X油田开发中后期零散调整井经济界限及经济潜力井数研究

Research on the Scattered Adjustment Well Economic Limit and Potential Well Number in the Middle and Later Stages of X Oilfield Development

设定调整井不同钻井模式、方式下的钻井成本,综合考虑钻井投资、原油销售收入及采油操作成本等经济因素,建立以基准内部收益率为目标的经济评价模型,计算不同钻井方法所需的最低可采储量,进而建立目标油田的调整井经济界限图版。运用此方法,研究海上X油田开发中后期零散调整井的经济界限及经济潜力井数。

The drilling cost under different drilling modes and methods is set in adjustment wells in order to establish an economic evaluation model based on the benchmark internal rate of return,taking economic factors such as drilling investment,crude oil sales revenue and operation cost of oil production into account. Then,the minimum recoverable reserves is calculated for different drilling methods,and the economic limit chart for adjustment wells is set up in the target oilfields. The economic limit and potential well number of the scattered adjustment well in the middle and later stage of the development of offshore X oilfield are studied with this method.
