摘要
苏1井位于海拉尔盆地乌尔逊断陷北部苏仁诺尔构造带苏六—9号断背斜中部，油层分布在南屯组，录井综合解释油层23层，厚37．6m。完钻测井后裸眼测试3个井段，其中1个井段获油流，水力压裂改造目标为日产原油10t。经过分析、研究，挑选11层油层厚21．6m进行水力压裂改造。压裂后获日产原油20．7t。效果分析：该井位于生油断陷，油源充足，构造完整，有利油气聚集。裸眼测试成果便于确定压裂后产油目标、精选被压裂油层、求取合理压裂参数。
Su 1 well is located in the middle of Su 6-9 fault anticline which is in the Surennuoer structure in North of Wuerxun aulacogen in Hailaer Basin. the producing zone located in Nantun group. Logging interpretation result is that there are 23 oil layers to thickness of 37. 6m. After Drilling, 3 layers were tested,one of them got industry production. the aim producing rate of hydraulic fracturing is 10t/d. According to analysing, 11 layers to a thickness of 21. 6m were selected to hydraulic fracture. After fracturing,the production rate is 20. 7t/d. The evaluation is that this well is located in the oil source bed,the oil source is sufficient,the structure is complete and suitable for oil accumulation. Open hole testing is suitable for determining the producing rate after fracturing,selecting the fracture layers and getting the reasonable fracturing parameter.
