超深井钻井液用聚合物降滤失剂研究现状及发展趋势
Research status and development trend of polymer fluid loss reducer for ultra-deep drilling fluid
摘要
Abstract
Drilling in ultra-deep formation is faced with complex geological environment such as ultra-high temperature,ultra-high pressure and ultra-high stress,as well as salt paste layer and fractured formation,which leads to conformational changes such as fracture and twisting of key materials such as fluid loss reducer in drilling fluid,resulting in complex situations such as increased fluid loss and deterioration of rheological properties during drilling.Therefore,from the perspectives of optimizing linear polymer molecular structure,and regulating polymer condensed state structure and nano-composite technology,this paper reviewed the research progress of polymer fluid loss reducer for ultra-deep drilling fluid and pointed out the shortcomings of the existing three methods.In addition,it was proposed to use nano micron spherical or hyperbranched tree structure,further study the synergistic mechanism between zwitterionic polymer groups,introduce materials with hydrophobic groups to improve the dispersion stability of nanomaterials,and use molecular simulation combined with laboratory experiments to develop polymer filtration reduction agents with high performance and strong universality.Moreover,artificial intelligence and big data technology should be combined to improve the self-regulation and optimization function of drilling fluid.关键词
