TMC POWER MAN™ pneumohydraulic drive of the downhole sucker-rod pump with 30 to 140 kN load on the wellhead rod

Purpose

Field of application

• Well development after drilling and workover.
• Operational selection of optimal well operation parameters during the development period.
• Operation on wells equipped with single-lift equipment for the separate production (ESP).
• Watercut studies owing to the possibility of operational changes in parameters of operation of the downhole sucker-rod pump plunger when switching from one formation to another (within 5 minutes by one operator).
• Operation of intermittently operating well stock that has been rendered inactive. Possibility to operate the downhole suckerrod pump in wide ranges; the minimum stroke length is 0.82 ft.
• Conducting reestablishment works on wells with the risk of rod string catching and jamming.

Advantages over traditional drives

• Multiple times lower specific quantity of metal and weight compared to other downhole sucker-rod pump drives up to 70%.
• Reduction of assembling and dismantling and commissioning time by up to 60%.
• Remote control of the hydraulic drive and automatic maintenance of operating modes.
• Continuously variable number of swings and pump plunger stroke length without stopping the drive by one operator within 5 minutes.
• Delay of the pump plunger in the upper position (an increase of the pump fill rate).
• Availability of the spudding function (to take the well out of jamming).
• Reducing energy costs by up to 30%.
• The hydraulic drive is programmed for maximum well delivery and for optimization of specific power consumption and dynamic level.
• Reduced equipment wear and increased well’s inter-overhaul time.
• Operation of three wells with a single hydraulic drive (special version of the hydraulic drive) °F ™ Ø.

Support equipment (at customer's option)

• Rod rotator (RR).
• Special shelter (booth) for the hydraulic power unit in explosionproof and hufter-proof versions.
• Remote control function with the possibility of changing parameters, remote monitoring, and online control of hydraulic drive operation from the operator console.
