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
