In view of the rheological property of the heavy oil in Bo-hai field, this paper deduces the multilateral wells'production model of Non-Newtonian Bingham fluid with equiangular transformation method. In view of the multilateral wells Bo-hai, the paper analyses the multilateral wells'capitalized cost composition, including pre-drilling engineering, drilling engineering, completion engineering and production engineering. It also constructs the multilateral wells'economic benefit models basing on net present value, inner rate of return and payback period.

针对我国渤海油田稠油的流变特性，运用保角变换方法，推导了非牛顿Bingham流体的分支水平井产能模型；针对渤海油田的分支井，从钻前工程、钻井工程、完井工程、采油工程等方面对分支井的投资成本费用构成进行了具体分析；最后以净现值、内部收益率、投资回收期经济评价指标为基础，建立了海上分支井经济效益模型，并根据所建模型应用VB。

And tower water supply drainage work is compared with in general multilayer building and low tier of buildings water supply drainage work , fundamental theory and reckoning are identical in the field of some , tier of numbers are many because of the tower , the building altitude is big , the building function is broad , building structure is complicated but, what be accepted the external world condition restricting waits, tower water supply drainage work is listed in disregarding being to be still extent on technology depth,have exceeded low tier of buildings water supply drainage work category, The number having the following few characteristics tower water supply draining off equipment is many and, instant the source of water that the rate of flow giving a water yield and draining away water depends on , rational water supply of economy sewerage form and , breathable appropriate treatment draining off pipeline problem and, to ensure that water supply safety is reliable , the administration draining away water unobstructed and defending is convenient.

高层建筑给水排水工程与一般多层建筑和低层建筑给水排水工程相比，基本理论和计算方法在某些方面是相同的，但因高层建筑层数多、建筑高度大、建筑功能广、建筑结构复杂，以及所受外界条件的限制等，高层建筑给水排水工程无论是在技术深度上，还是广度上，都超过了低层建筑物的给水排水工程的范畴，并且有以下一些特点高层建筑给水排水设备的使用人数多，瞬时的给水量和排水流量靠的水源，以及经济合理的给水排水系统形式，并妥善处理排水管道的通气问题，以保证供水安全可靠、排水通畅和维护管理方便。

Its economic internal rate of return is 13.41%, larger than its social discount rate 12%, therefore, the project is economically rational.

该工程的经济内部收益率为13.41%，大于社会贴现率12%，所以该工程在经济上是合理的。

固海扬水工程近30a来，为宁夏中部干旱带的社会及经济发展作出了巨大贡献，但是由于长期以来经费短缺，工程设施得不到及时维修，老化日益加剧，为了对宁夏固海扬水工程设施老化状况作出定量的科学评价，通过长期实践并结合数学理论知识，建立了固海扬水渠道工程老化现状评价的数学模型，为固海扬水工程进一步改造和规划提供科学决策的依据。

In order to facilitate the feasibility study of large-scale public construction, this research applies the Project Management Body of Knowledge developed by the Project Management Institute, along with the Taipei City Government's experiences, trying to conduct the management model of public construction feasibility study. This research concerns five primary processes including initialing, planning, purchasing, contract-administrating, closing. Moreover, it clearly portrays the essentials in feasibility study and organizes relevant working forms, in order to improve the public project benefit and guarantee that the public construction can be executed successfully.
