用于选择性处理射孔套管的方法和装置
摘要：
本发明提供一种处理井的近井区域和/或远井区域的方法，其中，在所述井内，储层内的井筒被装有对物质可渗透的管，所述管与井筒形成环空，所述区域在管之外被局限在环空和/或储层内，并且其中该方法包括步骤：(i)将由套筒环绕的坐封部分放置在所述管内靠近将被处理的区域，所述套筒是可膨胀的并且对所述物质是不可渗透的；(ii)膨胀套筒以使所述套筒与将被处理的区域附近的所述管接触，确保所述管的第一区域对所述物质不渗透，但是第二区域对所述物质可渗透；(iii)泵送处理流体到将被处理的区域，所述处理流体经由仍对所述物质可渗透的所述第二区域进入环空；和(iv)利用所述处理流体处理将被处理的所述近井区域和/或所述远井区域。同样，本发明提供一种用于处理井的近井区域和/或远井区域的装置，所述区域被局限在被置于井内并与井筒形成环空的管之外，所述管对物质是可渗透的，所述装置包括：(i)由套筒环绕的坐封部分，所述套筒是可膨胀的并且对所述物质不可渗透的；(ii)用于膨胀套筒的膨胀部件，所述膨胀部件确保所述套筒与所述管的第一区域接触，以使所述管的所述第一区域对所述物质是不渗透的；和(iii)用于将处理流体输送到将被处理的区域的输送开口，所述输送开口确保所述处理流体经由仍对所述物质可渗透的第二区域进入环空。
摘要（英）：

The invention provides a method of treatment of a zone of a well, wherein inside the well, a wellbore in a formation is filled with a tube which is permeable to a material, the tube forming an annulus with the wellbore, and the zone being localized beyond the tube in the annulus and/or in the formation, and wherein the method comprises the steps: (i) placing inside the tube a setting section surrounded by a sleeve near the zone to treat, the sleeve being expandable and impermeable to the material; (ii) inflating the sleeve so that the sleeve is in contact with the tube near the zone to treat, ensuring for a first zone of the tube impermeability to the material, but leaving a second zone permeable to the material; (iii) pumping a treatment fluid to the zone to treat, the treatment fluid passing into the annulus via the second zone still permeable to the material; and (iv) treating the zone to treat with the treatment fluid. Also, the invention provides an apparatus for treatment of a zone of a well, the zone being localized beyond a tube placed inside the well and forming an annulus with a wellbore, the tube being permeable to a material, and the apparatus comprising: (i) a setting section surrounded by a sleeve, the sleeve being expandable and impermeable to the material; (ii) an inflating means for inflating the sleeve, the inflating means ensuring that the sleeve is in contact with a first zone of the tube so that the first zone of the tube becomes impermeable to the material; and (iii) a delivery opening for delivering a treatment fluid to the zone to treat, the delivery opening ensuring that the treatment fluid passes into the annulus via a second zone still permeable to said material.
