Description

Technical Field

[0001] This utility model relates to the field of fracturing fluid-based fluid technology, specifically to a fracturing fluid-based fluid sampler. Background Technology

[0002] Fracturing fluid base fluids refer to the various basic fluids used in fracturing operations. They are typically classified into different types based on their chemical composition and properties. Common fracturing fluid base fluids include water-based fracturing fluids, oil-based fracturing fluids, and foam fracturing fluids. The main components of fracturing fluids include the following key additives: thickeners: such as locust bean powder and guar gum powder, used to increase the viscosity and stability of the fracturing fluid; crosslinking agents: such as borax and organoboron complexes, used to form a stable gel structure; gel breaker: such as enzymes and oxidants, used to degrade the fracturing fluid after fracturing operations, facilitating flowback; emulsifiers: used in oil-based fracturing fluids to stabilize the oil-water mixture. After the fracturing fluid base fluid is prepared, it needs to be sampled and analyzed from the tank. Currently, the fracturing fluid samplers used in the market have relatively simple structures, making it inconvenient to sample fracturing fluid at different depths, resulting in inconvenience. Therefore, a fracturing fluid base fluid sampler is proposed. Utility Model Content
