Mud Cleaner is the second class and the third class solid control equipment which are combined from desander , desilter and underflow screen to treat the drilling fluid
Mud cleaners were developed in the early 1970s to remove fine drilled solids from weighted mud without excessive loss of barite and fluid. They have also proved valuable tools in closed systems and other dry location applications. These devices use a combination of desilting hydrocyclones and very fine mesh vibrating screens (120-400 mesh) to remove fine drilled solids while returning valuable mud additives and liquids back to the active mud system.
Features of mud cleaners:
Shaker: quick screen tensioning system with easy replaced bolts;explosion proof and rated continuous vibration motor;
AWD system: screen basket adjusted within -1°～+5°at 0.5° increment;
feeder box with inlet connection locates on back 10″,1MPa flange.
Desander cones are 10″ or 12″ hydraulic cones and manifold which are made of high-chromium iron while desiter cones are 4″ or 5″ hydraulic cones and manifold of polyurethane.
Desander, desilter and shaker can be used together to process drilling fluid and can also
perform operation independently according to site situations.
Convenient dismantlement and transportation of two parts.
Traditional mud cleaners use multiple 4 or 5cyclones, mounted over a vibrating screen, and are able to effectively process 400-600 GPM. The process capacity is limited by screen capacity and its ability to discard dry solids. With the introduction of linear motion vibrating screens, the capacity of the mud cleaner screen has been greatly increased. This, in turn, allows the use of additional hydrocyclones and higher, overall process capabilities.
DC Machinery mud gas separators are designed to provide safe drilling procedures during horizontal, underbalanced, h2s, or high pressure drilling. Our gas buster captures and separates the mud/gas then safely vents free gas to the flare line to be burned off while returning mud to the mud pits.
DC Machinery separators are intended to sustain safety for high pressure wells or when sour gas may be present. Our units are closed bottom skid mounted model designed around safety and precision. Uniquely designed baffles break up mud and gas which is then expelled by the gas vent line to the flare line.
Highlights of Mud gas separators ：
Designed for horizontal, underbalanced, h2s, or high pressure drilling
Numerous size specifications available
ASME Sec VIII Div 1 Code Vessels
External Pressure Gauge
H2S certified with internal coating
The mud gas separator is manufactured for efficient installation from one rig move to the next. DC Machinery offers rig up of our gas buster and if needed can tie in and/or modify all lines from choke manifold to trip tank, frac tank, panic line, gas buster, and flare line. We supply competitive and cost effective connect and disconnect fees of our equipment.
Vacuum degasser, also known as a mud/gas separator is one of the first units of solids control equipment arranged to treat drilling mud.It is an online degasser system with high efficiency. Dissolved gases are removed from the solvents by applying vacuum to a semi-permeable membrane.
Vacuum degasser applies the vacuum pump suction to form a negative pressure region in vacuum cylinder. The drilling fluids is forced to flow into the hollow shaft of the rotator through suction pipe under the atmosphere pressure. After that, the fluids sprays to cylinder walls out of hollow shaft windows.
Features & Benefits of Drilling Fluids Vacuum Degasser
1. Self contained unit without need for drilling fluid centrifugal pump to feed drilling mud.
2. Eliminate corrosion and reduce reparation and maintenance costs.
3. Short footprint,can be installed in smaller spaces.
4. Drilling fluids degasser can act as a big agitator for the drilling mud, which helps the treatment for drilling fluid desander and drilling mud desilter.
You are welcome to contact with DC Solid control to get more detailed infos, we will supply cost-effective vacuum degasser and satisfactory pre-sale, sale and after-sale technical services.
Sept 16 (Reuters) – U.S. drillers this week added oil rigs for an 11th week in the past 12, according to a closely followed report on Friday, although the rate of increases has slowed as crude prices remain below the key $50 a barrel level that spurs a return to the well pad.
That is, however, the longest streak of not cutting rigs since 2011 with the rig count increasing or holding steady every week so far this quarter.
Drillers added two oil rigs in the week to Sept. 16, bringing the total rig count up to 416, the most since February but still below the 644 rigs seen a year ago, energy services firm Baker Hughes Inc said.
The oil rig count plunged from a record high of 1,609 in October 2014 to a low of 316 in May after crude prices collapsed in the biggest price rout in a generation due to a global oil glut. That decline continued through the first half of this year when drillers cut 206 rigs.
U.S. crude futures were trading at around $43 a barrel on Friday after hitting a five-week low on renewed oversupply fears. They were on track to fall 6 percent for the week on Friday.
“With a large proportion of (rig) gains from smaller operators and oil now sub $45 we would not be surprised to see a flattening or even decline over the next few weeks,” analysts at U.S. financial services firm Cowen & Co said in a report this week.
Longer-term, however, analysts expect the rig count to rise slowly for the rest of 2016 before jumping higher over the next two years with a rebalancing of supply and demand. While U.S. oil futures for the balance of 2016 are only fetching around $44 per barrel, calendars 2017 and 2018 are trading near $48 and $50, respectively.
Analysts at Simmons & Co, energy specialists at U.S. investment bank Piper Jaffray, forecast total oil and natural gas rigs would average 498 in 2016, 704 in 2017 and 981 in 2018.
That, however, is not much higher than the average 479 oil and gas rigs that Baker Hughes said were active since the start of the year. In 2015, the total rig count averaged 978.
Since total rigs fell to 404 in May, the lowest since at least 1940, Baker Hughes said more than two-thirds of the additions have been in the Permian basin in west Texas and eastern New Mexico, the nation’s largest shale oil play.
Anadarko this week said it would boost capital spending and add four rigs by the end of the year, two in the Delaware basin in the Permian and two in the DJ Basin in Colorado.
ZCQ series Vacuum Degasser is a special-purpose device and a new type one for the treatment of gas in the drilling fluids. When drill above 3000m well will using vacuum degasser to wipe off the invaded gas in drilling fluid.
DC Solid control provides 4 models vacuum degasser; They are ZCQ240, ZCQ270, ZCQ300 and ZCQ360. Now we have them in stock for urgent requirements and enjoy big discount.
Vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost. Also, at the same time vacuum degasser can be used as a heavy-power agitator and supported applicable to all types of mud circulation purification system. The vaccum degasser design of the structure is scientific and rational. So we are able to achieve an effective gas-liquid separation, filter out impurities and to ensure that the exhaust pipe is always smooth.
Vacuum degasser are put downstream from separators, shale shaker products, followed by hydro cyclones and centrifuges, if you want to know about it, please directly leave your message in my blog.

The fluid coupling has been widely used in the transmission system of the centrifuge in order to control the centrifuge overload effectively and make it start and operate smoothly, or meet the requirements of speed adjustment.
Hydraulic coupling is a kind of hydraulic transmission device, which uses the liquid dynamic pressure to transmit power and torque. The fluid coupling is made up of working wheel, shell, output shaft, bearing, sealing ring and other components.
There are working fluid (mineral oil) filled in the shell. And the working wheel connected with the motor shaft will change the mechanical energy that input into kinetic energy of liquid, it is equivalent to the working wheel of centrifugal pump, and commonly known as the pump wheel.
Working wheel is equivalent to the working wheel of water turbine, commonly known as turbine. It restores the kinetic energy of the working fluid to mechanical energy, and drives the load through the output shaft. The shell is connected to the pump wheel to form a container for receiving the working fluid. The speed of the turbine is lower than the pump wheel, the relative slip rate is 3%-4% and the efficiency is 96%-98%.
