摘要： The invention provides a well treatment composition comprising: a viscoelastic surfactant or a cementing composition and an environmentally friendly component made of cellulosic matrix with organic acid trapped within. A method is disclosed comprising introducing into a wellbore penetrating a subterranean formation an environmentally friendly component made of cellulosic matrix with organic acid trapped within.Also, the invention provides a method for rheology modification optimization of a viscoelastic surfactant, comprising: (a) defining a rheology profile of the viscoelastic surfactant; (b) defining a comparative rheology profile of a composition of the viscoelastic surfactant and a first environmentally friendly naturally occurring component made of cellulosic matrix with organic acid derivative trapped within; (c) repeating step (b) with a second environmentally friendly component made of cellulosic matrix with organic acid derivative trapped within; (d) defining between the first and second environmentally friendly components, environmentally friendly component showing optimum modification of the rheology based on analysis of the rheology profile and comparative rheology profile.
摘要翻译：本发明提供了一种井下处理组合物，其包含：粘弹性表面活性剂或粘合剂组合物和由有机酸捕获在其中的纤维素基质制成的环境友好组分。公开了一种方法，其包括将穿透地下地层的井筒引入由有机酸捕获的纤维素基质制成的环境友好的组分。此外，本发明提供了一种粘弹性表面活性剂的流变改性优化方法，包括：（a）限定粘弹性表面活性剂的流变学特性; （b）限定粘弹性表面活性剂组合物和由有机酸衍生物捕获的由纤维素基质制成的第一环境友好的天然存在的组分的比较流变学特性; （c）用残留有有机酸衍生物的纤维素基质制成的第二种环保组分重复步骤（b）（d）在第一和第二环境友好组分之间限定，基于流变学特征和比较流变学特性分析，显示出对流变性的最佳改性的环境友好组分。
