Abstract: A method of and apparatus for treating a zone in a well is disclosed. A tube that is permeable to a material is inserted into a wellbore, creating an annulus inside the wellbore. Two zones—the annular region and the formation surrounding the wellbore—may be treated. The method comprises the following steps. (1) A setting section surrounded by a sleeve is placed inside the tube near the zone to treat, the sleeve being expandable and impermeable to the material. (2) The sleeve is inflated inside the tube near the zone to treat, ensuring that a first zone of the tube is impermeable to the material, but leaving a second zone permeable to the material. (3) A treatment fluid is pumped to the zone to treat, the treatment fluid passing into the annulus via the second zone. (4) The zone to treat is treated with the treatment fluid.

Abstract translation: 公开了一种处理井中区域的方法和设备。 将可渗透材料的管子插入井筒中，在井眼内部形成环形空间。 可以处理两个区域 - 环形区域和围绕井筒的地层。 该方法包括以下步骤。 （1）由套筒包围的设置部分放置在靠近该区域的管内部，以便处理该套筒，该套筒可膨胀并且不可透过该材料。 （2）套管在管内靠近该区域进行充气以进行处理，确保管的第一区域不可透过材料，但留下可渗透材料的第二区域。 （3）处理流体被泵送到区域以处理经由第二区域进入环形空间的处理流体。 （4）处理区用处理液处理。
