王场油田是江汉盆地的一个重要油田,它是在盐岩流动的非构造应力与侧应力挤压共同作用下形成的盐背斜储油构造,具有形成早、陡、窄、高、断的特点,并为一同生构造。含油层系为下第三系潜江组,自上而下包括潜1~2、3~1、3~2、4~1、4~0、4~2、4~3七个油组。油藏类型为构造、岩性复合、低饱和、亲水、多盐的油藏。其油(气)富集规律如下:1、近邻蚌湖生油深凹陷,有优先捕获油(气)的条件。2、位于有利的岩相带,油层厚度较大,物性较好,为中低渗透油藏。3、王场背斜具“古高今高”的特点,为油(气)聚集和富集创造了良好条件。4、车挡同生断层封闭性好,油(气)主要沿断裂带附近富集。
Wangchang Oilfield is an important oilfield in Jianghan Basin. It is a salt anticline oil reservoir formed under the action of non-tectonic stress and lateral stress squeezing of rock salt flow. It has the characteristics of early, steep, narrow, high and broken Features and structure for a living together. The oil-bearing system is the Qianjiang Formation of the Lower Tertiary. From top to bottom, the oil-bearing formations include seven oil reservoirs 1 ~ 2,3 ~ 1,3 ~ 2,4 ~ 1,4 ~ 0,4 ~ 2,4 ~ 3. The reservoir types are structural, lithologic complex, low saturation, hydrophilic and multi-salt reservoirs. The oil (gas) enrichment rules are as follows: 1, near the lake deep oil deep depression, priority to capture the oil (gas) conditions. 2, located in the favorable lithofacies belt, the reservoir thickness is thick, good physical properties, as low permeability reservoir. 3, Wang anticline with “ancient high today,” the characteristics of oil (gas) accumulation and enrichment created a good condition. 4, the car with the same fault fault sealing, oil (gas) is mainly concentrated along the vicinity of the fault.
