Ultra-Long-Stroke Downhole Pump
LINSON OIL supports ultra-long-stroke downhole-pump selection for rod-driven artificial-lift systems and suitable standalone replacement or upgrade projects. Pump configuration is clarified from the well, completion, fluid, inflow, rod-string motion and operating history rather than from a fixed catalogue duty.
The source portfolio directly documents an Ultra-long stroke oil pump product family. Pump diameter, total length, plunger length, stroke, materials and other listed values remain product/model-specific and are not treated as universal website specifications.
Direct Product Evidence
The final pump must be matched to the actual rod stroke, completion, pump setting, fluid behavior and well operating basis.
Working Principle
Convert rod reciprocation into repeated downhole fluid displacement.
The exact internal valve and sealing arrangement depends on the selected pump model. At page level, the durable engineering logic is to coordinate intake conditions, reciprocating plunger/cylinder motion, controlled fluid transfer and discharge into the production tubing.
Receive Produced Fluid
Pump setting, fluid level/inflow and intake conditions define the available fluid entry basis.
Drive the Plunger / Pumping Element
Rod-string reciprocation produces the project-defined pump motion and displacement cycle.
Control Fluid Transfer
The selected pump's internal flow-control arrangement directs fluid through the pumping cycle.
Lift into Production Tubing
Displaced fluid is routed into the tubing while the complete rod-pump system is checked for interface and operating compatibility.
Selection Map
Select the pump from five connected data groups.
This replaces a generic specification table. The useful procurement question is not “what is the standard pump?” but “what pump fits this well, this rod motion and this fluid?”
Well Geometry
MD/TVD, trajectory, casing/tubing, completion schematic, pump setting and intervention restrictions.
Fluid & Inflow
Oil/water/gas behavior, fluid level/inflow, viscosity, sand/solids, scale/wax and corrosion information where available.
Rod Motion
Rod-string route, surface stroke/frequency, load data and available dynamometer information for existing wells.
Current Pump History
Existing pump type/size/setting, run history, failure mode, wear, gas interference, solids or other operating observations.
Project Scope
Standalone pump vs system supply, connection/interface requirements, inspection, documents, field support and delivery scope.
Rod & Completion Interface
The pump sits inside a larger mechanical chain.
Rod / Lower Connector
Coordinate the lower rod connection with the selected pump product and string configuration.
Pump Setting / Completion
Review seating/installation concept, tubing and completion interfaces against the actual well program.
Surface Motion
For system applications, verify that surface stroke/frequency and rod motion match the downhole pump basis.
Workover / Retrieval
Include access, retrieval, maintenance and intervention requirements in the pump-selection discussion.
Product Evidence
The source brochure directly documents an ultra-long-stroke oil pump product family.
The brochure presents the pump as a core product of the long-life intelligent ultra-long-stroke oil production system and lists model-specific technical parameters. Those values belong to the documented product range and should be matched to the exact model during technical clarification, not generalized as a single standard specification.
Evidence Rule
Later image pass: use the exact pump product page or verified pump photo. Keep model-specific dimensions and operating data attached to that exact model/source only.
Procurement Path
Pump only, or complete lift system.
Complete System
Intelligent Ultra-Long-Stroke Artificial Lift System
Use when surface drive, rod string, pump, wellhead and control are procured as one system.
Rod String
Sucker Rod & Flexible Rod Systems
Coordinate rod route, motion and lower pump connection.
Wellhead
Long-Life Wellhead Sealing Device
Separate moving-rod wellhead sealing interface.
Solution
Intelligent Artificial Lift
Broader well-evaluation and artificial-lift integration context.
Application Evidence
Artificial Lift Application Portfolio
Use verified project/application pages for case-specific well depth, operating parameters and production results.
Ultra-Long-Stroke Downhole Pump RFQ
Send the well, inflow, pump and rod-motion basis.
Share completion schematic, pump setting, tubing/rod information, fluid/inflow data, current pump and operating history, stroke/frequency, failure observations and requested supply boundary.
Detailed datasheets, drawings and project-specific technical documents are prepared after the operating conditions, scope of supply and commercial basis have been sufficiently clarified.
