Pingqiao Oilfield Reservoir Characteristics Research And Favorable Area

Pingqiao oilfield Chang 2 within the scope of whole oil field is widely distributed,and through the test of the Chang 2 layer was good oil and gas shows,and Chang 2 reservoir buried depth,single well productivity is relatively high,has a good exploration prospect.In Ansai oilfield Chang 2 ultra-low permeability reservoir during water flooding.By fracture development,strong heterogeneity,water flooding is very complicated.Especially the profile of single sandbody superimposition,mosaic,caused by injection production relationship is complex,the remaining oil is extremely difficult to describe.In recent years,Ping bridge area reservoir development process has accumulated a large number of dynamic and static data,at the same time to carry out geological,extensive logging,reservoir engineering and reservoir production technology research,made a lot of achievements,but based on the current development of the problems exposed,still lack of detailed system analysis and summary.The reservoir research is the core work of oil and gas exploration and development No,the reservoir has nothing.So aiming at the existing problems,it is necessary to use additional information to carry out the static dynamic,sedimentary microfacies,reservoir heterogeneity,reservoir flow unit segmentation,comprehensive evaluation and research work,on the basis of the favorable areas are selected,in order to enhance the geological knowledge,provide the geological basis for the research and development of residual oil Ping bridge area adjustment of technology policy,efficient development purposes.
