Drilling waste management system for CBM

⋅ Leave a Comment

The process of drilling and completing coalbed methane (CBM) wells is similar to wells in conventional reservoirs. Coring, however,
can pose special challenges.

The first step in creating a drilling program for a CBM well involves gathering information about existing wells in a given area.
These data include:

Reservoir depths and pressures
Drilling histories
Environmental considerations

What is the main process of drilling fluid circulation

⋅ Leave a Comment

Drilling fluid circulation in the drilling field mainly includes dosing process, weighting process, supply process and others. Now let me introduce how it works to complete the whole circulation.

Drilling fluid dosing process

Drilling fluid dosing process is the auxiliary process of the drilling fluid solid control. The main function of it is removing the harmful solid phase by adding chemical agent to drilling fluid and chemical precipitation principle; Also can improve drilling fluid property, drill rig stability and drilling speed.

Drilling fluid weighting process

Drillingg fluid weighting process is the auxiliary process of drilling fluid solid control system. The main function of weighting process is increasing drilling fluid density and keep well wall stability according to add barite to drilling fluid to meet the requirements of drilling work to drilling fluid properity.

Weighting pump can directly inhale all tanks drilling fluid by weighting pump suction pipeline, except can’t inhale shale shaker tank drilling fluid. The drilling fluid after weighted by weighting hopper deliveried to all tanks by weighting discharge pipeline except for setting tank.

solid control system

Drilling fluid supply process

Drilling fluid supply process is the auxiliary process of drilling fluid solid control system. The main function of mud supply process is guarantee well wall stability according to supply drilling fluid to well hole when lifting drill tools.

The drilling fluid in trip tank is deliveried to wellhead through discharge pipeline by trip pump. The drilling fluid returned from wellhead enter into trip tank controled by distributor valves. Drilling fluid in reserve tank also can be transported to trip tank by weighting pump pipeline.

Other process

The mud out from well head enter into distributer through pipeline, which can be directly discharged to waste pit by distributer control valves. Also can flow into setting tank through shale shaker or flow any thanks by aqueduct( adjusting flashboard).

Process of mud circulating system

⋅ Leave a Comment

Mud circulating system is the the equipment and system used on a drilling or workover rig pump drilling mud into and out of a well. On a drilling rig, the drilling mud is sucked out of the mud tanks where it is stored by the suction line that goes to the mud pumps or hogs.

The mud then flows through the discharge or mud line; down the rotary hose, swivel, kelly, drillpipe, and drill collars; and out the nozzle on the drill bit, onto the bottom of the well.

solid control system

The mud picks up well cuttings and then flows up the annulus between the wellbore and the drill pipe, through the blowout preventers to the surface. On the surface, the drilling mud flows through the mud return line to the solids-control equipment, which includes the shale shaker, desander, desilters and degassers. It then flows back into the mud tanks to be recirculated.

Drilling rig circulating equipment used to remove fine-grained well cuttings from weighed drilling fluid using desilting hydrocyclones and vibrating very-fine mesh screens without excessive loss of barite and fluid. The intake is after the shale shaker. The hydrocyclone underflow flows onto the screens. Solids are disposed of in the reserve or waste pit. The fluid is discharged into the mud tank. General term for the shale shakers, desanders, desilters, and settling tanks used to remove solids from circulating drilling mud on a drilling rig.

CBM drilling mud cleaning system

⋅ Leave a Comment

Coal bed methane is an important and fast growing resource in Alberta, which is short for CBM. This new type of drilling requires adaptive techniques, technology and a wealth of experience to properly tap.

Basic principles

Methane adsorbed into a solid coal matrix (coal macerals) will be released if the coal seam is depressurised. Methane may be extracted by drilling wells into the coal seam. The goal is to decrease the water pressure by pumping water from the well. The decrease in pressure allows methane to desorb from the coal and flow as a gas up the well to the surface. Methane is then compressed and piped to market.

cbm

The objective is to avoid putting methane into the water line, but allow it to flow up the backside of the well (casing) to the compressor station. If the water level is pumped too low during dewatering, methane may travel up the tubing into the water line causing the well to become “gassy”. Although methane may be recovered in a water-gas separator at the surface, pumping water and gas is inefficient and can cause pump wear and breakdown.

CBM cleaning system

As well as petroleum drilling, CBM drilling which also use drilling mud cleaning system with some differences based on gas drilling. Drilling mud cleaning system industry has turned to be a very important industry followed by the enery resources and environment request. DC Solids Control has turned to be one of the leading manufacturer for drilling mud cleaning system focused on CBM.

Development direction of mud solid phase system

⋅ Leave a Comment

Simplification and optimize of solid control system:

Field experiments showed that, adopts high efficiency drilling fluid shale shaker + frequency conversion centrifuge component the new type two stage solid control system, can omit desander and desilter, the energy saving effect is obvious. Also can adopts classification filtration technology, can completely change existing solids control equipment, also can leave out desander and desilter. Using vacuum filtration type even can leave out drilling fluid shale shaker, greatly simplify solid control system, reduce drilling team electric generator load, optimize mud tank allocation, reduce the quantity of mud tank and increase the quantity of reserve tank, so can obvious improve solid control efficiency, shorten treating capacity times and increase drilling safety.

solid control system

Firstly degassing, then screening:

At the present, the drilling fluid returned from well mouth are all processed by shale shaker, when screening, mass of gas overflow, it not only increase the dangerousness of drilling fluid shale shaker, but also serious damage operating personnel health. So specially designed the degassing device put in the primary place, firstly, degassing treatment of the returned drilling fluid from well mouth which can decrease drilling fluid gas content, reduce the harmful gas to human body and drilling accident.

The part process changed into whole process:

Drilling fluid shale shaker is the exclusive solid control have the whole process to drilling fluid, it is very important to improve drilling fluid solid phase control level. Because of the treating capacity of desander, desilter and centrifuge is limited, the follow up solid control equipment is only the part operation, in addition, will have part drilling fluid directly enter into subordinate cabin through drilling fluid tank which don’t get processing.

Drilling field only increase drilling fluid treating cycle index to improve solid control quality. Increase circulating times can improve the treated drilling fluid ratio, but decrease treating efficiency, waste large energy, so the solid control efficiency is very low.

By changing to other treatment type, if we use supper fine drilling fluid shale shaker or new type filtration machine can increase treating capacity and improve machine drilling speed.
