摘要

本文介绍了伊尔库茨克地区油田油气勘探的经验。所研究设施的地质特征决定了一种切实可行的方法和紧凑而有效的技术解决方案的使用,这些解决方案以后可以成功地应用于具有类似地质的大量油田。本文重点介绍了利用“井底关井”技术,在套管井中开发和测试井目标目标的优化工作。这种安排确保了目标对象开发工作的有效实施,并允许高质量的井底压力动态记录。该工程解决方案可以在相对较短的时间内对目标井段进行全周期的流体动力学研究(试井)。管组的使用大大减少了井筒存储时间,并可以可靠地获得表征储层性质和所研究储层结构的详细数据。本文介绍了井底关井的水动力研究技术。本文论述了高产、流动设施的研究问题,通过具体实例,详细分析了技术特点、解释方案、可能出现的复杂情况和优化措施。考虑了在各种地质和技术条件下复制技术的可能性。

Application Rationale of Well Flow Test Complex Modules Covering Well Shut-in at the Bottomhole in terms of Eastern Siberia Carbonate Reservoirs Study
The paper presents the experience of oil and gas exploration in the fields of the Irkutsk region. The geological features of the studied facilities dictate a practical approach and the use of compact and efficient technological solutions that can later be successfully applied to a large number of fields with similar geology. The paper highlighted an optimized complex of works on the development and testing of wells target objects in a cased wellbore, using the technology of "the well shut-off at the bottomhole". This arrangement ensures the effective implementation of work on the development of target objects and allows for high-quality registration of the bottomhole pressure dynamics. This engineering solution allows to perform a full cycle of hydrodynamical studies of well (well test) for a target interval in a relatively short time. The use of a tube bank significantly reduces the wellbore storage eand allows to obtain detailed data reliably characterizing reservoir properties and the structure of the reservoir under study. The article describes the technology of hydrodynamic studies, with the well shut-off at the bottomhole. The article deals with the research problems of highly productive, flowing facilities, with a concrete example and a detailed analysis of technological features, interpretation options, possible complications and measures for optimization. The possibility of replicating technology in various geological and technical conditions is considered.
