本文在调剖理论的基础上,以西达里亚区块DK15井为例,分析了决定水窜的主要因素,讨论了调剖技术对DK15井的可行性,认为:(1)决定DK15井组水窜的主要因素是储层的强非均质性;(2)剩余油丰富、连通性好、井间对应性好、调剖时机成熟为DK15井调剖提供了技术可行性依据;(3)现有调剖剂满足油藏条件、工艺安全性高为调剖现场实施扫清了最后屏障。所以,调剖技术在塔河碎屑岩边水油藏注水开发中具有广泛的应用前景。
Based on the profile control theory, taking the DK15 well in West Daria region as an example, the main factors that determine water channeling are analyzed. The feasibility of profile control technology for DK15 well is discussed. It is considered that: (1) The main factor of water channeling is the strong heterogeneity of the reservoir; (2) the remaining oil is rich, the connectivity is good, the correspondence between the wells is good, and the timing of profile control is ripe to provide the technical feasibility for the profile control of well DK15; ) Existing profile control agent to meet the reservoir conditions, high process safety for the implementation of profile control cleared the final barrier. Therefore, the profile control technology has a wide range of application prospects in the waterflooding development of Tahe detrital reservoir.
