海上稠油油藏蒸汽吞吐注采参数正交优化设计
Orthogonal optimization design of injection and production parameters in cyclic steam stimulation in offshore heavy oil reservoirs
摘要
Abstract
Based on a heavy oil reservoir in Bohai oilfield,a numerical simulation model of cyclic steam stimulation is built based on the characteristics of offshore oilfields.The orthogonal experimental design and numerical simulation are used to optimize the steam injection intensity,steam injection rate,bottom hole steam quality,steam temperature,soaking time and liquid producing capacity.The visual analysis and variance analysis are used to analyze the results.The results show the optimized injection and production parameters are steam strength 20 t/m,steam injection rate 250 m3/d,the bottom steam quality 0.5,steam injection temperature 340 ℃,soaking time 5d,and the production rate 200 m3/d.The influence factors on the effect of steam soaking decreased gradually in the following order:steam strength,the bottom steam quality,the production rate,steam injection rate,steam injection temperature,and soaking time.The results can provide theoretical guidance for injection and production parameters optimization of steam huff and puff in offshore heavy oil reservoirs.关键词
