摘要
渤海湾地区曹妃甸油田的大部分水平井投产后就出现高产水现象,到目前为止,该地区有大量水平井己处于中、高含水期,高产水己成为降低该区块产量的主要原因。如何采取合适的措施降低产水量和提高产油量成为大家关心的问题,为了解决这一问题,相关学者引入ICD工具来控制水的产量,并采用数值模拟的办法模拟ICD在井下工作状况,并实例对比了采取ICD完井和不采取ICD完井这两种情况下水平井产水情况。模拟计算结果表明:沿水平段地层渗透率的不均质性是造成水平井段局部水锥进的主要原因;优化完井方式能够延迟水平井段进水;ICD适用于类似曹妃甸油田这种薄油层、强底水驱油田的控水措施。
Most of the horizontal wells in the CFD oilfield in Bohai basin suffered the high rate of water production. The high rate of water production has became the main reason of lowering the oil production in this block. This paper take the numerical simulation on the water coning problem, and get the results as following：The permeability anisotropy along the horizontal section is the key reason for water coning happened to the wells in the bottom wa- ter drive reservoir. Optimizing the well completion can delay the water coning, and install the ICD tools on proper position can equalizing the inflow rate, by this way, the water pro- duction can be reduced obviously. ICD can be applied to the thin oil layer and strong bottomwater reservoirs which have the same characteristics of CFD oilfield.
