1大斜度井和水平井地层评价中的经验、问题和发展方向显示文摘大斜度井和水平井(HA/HZ)测井组合的选择原则主要是指导地质导向钻井。有时(HA/HZ)井所穿过的地层或油藏某部分没有垂直评价井,只能用HA/HZ测井数据评价常规有效厚度/总厚度比、孔隙度和含水饱和度。对同一地层,HA/HZ测井响应与垂直井响应存在很大差异。研究表明,由于视倾角误差,孔隙度值偏差可达6P.u.,含水饱和度误差超过50%,大斜度井中真地层厚度偏差达到200%~300%。垂直井的常规地层评价方法不太适用于HA/HZ井地层和流体性质评价。HA/HZ井与垂直井测井响应差异的主要原因是很多测井仪器是专为探测垂直井地层而设计的,因此在HA/HZ井中,必须对解释方案进行修改,这时需考虑井眼附近地层的几何形状;测量方位;地层各向异性对电阻率、声波和核测井响应的影响;异常侵入剖面;重力引起的仪器偏心以及井眼底部聚积的岩屑。虽然井眼成像测井能有效地测量大斜度井相对地层倾角,但当井斜超过80°时地层倾角的测量仍存在很多问题。中子和密度测井响应又相当程度地受岩屑的影响。这种井的测井难度很大,将差质量测井响应与因几何形状、各向异性以及井眼影响引起的异常测井响应区分开来显得相当重要。HA/HZ井用于地质导向的定性标准测井难以满足未来地层评价的要求。许多地方不能钻垂直评价井,因此利用大位移井信息评价地层很关键。作业公司和测井服务公司必须相互协作,共同解决HA/HZ井仪器响应和数据解释问题,开发出能定量描述HA/HZ井的新仪器。Quinn R Passey H Yin C M Rendeiro D E Fitz 唐宇 王昌学 2006测井技术2006,30,1:10
2Demand for hospital emergency departments:a conceptual understanding显示文摘BACKGROUND: Emergency departments (EDs) are critical to the management of acute illnessand injury, and the provision of health system access. However, EDs have become increasinglycongested due to increased demand, increased complexity of care and blocked access to ongoingcare (access block). Congestion has clinical and organisational implications. This paper aims todescribe the factors that appear to infl uence demand for ED services, and their interrelationships asthe basis for further research into the role of private hospital EDs.DATA SOURCES: Multiple databases (PubMed, ProQuest, Academic Search Elite and ScienceDirect) and relevant journals were searched using terms related to EDs and emergency health needs.Literature pertaining to emergency department utilisation worldwide was identified, and articlesselected for further examination on the basis of their relevance and signifi cance to ED demand.RESULTS: Factors influencing ED demand can be categorized into those describing thehealth needs of the patients, those predisposing a patient to seeking help, and those relating topolicy factors such as provision of services and insurance status. This paper describes the factorsinfl uencing ED presentations, and proposes a novel conceptual map of their interrelationship.CONCLUSION: This review has explored the factors contributing to the growing demand forED care, the infl uence these factors have on ED demand, and their interrelationships depicted in theconceptual model.Jun He Xiang-yu Hou Sam Toloo Jennifer R Patrick Gerry Fitz Gerald 2011World Journal of Emergency Medicine2011,2,4:2
