摘要： 海上水驱稠油油田注采井距大、储量动用程度低，为提高油田开发效果，需要对基础井网进行调整。基于渤海地区实际HD油田情况和典型井网调整方式，利用渗流力学经典理论，建立基于反九点基础井网整体加密水平井进行注采井网调整的渗流模型，通过计算注采单元渗流场变化来分析不同条件下储量动用规律；利用建立的注采井网储量动用效果评价方法，优选出满足油田开发要求的加密水平井长度。研究表明：建立的组合井网储量动用评价方法结合油田实际可以得到加密水平井最佳长度为原井网井距的0.75倍。该成果可作为渤海地区及类似油藏进行注采井网调整的技术借鉴。

Abstract: Offshore waterflooding heavy oil fields have large injection-production well spacing and low reserve producing. In order to improve the effect of oilfield development,the basic well pattern needs to be adjusted. Based on the actual HD oil field conditions and typical well pattern adjustment methods in Bohai Sea,the classic theory of seepage mechanics was used to establish a seepage model based on integrally infilled horizontal wells with inverse nine-point basic well pattern for injection-production well pattern adjustment,and the reserve producing law under different conditions was analyzed by calculating the seepage field changes of injection-production unit. The established reserve producing effect evaluation method of injection-production well pattern was used to optimize the length of the infilled horizontal wells that meets the requirements of oilfield development. The results show that the optimal length of infilled horizontal wells is 0.75 times of the original well pattern spacing by combining the actual situation of the oilfield with the reserve producing evaluation method of combined well pattern. The research result can be used as a technical reference for injection-production well pattern adjustment in Bohai Sea and similar reservoirs.

Key words: seepage model, reserve producing law, infilled horizontal wells, well pattern adjustment, adjustment strategy, offshore oilfield
