초록 ▼

A shifting sleeve has differential piston areas so that applied pressure displaces the sleeve against spring bias, which preferably is a series of Belleville washer stacks associated with modular mandrel components, to obtain the desired opposing force to the movement initiated with pressure applied to differential piston areas. An indexing feature is located between the sleeve and the mandrel passage wall and on a predetermined number of cycles disables the Belleville washer stacks from biasing the sleeve in an opposed direction as when pressure is applied. At this time the pressure in the mandrel acting on the differential piston area simply shifts the sleeve to open a lateral port so that fracturing through the cement that was earlier placed with the port closed can take place.

1. An apparatus for cementing and fracturing subterranean locations in a borehole, comprising: a housing having at least one selectively open lateral wall port;at least one sleeve assembly selectively covering said lateral port, said sleeve assembly having an always open passage therethrough for passage of a material therethrough and into an annular space between said housing and the borehole, said sleeve assembly configured to receive a net force from pressure applied from an uphole location to said housing with said wall port closed, said sleeve assembly comprising a biased index mechanism to allow reciprocal sleeve movement for predetermined cycles of pressure application and removal while maintaining said wall port in a closed position, said sleeve assembly moving to open said port after completion of said predetermined cycles for communication to a formation through said open wall port, said biased index mechanism comprising at least one biasing device acting against a j-slot mechanism for said sleeve assembly such that movement of said j-slot mechanism allows a different movement of said sleeve assembly to open said wall port and disable said biasing device source from subsequent movement of said sleeve assembly in at least one direction. 2. The apparatus of claim 1, comprising: said selective movement of said j-slot mechanism allows said net force alone to move said sleeve assembly away from said wall port. 3. The apparatus of claim 1, comprising: said sleeve assembly comprising a selectively engaged lock operative to retain said sleeve assembly after said lateral wall port is opened. 4. The apparatus of claim 1, wherein: said bias for said index mechanism comprises a housing made of modular components each modular component with a biasing assembly selectively engaged to said sleeve assembly. 5. The apparatus of claim 1, comprising: said net force is created as a result of unequal piston areas on opposed ends of said sleeve assembly. 6. The apparatus of claim 1, comprising: releasably retaining said sleeve assembly to said housing with said wall port closed to allow building pressure in said housing at a first predetermined pressure for a pressure test of a tubular string attached to the housing;said lateral wall port opening with pressure lower than said first predetermined pressure applied from an uphole location to said housing with said wall port closed. 7. The apparatus of claim 1, comprising: said index mechanism comprising a rotatably mounted sleeve on an exterior of said sleeve assembly having a slot pattern thereon and a fixed pin on said housing in registry with said slot pattern;said slot pattern having a plurality of short apexes in opposition leading to a long slot;said pin engaged by one of said short apexes as a travel stop for said sleeve assembly when said sleeve assembly moves responsive to said net force from pressure applied from an uphole location to said housing. 8. The apparatus of claim 7, comprising: said short apexes are not engaged by said pin when said sleeve assembly is moved by said biasing that comprises at least one spring in said housing selectively retained to said sleeve assembly by an end ring due to said end ring first engaging a stop surface on said housing. 9. The apparatus of claim 8, comprising: said net force acts to move said sleeve assembly in an opposite direction to said at least one spring. 10. The apparatus of claim 1, comprising: said biasing comprises at least one spring on said housing selectively engaging said sleeve assembly;said net force acts to move said sleeve assembly in an opposite direction to said at least one spring. 11. An apparatus for cementing and fracturing subterranean locations in a borehole, comprising: a housing having at least one selectively open lateral wall port;at least one sleeve assembly selectively covering said lateral port, said sleeve assembly having an always open passage therethrough for passage of a material therethrough and into an annular space between said housing and the borehole, said sleeve assembly configured to receive a net force from pressure applied from an uphole location to said housing with said wall port closed, said sleeve assembly comprising a biased index mechanism to allow reciprocal sleeve movement for predetermined cycles of pressure application and removal while maintaining said wall port in a closed position, said sleeve assembly moving clear of said port after completion of said predetermined cycles for fracturing through said open wall port;said bias for said index mechanism comprises a housing made of modular components each modular component with a biasing assembly selectively engaged to said sleeve assembly;said biasing assembly comprises at least one spring fixedly supported in a respective modular component at one end and having an opposed end movable in tandem with said sleeve assembly under said net force from pressure with an end ring selectively retained to said sleeve assembly. 12. The apparatus of claim 11, wherein: said end ring is retained in a groove in said sleeve assembly by a wall on said modular component for said predetermined cycles whereupon said end ring aligns with a groove on said wall of said modular component to allow disengagement of said end ring from said sleeve assembly. 13. The apparatus of claim 11, comprising: said at least one spring comprises a stack of Belleville washers.
