摘要
结合油田实际,举3例分析了卡片曲线的特征应用。①在测试井段大、小层多,且电测解释为干层、水层、可疑层、薄油层等,利用卡片曲线特征指导压裂选层。②据卫321井卡片曲线特征,找出因电缆桥塞密封不好导致上、下两层审通。③改变测试管柱组合,据管柱漏失卡片曲线特征,搞准产出、漏失量。实践证明具有实用价值和经济意义。
Combined with oilfield practice, this paper presents three examples to analyse the application of curve characteristics of DST charts (1)For a long testing interval containing several small layers which were interpreted by electric logging as dry zones,water zones,questionable zones and thin oil zones, the curve characteristics of DST charts can be used to instruct zone selection for fracturing (2)On the basis of the curve characteristics of well Wei 321 DST chart, it was found the cross flow between upper zone and lower zone, which was caused by bad seal of wireline bridge plug (3)Adjust the composition of DST string. According to the curve characteristics of the charts from leaked strings, try to get accurate amount of production and leakage. Field practice proved that above mentiond applications have their practical value and economic significance.
