摘要： A method and apparatus are disclosed which allow isolation of a plurality of zones for treatment, particularly sand fracturing. The lowermost barrier can be pumped through tubing (12) and anchored in cased or open holes. In the preferred embodiment, the pumped plug (20) has a visco-elastic member (74) which contains a particulate aggregate mixture (87), such as described in U.S. Patent 5,417,285. The visco-elastic material is subjected to a force which changes its shape so that the material obstructs the wellbore. The shape change also accomplishes dehydration of the material within the visco-elastic enclosure by virtue of fluid displacement, resulting from a volume reduction, hardening it so that a plug using the visco-elastic material is formed. Thereafter, a packer (14) on the tubing string (12) is set to isolate the zone for sand fracturing. The process can be repeated without tripping out of the hole as additional plugs are pumped through tubing and the process is repeated. At the conclusion of the fracturing, the various plugs, which are of simple and economical construction, can be readily milled out.

摘要： A high-pressure casing fill-up and circulating assembly and method of use is disclosed. The fill and circulating assembly, when inserted into the uppermost portion of the casing, will allow the casing to be filled while each section of casing is added. In one configuration there can be a cup type seal that seals in the casing simply by inserting the circulator into the casing. In yet another configuration the casing circulator portion can be anchored in the casing by manipulating the setting apparatus of the circulator thus anchoring the circulator to the casing and a settable seal unit will be energized to seal between the casing and the circulator.

摘要： Slip members for use with downhole tools comprise a body formed of a first or body material and one or more hard material elements formed of a second or element material. The element material is harder than the body material. The hard material element is disposed through the body and in communication with a first surface and a second surface of the body, the second surface being disposed opposing the first surface. During manufacturing of the slip members, the hard material element may extend outwardly from one or both of the first and second surfaces. After manufacturing, the hard material element can be shaped to provide a gripping member.

摘要： A method and apparatus are disclosed which allow isolation of a plurality of zones for treatment, particularly sand fracturing. The lowermost barrier can be pumped through tubing (12) and anchored in cased or open holes. In the preferred embodiment, the pumped plug (20) has a visco-elastic member (74) which contains a particulate aggregate mixture (87), such as described in U.S. Patent 5,417,285. The visco-elastic material is subjected to a force which changes its shape so that the material obstructs the wellbore. The shape change also accomplishes dehydration of the material within the visco-elastic enclosure by virtue of fluid displacement, resulting from a volume reduction, hardening it so that a plug using the visco-elastic material is formed. Thereafter, a packer (14) on the tubing string (12) is set to isolate the zone for sand fracturing. The process can be repeated without tripping out of the hole as additional plugs are pumped through tubing and the process is repeated. At the conclusion of the fracturing, the various plugs, which are of simple and economical construction, can be readily milled out.
摘要翻译：公开了一种方法和装置，其允许分离多个用于处理的区域，特别是压裂砂。最下面的障碍物可以通过管道（12）泵送并锚定在套管或敞开的孔中。在优选实施例中，抽吸塞子（20）具有包含颗粒聚集体混合物（87）的粘弹性构件（74），如美国专利5,417,285中所述。粘弹性材料受到改变其形状的力，使得材料阻碍井眼。形状变化还通过流体移动来实现粘弹性外壳内的材料的脱水，由体积减小导致其硬化，从而形成使用粘弹性材料的塞子。此后，设置管柱（12）上的封隔器（14）以隔离用于砂压的区域。当额外的塞子被泵送通过管道并且重复该过程时，可以重复该过程而不脱离孔。在断裂结束时，可以容易地研磨出简单经济的各种塞子。
