摘要： A method and apparatus for controlling inflation and deflation of spaced inflatable packer elements of a straddle stimulation tool within a well casing of a well. A straddle stimulation tool is positioned by tubing at a desired location within the well casing. Fluid is pumped through the tubing and tool at a rate inflating the spaced inflatable packer elements within the well casing and establishing an annulus interval. The inflation control retains pressure within the inflated packer elements and permits the flow of stimulation fluid into the annulus interval for stimulation of the formation. After completion of well stimulation, the packer element pressure control is moved to a packer equalizing position by tension applied via the tubing to equalize packer pressure with casing annulus pressure, deflating the packer elements and permitting conveyance of the straddle stimulation tool within the well casing by the tubing string.

摘要： A method for actuating or installing downhole equipment in a wellbore using non-acoustic signals (e.g. radio frequency signals) to locate, inventory, install, or actuate one downhole structure in relation to another downhole structure is shown in Figure 3. The method comprises the steps of: (a) providing a first downhole structure (12) that comprises a non-acoustic (e.g., radio frequency) identification transmitter unit (28) that stores an identification code and transmits a signal corresponding to the identification code; (b) providing a second downhole structure (32) that comprises a non-acoustic receiver unit (34) that can receive the signal transmitted by the non-acoustic identification transmitter unit, wherein one of the first downhole structure and the second downhole structure is secured at a given location in a subterranean wellbore, and the other is moveable in the wellbore; (c) placing the second downhole structure in close enough proximity to the first downhole structure so that the non-acoustic receiver unit can receive the signal transmitted by the non-acoustic identification transmitter unit; (d) comparing the identification code from the transmitter with a target code in the receiver; and (e) if the codes match, actuating or installing a downhole structure.
