摘要:
针对G油田注水开发的特点,依托不同含油状态下常规测井和地化录井分析的响应特征为基础,确定以测井曲线中深、中、浅电阻率组合来识别水淹层为主体,通过测井响应计算的地化录井敏感参数划分弱-中水淹和强水淹两类,最后结合电阻率与饱和度的“U”关系中,选取合适的含水饱和度值,并与束缚水饱和度交会,细化水淹等级,建立弱、中、强三类水淹等级划分标准。采用该方法对12口井进行了水淹层精细评价,经过7口新井检验,解释符合率为81.25%,其评价结果能满足实际生产需要。
Abstract:
According to the characteristics of water injection development of G Oilfield,based on the characteristics of logging and geochemical logging under the condition of different oil saturations,a method was proposed to identify the water-flooded layer by the combination of deep,medium and shallow electrical resistivities in logging curves.And then two types of week-medium and strong water-flooded layers were divided by geochemical logging sensitive parameters calculated through logging responses.Finally,combined with the "U" relationship of resistivity and saturation,selecting the appropriate water saturation value,and intersected with the irreducible water saturation,it was established that the classification standards of the week,medium and strong water-flooded layers.The method was used in the fine evaluation of the water-flooded layers of 12 wells in G oilfield.After tests in 7 new wells,the interpretation coincidence rate was 81.25%,and the evaluation results can meet the needs of production.
