摘要: 基于调剖堵水产品与食品工业产品如明胶等的相似性,引入食品工业中性能定量评价中常用的质构评价方法,以体膨颗粒为例开展调剖堵水用化学剂质构仪定量强度评价探索。利用CT-3质构仪对4种具有不同膨胀倍数的体膨颗粒开展质构分析,在压缩模式下,获得第一循环硬度和硬度形变量等参数,获得强度顺序为TP-rq>TP-qhd>TP-ga>TP-sd,该结果与感官评价具有较好的一致性。重复实验表明压缩模式下体膨颗粒质构评价曲线具有峰型一致、重复性好、区分度高的特点,第一循环硬度可作为体膨颗粒强度评价的指标之一,可定量表征膨胀倍数与强度之间的关系,为现场应用提供定量依据。

Abstract: Based upon similarity between characteristics of profile control and water plugging product and food industry product (such as gelatin),the texture analyzing method,which was conventionally used for product performance evaluation in food industry,was introduced to conduct the exploration for quantitative strength evaluation of profile control and water plugging agent.Texture analysis for 4 kinds of grain swelling profile agents with different swelling multiple was conducted using a CT-3 texture analyzer.Under compression mode,data for parameters such as hardness cycle 1 standing for strength and the deformation corresponding to the hardness et al.were obtained.The results showed that the sequence of strength data of the 4 kinds of profile control and water plugging agent is TP-rq>TP-qhd>TP-ga>TP-sd.The results are rather well consistent with the results from sense organ evaluation.Repeated tests showed that under compression mode,the peak type in the grain swelling profile evaluation graph displays consistency good repeatability and discrimination.The hardness cycle 1 could be used as one of the critical indices for the evaluation of strength of the grain swelling profile agent;to quantitatively characterize the relationship between swelling multiples and the strength;and to provide a quantitative basis for application in crude oilfields.

Key words: profile control and water plugging agent, grain swelling profile agent, strength evaluation method, texture evaluation
