新型符合桥塞 提速增产作业

Forum Energy Technologies’ family of ProDrill® composite bridge and frac plugs are designed to reliably provide temporary zonal isolation during stage fracs in horizontal and vertical wells. These plugs, which are a critical component in completing plug-and-perf operations, are constructed with premium composite materials. The plugs help mitigate risk during drillout, while decreasing time on location and costs to complete unconventional wells.

Forum is a global provider of engineered completion and downhole solutions and products that can be tailored and packaged to the technical specifications of each well design. We’re completely focused on optimizing upstream completion costs for each operator.

ProDrill® Velocity™ LSG

The Forum Energy Technologies ProDrill® Velocity™ LSG, fast-drillout composite frac plug is a critical component when completing plug-and-perf operations. This solution optimizes well completions efficiency by reducing drillout times, debris size and the amount of material that needs to be circulated out of the hole. The ProDrill Velocity composite plug mitigates risk during drillout, while decreasing time on location and costs to complete unconventional wells.

The set-from-bottom, compression-set plug design minimizes run risk by transmitting impacts through the wireline adapter kit (WLAK) tension mandrel, which also reduces stresses on critical elements of the plug. Once set, this design keeps the plug in the set position during and after fracturing operations.
The design is unique in that the components do not slide on a stationary mandrel like typical composite plugs. This allows the reduced-length, fully optimized composite plug to shorten when set and mitigate spinning components during drillout. The short one-slip plug reduces the amount and size of material that is circulated out of the hole, reducing both risk and time. The plug is available in a top-ball configuration for 5.5. 17-23# casing in 10,000 psi 300F applications. A top ball plug for 4.5-in 9.5-13.5# is currently in development.

With an easily drillable low-specific gravity (LSG) option of 1.6, the magnesium alloy slip, with ceramic buttons, further improves efficiency of the plug. Since the slip’s material is lighter than composite, it provides a clean well post-drillout, even in low bottomhole pressure wellbores.

APPLICATIONS

• Unconventional wells
• Multizone completions
• Plug-and-perf completions

BENEFITS

• Lowers costs and time to complete, up to a 65% reduction in drillout times over traditional composite plug designs
• Minimizes risk and drillout time, with a 50% reduction in length and a 50% reduction in weight of material to be drilled and circulated out of the hole
• Decreases time and water consumption since the symmetrical lightweight design allows more efficient horizontal pumpdown operations
• Mitigates risk with a simple one-slip, set-from-bottom, compression-set design, which withstands debris impacts

FEATURES

• Optimized one-slip design reduces particle size and material to circulate out of hole
• Compression-set design eliminates critical components from being put in tension during the setting sequence and keeps the plug in the locked position during and after fracturing
• Bottom-set, anti-preset configuration mitigates impacts during pumpdown operations
• Recessed ball seat keeps ball from spinning during drillout
• Unique plug configuration that shortens in the set position, reduces amount of material to drill and circulate out of the well

ProDrill® Express Series Composite Plugs 

Forum Energy Technologies’ ProDrill Express Series bridge and frac plugs offer a dependable, durable and cost-effective method to temporarily isolate zones during hydraulic fracturing operations in both vertical and horizontal wells. The plugs uniquely combime composites with cast-iron slips, helping to reduce drillout times (consistent times of 13to20 minutes or less), while remaining reliable

The ProDrill Express plugs are manufactured with proprietary material, which allows the multiconfiguration adapters to be threaded in the inner diameter (ID) mandrel, making it a fully internal composite tool, No brass or aluminum conversion accessories are required, improving drillout times and reducing risks. Cast-iron slips are hardened to wicker depth only, and can be set in up to P110 casing.

The multiconfiguration plug allows the user to easily convert it from a ball-drop solution to a caged-ball flowback or solid bridge plug using two simple kits. The plugs can be run with any wireline-setting tool or tubing-run hydraulic setting tool. Plugs are currently available for the following casing sizes, 3 ”/z, 4’h, 5 1/2, and 7 in.

Ball-Drop Frat Plug Configuration

After the ProDrill Express ball-drop frac plug is set, the ID remains open, allowing work to continue above. A ball is then dropped from the surface and pumped dawn until it seats on the tool. Once the ball is seated, the operator can pressure up against the frac plug, The ball can also be run in place, between the shear sleeve adapter and mandrel allowing it to be used as a flowback plug without having to drop the Gall from surface

Caged-Ball Frac Plug Configuration

The caged-ball frac plug utilizes simple ball/cage adapter that houses a 3/4in composite ball in the upper ID of the plug, When zonal pressure is greater from below the plug, the ball cage allows the lower and upper zones to communicate. When zonal pressure is greater from above, the ball seats; thus, isolating the zones

Bridge Plug Configuration

The Express Series bridge plug is converted using a simple composite bridging pin that is threaded into the mandrel while sealing in the ID. This plugged ID is drilled out before the top slip; thus, allowing the upper and lower zones to equalize during drillout. The operating range listed in the specitication table refers to the difterential pressure rating from above. The differential pressure rating from below is 6000psi.
