摘要
介绍了探井入井流体的检测工作。从室内测定的岩心渗透率恢复值、表皮系数S值和堵塞比DR值,说明目前探井使用的入井流体和工艺技术是能够满足探井地质和工程需要的。现场测试的S值和DR值小于室内测定的S值和DR值,说明固井和射孔的污染较小。
Influence of drilling and completion fluid on reservoir permeability in inspecting well is studied. Return permeability, skin factor (S) and damage ratio (DR) determined in laboratory test indicate that drilling and completion fluid and related technology adopted in inspecting well in China can satisfy the engineering requirment. Skin factor and damage ratio determined in field test are lower than that of determined in laboratory test, this fact indicate that the formation damage during cementing and perforating operation is lower.
