Research And Application Of Profile Control Technology In Xinbei Oilfield

New oilfield as a single reservoir of high porosity and permeability structure lithologic reservoir (porosity 29%, permeability 507 mD)has developed a 30-year old oil fields. Oil fields have been entered in the late high water cut (Integrated water content 81.23%, recovery 21.14%), no serious water cycle, graphic conflicts become increasingly prominent in recent years, relying on a partial adjustment, effective water and measures to tap the potential to achieve a stable output, but the old areas seriously affected by the water cycle is not valid, stable, improving increasingly difficult to increase oil recovery, oil field development has seriously affected the results, limiting the improvement of oil recovery.Although the pattern adjustment through the development of short-term conflict mitigation, but the fractured reservoir characteristics of this development led to conflicts still exist, the profile control technology as a supplement to improve water efficiency and improve the technology, has become stable Jilin oil field water control important technical means. Although we have carried out 20 years of research and application, but with the extension of development time, each block of Jilin Oilfield reservoir conditions continue to change, swap a higher profile control requirements, for which we need to start from the practical problems, to find ways to solve problems, and ultimately achieving the purpose of controlling water stable oil.Profile water block technology was successfully developed to improve water use efficiency and increased water velocity, the secondary development of old oil fields, play production, has an important role in its economic and social benefits are enormous.
