微胶囊技术在油田化学中的应用进展
Advances in the Application of Microcapsule Technology in Oilfield Chemistry
摘要
Abstract
As oil and gas exploration extends to deep reservoirs,unconventional resources and other fields,formation conditions have become increasingly demanding.Operations such as well drilling,well completion,fracturing and acidizing are faced with greater challenges,imposing higher demands on oilfield chemical additives.As an efficient and smart means of material encapsulation and controlled release,microcapsule technology provides an important approach to the solution of technical challenges in oilfield chemistry.This paper systematically introduces key parameters of microcapsules such as their structural characteristics,particle size,micromorphology,encapsulation efficiency,and mechanical property etc.,and discusses industrial production methods with promising application prospects and controllable costs.It focuses on reviewing the research and application advances of microcapsule technology in targeted lubrication of drilling and completion fluids,phase change temperature control,lost circulation prevention and control,self-healing of well cement sheath,corrosion inhibition,gel breaking of fracturing fluids,and sustained-release acidizing etc.Based on the current complex formation conditions,key problems of microcapsules are analyzed,such as insufficient stability,poor release controllability and difficulties in large-scale production.Directions of future development in microcapsule technology are prospected,including the design of high-performance wall-building materials,the development of multi-responsive microcapsules,the investigation of multi-factor release mechanisms,and low-cost green production processes.It is expected to provide references for the efficient,environmentally-friendly and intelligent development of oilfield chemical additives.关键词
