王官屯油田地处河北省沧县王官屯乡境内,区域构造位置为黄骅坳陷南区孔店构造带的西南端,处于孔东断裂带两侧。根据钻录井特征、地球物理响应特征,结合区域地层对比,将王官屯油田官142地区中生界地层划分为中下三叠统、中下侏罗统、上侏罗统-下白垩统三套旋回。通过对该区地层特征的分析,认为中下三叠统以棕红、紫红色粉细砂岩和泥岩互层为主;中下侏罗统下部主要为暗色泥岩夹砂岩,上部为一套巨厚砂砾岩,并作为中生界油藏主要储集层;上侏罗统-下白垩统发育紫红色砂岩及安山岩。通过分析各时期的构造运动特征,认为印支运动以整体抬升为主,发育了三叠系地层;燕山早期以走滑和挤压为主,盆地规模较小,发育中下侏罗统的河湖相沉积;燕山中期火山活动强烈,发育火山物质为主的晚侏罗世-早白垩世地层;燕山晚期该区整体抬升遭受剥蚀,缺失上白垩统地层。而喜山时期的升降运动对中生界油气成藏具有重要意义。 The Wangguantun Oilfield is located in Wangguantun Township, Cangxian County, Hebei Province. Its regional tectonic location is the southwestern end of the Kongdian structural zone in the southern part of the Huanghua Depression, which is located on both sides of the Kongdong fault zone. According to the characteristics of drilling well and geophysical response and the comparison of regional strata, the Mesozoic strata of Guan 142 area in Wangguantun oilfield are divided into three types: Middle-Lower Triassic, Middle-Lower Jurassic, Upper Jurassic-Lower Cretaceous Swing. Based on the analysis of stratigraphic features in this area, it is believed that the Middle-Lower Triassic is dominated by interbeds of reddish-purple and purple-red fine sandstone and mudstone; the lower part of Middle-Jurassic is mainly dark mudstone sandstone with a thick Gritstone, and as the main reservoir of the Mesozoic reservoir. The Upper Jurassic-Lower Cretaceous developed purplish red sandstone and andesite. By analyzing the tectonic movement characteristics of each period, it is considered that the Indosinian movement was dominated by the whole uplift and developed the Triassic strata. In the early Yanshanian, the strike-slip and crustal were dominant, and the basin was small in scale, with middle and lower Jurassic rivers Lacustrine facies; Late Yanshan volcanic activity, the development of volcano-dominated Late Jurassic - Early Cretaceous strata; the late Yanshan uplift suffered erosion, the absence of Upper Cretaceous strata. The Himalayan uplift movement of the Mesozoic hydrocarbon accumulation is of great significance.
