陆梁油田陆9井区由于受低幅度构造影响,成藏过程中单层(砂层厚度5～10m)未被充满,造成所有的油井同一层内形成上油下水的分布特点。油藏开发初期采用反九点面积注水井网开发,目前已进入中高含水期,采出程度为20%左右,为了挖掘剩余油潜力,应用油藏数值模拟结合实钻穿层井验证方法对薄层底水油藏水驱油规律进行了研究。研究结果表明,陆9井区薄层底水油藏水驱特征为底部水淹型,剩余油呈船底形状分布规律。 Due to the low amplitude structure, the Lu 9 well in Luliang Oilfield is not filled with single layer (sand thickness 5 ~ 10m) in the process of reservoir formation, resulting in the distribution of oil underwaters in the same layer of all oil wells. In the early stage of reservoir development, an anti-nine-point water injection well pattern was developed. At present, it has entered the middle-high water cut period and the recovery rate is about 20%. In order to excavate the residual oil potential, reservoir numerical simulation and drilling verification The law of water flooding in bottom water reservoir was studied. The results show that the water flooding characteristics of the thin bottom water reservoir in Lu 9 well are the bottom flooding type and the remaining oil is in the shape of bottom shape.
