Recycle the drilling mud that lubricate the drilling bits.

The drilling mud solids control system is for filter away danger solids phase that contain in the drilling mud and reuse the needed solid phase.  The task is to keep drilling fluids in stable performance status.  There are several machinery that will need to perform the tasks.

The result of consist performance of drilling mud is avoid the blocking and damage of the oil and gas channel. It reduce the well drilling torque and friction drag and reduce the pressure oscillation of the annular air suction.  It also increase the velocity of the well drilling, extend life of the drill bit, reduce wear of the equipment.

drilling mud system

There are  five steps of filtering process that require five solids control machinery that will do  filter screening, degassing the mud, desanding the mud, desilting the mud, centrifuge force separation and demand of weighting up mud. The consist work flow between every solids control equipment use in the whole system is very important.   Level one to five level of output of the mud should be matched each other and the interval of separation size should be appropriate and have a certain overlap.  The result of the smaller solids which are not filter by the upper can be filter in the next controlled level.

With the development of well drilling technology, mud mixing system plays an important role in drilling operation. The various kinds of solids control systems function at the same time. Regardless the different kind of the solids control system, it’s basic function will not changed. It is depend on organic combination of mechanical removal equipments, drilling fluid mud tanks and other auxiliary equipments to accomplish the basic function:  Recycle the drilling mud that lubricate the drilling bits

Concept: The drilling mud cleaning cycle is to remove the harmful solid debris, reserve the clean drilling mud to meet the demand of drilling mud spec under the drilling process. Drilling waste management system is a general term of all drilling fluid solids control equipments used in the drilling process.

 

Function: To prevent the oil-gas well from clogging, breaking, and decrease the drilling torque and friction resistance, reduce the pressure fluctuations of the hollow suction, increase the drilling speed, extend the drilling head life, and reduce wear and tear of the equipments. Methods: The common methods are mixture-thin methods, swap methods, machine methods and additive-chemical methods. Machine method is by using screening, centrifugal separation and gravity separation to separate the solid phase according to the different size and density, therefore, to control the solid phase in the drilling mud.

 

1 The technical process of the mud cleaning system and the combination of the mud cleaning equipment.

The technical process of complete group of mud cleaning system should meet the specification of five level solid phase control (shale shaker screening, degassing, desanding, desilting, centrifuge) and the provoke of mud. The merger of each solid control equipment is very important, the through out  of one to five level of mud cleaning equipment should each corresponding, and the spacing of the proper distance were is appropriate.  To have certain overlap during the cleaning process, make the smaller particles of the processing incomplete in the up one had been disposed in the next solid control equipment.

 

2 Drilling mud cleaning cycle

The mud back from the opening of well through the pipeline and conveyed the drilling mud to the  shale shaker. The first phase of cleaning completed by shale shaker, then entered the mud tank, the mud flowed from the mud tank through the tank slot into the desander and desilter (if detect the exits of gas , vacuum degasser will process the gas) the mud after processing of the centrifugal steps and through the tank slot enters the inhalation cabin.  The cleaned mud then will reuse for lubricate and cooling the drill bit.

LiaoHe Oilfield, a CNPC organization, which can be the greatest production base for thickened oil and higher pour point oil in China has already procured 5 unit complete mud cleaning system from GN. The newest ZJ50 rig mud cleaning program has been presently operating nicely about the jobsite soon straight away just after our technicist creating the commissioning.

15A

The crucial equipments list for this 6-Tank approach beneath:

1. three units Shale Shaker each and every capacity of 140m3/hr

two. 1 unit Vaccum Degasser GNCQ360 wich eliminate the reduce in gas from the drilling mud to boost the efficiency of transfer pump.

three. Desander and Desilter just about every single for 1

4. 1 unit Higher Speed Decanter Centrifuge GNLW363

5. Agitators to stop the drilling mud sedimentation

6. Centrifugal Pump for transfer mud internal tank and charge to mud pump.

7. This ZJ50 rig mud cleaning system also equiped with poor boy degasser to stop blowout.

Concentrate on higher level domestic marketplace spot place and International marketplace location, GN generally adheres great 1st, Credit priority. By preserving this principle, GN established lengthy term organization relation with principal oilfield in China and at the moment exported to virtually 60 nations. Collectively using the GN new facility beginning production, welcome clientele household and abroad come for going to and company negotiation.

Diamond drilling

Diamond drilling is a kind of drilling , same with other kind of drilling to use mud .  There are some different requests with oil drilling and HDD drilling . Firsly , it’s capacity is much smaller . Secondly it’ s request for mud is not very strict .

Mud Cleanig Equipments for diamond drilling

Mud cleaning equipments is the most effictive stype of processing drilling mud . Some requires a shaker some not  . For a 60 cubic meters per hour mud system , one mud cleaner with 1X8″ desander cone & 4X4″ desilter cone  will be availeble . Yes for different of mud cleaning system , we will need to choose different equipments. Continue reading »

Horizontal Directional Drilling (HDD) uses a drilling rig on the surface to install a drill pipe in a shallow underground arc. The drilling rig bores a pilot hole that’s filled with fluid and then uses a swiveling reamer to enlarge the hole to the final sewer pipe size. Sewer pipe is then pulled through the hole. Directional drilling often needs a large staging area so the pipe can be lined up before it’s pulled into the hole.

Procedure of HDD
