摘要
华庆地区位于陕西省吴旗县白豹乡和甘肃省华池县乔河乡境内,面积约1670km2,属黄土塬地貌。白153～白155井区位于华庆油田东部,构造上位于鄂尔多斯盆地陕北斜坡带的南部,总体为一西倾单斜,倾角不足1°。本区自上而下钻遇地层有第四系,第三系,下白垩统志丹组,侏罗系安定组、直罗组、延安组和富县组,三叠系延长组。主要含油层系为三叠系延长组长4+5、长6、长8等,其中长6油藏为目前华庆油田主要开采的产油层位之一。本文从沉积特征,岩矿特征,物性特征,非均质特征等方面综合研究了本区的储层特征。
HuaQing area is located in the WuQiXian shanxi province BaiBao township and gansu province within the territory of HuaChiXian QiaoHe township, an area of about 1 670 square kilometers, the loess tableland landform. White 153-white 155 wellblock is located in the east HuaQing oilfield, located in the ordos basin structural shanbei slope belt south, overall is a west pour monoclinic, angle less than 1 ~. The top-down drill strata have 4 de- partment, tertiary, lower cretaceous ZhiDan group, Jurassic stable group, straight ROM group, yanan group and rich county group, trias extended group. The main oil-bearing series for trias extended chang4 ＋ 5, 6, 8 and etc, which is chang 6 reservoir as the main production HuaQing oilfield of oil producing one of the oilfield . This paper from the sedimentary char- acteristics, rock ore characteristics, physical property characteristics, heterogeneous features a comprehensive study of the reservoir characteristics.
