摘要： A method and apparatus for isolating formation zones preferably with a memory based material formed into an expansion element, with an outer diameter larger than a borehole, adjacent to a radially telescoping perforation element, converting the memory based expansion element to a stable, smaller, run-in diameter, running it into the borehole, then allowing the memory based material to expand and seal against the borehole wall. Expansion can be enhanced by expanding a mandrel on which the expansion element is formed. The expansion element separates two or more groups of outwardly radially telescoping perforation elements, to isolate formation zones and allow the perforation elements to access the isolated zones.

摘要： A perforating gun connector comprising a first and second section connected together on one end. The two sections of the perforating gun connector that couple together are correspondingly tapered so that one end of one connector is tapered and fits into the corresponding tapered hollowed section of one end of the other section. The present invention also provides for the inclusion of shaped charges and booster charges within. Adjacent the charges are sealing bulkheads.
