Panlong Oilfield By Water Flooding Zone Dynamic Analysis Effect Assessment

Panlong oilfield was discovered in 2000,when in the exploration and development under the guidance of policy,started in 2001 by natural energy local stopes.The result shows that because of the low reservoir pressure,formation energy shortage,low oil well production,decreasing speed,average monthly decline rate is 10-11.32%.So,decided to in panlong production plateau region is supported by waterflooding experiment was carried out.As the water flooding development in recent years,many new contradictions,exposed in the production of the rising moisture content such as some effective symmetry,while others did not work well group is complement formation energy,unaccounted for after a large number of injected water into formation and so on.The water flooding development dynamic,therefore,the current top priority is to make scientific analysis,and on this basis,put forward corresponding control measures,reasonable adjustment scheme of the existing water injection,production potential to mining.This project mainly in panlong oilfield plateau area under current production dynamic analysis,mainly from the injection pattern,oilfield stable trend,reservoir energy,and a comprehensive evaluation of degree of water flooding and comprehensive analysis of the development effect,to develop a reasonable waterflood technology adjustment scheme,in the long-term development of oilfield,realize the stable oil field production,high yield and lay the foundation.
