生物礁气藏普遍渗透率低,平面非均质性强,易受到启动压力梯度、应力敏感等因素的综合影响.为了准确预测气井产能,根据生物礁气藏水平井实际渗流特征,运用拟三维模拟方法、保角变换法和等值渗流阻力法建立了生物礁气藏水平井产能预测模型,对不同水平段长度、裂缝条数、裂缝长度等条件下的气藏产能进行了对比分析.

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.
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.
研究平台柱塞举升工艺在页岩气井钻井中的应用,根据平台井分布、气井生产特征探讨设计参数、柱塞配套工具及施工技术的优化.应用结果显示,平台日维护产量可达13×104 m3,产量月递减率下降,页岩气井恢复平稳生产,排水采气效果显著.
GRACE-based estimates for groundwater storage (GWS) changes in North America substantially depend upon correction of glacial isostatic adjustment (GIA) effects,which are usually removed with GIA models.In this study,GIA effects are eliminated by employing
