汤原气田是佳木斯市主要供气气源，随着城市供气规模扩大，亟需加强气田开发力度。该气田位于吉祥屯三维工区内，工区构造复杂、断层发育，控制着储层与气水分布。通过井￣震紧密结合、地质建模等技术，开展气田精细构造描述与建模研究，完成多方位全三维断层精细解释，降低了构造误差，提高了构造图精度，为井位优化部署、气藏数值模拟提供了基础，初步实现气田有效开发，缓解了城市供气矛盾。

Tangyuan Gas Field is the main gas source for Kiamusze gas grid. At present, as the gas supply scale in city expands, gas supply is in a state of tension and it is in urgent need of gas field development. Tangyuan Gas Field is located in 3D seismic zone of Jixiang village. The structure of working area is complex and faults develop, which controls the distribution of reservoir and GWC (gas/water contact). By the technologies such as integrating well-logging and seismic, and geological modeling, we carry out fine structure interpretation and modeling research for gas field, and accomplish the multi-azimuth and full 3D fine interpretation of fault. Structural error is reduced and the accuracy of structural diagram is improved. This provides base for optimizing well deployment and numerical simulation of gas reservoir, preliminarily achieving the effective development of gas field and relieving the contradictions between gas supply and demand in Kiamusze City.
