Abstract

The invention provides a furan resin material based on multi-arm cross-linking agent and starch nanocrystal modification as well as a preparation method and application of the furan resin material. The furan resin material is prepared from the following raw materials in parts by weight: 20-40 parts of furan resin and 20-40 parts of filler, 70-95 parts of furan resin, 5-20 parts of a curing agent,0-5 parts of a multi-arm cross-linking agent and 0-5 parts of starch nanocrystals. The furan resin has the characteristics of controllable curing plugging time and long-term stability in acid and alkali resistance and can be used as a matrix of a high-strength permanent plugging material; meanwhile, the mechanical properties and heat resistance of the furan resin material are enhanced by using themulti-arm crosslinking agent and starch nanocrystals. The modified furan resin type plugging material can improve the waterflooding development effect and realize the function of permanently pluggingan underground water outlet layer.

Description

technical field

[0001] The invention relates to the fields of functional polymer materials and oil field fracturing, in particular to a furan resin material modified based on a multi-arm crosslinking agent and starch nanocrystals, and a preparation method and application thereof. Background technique

[0002] Water injection fracturing is a technology that creates cracks in the oil layer through hydraulic action, improves the flow environment of oil in the ground, and thus increases the production of oil wells. However, it also causes problems such as rising water content in the oil field and low utilization of water injection, which affects oil recovery and pollutes at the same time. environment. In order to improve this problem, plugging materials are widely used in the field of fracturing in oilfields.

[0003] Thermosetting resin plugging materials are generally added with curing agents, catalysts, accelerators, toughening agents and other additives, and undergo a curin...
