在工程方面控制缝高对提高压裂效果至关重要,在勘探开发中对判断储层、认识储层和改造储层具有重要意义。为此,根据松辽盆地的沉积特征及影响人工压裂缝高因素多的特点,在勘探开发中运用井温缝高测试方法对松辽盆地中央凹陷区测试研究并分析。研究表明,该区域的沉积特征、地应力和施工参数对压裂缝高的影响是主要因素。通过理论分析和实践认识,对松辽盆地扶余油层南部人工裂缝高度有了明确认识,提出了控制缝高技术的研究方向。
It is very important to control the seam height in engineering to improve the fracturing effect. It is of great significance to judge the reservoir, recognize the reservoir and reform the reservoir in exploration and development. Therefore, based on the sedimentary characteristics of the Songliao Basin and the characteristics of many factors influencing the fracturing height in the Songliao Basin, the test of central temperature depression in Songliao Basin was studied and analyzed by using well temperature and seam height test in exploration and development. The research shows that the sedimentary characteristics, in-situ stress and construction parameters in this area have a major impact on the fracture height. Through theoretical analysis and practical understanding, we know the height of artificial fractures in the southern part of Fuyu oil layer in Songliao Basin and put forward the research direction of high-tech control seam.
