“江苏地区”概以鲁东隆起之南,郯庐断裂系之东、江南古隆以北,东至南部黄海海岸范畴之内。工区南部基岩露头发育,工作程度甚高,西部、北部有零星露头分布,余者为几十至300多米厚的第四系覆盖,谓之“苏北坳陷区”。覆盖区内,自五六年特别是五八年以来开展了大规模的综合物探、钻探等石油地质工作,目前已进入石油普查勘探和油气田勘探开发并举的会战局面。
The “Jiangsu Province” consists of the south of the Ludong uplift, the east of the Tanlu Fault System, the north of the Gulong Jiangnan, the Yellow Sea coast of the east to the south. The outcrop of bedrock in the southern part of the work area is developed and has a very high degree of work. There are sporadic outcrops in the west and north and the remaining Quaternary covers of several tens to 300 meters thick, which is called the “Northern Jiangsu Depression Area.” Within the covered area, a large-scale comprehensive geophysical exploration and drilling and other petroleum geology work has been carried out since five or six years, especially in five or eight years. At present, it has entered the battle of petroleum census exploration and oil and gas exploration and development.
