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.
