Drilling waste management

Drilling and Completion waste generation and classification

Drilling and completion fluids and waste management into solid two elements. when the liquid waste generated from sewerage waste drilling mud separation , wash water well field , formation outflow of water, diesel motor cooling water , improvement instrumentation and wellsite sewerage water , etc. ; solid waste , together with waste drilling mud contamination occurred when separation mud, drilling cuttings square measure contaminated with harmful drilling parcels , wellsite construction residue , contaminated soil , drilling materials and packaging.

Drilling waste management, there square measure several waste substances harmful to humans , significant metal ions , some harmful parts like chemical science , once discharged into the atmosphere round the well web site , can inevitably result in soil, surface water and groundwater pollution , impact on the atmosphere cannot be assess the injury , notably in environmentally sensitive areas , would endanger people's health and life , therefore, the drilling and completion of waste treatment is important .
 

Drilling and Completion standing waste treatment abroad

At present, foreign countries usually price the event of the industry drilling and completion technology, waste disposal , from the start of the last century , the corresponding process instrumentation and installations are within the international advanced level , just like the us , Canada, France and different countries within the drilling method of drilling completed abandoned wells on liquid waste treatment employing a four solids management instrumentation to gather cuttings and dust , so were cured of their waste or transport . usually used instrumentation shale shaker, desander , desilter , decanter centrifuge, and different rubble recovery.

HDD drilling mud system

Aiming at Trenchless Directional Drilling mud purification and recycling system exists using conventional shaker run the risk of mud , grit removal and desilter not complete, mud and other small particles can not clear the problem , brightway can provide the best quality solids control equipment and system .

Using horizontal directional drilling technology for pipeline crossing construction , urban construction and municipal pipe network transformation electrification , communications and cable laying across large and small rivers, lakes, and the demolition of the building can not be the best choice is not to disfigure the state and protection of the environment the best method of construction . In recent years, the level of directional drilling technology in various countries and various sectors of the world has been widely used in China in recent years, with the rapid development of pipeline construction , especially natural gas project construction , directional drilling large diameter pipes began to , long-distance, large wall thickness across the areas of expansion , the level crossing has been greatly improved . Because of the large caliber, long-distance directional drilling developed in recent years , through the introduction of foreign rig the general majority, its ancillary equipment has not attracted much attention , especially in the mud purification and recovery system. However , as people 's awareness of environmental protection , how to conduct safety and environmental protection become directional drilling directional drilling development.


An important issue.
In trenchless directional drilling , due to the hole diameter, such as natural gas and Jining pipeline project , the use of «1 016 mm pipe, in reaming stage , a very large amount of mud . Typically , trenchless directional drilling is the open system , in general through the mud in the amount of 3 000 m3 or more, some even up to 10 000 m3 [1]. Large amount of mud , the mud will not only increase costs and land acquisition costs , more serious problem is through the completion of the waste mud Without effective treatment,

Pollution of farmland and water , will cause ecological problems. As people 's awareness of environmental protection , development and use of mud tank purification and recovery is imperative. Purification and recovery of mud slurry can be returned to solid phase processing and recycling, while reducing the amount of slurry , to reduce environmental pollution and reduce the amount of processing of waste ; the other hand, the recovered slurry are " cooked mud " , the performance is relatively stable, unstable performance can reduce the emergence of underground accidents.

Kem-Tron Tango 500 Mud Recycling System

Kem-Tron mud recycling system is one of the popular mud system in the world . Many users choose Kem-Tron for solutions , here I will introduce one of Kem-Tron mud recycling system for you .
This unit is capable of achieving a cut point of 25 microns. The TANGO 500T has one (1) dual-deck shaker with a total screen surface area of 56 ft2 with six (6) 5” hydrocyclone desilters. The TANGO 500T carries a total tank volume of 3,100 gallons between two (2) compartments along with three (3) 250-Series centrifugal pumps with a respective horsepower rating of 25hp, 20hp, and 20hp. All the pumps are located in the pump house to protect from the elements.
Characteristics of Kem-Tron 500 mud recycling system

Firstly , this mud recycling system is a mobile unit which have wheel at one side of this unit for easy moving . Secondly , it’s a combination of recycling mud part and mixing mud part . Thirdly , This recycling unit don’t have mud agitator which don’t have a good agitate fuction . Forthly , It’s mainly focused on recycling mud not mixing which enabled this system flexible and exquisite.Lastly , the price for this recycling unit is costly .

BW Solids Control is a Chinese manufacturer for mud recycling system and have started to design for mobile system recently . For BW drilling mud system , here is some breif info for that.
Main Equipments and Layout for BW500GPM drilling mud system

1 x linear motion shale shaker BWZS70-3P
1X Mud cleaner BWZS85-1S8N, this is the conbination of desander and desilter.
2x centrifugal pump for mud cleaner
1x mud agitator
1x mud gun
1x jet mud mixer
1x Mud tank

Advantages of BW 500 GPM mud system compared with Kem-Tron

Firstly , processing by pickling, help plating, hot-dip galvanizing, inactivation and fine grind. which is guaranteed the syetem have a longer service life. secondly,mud larger mud capacity so treating effect will be better and mixing fuctions is much better too.

Brandt Shale Shaker VS Brightway Shale shaker

Shale shakers separate solids from liquids by utilizing a vibrating basket, which is outfitted with specially designed and sized screens. Shakers are considered the most important tool for removing drilled solids.

The well-known Brandt shale shaker is produced by National Oilwell Varco, which began to provide the solids control equipment from year 1974.

Brightway respect the leading shale shaker manufacturers including Brandt, and we also persist in our own product improvement to give our wisdom and effort for this industry.

Let's have a comparison between Brandt mini Cobra 3-panel shaker and Brightway liner motion 3-panel shale shaker.



Brandt mini Cobra 3-panel shaker shaker:

We can see the difference from the picture and specification, but we can also see the similar points as below.
The securing method of screens is similar,which fit snugly and will not slip or slide once secured.
The screen design is similar
