Reservoir deep profile technology

The technology was first put forward by the United States and large-scale commercial applications. Since the early 1970s, began using the polymer plugging, chemical machine for pellets and profiling technology has developed rapidly, has become a high water cut oil field water flooding effect to improve the dominant technology. Currently, for different reservoir profile control agent developed many types and plugging agent, for example, a polymer gel, particle type, precipitation, and microbial agents and foam and the like. In addition to the development of various types of blocking agent, but also on the water shutoff profile abroad mechanism of decision-making technology, Tracer monitoring technology, construction technology, oil expeller and implantation process is carried out a systematic study of the formation of a relatively complete water shutoff sectional supporting technology. China in recent years have done a lot of work, forming a series of technology, in the colloidal dispersion of solid particles in the gel and the gel has its own characteristics, but technically still a gap with foreign countries.
