压裂用树脂涂覆类可固化支撑剂人工岩心模具的研制及使用方法

Development and Application of Artificial Core Mold for Compressive Strength Test of Resin Coated Curable Proppant Used for Fracturing

抗压强度是压裂用树脂涂覆类可固化支撑剂检测的一项重要指标,该指标直接影响压裂施工效果。为制作出适用于压裂用树脂涂覆类可固化支撑剂抗压强度实验的人工岩心,依据抗压强度标准中对人工岩心制作要求,参考多种制作人工岩心的模具,研发了高温高压人工岩心制作模具。依据标准设计外观形状尺寸,无需二次磨制加工。应用此模具与方法制备出的人工岩心所得到的抗压强度实验数据相对误差较小,平行性较好。为研究国内外压裂用树脂涂覆类可固化支撑剂所用人工岩心与产品选择提供技术支持,并填补了国内制作方法空白,为今后油田开发用人工岩心制作提供参考依据。

Compressive strength is an important index for testing resin coated curable proppants for fracturing,which directly affects the effect of fracturing operation.In order to make artificial cores suitable for compressive strength test of resin-coated curable proppants used in fracturing,according to the requirements of artificial cores in compressive strength standards,and referring to a variety of molds for making artificial cores,a high temperature and high pressure artificial core mold was developed.The shape and size of the core are designed according to the standard without grinding.The experimental data of compressive strength obtained from the artificial cores made by this mold and method have smaller relative error and better parallelism,which provides technical support for the selection of resin-coated curable proppant artificial cores and products for fracturing at home and abroad,and provides a reference for the making of artificial cores for oil field development in the future.
