摘要:
针对准噶尔盆地西北缘红-车断裂带中浅层降解油藏油气层评价难度大、解释符合率低的现状，从降解油藏录井显示特征入手，充分挖掘气测曲线、地化热解资料信息，运用t检验方法探索开发油气层的敏感参数，建立该类油藏气测填充系数-油丰指数录井解释图版及评价标准。通过对新近完钻的部分探井进行应用，效果较好，具有一定的推广价值。
As it was difficult to evaluate the medium-shallow degradation reservoirs in Hongche Fault Zone on the northwest margin of Junggar Basin, and interpretation coincidence rate was low, through analyzing the characteristics of degraded reservoirs in mud logging, the gas logging curves and geochemical pyrolysis data were fully investigated, the sensitive parameters in hydrocarbon re-servoir identification were explored, and logging interpretation chart of gas logging charging coefficient-oil abundance index and evaluation criterion were established. It is used in some of the newly completed exploration wells, it is valuable for promotion.
