针对泌阳凹陷安棚油气藏特低孔特低渗、单井自然产能低的特点,应用天然裂缝
识别技术和裂缝参数定量确定方法对储层裂缝特征、单井裂缝发育井段、裂缝形成期次及裂缝
分布规律等进行了系统研究,并对产层下限、产层分布、压裂层位选择等方面进行了相关研究,
据此确定了合理开发井距和井排部署方向,充分利用了天然裂缝的有利面,减少或避免了其不
利影响,使特低孔特低渗的安棚油气藏投入了开发,取得了良好的效益。

This paper introduces the ways to recognize natural fracture and determine fracture parameter , including fracture features , cause of formation , distribute law , etc. It also analyzes lower limit of produce layers and selection of fracturing layers , especially supplys suggestion of well network deployment . The positive effects of fractures on water-flooding in Anpeng Oilfield are enhancement of reservoir permeability while adverse effects are canceled.
