Description

Technical Field

[0001] The utility model relates to the field of thickener polymer emulsion systems, in particular to a thickener polymer emulsion system for fracturing. Background Art

[0002] The commonly used natural plant gum fracturing fluids such as guar gum and cellulose have high insoluble content and additional damage caused by cross-linking, which block the fracturing reservoir and proppant filling layer, causing a significant decrease in the conductivity of the fractures, and fail to achieve the expected effect of fracturing and production increase, or even have a negative effect. In addition, the temperature and shear resistance of this type of fracturing fluid (especially the shear resistance of the gel) is not ideal, and it is difficult to be used for fracturing in high-temperature deep formations. Therefore, synthetic water-soluble polymer fracturing fluids have become a hot topic of research at home and abroad. Compared with natural plant gums, they have the advantages of strong thickening ability, insensitivity to bacteria, good gel stability, strong sand suspension ability, no residue, and little damage to the formation.

[0003] Acrylamide multipolymer is a typical and most widely studied water-soluble polymer. Its application performance as a fracturing fluid thickener has gradually matured. However, in certain specific situations, such as when the construction equipment is simple and the construction process is simplified, the use of this type of fracturing fluid has some disadvantages or limitations: First, since the dry powder thickener dissolves slowly when preparing the solution, even the instant thickener needs a certain dissolution time; second, when preparing on-site, the dry powder thickener has strong water absorption, and poor preparation conditions can easily cause the fracturing fluid to form powder particles or fish eyes, affecting the performance of the fracturing fluid; finally, even if some dry powder thickeners can meet the continuous mixing construction conditions, under extreme conditions, such as when there is no mixing vehicle but only a sand mixing vehicle, and only the "online construction" mode can be adopted, this type of fracturing fluid system cannot complete the construction at all. Microemulsion polymerization, a new technology for the polymerization of water-soluble monomers developed in the past decade, is a transparent or translucent, thermodynamically stable oil-water dual-continuous phase system formed by water, oil, surfactants and co-surfactants. This microemulsion polymer has a high molecular weight, can be used directly, can be quickly dispersed and dissolved in water, and is designed into a new type of fracturing fluid system through other auxiliary functions.

[0004] The on-site mixing method of the weak gel fracturing fluid of the fracturing fluid system is as follows: first, clean the continuous mixing tank, prepare the mixing water, instant emulsion thickener, functional additives, clay stabilizer, weak cross-linking agent and gel breaker, and connect the continuous mixing equipment pipeline and fracturing construction equipment; then, suck the mixing water into the mixing tank, add the clay stabilizer, functional additives and instant emulsion thickener at the inlet of the continuous mixing circulation tank, swell, mix evenly and then pump into the sand mixing truck, etc. When mixing inside the mixing tank, liquid water and other reagents need to be prepared in advance and then poured into the mixing tank in sequence. The operation steps are relatively cumbersome, the preparation steps are slow, and the mixing work efficiency is reduced.

[0005] Therefore, it is necessary to provide a polymer emulsion system for fracturing thickener to solve the above technical problems. Utility Model Content
