Relative to the use of drilling fluids within the oil and gas industry, the use of drilling fluids within the horizontal directional drilling (HDD) industry is new. Even today, the amount of research and development aimed at HDD drilling fluids is considered a rounding error in the oligopoly of drilling fluid manufacturers.
However, the trends strongly suggest that the future of HDD drilling will follow a similar evolution as experienced by the traditional oil and gas industry.
Solid control

A typical HDD solids control system will employ a combination of shaker, hydrocyclone, mixing, pump and compartmentalized tank technologies. The shaker is vital to the solids control system and is considered the first line of defense. Located directly downstream from the shaker will likely be a hydrocyclone assembly that will employ
desilters, desanders or both. Though still considered rare, centrifuge-enable solids control systems are becoming more popular. By adding a centrifuge, the solids control system will achieve the highest level of cut available within the market today.

HDD mud system

The features of the HDD mud recycling system from DC Solid control has the compact structure, small occupied area, good sand removing effect, can reduce the mud loss, relocation less haulage vehicle, labor saving, not easily damaged parts, and can prolong the service life. The mud tank is suitable for oil drilling mud purification processing and storage. The mud tank is generally customized with different size and data.

Besides the standard drilling mud recycling system, DC also provide customized mud recycling system accordling to drilling contractors applications.If you want to find

Along with the drilling fluid, a reliable method of delivery to the drill is needed. This is called a mixing system or mud system. The mud system delivers the fluid to an onboard pump (on smaller horizontal directional drills) or a standalone pump that feeds into a larger rig (generally 100,000-pound capacity or larger.) With the rise of mud recycling in drilling, reclaimers are becoming more prominent on jobsites.

These are a type of mud system that “cleans” the used mud and recirculates it back into the mixing system to be reused. An HDD contractor needs to make sure to use the right kind of mud and the proper equipment to effectively supply the correct amount of fluid into the pump and downhole.

mud system

Rising costs of mud disposal and the limited availability of disposal sites are driving some HDD contractors to reuse their drilling fluid, which requires a reclaimer. Environmental concerns are also a factor so we are seeing more reclaimers required in drilling specs,” says Heinen. “Also mud disposal is cost prohibitive and we are seeing an increase in mud recycling requirements on job sites.”

The reclaimer is generally configured with multiple tanks which can include a clean mud tank, a dirty fluid tank and a desander and/or desilter tank. Dirty fluid is drawn from the return pit and pumped across the first cut shaker(s), which sift out all the larger particles of sand and debris. Then the fluid is pumped through the desander cones where a cyclonic motion is used to eliminate even smaller particles, and again across a shaker screen equipped with a finer mesh screen to further the cleaning process. The fluid finally passes through desilter cones and again across a final set of shakers and screens, which separate out the smallest micron particles from the drilling fluid completing the cleaning process. Each deck on the reclaimer uses progressively smaller screens to remove micron-sized elements from the fluid.
Once through, the fluid is stored in the clean mud tank ready to be recirculated back down hole.

Mud Tank System is a part of circulatory system of the rig, used for storing and feeding the required drilling fluid during Rig operation cycle. Mud Tank System is available for different drilling rig sizes from 250HP to 3000 HP with different capacity.

Normally, a complete mud tank system consists of a mud tank with compartments for both incoming dirty and cleaned fluid, a shale shaker, a desander (depending upon the size of the unit), and a desilter. The shale shaker separates larger solids approximately 400 micron and larger, the desander separates solids approximately 100 micron and larger, and the desilter separates solids approximately 40 micron and larger. After the fluid processes through the desilter and deposited into the clean tank, it can then be pumped to the mud pump to be pumped back downhole.

Mud agitator is used on the mud tank is used in surface mud systems to suspend solids and maintain homogeneous mixture throughout the system. A mechanical agitator is driven by an explosion-proof motor, coupled to a gear box that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation. The objective is to obtain a uniform suspension of all solids.

Drilling rig mud agitator used in oilfield to mix drilling mud.

1. The main models of mud agitator designed, developed and produced by the company are JBQ-22, JBQ18.5, JBQ15, JBQ11, JBQ7.5 and JBQ5.5. The reducer adopts worm or worm wheel, with tight structure, good meshing performance and reliable work.
2. The explosion-proof electric machine and reducer input shaft are connected through elastic shaft coupling instead of belt transmission, and therefore the rotation speed of the wave wheel is constant, the mixing intensity is large and the range is wide, which has structurally avoided the phenomenon of engines overload at startup, suitable for wild field operation under poor conditions, and it is convenient to be installed, regulated or replaced.

Most recyclers today use orbital, elliptical or linear motion shakers, and each has a place in different drilling scenarios. With that being said, linear motion shakers generate high G-Forces and are especially effective in shallow formation sections where high-volume, heavy solids are encountered, and have the ability to remove the solids quickly.

shale shaker

When choosing a linear shaker for your mud system, look for a long runway (area of length from the front of the shaker to the end where the cuttings dump off). The longer length shaker bed allows extra time for solids to separate from the liquid, and result in drier solids leaving the mud system for disposal. You can also increase the angle of the shaker bed by five degrees to further increase the travel time of the solids.

shakers

Proper shaker screen selection enhances the results of the mud recycler, and, combined with the G-Force of the shaker, works in tandem to maximize solids dryness. In the past, shaker screens were sized by mesh size.

Example: 40 mesh screen had 40 openings per square inch of screen area. As a measurement, this left room for a lot of unknown variables, including questioning what gauge wire was used in the manufacture of the screens. The wire gauge altered the size of openings on the screen surface and resulted in changing the size of the solids that the screen could pass or “cut.”

DC Desilter is the third class solids control equipment to treat the drilling fluids. According to the size of the cone diameter, they are divided into Desander and Desilter. Usually the cone diameter is less than 6″is called Desilter, and used as the third-control equipment in drilling operation.

spare parts

We commonly used 5 “and 4″ cone to separate solid-phase particle size 15-47μm in the drilling fluid. Based on customer requirements and capacity, we can select groups of cone into Desilter. DC Desilter works very well with Solids control system other equipment.

Until now we have 12 sets mud desilters used in Singapore building construction fields. Last week we delivery a batch of spare parts to them, include 4″ desilter cones, different size of nozzle, screens and ect.

Desilter

Both Desilters and Desanders are available in a large range of configurations including stand alone, over a shaker as a mud cleaner or packaged with a supply pump as a mobile desilting unit. Please contact our office to discuss applications and appropriate technical specifications.
