Hydraulic Jetting And Fracturing Tool
Dragging String Hydraulic Jetting Tool
Products Description
Dragging string hydraulic jetting tool is well stimulation which combined of perforating, fracturing and isolation. High-speed liquid that from specialized jetting tools could shoot through casing, rock and shape hole. Bottom hole pressure is increased by annular fluid infusion, which exceed stratum fracturing pressure and crack layer. This method has advantage of deeper than ordinary perforating, aperture is larger and less hurt to stratum.
Dragging string hydraulic jetting tool is well stimulation which combined of Safety joint+ centralizer+ ejector+ packer+ centralizer (hydraulic anchor)+ check valve+ coupling+ screw pipe+ guide head

immovable string hydraulic jetting tool is well stimulation which combined of perforating, fracturing and isolation. High-speed liquid that from specialized jetting tools could shoot through casing, rock and shape hole. Bottom hole pressure is increased by annular fluid infusion, which exceed stratum fracturing pressure and crack layer. This method has advantage of deeper than ordinary perforating, aperture is larger and less hurt to stratum.
Immovable string hydraulic jetting tool: is well stimulation which combined of Safety joint+ N level ejector+…+ primary ejector+ check valve+ coupling+ sieve pipe+ screwed plug
Notes: The coiled tubings are used for connecting all parts.

Products Description
This Ejector is the special jetting tool can generate high-speed fluid to shot through the casings and rocks to form oriented perforations, and the bottom parts of the perforations are cracked and formed gaps depending on the increasing the annular fluid infusion pressure after exceeding the formation fracture pressure. The selective oriented perforating can be realized in a horizontal well. It has a self-sealing effect and is capable of realizing multi-section perforation fracturing interaction.
The single stage ejector can only perforate a place once while going down, but can perforate more than once by dragging the string. When the string support is used, it is matched with the safety joint, the packer, the check valve and others to drag the string to perform perforation fracturing operation.
During the perforation fracturing, the steel ball is located in the check valve connected below the ejector, the diameter of the oil pipe at the lower end of the ejector is sealed, the throttle is generated by the operation of the ground pumping procedure of the field construction when the high pressure fracturing fluid passes through the ejector, and the oil layer is transmitted by an alloy nozzle for perforating and fracturing operation.
Products Description
The K344 expanding packer is an expanding fracturing packer which takes the expansion rubber sleeve as the sealing element, is packed by the hydraulic pressure difference, and is specially used for interlayer packing of the segmental fracturing. The matched compositions of the corresponding downhole tool and the expanding fracturing packer are used for segmental fracturing the construction process string, so as to finish the operation of dragging the multi-layer and multi-section fracturing of separate layers.
Deblocking: after the pressure in the oil pipe is discharged, the pressure difference is disappeared, and the rubber sleeve is withdrawn by the elasticity.
Packing: The oil pipe is added with hydraulic pressure, and the hydraulic pressure is functioned on the inner cavity of the rubber sleeve through the contact water holes below the packer. Due to the function of the pressure difference of the matched throttler, the rubber sleeve is expanded to be glued the casing. Therefore, the annular space of the oil sleeve is sealed.

Products Description
The Y211 packer is the packer for packing and deblocking the compressional one-way slip by upwards lifting and downwards placing the string.
It is used for multi-layer fracturing of the coiled tubing, especially the horizontal fracturing of separate layers. It is matched with the perforating and locating tools and other auxiliary tools to finish well entering once and fracturing operation for multiple times.
