摘要： A fracturing tool features spaced releasable packers with an outlet in between. The housing has relatively moving components for opening the frac port between the packers with weight set on the lower packer. Once the frac port is opened the upper packer is set and the pumping begins. The upper packer can be released so that tension can be pulled on the lower packer to close the frac port and open a through passage in the housing. In one embodiment the through passage can be located above the lower packer to a sand jet perforator to clean debris away from the lower packer if it is difficult to release the lower packer or to abrasively perforate through a tubular. In another embodiment the housing outlet can be below bottom packer to perform a treatment further downhole or to operate another tool. The straddle tool can be run in on coiled tubing.
摘要翻译：
一种压裂工具具有隔开的可拆卸封隔器，其间具有出口。壳体具有相对移动的部件，用于打开位于封隔器之间的压裂端口，并在下封隔器上设置重量。一旦压裂端口被打开，上封隔器被设置并开始泵送。上封隔器可以被释放，使得下封隔器上的张力可以被拉动以关闭压裂端口并打开外壳中的贯通通道。在一个实施例中，如果穿过通道难以释放下封隔器或磨蚀穿孔穿过管件，则穿过通道可位于下封隔器上方至喷砂穿孔器，以清除远离下封隔器的碎屑。在另一个实施例中，壳体出口可以在底部封隔器的下方以进一步在井下进行处理或操作另一工具。跨接工具可以运行在连续油管上。
