摘要:

在实验室条件下对贝雷砂岩进行射孔试验,并分别对射孔后的靶体进行酸化、压裂工艺处理,利用核磁共振和工业XCT技术分别对未射孔的靶体、射孔后的靶体、射孔后酸化的靶体、射孔后压裂的靶体进行测试。定量分析了射孔对砂岩靶体的损害及酸化、压裂对射孔损害的解除作用,并进行现场试验验证。对合理有效地规划油田采油工艺具有一定的参考价值和指导意义。

Abstract: Acidizing and fracturing are performed on perforated Berea sandstone targets after perforating tests in labs. Nuclear magnetic resonance and industrial XCT tests are followed on the imperforated, perforated, acidized perforated and fractured perforated targets. Perforating damages on sandstone targets and the solution of this problem by acidizing and fracturing are quantitatively analyzed, the result was tested on site.

Key words: Berea sandstone, perforation, acidizing, Fracturing, NMR
