| The Bailangcheng Oilfield of the Hengshan Oil Production Plant has developed over 10 years.The deep-seated problems in oilfield are revealed.It is not clear for accurate resource situation and development potence in oilfield;The oil-water distribution rule of oilfield is not clear;The distribution characteristics of the although and sideway heterogeneities of the reservoir are not clear,so it is diffcult to make a more rational development model.The paper built three dimensional geological model of Chang 2~2 reservoir in Bailangcheng Oilfield according with geological basic problems of the research area,so that it has practical significance on oilfield later development deploy and further adjusting potential tapping.Chang 2~2 formation of the Bailangcheng Oilfield is confirmed as the main producing proof.In view of the oilfield has entered the stage of development and adjustment,in order to improve the oilfield injection-production ratio and maximize water drive producing degree,it must be subdivided into unit.Based on chang2~2 of the Bailangcheng Oilfield of the Hengshan Oil Production Plant,the paper is constucted by the base of the reservoir knowledge and the actual production,researched delicate microtectonics,monosandbodies,sedimentary micro facies,three dimensional geological model of Chang 2~2 formation,calculated oil reserves,defined orientation of development,then the purpuse of improving the development effect,achieving virtuous cycle and enhancing recovery of the oilfield are achieved.The research aimed to reveal the type and distribution characteristics of oil and gas of the Bailangcheng Oilfield,and make a comprehensive evaluation for reservoir.It is a necessary requirement to achieve sustainable development of the Bailangcheng Oilfield.It provides a more reliable basis for further comprehensive adjustment and management,improving the effect of oilfield development,enhancing oil recovery,finally lay the foundation for later development and deployment of the oilfield. |
