产量递减油田稀油产量预测综合新方法研究

Study on New Oil Production Prediction Method of Thin Oil in Production Declining Oilfield

我国大部分油田产油品质大部分为稀油,随着资源量的减少,新的勘探区块资源量的接替量不足,大部分油田区块进入产量递减阶段,资源关系到国家命脉,因此,对现有油田区块的稀油产量预测就至关重要。通过Arps递减法和产量构成法两种方法对油田区块稀油产量进行预测,以了解油田的进一步发展状况,为决策者提供重要依据。

At present, oil produced by most of our oil-producing oilfields is thin oil. With the decrease of the amount of resources, resource of new exploration blocks is not enough to replace. Most oilfields enter into the stage of production decline. Resources relate to national lifeline. Therefore, the thin oil production prediction of present oilfields is crucial. In this paper, the thin oil production of present oilfields was predicted by Arps decline method and production composition method, which can provide an important basis for further development of oilfields.
