摘要： The present invention relates to systems and methods useful in subterranean treatment operations. Examples of methods of the present invention include methods for fracturing a portion of a subterranean formation penetrated by a well bore; methods of enhancing production from multiple subterranean formations penetrated by a well bore during a single trip through the well bore; and methods of enhancing production, in real time, from multiple subterranean formations penetrated by a well bore during a single trip through the well bore.

摘要： The present invention is directed to a bottom-up method of fracturing a multi-zone subterranean formation intersected by a wellbore that enables one zone to be fractured while at the same time flowing previously placed fracture fluid from one or more other zones back to the surface. The method employs a bottom-hole assembly (“BHA”) that is attached to the bottom end of a tubing string. The BHA includes a hydra jetting sub, a centralizer, a packer and valve sub. The hydra jetting sub is used to perforate and initiate the fracture in the zones of interest. The zones are fractured by pumping fracturing fluid down the annulus formed between the tubing string and the wellbore. The previously placed fracture fluid flows back to the surface through the tubing string. It enters through the valve sub in the BHA.
摘要翻译：本发明涉及一种自下而上的方法，用于压裂由井眼相交的多区域地层，其使得一个区域能够断裂，同时将来自一个或多个其它区域的先前放置的断裂流体回流到表面。该方法采用连接到油管柱底端的底孔组件（“BHA”）。 BHA包括Hydra喷射子，扶正器，封隔器和阀门。 Hydra喷射sub用于在感兴趣的区域穿孔并发起断裂。通过将压裂流体沿着在油管柱和井筒之间形成的环形空间进行压裂而使区域断裂。先前放置的断裂流体通过油管柱回流到表面。它通过BHA中的阀门进入。

摘要： An example of a method includes providing a hydrajetting tool in a well bore in a formation; injecting a fluid through the tool into a first region of the formation at a velocity sufficient to form one or more perforation tunnels; maintaining the flow of fluid into the perforation tunnels at a pressure greater than the fracture closure pressure, so as to create one or more fractures in the first region; plugging at least partially the fractures with an isolation fluid; injecting a fluid through the hydrajetting tool into a second region of the formation at a velocity sufficient to form one or more perforation tunnels in the second region; and maintaining the flow of fluid into the perforation tunnels in the second region at a pressure greater than the fracture closure pressure, so as to create one or more fractures in the second region.
