The Overall System Adjustment Research Of High Water Cut Stage Of Niuxintuo Petroleum Reservoir

In the past few years, alone with the raise of degree of exploration activity in Liaohe Oil Field, the space which can be explored become smaller and smaller and the explore become more difficult . The achieved of the replace of the outcome was main depended on the internal tap the latent power in the maturing field especially with the heighten of water content in water flood field ,the degree of reserve recovery of subsurface crude oil become more but the distribution of remaining oil become more uneven. So the research of remaining oil has become the main assignment of reservoir management of the intermediary and later stage of development of the maturing field ,it's an important measure of the regulation of the water flooding regime of the water flood field。The original is main to in view of the develop contradiction of Niuxintuo petroleum reservoir low permeability heavy crude reservoir high water cut stage , Geological characteristics of the reservoir re-understanding, including structures, fault contrast to the composition and structure, such as micro-structural characteristics, sedimentation patterns, sedimentary microfacies, the direction of source characteristics, such as sedimentary facies, reservoir lithology, physical properties of the vertical plane distribution, etc, as well as insulating the distribution of reservoir characteristics, fluid properties and distribution, oil, gas and water distribution and reservoir type, complex operators such as reserves, through the above-mentioned study, to understand the reservoir structure, sedimentary facies and reservoirs and other geological characteristics of the relationship with the well productivity. the openShow reservoir engineering evaluation, including evaluation of water effects, the development of department level and pattern adaptation, mines and water temperature forecast ultimate recovery.According to the research of remain oil such as develop the evaluate of petroleum reservoir engineering and use mathematical statistics, the oil saturation of single well, dynamic analysis etc, research distribution of the remaining oil on quality and ration, evaluate the potence of the remaining oil ,then have an arrangement to relevant tap the latent power and a line of develop and regulate technique. The research fruit canbe guided us to design and regulate the same reservoir water flooding program。...
