摘要
射孔完井是油气田勘探开发过程中不可缺少的环节,对油气井产能影响很大。通过对射孔完井对产能影响机理的深入研究,找出了各种射孔参数对油气井产能影响的规律。结合涠洲油田的特点,以WZ2井为例分析确定了射孔优化所需的敏感参数,结合射孔工艺、地层条件和开发目的等实际情况,形成了一套科学系统的射孔方案优化设计方法;最终给出涠洲油田开发井的射孔优化设计方案,并对应用效果进行了分析,说明了射孔优化设计在提高油气井产能中所起的作用。
Perforating completion,influencing the productivity of oil and gas well greatly,is absolutely necessary in the exploration and development of oil and gas field.Through further study on the influencing mechanism of perforating completion to productivity,the law of various perforating parameters for the productivity of oil and gas well is found,and the understanding on influencing mechanism of perforating for productivity is improved.In this paper,combining with the characteristic of Weizhou oilfield,taking WZ2 for example,sensitive parameter needed by perforating optimization is confirmed.According to some practical situations such as perforating technology,formation condition,developing aim and so on,a set of scientific and systematic methods for the optimization and design of perforating plan are developed.Finally,the optimization and design plan of perforating for Weizhou oilfield development is determined.Meanwhile,its applying effect and function of improving oil and gas productivity are analyzed and explained respectively.
