摘要:压力是气井和气藏生产动态分析的灵魂,很多动态分析方法都与压力有着直接的联系。然而,由于致密低渗透气藏产量低、压力下降快、关井压力恢复缓慢等生产特征,以及生产方式的限制,在生产过程中很难获得气井或气藏地层压力资料。压降法、产量不稳定分析法和产量递减曲线分析方法是气藏常用的气井生产动态分析方法,但由于地层压力资料缺乏,压降法和产量不稳定分析法也都受到了很大的限制,在衰减递减曲线分析方法的基础上对其进行修正,摆脱了压力资料的限制,通过和压降法对比分析,验证了修正衰减曲线分析方法在生产动态分析中的可靠性。 相似文献

The New Rural Cooperative Medi-cal System ( hereafter NRCMS) in Tibetan areas of Sichuan was started in Wenchuan in 2005 , and by 2008 covered all of the province’s Tibetan areas. This paper studies the effects of the NRCMS on im-proving the health of and alleviating poverty for farmers and herdsmen in Tibetan area of Sichuan. Most parts of the Tibetan areas of Sichuan are located in high altitude districts. Thirty two coun-ties of these areas are classified as “National Pov-erty Counties”. Poverty and disease go hand in hand in these regions. Kashin-Beck disease and hydatid disease are the major endemics in the pas-toral and agro-pastoral areas of Sichuan. Endemic, infectious and chronic diseases are widespread in Sichuan’s Tibetan areas. More than 70% of pa-tients are workers from 20 to 60 years old. Disea-ses are more prevalent in women than in men. Kashin-Beck disease and hydatid disease are cur-rently incurable. Patients suffer from health prob-lems, which leads to a decrease in their income and the heavy burden of medical expenses. The new rural cooperative medical system alleviates the negative effects of farmers’ falling into, or back in-to poverty due to disease. However, the existing medical compensation mechanism is not sufficient to solve the problem. The greatest impact of NRCMS on the farmers and herdsmen in Sichuan’s Tibetan areas is that the system has gradually changed local people’s medi-cal behavior, as well as their underlying ideas a-bout medicine: they begin to believe in hospitals. In particular, more pregnant women are choosing to give birth in hospitals, which reduces the rate of infant mortality and postpartum diseases, and im-proves the health of women. Since the full coverage of the NRCMS in 2008 , the number of people participating in the system has reached the overall average level of Si-chuan province. By analyzing the data before and after the implementation of this system, and meas-uring the impact of the system on people’s health, it can be found that the NRCMS’s role in serving the vulnerable population, such as the elderly and infant children, is more marked. Since the implementation of the NRCMS, all administrative villages in Sichuan Tibetan areas have established village clinics, which solved the problem of a shortage of medicines and doctors in those areas. Farmers and herdsmen have conven-ient access to medical treatment, enhancing the ac-cessibility of medical service. After the implemen-tation of the NRCMS, the health of the elderly population in rural areas has improved. Infant mor-tality rates have dramatically fallen. The implementation of the NRCMS improved the medical service capacity of township hospitals and village clinics. And the NRCMS has brought the township hospitals and village clinics into its scope of compensation, which greatly promotes the utilization of primary medical services in Tibetan areas. The poverty reduction effect of the NRCMS can be analyzed from two aspects:Firstly, the im-
provement in health leads to increased income, be-cause good health can promote labor productivity. Meanwhile, the increase in income will in turn im-prove the overall level of health. Secondly, the in-patient and outpatient compensation rate is raised year by year, which reduces the medical fees of farmers, and prevents them from falling back into poverty. 相似文献

对工匠精神的社会学考察认为,工匠精神并非适切于所有社会领域,所有领域的工匠精神弘扬与传承都需要自我约束和自我批评。工匠精神在其形态、观念与目标上呈现出较强的社会性实践指向,它与经济学意义上的优才制度之间存在着无可争辩的价值悖论。优才制度的土壤与气候不利于发挥普通民众的工匠精神,它极容易迫使一般民众隐身于精英群体聚光灯下的暗影之中,特别是在急功近利的柔性组织内是无法容纳工匠精神的。化解工匠精神与优才制度的悖论,现代职业教育或为此提供了一种行之有效的实践模式。从优才制度视角阐释工匠精神的存在逻辑及其悖论有益于当代社会弘扬工匠精神的实现路径。 相似文献
