The Study On Overall Evaluation And Technical Development Strategies For Super Heavy Oil Resverior Of Block Du229

Du229 is the most typical block for heavy oil recovery with cyclic steam stimulation technique. After seven-year development,the technologies of production and relative construction is more and more perfect.Based on the resverior ananlysis ,and combined with dynamic and static datas , this paper give a systemic study on the variedly main resverior parameter factors that influence the development effect on super heavy oil,and according to this set up the calculation formula and Du229 block standard of the resverior evaluation,making a integrated evaluation for the oil layer of this block.With analysing the production characteristic and summarizing the development rule,the paper analysis the development influencial factors and working on the present production situation and oil exploitation status, estimating the whole production result,analysing the remaining oil potential,give a basis for the later technical strategies.Besides, analysising the contradiction of different cyclic steam stimulation phase, combining the practical production contradiction,the accordingly feasible disposal measure is put forward.In addition, according to the present production situation and the factors that influence the development such as the high exploitation exention,increasing deficit of stratum,augmenting interbedded contradiction and so on,it also deals with the the development technique research of improving high order effect.Becanse of these technology application,the development effect of late period cyclic steam stimulation is improved,with better economic benefit.At the same time,the exploration for technical strategies also offer the base for the realization of the late period high efficiency development block and enhancing oil recovery in Du 229.This paper is a comprehensive summarization on super heavy oil with steam huff and puff technique.
