【摘要】：为了进一步提高对潜山油藏的认识,对兴古潜山开展了监测工作,通过动态监测数据的对比分析,得到潜山油藏压力变化规律,确定合理的工作制度、油藏类型,判断地层连通情况及吸水能力,为该区块开发方案及措施方案的制定与调整提供了依据。本文的研究内容有:开展系统试井,通过监测静压、流压跟踪油藏压力变化;开展干扰试井,了解井间干扰状况;开展压力恢复测试,求取油藏储层孔隙特征参数;开展试注工作,通过分析研究注水指示曲线,落实储层吸水能力。通过分析地层的压力变化曲线来跟踪油藏的压力变化,在及时、准确的掌握油藏压力变化动态且明确了压力变化与产能的关系后,与系统试井相结合,目的在于合理调整自喷井的生产制度,保证自喷井的合理生产,维护油井的自喷能力;通过分析油井之间生产的干扰数据,证明井组之间和整个兴古潜山不同段内井间、段内井间的连通情况。通过比较分析前后两个年度的压力恢复测试结果,得到该区块渗透性、井周污染情况以及完井效果;通过分析启动压力、吸水指数等数据,落实兴古潜山的储层吸水能力和各项特性。
[Abstract]:In order to further improve the understanding of buried hill reservoir, the monitoring work of Xinggu buried hill reservoir is carried out. Through the comparison and analysis of dynamic monitoring data, the law of pressure change of buried hill reservoir is obtained, and a reasonable working system is determined. The reservoir type, the judgement of formation connectivity and water absorption ability provide the basis for the formulation and adjustment of the development plan and measure scheme of the block. The research contents of this paper are as follows: develop systematic well test and monitor static pressure. The flow pressure follows the change of reservoir pressure; Conducting interference well testing to understand the interwell interference situation; Carry out pressure recovery test to obtain reservoir pore characteristic parameters; Through the analysis and study of water injection indication curve, the reservoir water absorption ability can be implemented. The reservoir pressure change can be tracked by analyzing the formation pressure change curve, and the reservoir pressure change is in time. After accurately mastering the change of reservoir pressure and clarifying the relationship between pressure change and productivity, the purpose of combining with system well testing is to adjust the production system of self-blowout well reasonably and ensure the reasonable production of self-blowout well. Maintain the self-blowout capacity of the well; By analyzing the production interference data between wells, it is proved that the inter-well and inter-well connectivity between wells and between different sections of Xinggu buried hill is proved, and the results of pressure recovery test before and after two years are compared and analyzed. The permeability of the block, the pollution around the well and the completion effect are obtained. By analyzing the starting pressure, water absorption index and other data, the reservoir water absorption capacity and various characteristics of Xinggu buried hill are implemented.
