生产测井与试井联合作业技术

Combined operation technology of production logging and well testing

伊拉克H油田主力层M受层间非均质性等影响,开发过程中层间矛盾突出,单纯的生产测井技术只能监测井筒动态,无法实现对油藏的评价。根据不稳定试井理论,基于传统生产测井仪器,对生产测井作业过程进行优化,提出一套综合运用压力、产能、物性资料,动静态资料相结合进行油藏动态分析及评价的有效方法。定向井F-1井运用该方法定量评价了不同工作制度下的产液剖面及其产能变化规律,以及试井解释渗透率、井底污染及油藏物性等参数,实现了井筒流动与油藏评价的结合。该技术对揭示层间干扰、分析油藏动态特征、评价油藏物性具有重要的意义。

Due to the influence of interlayer heterogeneity,the main reservoir M of H Oilfield in Iraq has the problem of prominent interlayer contradiction in the development process.The production logging technology can only monitor the wellbore performance and cannot realize the reservoir evaluation.Based on the traditional production logging tools and transient well testing theory,the production logging operation process is optimized,and an effective method for reservoir dynamic analysis and evaluation is proposed by comprehensively using pressure,production capacity,physical property data and combining dynamic and static data.In directional Well F-1,this method is used to quantitatively evaluate the fluid production profile and its productivity variation law under different working systems,as well as the permeability of well test interpretation,bottom hole pollution and reservoir physical properties,so as to realize the combination of wellbore flow and reservoir evaluation.This technology is of great significance to reveal interlayer interference,analyze reservoir dynamic characteristics and evaluate reservoir physical properties.
