Q195 HDD Oil Well Drilling Mud Equipment 80m3/H Reclaiming

HDD mud recycling system is the drilling fluid process system similar as oil well drilling mud system

Composition Of Mud Recycling System

Mud Recycling system contains shale shaker, mud cleaner or desander / desilter, centrifugal pump, mud tank, mud agitator, etc. The mud recycling system normally used for horizontal directional drilling ( HDD ) or coal bed methan ( CBM ) with compact design. There are many manufacturers in China but different manufacturer do different design. Many of them focus on oil and gas industry solids control system design, so they supply mud recycling system for HDD or CBM with an oil and gas brain, that’s good as they are same working procedure but HDD or CBM designed mud recycling system normally need special design, many supplier just keep an oil & gas brain and may ignore the different working habit and conditions.

Specification

Professional mud recycling system manufacturer 

AIPU Solids Control worked a lot in oil and gas industry, we had an brain for oil and gas only but find many client in HDD / CBM for different idears of tank design and arrangement. CBM and HDD drilling normally require very compact design for fast installation and movement. Such as the shale shaker for oil and gas drilling normally too long and the HDD / CBM shaker need shorter to sit on tank width, so shaker can be delivery together with tank without moving. There need keep an eye when designed the whole system and keep sure total width and height not exceeding local transport limit.

HDD mud recycling system working procudure 

1. There is a drill pit at each side of drilling hole, a set of vertical slurry pump will set on top of mud pit for feeding shale shaker. The shale shaker screen will separate drilling cuttings and discharge out, fluids part will drop into sand trap through screen hole.

2. 1 or 2 or 3 sets of desander cyclone sit after shale shaker, one set of centrifugal pump will feed desander cyclong for second phase separation, solids out of desander will be discharge to shaker screen or cutting box directly and fluids over flow from desander will flow into desander compartment.

3. A quantity of desilter cyclones will sit after desander for fine solids separation, solids out of desilter will discharge to shaker screen or cuttings box, fluids over from desilter will drop into desilter compartment.

4. A mixing pump sit on tank skid for drilling mud transfer and feed mud into mud hopper for new mud remix by new chemicals. The mixing hopper can sit on top of tank or tank skid as per client’s demand.

Standard Equipment But Custmized Design

Many mud recycling system supplier has standard design of mud recycling system, this is same with AIPU solids Control. But we supply customized design with standard equipment and tank design depending on client request. This is very important cause different drilling site may need different footprint, tank and compartment design or transport request. AIPU will designed based on our professional knowledge and client drilling conditions for a better solution for each client.

Mud recycling system application and effect

Mud reclaiming recycling mixing system is designed for mud recycling of trenchless. Such as tunneling shield, HDD, and pilings. It can help reduce costs and improve construction efficiency significantly.
The whole system consists of a mud recovery treatment unit and a mud preparation unit.
Before construction, using mud mixing device to blend freshwater with mud material, achieving the purpose of mud preparation;
Using a mud pump to supply the prepared slurry to the wellhead;
Return of waste mud from the wellhead is pumped to the shale shaker in the mud treatment unit, and the waste mud is removed through the mud shale shaker to remove a large amount of the waste solid particles. The treated slurry liquid will continue to be supplied to mud cleaner through the sand pump, after treatment the liquid can meet user requirements. Because after this system treated, solid particles content in the slurry liquid is 75 microns.
