复杂断块油藏具有非均质严重、连通性复杂等特点,利用干扰试井能够有效判断井间断层是否存在及其封堵性,确定断层的伸长度,认识油藏平面上的非均质性,研究地层的各向异性,计算井间的储层物性参数等。干扰试井解释结果可以为复杂断块油藏及储层变化大的油藏部署开发井网、完善注采关系,实施高效注水开发提供可靠的科学依据。
The complex fault block reservoirs are characterized by serious heterogeneity and complex connectivity. By using the interference well test, it is possible to effectively determine the presence and the sealing of the fault between the well and determine the fault extension, and to recognize the heterogeneity in the reservoir plane To study the anisotropy of the strata and calculate the physical properties of the reservoir between the wells. The interpretation of interference well test can provide a reliable scientific basis for deploying and developing well patterns for complex fault block reservoirs and reservoirs with large reservoir variations, improving the relationship between injection and production, and implementing efficient water injection development.
