Improved the recycling of drilling fluid system

Drilling centrifugal pump in solid control system, sand pump is used for the drilling fluids Desander , in addition to mud , mud cleaners and other equipment for the material, the transmission medium is circulating with the solid phase drilling fluids . Existing drilling sand pump shaft seal using a simple mechanical seals , often resulting in the string into the drilling fluids sand pump bearings ( sealed ), of which the drilling fluid contains large amounts of solid particles . Thus making drilling centrifugal pump bearings quickly damaged , causing many to abandon drilling drilling crew and desilter desander etc. , only shale shaker , a serious deterioration in the drilling conditions . 

For drilling fluid seal problems Xi'an Brightway Energy Machinery Co., Ltd. developed a new type of sand pump seal, mechanical seal structure using the new theory, the structure of the active life than more than doubled .

 Drilling pump in the drilling solids control system is the most important hydraulic devices. However, the existing drilling pump significantly larger , emphasis , and the pump piston and cylinder wear is very serious, is the main wearing parts of the pump. The reason is mainly for two reasons : First, the structural design of drilling pump is mainly imitation , not using modern design methods , resulting in a significantly larger drilling pump structure ; Second, the solids content of the drilling fluid ones, mainly due to serious friction liner wear - especially barite drilling fluid pump piston causes.

To do this , you should use good sealing effect , long life drilling sand pump new seal structure to extend the life of sand pump , better play drilling solids control equipment performance , improve drilling efficiency. 

Solids Control Structure and working principle

Solid control system consists of a set of storage tanks and drilling fluid solids control drilling fluid used to remove harmful solid phase composed of a group of devices, storage tanks and solid control of drilling fluid circulation tank with reserve tank is divided into two parts. Ground drilling fluid circulating tank as part of a cycle, the tank surface mounted shaker, vacuum degasser, desander desilter, centrifuges and other equipment for the purification of fluids. Reserve tank is based on the need for preparation of drilling conditions different properties of the drilling fluid, or storage may be used for different drilling conditions of the drilling fluid.


Drilling fluid purification process in the system

Function of Drilling Solid Control equipments

Solids control procedures are often ignored in many oil & gas drilling projects. Many people do not understand very well the basic principles of drilling fluids solids control. They persist that drilled solids are evil & insidious. In a short term, drilled solids increasing generally does not reveal their economic impact immediately, and the detrimental effects are also not immediately obvious on the drilling rig. But in a long term, increasing of drilled solids would generate many problems on drilling rigs. So drilled solids need to be removed at the surface by solids control equipment, such as shale shaker, mud cleaner, centrifuge, etc. to reduce the risk.

Drilled solids damage reservoirs, increasing drilling cost, and also create large drilling processing disposal cost. To drill an oil or gas well fast, safely, and under budget, it is necessary to remove the drilled solids which not only include drilling cuttings, but also sloughs that drop from the wall of borehole. If these drilled solids can not be removed timely, they would cause many problems, including:
● Filtrate damage to formation
● Drilling rate limits
● Drilling string stuck
● Borehole Problem
● Lost circulation problem
● Direct drilling fluid cost
● Increasing disposal cost

Decreasing drilled solids is analogous to buying an insurance to an event that will not happen to drilling rig. Nobody wish these above problems happen to any drilling project, but they do exist, and they are real. The effects of drilled solids on economics of drilling a well is subtle, and increasing of drilled solids does not result in a disaster immediately on a drilling rig. When the drill bit ceases to work and torque increases, driller know that it is time to pull the bit. But when the drilled solids increases, the detrimental effects are not apparent immediately.

That is why the drilling fluids are used to bring drilled solids to the surface, and removed timely by the solids control equipment, such as shale shaker, desander, desilter, mud cleaner, centrifuge, etc. But not all the solids are removed, and it is also impossible to remove all the solids. Some solids that smaller than the shaker screen openings would stay in drilling fluids, and other additive agents, such as barite, clay, etc. are also essential to adjust drilling fluids property.

BW Solid Control for Coal Bed Methane (CBM) Drilling

Coal bed methane(CBM) is a form of natural gas that is extracted from coal bed seams. Sometimes it is called coal bed methane, or coal bed gas, or coal mine methane (CMM). The primary energy source of CBM is a substance called methane (CH4), which is colourless, tasteless, non-toxic & flammable, making coal bed methane available to be used in all natural gas appliances in our home and also commercial applications such as electricity generation. In recent decades it has become an important source of energy in United States, Canada, etc. In Australiahas where has rich deposits, it is known as coal seam gas (CSG).

BW Solid Control System for CBM Drilling

CBM is generated either from a biological process as a result of microbial action or from a thermal process as a result of increasing heat with depth of the coal. It is hold loosely in the coal bed seams by the water & underground pressure. As the main content of CBM, methane has very low solubility to water. To explore CBM, the underground water must need to be removed by pumping, which would reduce the pressure on gas and allow it to detach from the coal bed seam. Thus, CBM that hold in the coal bed seams can be released to the surface with the flowing of water, then CBM are separated from water and collected by special device at the surface.

Coalbed methane is usually very shallow, mainly around 1000 meters. That is why the drilling rigs for CBM are normally for 1000 to 2000 meters. The type & density of drilling fluids for CBM development must be designed and fixed according to the formation pressure, and also need to allocate appropriate solids control equipment, such as shale shaker, mud cleaner, centrifuge, etc. For surface well & intermediate section drilling, drilling medium should refer to the conventional CBM drilling medium optimization principle, while for horizontal well drilling, it should use superior drilling medium, non-clay drilling fluids, fresh water, gas, such as nitrogen, air, etc. & also froams to avoid drilling medium to harm the coal bed seams.

BW Decanter Centrifuge Working Principle and Function

Decanter centrifuge is the important phase cleaning equipment in a complete solids control system to separate fine solids. It is the most high technology products among all solids control equipments.

Centrifuge Working Principle

A centrifuge works on the principle of accelerated settling. By imparting addition “G” forces to the content of a centrifuge, solids (in a solids laden fluid) will settle much quicker. To understand how a decanting centrifuge works after desilter , first look at a simple sedimentation vessel.
Solids in this fluid will settle to the bottom of the vessel over a period of time. One way to speed the process of settling is to reduce the height of the vessel so the solids do not have as far to drop. If a specific volume is required, the vessels dimensions can be lengthened or widened . Depending on the rheological properties of the fluid and the size and density of the solids, settling time can still prove quite slow. 
Centrifuge Functions
A decanting centrifuge consists of a conical, horizontal steel bowl that rotates at high speed using a double screw type conveyor. The conveyor rotates in the same direction as the outer bowl but at a slightly slower speed. 
Functions including:
1) De-water hydrocyclone underflow;
2) Remove drilled solids from the active mud system
3) Control rheological properties by removing colloidal particles in weighted drilling fluids.

A decanting centrifuge is so named because it decants or removes free liquid from separated solids. It consists of a conveying screw inside a rotating bowl By exerting increased G-force on the drilling fluid, the particles are accelerated and settle on the outside of the bowl The free liquid pool is removed and the solids are pushed away and discharged from the bowl.
