A | CANBERRA, Australia -- Australian journalist Cheng Lei says she spent more than three years in detention in China for breaking an embargo with a television broadcast on a state-run TV network.Cheng‘s first television interview since she was freed was broadcast in Australia on Tuesday almost a week after she returned to her mother and two children, aged 11 and 14, in the city of Melbourne.The Chinese-born 48-year-old was an English-language anchor for state-run China Global Television Network in Beijing when she was detained in August 2020.She said her offense was breaking a government-imposed embargo by a few minutes following a briefing by officials.Her treatment in custody was designed to “drive home that point that in China that is a big sin,” Cheng told Sky News Australia. “That you have hurt the motherland and that the state’s authority has been eroded because of you.” “What seems innocuous to us here is –- I’m sure it’s not limited to embargoes, but many other things -- are not in China, especially (because) I’m given to understand that the gambit of state security is widening,” she said.Cheng did not give details about the embargo breach.Her account differs from the crime outlined by China’s Ministry of State Security last week.The ministry said Cheng was approached by a foreign organization in May 2020 and provided them with state secrets she had obtained on the job in violation of a confidentiality clause signed with her employer. A police statement did not name the organization or say what the secrets were.A Beijing court convicted her of illegally providing state secrets abroad and she was sentenced to two years and 11 months, the statement said. She was deported after the sentencing because of the time she had already spent in detention.Observers suspect the real reason Cheng was released was persistent lobbying from the Australian government and Prime Minister Anthony Albanese’s planned trip to China this year on a date yet to be set.Cheng said that a visit to a toilet at the court on the morning before she was sentenced was the first time in more than three years that she had sat on a toilet or seen her reflection in a mirror.Her commercial airline flight from Beijing to Melbourne was the first time she had slept in darkness in three years because the lights were always left on at night in the detention facilities.Cheng migrated to Australia with her parents at age 10. She said she struggles to answer when asked how she has been since her return.“Sometimes I fell like an invalid, like a newborn and very fragile,” Cheng said. “And other times I feel like I could fly and I want to embrace everything and I enjoy everything so intensely and savor it.”。 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。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。
B | 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。
