Study On The Evaluation Method Of The Effect Of Steam Stimulation

There are a lot of heavy oil resources in our country, and heavy oil is the important component part of production in our country, but heavy oil recovery is a very complete project. Though home and abroad have researched heavy oil recovery many years, steam stimulation is still the uppermost method of heavy oil recovery. The operations of steam stimulation are various, and many indexes should be considered in production process. So we must build a suit of evaluation system to development indexes, through it to direct production and achieve better development effect. This paper establishes the evaluation system which regards transient oil-gas ratio, water recovery, injected gas-oil ratio as the main indexes, and gives the computing method of limiting oil-gas ratio, evaluates and computes in view of the Du84 block of LiaoHe Oilfield, the result indicates the evaluation method is reliable, and has definite guide meaning.
