Abstract

There exists controversy about the origins of reservoir overpressure in kelasu tectonic zone of kuqa depression . Based on it, the distribution and the evolution characteristics of reservoir pressure were analysed, the contribution of the tectonic compression stress to residual pressure was evaluated, and the overpressured causes of reservoir were discussed. The research results indicated that the tectonic compression stress is important factor for the overpressure of reservoir, and the contribution of the tectonic compression stress to residual pressure is different in different area of kelasu tectonic zone, and the contribution is increasing from west area to east area. Hydrocarbon injection also play an imorant part in overpressure of reservoir. The hydrocarbon injection can lead to the increasing of porefluid pressure. Along with the hydrocarbon injection, the ratio of tectonic compression transforming to porefluid pressure is increasing. In all, tectonic compression stress and the hydrocarbon injection are the main causes of reservoir overpressure, and in different area the main cause may be different.
