| Nanniwan oilfield,as well as the majority of oil regions,adopted a development method of water flood pressure keeping.It must be researched and governed owing to its rising water cut and high containing water Wells.This thesis conducts a research and analysis on the water flood development effect in a high-water-cut area in Nanniwan oil production plant.The major research contents of the thesis are as follows:1.Sorting out the fundamental geological information of oil sources in treatment area,recognizing and evaluating characters of oil sources there.2.Conducting dynamic analysis on the development of oilfield.3.Analyzing and evaluating the development effect and current water-flood development plan,and finding out the factors that affect the rapid rise of water flood in oil well and the main problem which affects the development effect.4.Reasonably adjusting the relationship between water flood and oil extraction,confirming an adjustment plan and treatment correspondingly so as to enhance the final recovery efficiency.After a series of research,reservoir comprehensive control project need to improve the injection-production well pattern,adjustment of injection-production relation,optimization of water injection technology and control the injection water quality strictly.The integrated management measures of high containing water Wells mainly include: adjustment of water injection,cycle water injection,adjustment of water injection profile and linear water injection.A scientific and reasonable evaluation on the development effect of water flood development is critical to the effective treatment of high-water-cut well in Nanniwan,in addition,it plays a significant role in improving the water flood development of oil sources and enhancing the final recovery efficiency.Meanwhile,it could be a reference and demostration for water flood development evaluation in other oilfields similar to Nanniwan. |
