热蒸发烃色谱分析技术在胜利油田油气勘探中的应用

The application of thermal evaporating hydrocarbon chromatographic analytical technology in oil and gas exploration in Shengli Oilfield

储集层产液性质判定及真假油气显示识别一直是油气勘探开发过程中的难点问题,录井技术的发展和进步为解决这些难点问题提供了切实有效的手段。详细介绍了热蒸发烃色谱分析技术的发展、原理以及在胜利油田油气勘探中的应用情况和效果。热蒸发烃色谱分析技术是一种应用于油气检测的烃类组分细分方法,可以根据单体烃的变化对储集层的原油性质、油水特征等进行评价,从而能有效判别产液性质、区分真假油气显示。近几年在胜利油田的实际应用效果表明,该项技术对快速判断油层、油水同层、含油水层、水层等流体性质方面有较高的准确性,并在真假油气显示识别方面有其独特的优势,是录井新技术体系中一种不可或缺的有效方法。

The judgment for the reservoir fluid properties and distinguishing of true or false oil and gas shows are always the key problems during oil and gas exploration and development, the development and advancement of drilling fluid logging technology has provided practical and effective measures for solving such key problems. The paper introduces the development, principles of thermal evaporating hydrocarbon chromatographic analytical technology and its application effects in oil and gas exploration in Shengli Oilfield. The thermal evaporating hydrocarbon chromatographic analytical technology is the subdivision method for hydrocarbon components in oil and gas detection, which can evaluate reservoir oil properties, oil and gas characteristics according to the single hydrocarbon variation; therefore the reservoir fluid properties and the true or false oil and gas shows can be judged and distinguished effectively. The practical application results in recent years in Shengli Oilfield have indicated that the technology has the higher accuracy in the aspects of fast judging fluid properties of oil bed, oil-water bed, oil bearing water bed and water bed, owns its unique advantages in distinguishing of true or false oil and gas shows and is the necessary effective method.
