【摘 要】
：
在传统黑油模拟器的基础上引入非线性渗流系数,建立了考虑油相启动压力梯度因素影响的黑油模拟器,研究海上大井距开发条件下稀油油藏的剩余油分布规律与挖潜界限.与常规的Eclipse软件模拟结果相比,考虑稀油油藏启动压力梯度后油藏的井间、层间剩余油富集程度加大.以储量动用程度为标准对该油藏加密、纵向的挖潜界限进行量化,其量值为注采井距400 m以上或者渗透率级差10以上.针对J油田的剩余油富集层位进行识别,并实施了开关层作业,实际单井日增油量达到120 m3.

数据库原理及应用课程是计算机专业核心课,它的特点是实践应用性很强,对高层次应用型、技术型人才的培养意义重大,课程采用线上线下混合式教学模式,课程组经过多年实践,探索出了适合我校学生实际情况的教学模式,提炼出课程思政融入课堂的“四方面六步走”的设计方法,即自然科学类课程,从科学精神、生态文明、职业素养和工匠精神等四方面挖掘思政元素,按着“确定目标——分解知识——挖掘元素——形成案例——选择方法——评价反思”六个步骤将课程思政融入专业课的教学,收到了非常好的教学效果,有一定的推广价值.
Currently,a non-geocentric geodetic coordinate system introduced in 1942 (CS42),based on the Kra-sovsky ellipsoid and the Baltic system of normal heights introduced in 1977,is used for geodetic works in the Republic of Uzbekistan.The development of the GN
The determination of accurate orthometric or normal heights remains one of the main challenges for the geodetic community in Ethiopia.These heights are required for geodetic and geodynamic scientific research as well as for extensive engineering applicati
运用全国内地30个省域2010-2019年的面板数据,基于绿色经济发展(GGDP)水平,利用面板空间杜宾模型分析金融集聚、人力资本结构演进对经济高质量发展的影响.研究表明,金融集聚与人力资本结构演进都对经济高质量发展通常是起促进作用的,而且金融集聚对经济高质量发展的空间溢出效应是较强的.但随着金融集聚程度提高,造成过度金融化,进而导致人力资本结构演进对经济高质量发展水平的正向影响不断减弱.这可能是由于金融集聚的过程中,金融集聚程度得提高吸引了大量接受过较高教育得人力资源进入到金融行业,造成过度金融化,而这
The study of postseismic deformation is important for constraining the viscoelastic properties of the Earth and inverting the post-earthquake process.The levelling survey revealed that the area near Bei-chuan elevated 5.3 cm about two years after the Mw7.
There are many approaches to address geospatial monitoring of pipeline overpasses,among which the most widespread methods are terrestrial laser scanning and total station measurements.However,there is a problem in comparing the geospatial monitoring data
The current stress state of the Earth\'s crust in Central Asia depends entirely on the interaction of the Eurasian plate with the Indian and Arabian plates.Moreover,an essential role in this action is played by the subduction process in the Pamir-Hind K
Clustering filtering is usually a practical method for light detection and ranging (LiDAR) point clouds filtering according to their characteristic attributes.However,the amount of point cloud data is extremely large in practice,making it impossible to cl
This case study evaluates the seasonal variability of the Pearson\'s linear correlation coefficient of land surface temperature (LST) with some spectral indices like NDVI,NDWI,NDBI,and NDBal by using a series of Landsat images for 1991-92,1995-96,1999-0
为了满足四川盆地洛带气田开发中后期的产能需求,针对洛带蓬莱镇组储层展开精细预测研究.通过对几种反演方法的对比,最后选用模型波阻抗反演法进行储层预测.模型波阻抗反演法在储层描述方面具有精度高、细节刻画精细、区域匹配度良好等优势,能够敏锐地捕捉岩性的变化特点、准确地反映储层的平面展布与空间分布状况.
