【摘要】 喇嘛甸油田已进入特高含水期,开发利用气顶及缓冲区时机成熟。为编制开发试验方案提供可靠依据,为喇嘛甸油田气顶及缓冲区全面投入开发做好技术准备,避免测井资料的单一性,设计井壁取心45口井,在进行水淹层解释的同时,应用井壁取心各项分析资料识别气层及判断油气界面。探讨了井壁取心分析资料辅助判断气层的方法,得出地化及荧光显微图像虽然不能作为判断气层的直接依据,但能够为判断气层提供佐证,在今后的工作中可以借鉴。更多还原

【Abstract】 Lamadian oilfield has been into extra high water cut stage,it is time to develop gas caps and buffer zones.In order to provide reliable criteria for early production system and avoid unicity of well logging data,45 wells for sidewall coring have been designed.Besides water flooded layer interpretation,gas cap identification and GOC determination have been established based on sidewall coring data to make technical preparation for the comprehensive production of gas caps and buffer zones in Lamadian oilfield.The method of applying sidewall coring data to gas layer identification is discussed in this paper.It is found although Geo-chemical chromatogram and fluorescent microgram can not be taken as the direct basis to identify gas layers,they can provide proof for gas layer determination,and they can be as references for the work in the near future.更多还原
