Study on geological characteristics of Yan93 and prediction of favorable areas in Youfangzhuang Oilfield
The main oil-bearing strata in Youfangzhuang area of Dingbian Oilfield are Yan93 and Chang 4+52.Yan93 reservoir in the north of the area was put into development as early as the 1990s,and the south began to develop after 2010.However,due to various reasons,it was only used scattered and not developed on a large scale.At present,the area is large,the number of Wells is small,the geological understanding is unclear,and there are some development problems such as low production capacity of production Wells,imperfect injection-production well pattern,low water drive control degree and low reservoir utilization degree,and the understanding of reservoir characteristics and enrichment law needs to be further deepened.Therefore,before the formulation of oilfield development plan,it is necessary to carry out geological characteristics research of Yan93 reservoir group in this area,so as to provide technical support for the formulation of development plan.
