With the exploration and development of technology raised and our country's energy development strategy required, the complexity of the development of oil and gas fields on land has become stable development important potential of our country's oil industry, it's the future technical direction of sustainable development.Pen 5 well field Jurassic Sangonghe reservoir belongs to condensate gas reservoir type which contain bottom water and oil ring, the condensate oil content is middle met low, oil/gas/water distributed from the top down present 'up gas, middle oil, bottom water' model. The reservoir's scale is comparatively large which discovered in 2001 year by Xinjiang Oilfield and placing on production in 2003 year. The early stage of development showed the pressure drop too quickly, the gas wells produce oil and the oil layer exploitation effectiveness is poor. Therefore, without prejudice to the effect of gas reservoir development, considering gas cap, bottom water affect on the oil ring development, formulate the oil ring effective countermeasures has become really important.Thesis from the Pen 5 well field Jurassic Sangonghe reservoir's distribution, reservoir characteristics and flow properties of oil, gas and water distribution study, on the basis of having a comprehensive understanding of geological characteristics of Pen 5 reservoirs using reservoir performance analysis, detailed analysis of the gas / oil wells and the entire oil / gas reservoir development dynamic characteristics and the mechanism of exploitation and application the reservoir engineering combining numerical simulation method to study the oil ring's adaptive development through development models including the oil ring to fight infill drilling, oil and gas interface implemented injection barrier and using gas cap energy. Such as research and feasibility studies through the system come: because of the small thickness of the oil ring and the gas cap, the combined effect of bottom water, the oil ring's water flood development and water-flooding development barriers effectiveness are not ideal, but to maintain the gas cap at the current pace, we can encryption 4 wells at good places, this will not affect the gas cap recovery and can also raises the recovery of oil ring from 2.36 percent to 5.36 percent.In this paper, the results of the studies have important guide sense and practical application value for achieving Pen5 reservoir's high and stable yield and lift the production effectiveness of oil layer. The conclusions can also offer theory reference for this type reservoir's advisable development.
