脉冲中子全谱饱和度测井在大王庄油田的应用
|
摘要
大王庄油田处于开发后期,掌握剩余油情况至关重要,单一饱和度测井方法难以满足精细解释评价的需要。脉冲中子全谱饱和度测井集碳氧比能谱、氯能谱、中子寿命、氧活化测井技术于一体,一次下井能录取多条测井曲线,在低矿化度、高泥质情况下能准确识别水淹层。文章介绍了脉冲中子全谱饱和度测井原理、技术特点、资料解释原理等,并创新性地把全谱饱和度测井数据与常规测井数据有机结合,分层位制作了大王庄油田的交会解释图版,制定了新的解释标准,显著提高了全谱测井的解释符合率;有效反映了储层剩余油饱和度的变化情况,为识别水淹层、寻找潜力层、确定剩余油分布规律,为油田的挖潜增储提供了可靠依据,发挥了重要作用。
Dawangzhuang oilfield is in the late stage of development, so it is very important to find out the distribution of remaining oil.Saturation logging method alone can't meet the requirements of fine interpretation and evaluation. Pulsed neutron full spectrum saturation logging, integrating C/O spectrum, chlorine spectrum, neutron lifetime and oxygen activation logging technology, can record several logging curves in one trip and identify water-flooded zones accurately under low salinity and high shale content. The principle, technical characteristics and data interpretation principle of pulsed neutron full spectrum saturation logging are introduced, and the full spectrum saturation logging data are creatively combined with conventional logging data, the intersection interpretation chart of different layers in Dawangzhuang oilfield is compiled, and the new interpretation standard is set to significantly improve the coincidence rate of full spectrum logging interpretation.The interpretation results can reflect the variation of remaining oil saturation in reservoir accurately, providing reliable basis for identifying watered-out zones, searching potential zones and figuring out the distribution law of remaining oil. It will be a handy and reliable tool in tapping remaining oil and increasing oil reserves.
