and transparent liquid. After long-term storage, the viscosity of the solution will decrease due to the slow degradation of the polymer, especially when the storage and transportation conditions are poor. Polyacrylamide is widely used as a lubricant, suspending agent, clay stabilizer, oil displacement agent, fluid loss reducer and thickener in drilling, acidizing, fracturing, water plugging, cementing, secondary oil recovery and tertiary oil recovery. It is an extremely important oilfield chemical. When preparing polyacrylamide, the mixing degree of polyacrylamide and water needs to be tested to see whether it meets the standards.

[0032] When the sampler 112 is installed using the utility model, the knob 124 is turned to allow the adjusting rod 125 to adjust the length of the adjusting plate 113, so that the space between the L-shaped plate 114 and the placement plate can accommodate the sampler 112, and then the two clamping plate bodies 122 are pressed to expand the two clamping plate bodies 122 to a size that can accommodate the sampler 112, and the sampler 112 is placed between the two clamping plate bodies 122 and located on the placement seat 116.
