Has large reserves of low abundance , poor physical properties , and other characteristics of the difficulty of developing low permeability reserves onshore oil industry has become China's major potential for stable development , sustainable development of the oil industry is the future technology direction . How to develop reasonable and effective permeability , low permeability reservoir is an important research topic . Wu Qi Wu 420 well area oilfield reservoir with low permeability , low permeability in common , carried out on Miss 420 well area low permeability reservoir development and technological measures , not only for the effective development of Wu District 420 wells to provide technical support, but also similar reservoir development can provide important reference value and significance . Geological characteristics of the reservoir for the development process as well as the problems , the paper mainly studies carried out in the following aspects and obtain the corresponding results : 1 ) for NG 420 well area WUQI oilfield reservoir exploration and development of regional geological background and profiles a brief introduction, analysis of reservoir characteristics of early production ; and oilfield reservoir distribution , reservoir thermodynamic conditions , reservoir fluid properties , reservoir natural energy and drive type , capacity and oil absorption capacity of wells , reservoirs various properties studies were analyzed . 2 ) use of reservoir engineering analysis methods, from rational development of strata , well type , well spacing , reasonable oil production fluid strength , rational exploitation rate , reasonable injection strength, formation pressure to maintain a reasonable level of reasonable injection ratio and other indicators , the study identifies the 420 well area WUQI oilfield Wu developed technology policy boundaries. 3 ) using numerical simulation method to predict different injection patterns , well spacing , injection timing , production pressure , fluid production rate under the conditions of the development of indicators , preferably the 420 well area WUQI oilfield Wu reasonable development plan and reservoir rational development of technology policy, given optimal reservoir development program to develop dynamic indicators forecast results.
