预交联凝胶颗粒膨胀性能的影响因素
Study on expansion property of pre-crosslinked particle gel with low elasticity and high viscosity
摘要
Abstract
In recent years ,because high water content and water channeling have become ma‐jor problems in oilfield ,pre‐crosslinked particle gel (PPG ) technology has become one of high‐speed growing deep flooding technology .Weighing method was used to study the expansion prop‐erties of PPG .The effects of PPG preparation conditions and external environmental factors on expansion property of particles were analyzed completely .The experimental results show that ,at the PPG preparation conditions ,as the increase of mass fraction of acrylamide and crosslinking a‐gent ,and the decrease of mass fraction of the initiator , the particle expansion ratio decreases gradually ;as the increase of surfactant and ionic content ,the particle expansion ratio decreases ;as the increase of temperature and pH value ,the expansion ratio of the particles also increase .关键词
