Oil production can be improved by profile control technologies,including the decrease of the permeability of high permeable zone and the increase of water-flooded sweep efficiency contributions. The most important chemical systems applied in present profile control technologies are weak gel systems with many great merits in promoting oil output. In this paper,we make a summarization on following aspects:The basic component of weak gel systems used in oil exploration by profile control technologies in recent years,the mechanism and condition of the formation of weak gel systems initiated by different crosslinking agents,and the evaluation methods of the performance of weak gel systems. It is also discussed that how additives,including stabilizing agents,bactericides,salt resistances,delay agents,etc.,and environmental factors,such as temperature,salinity,pH,etc., affect the properties of weak gel systems. Based on the current application of weak gel systems,it is pointed out that there are still some problems unsolved in the profile control processes when the weak gel systems are employed. To develop new effective and inexpensive profile control agents and make the corresponding theoretical basis to new agents,methods to investigate the gelling mechanism of weak gel systems need to be improved. The improvement is going to be a transition from traditional macroscopic research methods to microscopic research methods,such as the laser light scattering,atomic force microscope and computer molecular dynamic simulation,etc.
