The temperature tuning of BaGa4Se7[BGSe]was demonstrated for the first time,to the best of our knowledge.When the temperature of BGSe(56.3°,0°)was raised from 30℃to 140℃,the idler light under type Ⅰ raised from 3637 nm to 3989 nm,the tunable range reached 352 nm,and △λ2/△T reached 3.20 nm/℃.We calculated the phase matching curve of BGSe when ?and T took different values.The relationship between θ and △λ2/△T was obtained by fixing ? at 0°.The maximum △λ2/△T and its corresponding[θ,?]phase matching type were reported under different fixed λ2(3 μm,3.2 μm,...,5 μm).

以渤海某油田8英寸(1英寸=0.025 4m)柔性软管敷设项目为例,对不同敷设方式、常用船舶资源的软管敷设能力和柔性软管敷设参数进行分析和计算,研究敷设方案的可行性。给出在软管敷设过程中使软管所受拉力较小且满足软管最小弯曲半径要求的入水角度范围,并分别给出在软质海床和硬质海床上弃管时的注意事项。研究内容可为以后类似软管敷设项目提供有效的借鉴。

针对渤海油田就位条件的复杂化给自升式钻井平台在就位作业时带来的升船能力、覆盖能力、防碰避让、插桩安全等问题,即实际作业中经常出现自升式钻井平台作业能力与生产平台实际参数不匹配的问题,总结多年的就位选型经验,建立包括水深、气隙、覆盖能力等指标在内的精准选型计算公式和数学模型。现场应用效果表明,精准选型技术可安全、快速、精准地解决渤海油田自升式钻井平台开发井和调整井安全高效就位技术难题,对渤海海域就位作业具有较好的指导和借鉴意义。
