低层大气烃类检测预测南黄海盆地油气远景

HYDROCARBON TEST IN LOWER-LAYER ATMOSPHERE TO PREDICT HYDROCARBON POTENTIAL OF SOUTH YELLOW SEA BASIN

为了预测南黄海盆地油气远景,利用最新采集的383个站位的低层大气烃类检测数据进行评价。烃类检测结果为:高值甲烷异常区主要分布在南黄海北部坳陷西南,次高值甲烷异常区主要分布在中部隆起带西部和南部坳陷中部,而南北向带状分布的甲烷异常带位于南黄海的东部。结合南黄海盆地航磁异常和部分浅地层剖面资料,认为中部隆起带东侧及紧邻的北部坳陷西南具有较好的油气远景。

In order to predict the hydrocarbon potential used to evaluate its potential. Hydrocarbon test results the highest methane anomalous area is located in the sou of South Yellow Sea basin, hydrocarbon tests are of 383 lower-layer atmosphere samples show that thwest of northern depression in the South Yellow Sea; the second highest area is located in the west of central uplift and in the middle of southern depression; and methane anomalous area going banded in S-N direction is located in the east of the South Yellow Sea. On the basis of integrated studies of aero magnetic anomalies and some subbottom profiles, it is inferred that the east of central uplift and its adjacent northern depression probably have good hydrocarbon potential.
