摘　　要：对于油田开发而言,油藏工程的重要性不言而喻,对其进行优化设计,可以提高油气采收率、降低生产成本、延长油田寿命周期,从而实现油田高效开采和生产。针对XH27块油田二次开发的需求,文章结合油藏地质特点和生产状况,采用综合理论和方法,对油藏工程进行了优化设计。首先,选择天然能量开发方式,并通过数值模拟验证了蒸汽吞吐(SAGD)技术的有效性;其次,根据油藏特征分层开发,确定了水平井整体替代直井的开发方案,并优化了水平井的设计参数;最后,通过采用多种方法确定了水平井的合理生产压差和部署位置。研究结果表明,采用二次开发方案能够有效提高油田采收率,具有良好的工程应用价值。The importance of reservoir engineering in oilfields development is self-evident,and its optimization design can increase oil and gas recovery rates,reduce production costs,extend the life cycle of oilfields,thereby achieving efficient oilfields exploitation and production.In response to the requirements of the secondary development of the XH27 block oilfield,this paper combines the geological characteristics and production conditions of the reservoir to carry out optimization design of reservoir engineering using comprehensive theories and methods.Firstly,the natural energy development method was selected,and the effectiveness of steam-assisted gravity drainage(SAGD)technology was verified through numerical simulation.Secondly,based on reservoir characteristics,a layered development plan was determined,with horizontal wells replacing vertical wells,and the design parameters of horizontal wells were optimized.Finally,various methods were employed to determine the reasonable production pressure differential and deployment locations of horizontal wells.The research results indicate that the secondary development scheme can effectively improve the oilfield recovery rate and has good engineering application value.
