一 |     Near Lyman, Ukraine — At a secret hide-out deep in a forest near the eastern city of Lyman, Ukrainian forces were caught in the crosshairs of a new line of Russian attack. Our CBS News team huddled in the dugout with the troops, not far from the eastern front line, where Russia was putting them under intense pressure with a barrage of artillery in a bid to stretch Ukraine's resources. Moscow wants to force the Ukrainians to bolster their defenses in the area by pulling soldiers away from their counteroffensive in the south. "We've got a couple of weeks now of very huge combats," U.S.-trained Commander Simon Solatenko told us. He and his elite troops from the Bogun Brigade had been up all night, fending off another Russian assault.

     They're outmanned and outgunned. The Russian forces have almost 10 times more ammunition.

"They outnumber us with drones. It's a huge problem," Solatenko told us. "But we are fighting… We have no other choice."                 He's lost a friend in the battle, and he's exhausted. "We're holding our line," he told us with a deep sigh. "It is difficult. I can't say our morale is on the top, but we are holding our line and we are standing."The fighting was so close you could smell the gunpowder, Solatenko told us, but they managed yet again to send the Russian soldiers running back in the opposite direction.One thing that has made a difference further along the front line in the region are the U.S. supplied, and controversial, cluster munitions. The Biden administration agreed to send the weapons earlier this summer, as Ukraine's ammunition shortages threatened its counteroffensive.Critics of that decision worry about a weapon that releases dozens of smaller "bomblets," which sometimes fail to explode — posing a deadly threat to civilians as they can linger on the ground long after a conflict ends. That risk has seen more than 120 countries ban the use of the weapons, but not Russia, Ukraine or the United States.                      Commander Musikant of the Bogun Brigade's artillery unit told CBS News they give his forces a crucial advantage: In the absence of air power, cluster munitions enable Ukrainian troops to clear an area quickly, as they can strike a large section of ground using a single shell.We watched as he directed a strike from their control room. With Russian positions in the firing line, Musikant gave the order to unleash one cluster bomb. The gunner out in the field received the order and let it fly, and then he and his men hotfooted it out of there — firing a shell can reveal their position, and they too can become targets.

The hit was successful.The moral dilemma of using a weapon banned by most countries is not up for debate on the battlefields of Ukraine. The men trying to fend off Russia's invasion believe the cluster bombs are crucial to helping them hold the line, at least for now.The Ukrainian soldiers who spoke to CBS News said the "dud rate" — the number of bomblets that fail to explode — on the American cluster munitions has been very low, claiming they've been almost 100% efficient.White House National Security Council spokesman John Kirby said in July that Ukraine was putting the weapons to use "appropriately."Russia, too, has relied on the controversial bombs during its invasion, and U.S. officials say Moscow has used older versions, with higher dud rates.                                      。      8月25日,我国首条海上油田化学驱聚合物全自动生产线在天津南港工业区开工建设。

二 | 项目建成后,中国海上油田化学驱核心药剂——聚合物将实现自主规模化生产。  该项目是继2021年油田化工南港化工厂建成投产后,中国海油在油田化学品领域的又一重要布局。南港化工厂自投产以来,HAILOONG CHEMICAL(“海龙”化学)品牌油田化学药剂已达18种,配方自主化率达95%,年供应量突破4.36万吨,全面服务中国海上油田并远销海外。此次开工的油田化工南港建设项目,聚焦化学驱聚合物,是南港化工厂基础上的技术升级与产能拓展。  化学驱是海上油田提高采收率的关键技术,其中聚合物驱应用最为广泛。其原理是将高分子聚合物溶于水后注入地层,通过增大溶液黏度,使驱替液在地下更均匀地推进,从而有效驱出常规水驱后残留的原油。聚合物产品的品质与稳定供应,是化学驱规模化实施的重要保障。  油田化工南港建设项目占地121.54亩,年设计总产能5.8万吨,建设干粉聚合物、乳液聚合物等6条生产线,可生产速溶耐盐聚合物、耐温耐盐聚合物、聚丙烯酰胺乳液等全系列产品。项目建成后,将与南港化工厂形成中国海油规模最大的油田化学品生产基地,为增储上产提供资源保障。  项目计划2027年9月机械完工。生产线配置分布式控制系统,实现从原料投加到成品包装全流程自动化精准管控,工艺数据全程可追溯。此前,南港化工厂已获评天津市“先进级”智能工厂,正向“卓越级”智能工厂迈进,该项目的建设将推动中国海油油田化学品智能制造水平跃升。
