近六年未,勘探地球物理学一如既往地在迅速发展。我们进入了一个崭新的时代,勘探方法日趋完善,各种技术的精度有了很大的提高。在重磁勘探方面,出现了新的惯性导航系统。在地表条件极端困难的地区,利用该系统可以指导直升飞机进行作业,它可以采集到极精确的地面重力数据。为了利用直升飞机得到高质量的航空重力勘探数据,技术界已经付出了相当大的努力。在处理和解释电位场资料方面,也有了重大进展。从地震资料中最大限度地提取精确的地下信息早已成为人们向往的目标。为了达到这个目标,人们采用了高采样率的准确的二维、三维陆上勘探技术。结果大大提高了陆上地震勘探的精度。为了更精确地接近一个点震源、点检波器系统,单位记录的检波器道数急剧地增加了(达1024道)。现在功率极大的纵波可控震源,其扫描频率范围在5赫到200赫以上。在海洋勘探中,海洋电缆和船上的仪器也有新的突破,记录和处理道数达到96道至480道。在海洋勘探检波器组合和震源组合方面也有了改进。地震资料处理中最大的发展是影像法和反演法,这些不仅是波动方程理论的基础,而且是一种全新的处理方法。波动方程法已被公认为是一种用于迭前偏移、迭后偏移、压制多次波、基准面和位移静校正、速度分析和地震反演的有效工具。反演技术提供了详细的声阻抗或速度近似值,从而得到了广泛的应用。子波处理提高了我们对地层分辨力。一维、二维和三维模型技术更加成熟了,在资料采集和处理的过程中,起了出色的指导作用。在资料的直接解释中,也有很好的效果,并且提出了很多基本释解概念。有些模型系统现在可以处理垂向和横向的速度变化、非弹性衰减、弯曲反射面、穿透边界、时变波形、虚反射、多次波以及组合效应等问题。在资料处理、模拟和解释中,不能低估各种地震资料显示方式及彩色显示的作用,这些技术近期都有所改进。地层解释技术包括下列三个方面: 1.宏观地层,其中分析了区域的和盆地的沉积形状,从而在大范围内划定了地质沉积环境; 2.对地层作定性分析,其中定性分析了特定的岩性单元以及它们的特性,判定出岩性、孔隙度、构造方位、范围和形态; 3.对地层作定量分析,其中在特定的地层上描绘出各种异常,从而确定出完整的孔隙度,气—液界面和可能存在的孔隙填充物。实际上,就是把从直接找气技术演化而来的成果应用到各种不同的地质区域。为了获得更多的有关地层、孔隙度和油气饱和度等方面的信息,人们在直接产生并记录横波方面作了巨大的努力。在进行横波勘探中使用的震源有可控震源、水平冲击震源和炸药震源。自从使用计算机以后,测井技术有了新的发展。现在已经有了井场磁带记录设备和小型计算机,解释算法比较简单。在资料处理中心,已有比较成熟的计算机处理解释方法。1978年,研制成功了一种名叫“小井径”(slimhole.的井口重力仪,且已投入使用。它的精度为20微伽。石油工业对各种电法技术的兴趣在增加,尤其是大地电磁法(MT)和有源电磁(e.)测深技术。改进以后的大地电磁法(MT)仍主要用于普查。由于某些公司使用电磁“反射”测深法在直接找油找气方面获了成功,因而这种方法受到人们的普遍关注。用直接找油找气法有可能找到浅层的有工业价值的储集层,但是对于任何深层目标,其成功的关键在于能否测得油气向上运移后产生的二次效应。

目的:观察细节护理联合加速康复外科理念在手术室护理中的应用及对患者睡眠质量的影响。方法:选取2019年1月至2020年12月厦门大学附属第一医院杏林分院收治的手术患者80例作为研究对象,按照随机数字表法分为观察组和对照组,每组40例。对照组患者给予常规临床护理干预,观察组患者在对照组基础上给予加速康复外科理念护理干预,围绕细节护理展开干预。采用匹兹堡睡眠质量指数(PSQI)比较2组患者干预前后睡眠质量的变化,采用自拟满意程度调查问卷评估2组患者干预后的满意程度,同时比较2组患者的临床护理效果,包括手术时间、术后排气时间、术后排便时间及术后下床活动时间。结果:干预后,观察组手术时间、术后排气时间、术后排便时间及术后下床活动时间均显著短于对照组,观察组总满意度显著高于对照组;2组患者睡眠质量各维度评分均有所降低,且观察组显著低于对照组,2组比较差异有统计学意义(均P<0.05)。结论:相较于常规手术护理而言,细节护理联合加速康复外科理念运用于手术患者中,可有效提高临床护理效果,优化手术患者的睡眠质量,值得在临床护理中使用。
