南阳凹陷张店油田油气勘探 3 0年 ,历经预探、详探、二次勘探等 3个阶段。预探阶段探明储量曾为 12 65× 10 4t,详探阶段大幅度下降到到 12 6× 10 4t ,原因主要是勘探早期二维地震测网较稀 ,圈闭不落实 ,加之探井太少 ,对油层特征认识不够深入。二次勘探阶段广泛采用三维地震和测井、钻井等方面的新技术 ,同时应用新理论、新方法开展地质综合研究 ,深化对地质规律的认识 ,不断有勘探新发现 ,探明储量有望再增长到 10 0 0× 10 4t。
Oil and gas exploration in Zhangdian Oilfield, Nanyang Depression For 30 years, it has undergone three stages of pre-exploration, detailed exploration and secondary exploration. The proven reserve in the pre-exploration stage was once 12 65 × 10 4 t, and the detailed exploration stage dropped sharply to 12 6 × 10 4 t. The main reason is that the early 2D seismic survey network is rather scarce, the trap is not implemented, and too few exploration wells , Understanding of the characteristics of the reservoir is not deep enough. In the second exploration stage, new technologies such as 3D seismic, well logging and drilling are widely used. At the same time, new theories and new methods are used to carry out comprehensive geology research, deepen understanding of geological laws, discover new discoveries and proved reserves are expected to increase To 10 0 × 10 4t.
