鄂尔多斯盆地延长组油层压裂配套改造技术

Fracture and Matching Reform Technology for Yanchang Oil Layer in Eerduosi Basin.

以鄂尔多斯盆地延长组油层地质特征、储层分类研究为基础 ,通过大量现场应用 ,总结出适合各类延长组油层的射孔技术、钻具结构、支撑剂、压裂液及配套的压裂施工参数 ,并详细介绍了几种能不同程度提高单井产能、防止大量吐砂、有效抑制底水的压裂技术及其应用效果。

Based on the geological feature and formation's classification research study for Yanchang layer in Eerduosi basin, with amounts of field applications, the paper sums up the perforation technique, drill stem structure, fracturing proppant, fracture fluid and the matching fracture operation parameters which is suitable for every kinds of Yanchang layer, and introduces many fracture technologies and their application's results at the different degree for upgrading single well's production, preventing great out put of sand and restraining bottom water effectively. This matching technology has a guiding sense for fracture test and increasing single well's production rate.
