Research On The Class Of Heavy Oil Development Technology Of Fuyu Oil Field

Expansion of the border region in fuyu oilfield exists some kind of heavy oil, water injection effect is poor. As a result of fuyu oilfield belonging to positive rhythm reservoirs, thermal recovery improves the production speed in some extent, the phenomenon of gas channeling is more serious, there is serious security hidden danger, Water injection occurs obvious viscosity fingering because of the large water-oil mobility ratio of that blocks, the area sweep coefficientis greatly reduced, waterflooding process is poor, in order to further improving the development effect of water injection of this blocks,On the research of technical studies and field tasts of expansion of the border region with fuyu oilfield in east 17 station, the heavy oil viscosity reduction technology can effectively solve water injection problems and slow down contradictions of the kind of heavy oil block in fuyu oilfield, With the successful application of this technology, it is supported about enhancing oil recovery of water injection in fuyu oilfield.This article through to the class of heavy oil development blocks inefficient and development features of reservoir, Analysis of factors influencing the block development effect concrete first,Select viscosity countermeasures according to these factors, and then to the class of heavy oil viscosity reduction mechanism of depth profiling, through experiment contrast to select suitable viscosity agent, and later to a series of scheme design of experimental zone, finally choose the most suitable for the oilfield technical countermeasures of development of heavy oil. And the corresponding for oilfield development of heavy oil block, type of heavy oil development laid a solid foundation for further oilfield, have important guiding significance.
