黄骅坳陷天然气资源潜力与勘探开发对策

黄骅坳陷的天然气勘探始终是与石油勘探同时进行的。新一轮资源评价结果表明:本区天然气资源丰富,探明程度较低,剩余资源潜力较大;这些资源主要分布在板桥、歧口凹陷大于3 500 m的深层。同时,本区上古生界煤系地层分布范围也很广,煤成气资源也十分丰富。因此,为实现大港油田天然气生产的良性循环,应坚持科技创新和油气并举的原则,加快对黄骅坳陷天然气新领域的勘探步伐,加快气田(藏)的高效开发和老区的滚动挖潜。

NATURAL GAS RESOURCE POTENTIAL AND THE STRATEGY OF EXPLORATION AND DEVELOPMENT IN HUANGHUA DEPRESSION

Natural gas is always explored along with oil exploration in Huanghua depression. The third resource evaluation indicated that natural gas resources in the depression arc abundance. Though the proven reserve is low, the residue potential is large. Those resources are mainly distributed in Banqiao and Qikou sags find the depth of reservoirs is more than 3 500 m. At the same time, coal bearing series strata in upper Paleozoic distributes within all basins, so coal-genetic gas is also abound. In order to realize that natural gas production will he in good condition in Dagang oilfield, new natural gas fields must be fast explored, by taking technology initiatives, using strategy of simultaneous exploration for gas and oil. speeding up high effective development of gas fields and rolling exploration within developed fields.
