摘要
砂砾岩油藏具有渗透率低、非均质严重、连通性复杂等特点,通过对干扰试井适用性的分析,认为对于砂砾岩油藏,尤其是注水开发的砂砾岩油藏,利用干扰试井能够有效判断井间连通性,指导油田开发部署。结合胜利油田砂砾岩油藏开发实际,提出了砂砾岩油藏群井干扰试井的优化方案,现场应用取得了良好的效果,明确了干扰试井在砂砾岩油藏认识中的有效性。
Glutenite reservoirs have the characteristics of low permeability,severe heterogeneity and complicated communication.By the analysis of the adaptability for interference test,it was thought that in glutenite reservoir,especially in waterflooding glutenite reservoir,the interwell communication could be diagnosed by interference test,which would provide valuable references for field development plan.Furthermore,some optimized testing suggestions were put forward,which obtained a good effect in field application.The adaptability of interference test in glutenite reservoir was conformed further.
