查询词典 equiangular transformation

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。
