◎ 科技日报记者 操秀英9月14日，随着位于我国南海莺歌海的东方1-1气田东南区乐东块开发项目投入生产，我国自主研发的首套深水水下生产系统正式投入使用，标志着我国深水油气开发关键技术装备研制取得重大突破， 对打造自主可控的海洋油气装备体系、保障国家能源安全具有重要意义。深水水下生产系统是开发海洋油气资源的重要技术装备，由水下井口、水下采油树、水下控制系统、水下多功能管汇等多种复杂水下结构物组成，在低温高压的深海环境中搭建起能够有序传输传送海底油气物流、液压和电气控制信号、水下生产设施状态信息的“多向通道”。    British Defence Secretary Ben Wallace wants a major hike in armed forces spending in response to the conflict in Ukraine.,The BBC reported that Wallace will call on Chancellor of the exchequer Rishi Sunak to raise defense spending from around two per cent of GDP — the NATO target figure — to 2.5 percent.,The minister is expected to make comments to that effect when he addresses the Royal United Services Institute (RUSI) Land Warfare Conference in Westminster later on Tuesday, before flying to Madrid for the NATO summit there.,"The defense secretary is expected to emphasize that now that the threat has changed, governments must be prepared to invest to keep us safe," said a defense source quoted by Sky News.,"We do not comment on alleged leaks," another defense source insisted, adding: "The defense secretary and the prime minister have always said that the government will respond to any changes in threat, which is why in 2020 the Ministry of Defence received a record defense settlement.",Britain has sent a battalion-sized force of soldiers to Estonia in a bid to confront Russia, while supplying Ukraine with thousands of man-portable anti-tank and anti-aircraft weapons, over 120 armored vehicles and three M270 multiple-launch rocket artillery systems.,Wallace claimed earlier in June that Western military aid was helping the Ukrainian military make "significant progress" in the east of the country against Russian and Donbass forces. But recent days saw the capture of the city of Severodonetsk and a string of smaller settlements in Lugansk, with up to 8,000 Ukrainian troops now trapped in Lisichansk.,British Chief of General Staff General Sir Patrick Sanders told the Royal United Services Institute (RUSI) conference on Tuesday morning that the crisis in Ukraine was "our 1937 moment" — a possible reference to then-prime minister Neville Chamberlain's simultaneous policy of appeasing towards Nazi Germany while re-arming Britain.,Sanders said his focus was on "mobilizing the army to meet the new threat we face", insisting: "The British Army is not mobilizing to provoke war, it is mobilizing to prevent war.",NATO Could Expand Eastern European Battlegroups to Brigade or Division-Size Forces: Report26 June, 15:49 GMT,The general called the scale of the conflict in Ukraine "unprecedented.","In all my years in uniform I haven't known such a clear threat to the principals of sovereignty and democracy and the freedom to live without fear of violence as the brutal aggression of President Putin and his expansionist ambitions," Sanders said.,"This is our 1937 moment," he added. "We are not at war but must act rapidly so that we aren't drawn into one through a failure to contain territorial expansion… I will do everything in my power to ensure that the British Army plays its part in averting war."。

B | “深水水下生产系统是挺进深海油气开发综合实力的集中体现，整套系统目前运行状态良好，水下气井产量达到设计目标。” 中国海油海南分公司总工程师刘书杰介绍说，中国海油立足国内相关产业实际，依托国家科技专项，牵头与16家国内企业及高校开展装备研发制造技术攻关，将海南东方气田群待开发边际气藏作为应用目标，推动国产深水水下生产系统成功研发。此前，我国水下生产系统依赖进口，设备应用面临采办周期长、采购价格高、维修保养难等问题，制约着深海油气资源开发。国产深水水下生产系统的成功研制和应用，可以使很多原本不具备经济效益的深水边际油气藏得到有效开发。中国工程院院士、中国海油首席科学家、项目经理谢玉洪表示，水下生产系统要在超过500米水深的海底稳定生产超过20年，对装备的设计能力和建造工艺要求极高。研发团队经过长期技术攻关，成功掌握了水下生产系统的总体设计、核心零部件国产化制造、装配工艺及海上安装等多项核心技术，该项成果对带动海洋油气装备相关产业发展具有积极意义。据了解，东方1-1气田东南区乐东块开发项目主要生产设施包括2套水下生产系统、2条油气混输海管和2条复合脐带缆，计划投产4口开发井，高峰日产天然气超120万立方米，将进一步增强环海南岛海洋天然气生产集群的能源保障能力。
