【摘要】 杏树岗地区以开采中浅层含油气组合为主,但现在已进入高含水开发阶段,储采失衡矛盾突出,迫切需要寻找可接替潜力。杏树岗地区扶余、杨大城子油层有多套油水组合,水性识别难度较大。目前热解、色谱、荧光显微图像、核磁共振等油水层识别评价技术已经很成熟,应用效果较好,已完全具备了准确识别评价储层流体性质的条件,但在该地区没有得到应用,录井技术优势没有得到充分发挥。为将新的录井解释评价技术应用到老区,解决生产急需,提高解释符合率,为采油厂完井方法确定、下一步井位布署、区块储量计算等提供有利依据,以井壁取心、岩心分析为手段的录井油水层识别评价技术推广应用到杏树岗地区扶、杨油层,经过大量实践,结合本区特点,收集40口探井、开发井的76个层录井、测井、试油资料,总结出一套油水层识别评价方法,建立了油水层单项及综合解释标准、图版,并在此基础上对解释方法有所完善,该方法应用到30口井,符合率达到了90%以上,进一步验证了方法的准确性。该研究取得很好的应用效果,并在采油厂的实际工作中,起到了很好地指导作用,获得巨大经济效益。更多还原

【Abstract】 In Xingshugang areas, oil and gas exploration is mainly in shallow layers. But now has entered the high water cut stage, the reserve-production balance outstanding conflicts outstanding and it is an urgent to find a viable alternative to the potential. In Xingshugang regions, there are several sets of Fuyu and Yangdachengzi oil and water mix layers, water-based identification difficult. Pyrolysis, chromatography, fluorescence microscopy images, nuclear magnetic resonance evaluation of oil-water layer recognition technology is mature, fairly effective and is fully equipped to accurately identify the conditions for evaluation of reservoir fluid properties,but all technology are not used in this regions,it is difficult to show the advantage of mud logging technology .We use mud logging technology for the production well to solve the problems of evaluation, and direct the completion of well, provide the information of next well location definition and regional reserve calculation, oil-water layer recognition technology based on sidewall core and core is used in this region, according to the regional condition, collect logging and testing data of the 40 wildcat and production wells, establish a way for oil-water layer recognition, create oil-water layer recognition standard and plate, and use it to new 30 wells, accordant degree increase up to 90%,this prove the correction of technology. Summed up a lot of practice by the water layer pattern recognition method, application to obtain good results, access to a huge economic benefits.更多还原
