摘要
莺－琼盆地快速沉降和沉积的地质背景，导致盆地具高温高压的特征。高温高压环境是盆地内油气生成、运移和聚集的重要地质因素，高温高压油气水以间歇式混相运移方式进行。当“深部高温高压包”增压到接近或超过上覆地层负荷压力时，地压流体（油气水）突发性地沿①号大断层上升，并在断层附近聚集成藏，形成了崖13－1气田。
Quick sedimentation of Yinggehai-Qiongdongnan basin lead to its high temperatured and geopressured characteristics. Hot and geopressured environment is an important factor of hydrocarbon generation, migration and accumulation in the basin. Hydrocarbon and water migrated intermittenly in a miscible form. When the 'deep high pressure and temperature reservoir' pressurized to about/above the overburden pressure, geopressured fluids (oil,gas and water) abruptly moved upward along Fault No. 1 and accumulated to form reservoirs near the'fault. Hence,YA 13-1 gas field was formed.
