摘要
聚合物凝胶堵剂在解决钻井过程中出现的漏失现象时,具有高黏弹性、可变形性的优势,综述了常规聚合物凝胶堵剂和“智能”聚合物凝胶堵剂的最新进展。其中,常规聚合物凝胶堵漏材料成胶时间不可控,无法实现高效精准堵漏,而“智能”聚合物凝胶材料能够以多种机理实现高效、精准堵漏,日益成为当下堵漏材料研究的热点。今后,具有刺激响应功能的聚合物凝胶的研究将成为堵漏材料领域的重要方向之一。
Polymer gel lost circulation materials(LCMs)have the advantages of high viscoelasticity and deformability in mud loss control.Generally,there are two kinds of polymer gel LCMs,one is the conventional polymer gel LCMs and the other,the so-called“intelligent”polymer gel LCMs.When use the conventional polymer gel LCMs to control mud losses,the gelling time of the polymer gel is not controllable,and therefore the losses of muds or other work fluids cannot be stopped efficiently and accurately.On the other hand,the“intelligent”polymer gel can be used to efficiently and accurately stop the mud losses based on many different mechanisms,and are therefore under investigation as a hotspot LCM.It can be expected that the stimuli-responsive polymer gel will become one of the important fields in which LCMs are studied.
