6月19日，中油测井运用脉冲中子中子测井技术，高效完成新疆吉木萨尔国家级陆相页岩油示范区水平井JHW035井套后饱和度测试，为单井剩余油评价、区域油藏研究提供了重要依据。这是该技术在国内水平井中的首次应用。

脉冲中子中子测井技术是一种剩余油评价测井技术，可确定油藏剩余油饱和度分布规律，是调整注采方案、提高采收率的重要手段。

水平井页岩油储层可以比作地层下的“夹心饼干”，优质储层就像“夹心饼干”中的奶油层。运用脉冲中子中子测井技术可识别奶油层的剩余油情况，对于后期穿越奶油层“吃”到更多页岩油获得高产具有重要意义。

本次施工的JHW035井是新疆油田吉庆作业区的一口重点高产井。为准确了解该井的变化情况，提供可靠的技术支持，中油测井发挥自主连续油管配套技术优势，因“井”制宜优化井下仪器组合，有效解决了穿电缆连管冲洗循环和测井仪器通信的难题，取全取准全部测井资料，进一步提升了区域产层动态测井支撑水平，为页岩油效益开发提供了可靠依据。

On June 19, China Petroleum Well Logging used pulsed neutron neutron logging technology to efficiently complete the post-casing saturation test of horizontal well JHW035 in Jimsar National continental shale oil Demonstration Zone, Xinjiang, providing an important basis for remaining oil eva luation of a single well and regional reservoir research. This is the first application of this technology in horizontal Wells in China.

Pulsed neutron neutron logging is a kind of residual oil eva luation logging technology, which can determine the distribution law of residual oil saturation, and is an important means to adjust injection and production plan and improve oil recovery.

Horizontal shale oil reservoirs can be compared to the "sandwich cake" under the formation, and high-quality reservoirs are like the cream layer in the "sandwich cake". The remaining oil in the cream layer can be identified by using pulsed neutron neutron logging technology, which is of great significance for "eating" more shale oil through the cream layer in the later period to obtain high yield.

The JHW035 well under construction is a key high-yield well in Jiqing operation area of Xinjiang Oilfield. In order to accurately understand the changes of the well and provide reliable technical support, CNPC logging gives full play to the advantages of independent coiled tubing supporting technology, optimizing the downhole instrument combination due to "well" conditions, effectively solving the problems of cable pipe flushing cycle and logging instrument communication, obtaining all logging data and further improving the regional production layer dynamic logging support level. It provides a reliable basis for the beneficial development of shale oil.
