中带西段位于东营凹陷中央背斜带西端,其西北为利津洼陷,东南为牛庄洼陷。区内已发现郝家油田、史南油田、现河庄油田等油田在沙二~(10)层位均见不同程度的油气显示,95口井在该层位获得油流,截止到2007年,已在沙二~(10)层位上报探明含油面积16.6km2,储量1220万吨,展示了该区具有较大的勘探潜力。但由于储层横向变化很快,砂体之间的对比难度很大,砂体成因类型及其展布规律难以确定,油气聚集规律也有待进一步认识。
The western section of the middle belt is located at the western end of the central anticline in the Dongying depression, with Lijin depression in the northwest and Niuzhuang depression in the southeast. Oil fields in the oil fields of Haojia Oilfield, Shi Nan Oilfield and Xianhezhuang Oilfield have been found to have different degrees of oil and gas content in the sand layers (10) and 95 wells have obtained oil flow in this layer, and as of 2007 , A proven oil-bearing area of 16.6km2 and a reserve of 12.2 million tons have been reported on the second to the 10th strata of Shahe, which shows that the area has great exploration potential. However, due to the rapid horizontal change of reservoir, the contrast between sand bodies is very difficult, the type of sand body and its distribution law are difficult to determine, and the law of hydrocarbon accumulation needs to be further recognized.
