摘要:

断控缝洞型油藏非均质性极强,油藏开发特征显示出井间连通关系的多样性和复杂性,厘清断裂和岩溶对储集体发育的影响,有利于油藏连通性分析及注采措施调整。以塔河油田托甫台地区T单元为例,综合地震解释结果、上覆水系特征以及生产动态响应规律,系统分析储集体的发育特征。储集体发育主要受控于断裂和地表水系,岩溶作用强度差异导致储集体发育特征不同,使开发井表现出不同的井间连通关系和生产特征。基于动静态资料分析,建立了适用于断控缝洞型油藏的井间连通模式,为后续措施调整提供依据。

Abstract:

Fault-controlled fractured-vuggy reservoirs are extremely heterogeneous and exhibit the diversity and complexity in inter-well connectivity. Clarifying the influence of faults and karsts on reservoirs is conducive to reservoir connectivity analysis and injection-production strategy adjustment. Taking Unit T in the Tuofutai area of Tahe oilfield as an example, the development characteristics of reservoirs were systematically analyzed based on the results of seismic interpretation and the analysis of overlying water system and production performance responses. It was clarified that the reservoir development is mainly controlled by faults and surface water systems. The difference in karstification intensity leads to different characteristics of the reservoirs, which makes development wells show different production behaviors and inter-well connectivities. Based on the analysis of dynamic and static data, an inter-well connectivity model suitable for fault-controlled fractured-vuggy reservoirs was established, which can provide a basis for the adjustment of subsequent treatments.

Key words: Tahe oilfield, Tuofutai area, fault-controlled fractured-vuggy reservoir, karstification, main controlling factor, reservoir distribution, connectivity model
