Re-understanding And Tapping Potential Research On The Reservoir Structure Of Es₃^5-10 Reservoir In Pucheng Oilfield

In Es₃^5-10 reservoir of Pucheng oilfield is located in PuCheng anticlinal structure,After mining,injection-production scheme,the overall elastic modification,comprehensive control and technical transformation these seven stages,Es₃^5-10 reservoir has entered the stage of development for determining.With the improvement of mining technology,the oil reservoir exploration difficulty increases gradually,the two types of layer exploration is difficult,composite water cut is high,the scattered distribution of reservoirs,various problems such as water oil displacement efficiency decreasesIn this paper,the reservoir structure Es₃^5-10 reservoir was further studied,and also the fault,fault block,sedimentary microfacies,reservoir heterogeneity were analyzed,and the geological structure correspond diachronically.At the same time,the distribution of residual oil and residual oil reservoir potential were analyzed.The ultimate aim is for the study of remaining oil potential in technology provides the theory basis,to overcome the current problems faced in the reservoir development,finally realizes the reservoir production stable high yield.Firstly,the paper studied the geological structure of Es₃^5-10 reservoir,analysis of its characteristics of fault and fault block,to rediscover the construction;analyzed the representative cored Wells of Es₃^5-10 reservoir for single well facies analysis,divided facies types,established sedimentary microfacies and logging facies model,and studed the 32 flow unit partition characteristics of sedimentary microfacies.
