Application of perforating optimization technology in Weizhou oilfield

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.
