    摘要:

    油井多层合采是一种常见的油藏开发生产方式,但是多层合采常会产生层间干扰现象,降低原油采收率。针对这一问题,提出了基于干扰系数进行分注分采的调整方法。以SZ油田多层合采层间矛盾突出从而进行分采调整为实例,针对实际生产矛盾与小层地质特征,结合五个不同的干扰系数,提出了三十种分层开采的调整方案。定含水率对比不同方案的预测结果,考虑到海上油田平台寿命有限,同时采用了定年限的对比优选方法。研究结果表明:分层开采方式使生产得以改善,定年限和定含水率方法各自最优的调整方案采出程度分别提高了7.79%与2.63%。为非均质多层系油层的分层开采提供了理论依据。

    Abstract:

    Commingling production is a usual way in the development of oil reservoirs, and interference phenomenon generated through the process reduces the oil recovery.To solve this problem, the adjustment method of slicing method is introduced based on the interference coefficient. Taking slicing production adjustment of SZ Oilfield with serious differences of development among different layers as an example, considering the field problems and geological characters, and with five different given interference coefficients, thirty adjustment projects of slicing production were made using numerical simulation method. The results when water rate was 98% were compared, and because of the limited life of the platform, the results of 10 forecast years were also contrasted. The study shows that: the oil recovery rate are increased by 7.79% (10 forecast years) and 2.63% (water rate 98%) respectively; therefore, the method of slicing production is beneficial to the production. The research result is helpful theoretically for the slicing production of the layered oilfields with great heterogeneity.
