2024年以来，测试公司凭借升级后的PNN+2.0技术，在油田区域内成功完成剩余油饱和度测井53井次，措施完成46井次，累计增油达6214.3吨。

持续创新，提升新质生产力

饱和度测井项目一直是测试公司的“压箱底”技术，在水淹层评价、寻找潜力层和未动用层、有效识别气层、低阻油气层、低孔低渗储层评价等地质应用方面发挥着重要作用。为提升技术能效，近年来，测试公司在复杂储层流体识别上强化研究，提高仪器的探测深度、耐温指标和测量精度，开创了PNN+和PNN+2.0测井技术，增加了低比高能（氧含量曲线）的录取数据，有效提升了对水淹规律的认识，为油田动态调整和优化开采方案提供了科学依据。

精准测试，提供地层精准数据

测试公司始终坚持“一切测试工作要以满足油气藏勘探开发需要为第一要务”的工作理念，以在生产中录取更准确、最原始资料为己任。在每次施工过程中，饱和度测井是要求以不超过每分钟4米的速度进行。为了保护仪器，每测量五百米仪器需要休息半个小时，整个测井过程非常漫长，操作稍有不当会导致仪器损坏、资料不合格等情况。

“在仪器打靶工作时必须要紧盯电脑，对比观察原射孔层的 Sigma 值和长短源距变化，对于重点井段和问题井段都要及时复测，确保资料准确，尽力为油气藏措施提供可靠依据。”今年刚满28岁的工程班班长单体健是测试公司执行饱和度测井任务的一把好手，对于如何提高资料准确率，他简单说道。

Since 2024, with the upgraded PNN+2.0 technology, the test company has successfully completed 53 remaining oil saturation logging Wells in the field area, and 46 Wells have been completed, with a cumulative oil increase of 6214.3 tons.

Continuous innovation, improve new quality productivity

Saturation logging project has always been the "bottom of the box" technology of testing companies, which plays an important role in the eva luation of waterlogged layer, finding potential and unused layer, effective identification of gas layer, low resistivity oil and gas layer, low porosity and low permeability reservoir eva luation and other geological applications. In order to improve technical energy efficiency, in recent years, testing companies have intensified research on fluid identification in complex reservoirs, improved the detection depth, temperature resistance index and measurement accuracy of instruments, pioneered PNN+ and PNN+2.0 logging technologies, increased the data of low specific high energy (oxygen content curve), and effectively improved the understanding of flooding laws. It provides a scientific basis for the dynamic adjustment of oil field and the optimization of production scheme.

Accurate testing to provide accurate formation data

The test company always adheres to the working concept of "all test work to meet the needs of exploration and development of oil and gas reservoirs as the first priority", and takes it as its responsibility to recruit more accurate and original data in production. Saturation logging is required to be performed at a speed of no more than 4 meters per minute during each construction process. In order to protect the instrument, the instrument needs to rest for half an hour every 500 meters measured. The whole logging process is very long, and a little improper operation will lead to instrument damage and unqualified data.

"When the instrument is shooting, it is necessary to keep an eye on the computer, compare and observe the Sigma value of the original perforated layer and the changes in the short and long source distance, and timely retest the key and problem well sections to ensure the accuracy of the data and try to provide a reliable basis for the reservoir measures." Monomer Jian, who just turned 28 years old this year, is a good hand in the saturation logging task of the test company, and he said simply how to improve the accuracy of the data.
