摘要： An inflating container (2400) filled with formation plugging fluid (2414) is deployed at the target zone by a rigless apparatus. The inflating container can be in valved fluid communication with an explosive filled container (2410), the explosive being ignited using a firing mechanism (2408) that is attached to the explosive filled container. The explosion expands gases in the explosive filled container which pass into the inflation container and displace the formation plugging fluid into the balloon sections (2402) and through the weakened portions of the central balloon (2402b) to penetrate the walls of the target zone. The expanded central balloon is melted by the heat of the chemical reaction and a portion adheres to the formation wall thereby sealing the undesirable target zone; thereafter, the remaining balloon sections are deflated or ruptured to permit the apparatus to be withdrawn through the production tubing.

摘要： A packer having a thermal memory spacing system that includes a portion of the system that that selectively changes an outer diameter due. The packer may include upper and lower sealing elements, and at least one thermal memory shape material sub positioned between the sealing elements. The thermal memory shape material sub may have a first outer diameter at a first temperature and a second larger outer diameter at a second temperature. The first temperature may be greater than the second temperature. The outer diameter of the sub may be selectively increased to temporarily decrease the annular area in which debris and/or materials may collect and potentially cause the packer to become stuck within the wellbore. Prior to moving the packer to a different location, the outer diameter of the sub may be decreased to increase the annular area potentially decreasing the likelihood that the packer becomes stuck.

摘要： The specification discloses a multi-stage injection pipe and method for manufacturing a multi-stage injection pipe. The multi-stage injection pipe includes a plurality of thermocomposite high pressure pipes and a thermocomposite tendon. A jacket surrounds the high pressure pipes and the tendon. The space between the jacket and the high pressure pipes is filled with a matrix material having the same polymer chemistry as the high pressure pipes, the tendon, and the jacket. The multi-stage injection pipe is manufactured by co-extruding the high pressure pipes, the tendon, the matrix material and the jacket, and then allowing the components to bond to one another to maintain the high pressure pipes in position.
