The parameters of reservoir impact all the sectors of oilfield developing after flood development, so methods of separate stratum injection allocation are researched for forecasting the petroleum reservoir performance accurately. The methods of separate stratum injection allocation are significative for remaining oil distribution, injection allocation of interval and the level of exploitation and administration in high water cut stage. First, we should derive injection-withdrawal ratio (IWR), gradient of pressure and water cut by material balance equation.The injection allocation of single well,injection wells and property of interval are determined by the research of split coefficient.We find the reservoir small error, lower water cut, high degree of reservoir recovery by anaysising the results of separate stratum injection allocation.The results show that separate stratum injection allocation is scientific and reasonable, simple and applied for the oil field in high water cut stage.

During the development of the oilfield, the water cut of the water controlled field is an aggregative indicator which is affected by various factors. It can reflect the restriction of liquid flowing rules from the oil layer and crude oil physical property, and the effect of serious technical measures during the exploitation. Water cut increasing rate is closely related with water cut. The level of water-cut increasing rate of various well network was evaluated during oil producing with extra-high water cut in Xingnan development area, compared the differences among various well networks, and analyzed the geology causes and development causes.

This paper has discussed the characteristics, roles, feasibility and obvious effects of the technology by applying electric field to enhance oil recovery when the oil field is in high water cut stage and super high water cut stage. In view that most oil wells in old oil field have entered into the super high water cut production, the remaining oil in the main reservoir is in fragmented distribution with poor results of water injection and new reserves of oil mostly have a low penetration rate and are thin layers of poor physical properties, the use of the direct current field in period of high water cut is the best policy to achieve high and stable yield and is fairly promising.

Water Cut

East Xing Six District of Daqing oilfield development has 50 years of history, the block has entered high well density, high water cut stage. The apricot East Xing Six District demonstration zone development belongs to the continental sedimentary system, it has reservoir types and physical properties have large differences, It was long-term effected by injected water, after water flooding, water degree condition becomes very complex and unpredictable, so the washing condition analysis is an important guarantee for Daqing oilfield stable production. Using the oil field sealed coring well data, various types of reservoirs washing degree thickness change and growth are analyzed, We can know that with the further water flooding development and well pattern infilling, all kinds of oil reservoir production status; and then analyzes the potential distribution of the oilfields, and provides a basis for the development of the block and the adjustment of the next step of work, has an important guiding significance.

The Relationship

Development characteristics of oil field during production-decreasing stage were analyzed in this paper. The ultimate recovery factor can be determined at a limit of oil production rate by investigating the relationship between production rate and recovery percent. Some physical conditions were given. Based on the mass conservation principal and seepage mechanics method, it was found that the recovery degree varies versus production rate linearly. The model prediction using the actual data of west Ng63+4oil strata in Gudong 7 region, a reservoir in Shengli oilfield of China, was performed. The results demonstrated that the linear model had well estimation of the recoverable recovery of oil fields which were at the later period of high water cut stage.

Measure of plugging water refers to through sealing high water formation to slow down the contradiction between lays, so as to increase the liquid production of low water formation and to increase the swept volume the extent of reserves producing. It is an important measure that aims at the rapid increasing of liquid-oil ratio in late stage of high water-cut, to keep the stable production of oil field. It is an effective measure to reduce and control the useless water production rate which not only can increase the fluid production sensibly but also can slow down the production decline and guarantee the economic rationality in oilfield development. Field practice has proved that the measure of plugging water has a better guiding significance to the reservoir in late high or extra high water-cut stage. Through analyzing the effect of plugging water, and a comprehensive evaluation of the effect of plugging water, we can find out the key factors that affect the measures of plugging water, which has a better guiding significance to maximize the high water cut oilfield development profit.
