油井增产措施经济评价   总被引:1,自引:0,他引:1  
油井增产措施是指为了使已开采的油井增产增效,而对油井采取的一项作业工程.增产措施有多种类型,不同措施会带来不同的增产效果,但又都有不同的成本组合.对油井增产措施的经济评价,首先是措施后累积增产量的预测,其次是投资估算和成本估算,最后是对方案进行净收益分析、经济极限分析和敏感性分析.本文给出了某油井的实际评价结果.  相似文献

为长效管理、监测红色砂泥岩中的裂隙-孔隙地下水井,采用B/S模式,以GeoMedia WebMap为WebGIS平台和成都市基础地理数据库为基础,依托成都市国土资源局专网,建成红色砂泥岩中的裂隙-孔隙地下水井数据库,设计并开发了监测与管理信息系统。该系统实现了水井信息的动态更新、跟踪管理、档案查询、统计分析等功能,市、县(区、市)、乡镇三级联动,为红色砂泥岩中的裂隙-孔隙地下水井的管理和决策提供参考和依据。  相似文献

要发现捐赠的人性之美,不能让传统的经济学分析蒙住了眼睛。依靠自己的天赋和努力,通过正当的途径和手段成为巨富的人,是整个社会的精英,更是巨富中的精英,是精英巨富。所有精英巨富都必然是热心的社会捐赠者中的巨鳄,这是由其高尚的财富观所决定的。遗产税的慈善公益捐赠扣除,是极大尊重精英巨富,使其尽情行善的制度,是向去世精英巨富的崇高敬礼,理解这一制度对社会的和谐具有重要的意义。  相似文献

四川九龙山气田为低孔、低渗致密砂岩气藏,储层的孔隙度和渗透率极低,但储层微裂缝较为发育。该区气井进行压裂作业后,出现了支撑剂回流的现象,支撑剂回流导致压裂支撑缝长、缝宽变小,同时也会导致导流能力下降。以单颗粒支撑剂受力分析方法为基础,研究了压裂气井支撑剂回流机理,推导了该区支撑剂发生返排的临界流速;结合改造研究区气藏的施工数据,分析了影响支撑剂回流临界流速的因素,临界流速会随着支撑剂的密度和粒径的增加而增加,而压裂液的黏度降低将会明显增大临界流速;结合工程流体力学和气藏工程原理,建立返排油嘴临界尺寸与返排临界速度的关系,通过井口控制油嘴尺寸来控制压裂液返排速度,形成了一套支撑剂回流控制技术,为现场施工控制压裂液返排提供指导。  相似文献

This study examines the impact of leisure activities on leisure domain and life domain satisfactions and subjective well-being (SWB) and explores the differences between genders in these associations, using data from 316 middle-aged adults. The results suggest that sports and travel & outdoor activities have the greatest impact on physiological, psychological, and relaxing satisfactions. Social activities are key ingredients in social, psychological, and physiological satisfactions as seen by men, whereas cultural activities and hobbies are important in women's psychological satisfaction. While relaxing and social satisfactions are important in men's SWB, psychological satisfaction is the most important factor in women's SWB.  相似文献

Recognizing the increasing importance of sustainable environment, this research explored visitors’ pro-environmental decision-making process in an urban park context. This study investigated the relationships among attitudes, subjective norms, perceived behaviour control, positive and negative anticipated emotions as well as behavioural intentions. The results suggest that positive anticipated affects positively influenced low-effort and high-effort pro-environmental behavioural intentions. In addition, positive anticipated affects mediated the relationship between cognitive factors and behavioural intentions. Interestingly negative anticipated affects did not influence behavioural intentions. Further analysis revealed subjective norm was the strongest predictor of intentions, especially the low-effort pro-environmental behavioural intentions. The research advances the conceptual understanding of the role of each construct in generating park visitors’ intentions to perform environmentally responsible behaviours while visiting an urban park.  相似文献

The purpose of this study is to examine the factors that motivate tourists to engage in collaborative efforts with tourist destinations for the co-creation of innovative tourism products. Targeting tourists who have visited Tokyo for tourism purpose, the study verifies the antecedents of tourists’ intention to co-create, which include perceived benefits (PB), perceived costs (PC), subjective norms, and ability to co-create tourism innovation. This study further reveals that PC do not have a significant impact on tourists’ intention to participate in innovation co-creation activities, while the other antecedents play important roles. Also, separating PB and costs into internal and external factors, perceived internal benefits (PIB) play a significant role in motivating tourists to participate in co-creation, while perceived external benefits do not. Practical implications are provided for destinations such as Japan to encourage tourists to share their valuable knowledge to improve tourism products and services of tourist destinations.  相似文献

Research summary : This study draws on the resource‐based view and the behavioral theory of the firm to gain new insights about the effect of performance relative to aspiration level (i.e., performance feedback) on the decision to enter new markets. Results show an inverted U‐shaped relationship between performance both below and above aspiration level, and the probability of firms to enter new markets. That is, when firms are well below or well above their aspiration level, they significantly change their behavior. This article develops a theoretical framework to clarify and organize these findings. Managerial summary : This study examines the effect of performance feedback, and particularly, large discrepancies between firm performance and aspiration level on the decision to enter new markets. It provides support to the role of performance feedback in affecting the decision to enter new markets, a factor that has received relatively little attention in the extensive literature that has examined the inducements of such moves. Results show that, as performance falls below or rises above aspiration, a firm's probability of entering new markets increases up to a certain point after which this relationship decreases. This shows that the tendency to enter new markets is different for firms that are in the neighborhood of aspiration level compared to those that are well below or above it.

高新技术产业发展是推进地区产业结构优化调整的中坚力量,而高新技术产业的发展也离不开科技金融的有力支撑。本文基于科技金融投入、高新技术产业发展,以及地区产业结构优化三者间的作用机理和传导路径,利用我国30 省2007~2015 年均衡面板数据建立向量自回归模型,实证分析它们之间的动态关系。研究发现,整体来看,变量之间存在单向作用关系,即科技金融投入的增加有助于高新技术产业的发展,进而使产业结构得以优化。但分地区来看,各种原因导致上述作用路径均未能切实到达顶端。基于此,文章最后提出若干对策建议以最大限度地调动三者的动态关联作用。  相似文献
