肇源地区扶余油层油水层识别评价方法研究与应用

Study on application of oil and water zones identification for Fuyu reservoirs in Zhaoyuan area

2004年以前,对肇源地区扶余油层的共同认识基本上不产水,录井解释均为纯油层和干层,没有解释水层的,所应用的录井资料也比较单一。在水性识别方面对资料的认识及解释标准均为空白。2004年试油井大量产水,按原来的方法解释,结果符合率急剧下降到77.0%。为此,对该区扶余油层油水关系重新认识,建立新的油水关系解释标准和图版,填补水性识别的空白,通过生产实际应用,新方法录井解释符合率提高到91.2%。

Before 2004, recognition on Fuyu reservoirs in Zhaoyuan area was no water produced, logging interpretation was pure oil zones and dry zones without water zones. Logging data used was single. There was no recognition or interpretation standard for water identification. In 2004, oil test well produced a large amount of water. Using the original interpretation method, the conformity percentage decreased to 77.0%. This paper introduces the re-recognition on oil/water relation of Fuyu reservoirs, constructs a new interpretation standard and chart and fill the blank of water identification. Application shows that the interpretation conformity percentage increases to 91.2%.
