摘要： The invention provides an apparatus and method for perforating and treating multiple intervals of one or more subterranean formations intersected by a wellbore by deploying a bottom-hole assembly (“BHA”) having a perforating device and at least one sealing mechanism within said wellbore. The BHA may be deployed in the wellbore using a tubing string or cable; or alternatively, the BHA may be deployed using a tractor system attached directly to the BHA. The perforating device is used to perforate the first interval to be treated. Then the BHA is positioned within the wellbore such that the sealing mechanism, when actuated, establishes a hydraulic seal in the wellbore to positively force fluid to enter the perforations corresponding to the first interval to be treated. A treating fluid is then pumped down the wellbore and into the perforations created in the perforated interval. The sealing mechanism is released, and the steps are then repeated for as many intervals as desired, without removing the BHA from said wellbore.
摘要翻译：本发明提供了一种用于通过展开具有穿孔装置的底孔组件（“BHA”）和在所述井眼内的至少一个密封机构来穿孔和处理与井眼相交的一个或多个地层的多个间隔的装置和方法。 BHA可以使用油管柱或电缆部署在井眼中; 或者可以使用直接连接到BHA的拖拉机系统来部署BHA。穿孔装置用于穿透待治疗的第一间隔。然后，BHA定位在井眼内，使得密封机构在致动时在井筒中建立液压密封，以积极地迫使流体进入对应于待处理的第一间隔的穿孔。然后将处理流体向下泵送到井眼并进入在穿孔间隔中产生的穿孔中。释放密封机构，然后根据需要重复该步骤达到多个间隔，而不从所述井孔中移除BHA。

摘要： Autonomous units and methods for downhole, multi-zone perforation and fracture stimulation for hydrocarbon production. The autonomous unit may be a perforating gun assembly, a bridge plug assembly, or fracturing plug assembly. The autonomous units are dimensioned and arranged to be deployed within a wellbore without an electric wireline. The autonomous units may be fabricated from a friable material so as to self-destruct upon receiving a signal. The autonomous units include a position locator for sensing the presence of objects along the wellbore and generating depth signals in response. The autonomous units also include an on-board controller for processing the depth signals and for activating an actuatable tool at a zone of interest.
