苏A区块产量递减规律研究

Study on the Decline Rule of Gas Well Production in Su A Block

为了落实苏A区块产量递减规律,采用Arps产量递减分析法对研究区进行产量递减类型分析、产量递减规律研究,并对研究区气井未来十年产量递减情况进行预测。研究表明:研究区符合衰减式递减规律;气井年递减率随着时间逐渐降低,到2028年不同年度投产井的年递减率在6.2%-10.5%之间。

In order to implementing the decline rule of gas well production in Su A block, the decline type of gas well production in the study area is analyzed and the decline rule is studied by the method of Arps production decline analysis. The production decline situation over the next ten year of the study area is predicted. The research shows that the study area conforms to attenuation diminishing rule. The decline rate of the gas well gradually decreases over time. By 2028, the annual decline rate of the different conmlissioning year well is between6.2~10.5%.
