莺歌海盆地泥底辟带天然气成藏条件及勘探方向

GAS RESERVOIR AND EXPLORATION TARGETS OF MUD DIAPIR BELT, YINGGEHAI BASIN

莺歌海盆地泥底辟带存在浅层和中深层2套含气组合。剖析了浅层天然气的成藏条件后，认为应在已知气田周缘勘探类似地质条件的浅层构造圈内，以期形成中小气田成群连片联合开发。分析研究中探层含气组合后，认为其天然气成藏条件更为优越，勘探前景更诱人，提出了可望获得新的突破的几个构造为近期勘探目标。

Both shallow and deep gas plays are present in the mud diapir belt. Yinggehai Basin. The shallow gas play is studied, and it is considered that the shallower structural traps which have similar geological conditions with the known gas field should be explored surrounding the discovery in order to find a group of medium-small gas fields and to make joint development. The medium-deep gas plays is also studied, and it is considered that the medium-deep gas reservoirs are the more favorable and attractive exploration targets. Several prospects which are hopeful for new breakthroughs are pointed out.
