【摘要】 在井场生产作业过程中,气测全烃参数所受主客观影响因素较多,测量值在实际应用中误差很大,导致其在解释评价中功用受限。为了解决这个问题,提高气测全烃参数预测的可靠性,针对不同气体来源的各种影响因素,分析气测全烃的主要影响因素及其与气测全烃之间的相互关系,建立了气测全烃修正方法和数据点优化方法,并基于实用性对其进行简化,最终形成一套适应性广泛、操作简便的气测全烃修正方法。所建立的方法在涪陵页岩气主体区取得了很好的应用效果,为评价储集层含气性提供了新的方法和手段。更多还原

【Abstract】 Many subjective and objective factors affect the parameters of total hydrocarbon in gas logging in the production on well site,and the measured value has a large error in actual application,which limits its function in interpretation and evaluation.To solve this problem and improve the reliability of predicting the parameters of total hydrocarbon in gas logging,various influencing factors of different gas sources are used to analyze the main influencing factors of total hydrocarbon in gas logging and their relationship with total hydrocarbon in gas logging.Correction method and data point optimization method of total hydrocarbon in gas logging are established and simplified based on practicability.Finally a set of correction methods for total hydrocarbon in gas logging with wide adaptability and simple operation are formed,which achieve good application effect in the main shale gas area in Fuling,providing a new method for evaluating the gas-bearing of reservoirs.更多还原
