Relationship Between Steam Soaking Effect And Influencing Factors Of Heavy Oil In L Oilfield,Bohai

As a kind of thermal recovery,steam huff and puff is widely used in land oilfield,a lot of experience has been accumulated.Now the research work of steam huff and puff in offshore oilfield is still in the initial stage,production practice experience is very scarce,Production practice of offshore Oilfield is few,the relevant research is still insufficient.Firstly,the influence factors and evaluation indexes are collected through extensive literature research in this paper.I eliminate the influence factors and indexes by means of logical analysis.And I eliminate the influencing factors and indicators through the logic analysis method.And I choose the evaluation index according to the field practical conditions.Then the single factor and multilevel numerical simulation scheme is formulated according to the screening results.I use CMG to get the results of univariate and multilevel numerical simulation in CMG,the grey correlation analysis method was used to calculate the degree of association,According to the size of the correlation degree,the correlation strength ranking was carried out.I choose a number of factors that are associated with higher relevance.The numerical simulation calculation of the full Permutation and combination scheme of the optimization factors is made.I find the best combination of the program through the comparison of the final product.Finally,it is proved that the optimal oil production scheme is the best one according to the numerical simulation results.
