产能预测及试井设计参数优选方法

Optimize Method for Productivity Forecast and Well Testing Design Parameter

以科学编制试油地质设计、取全取准试油资料为目的,统计整理了1990年以来的探井资料600多层30余种数据。根据大庆探区已有的岩心及井壁取心、钻井液、钻时、测井、试油等技术所取得的参数及试井软件解释得到的地层参数之间的相关性,建立了产能预测、试井设计参数优选动态方法及图版,能够准确预测油气井产能、合理制定油气井工作制度。通过现场应用,取得较好效果。

For objection of compiling oil testing geologic design scientifically and acquiring data fully and accurately, the paper accounts for over 600 layers and 30 types of data since 1990. Based on rock core of Daqing exploration district and relevant between parameters acquired by tech of well bore core, drilling fluid, drilling, logging, oil testing and that gained by well testing soft ware, productivity forecast, dynamic optimize method for oil testing design parameter and plot are built which can foresee productivity of oil well accurately and make the work system reasonably. By field applications of it, a proper result has been reached.
