Drilling fluid and equipment maintenance cost can decrease greatly when proper solids control practices are utilized. From a fluid control stand point it would be desirable in most cases to remove all drilled solids. Although this is possible, it would be cost prohibitive.

The goal of a solids control system is to achieve the balance between mechanical solids separation and dilution that will result in drill solids being maintained at an acceptable level with a minimum of cost.

Solid control system is a unit of removal solid from drilling fluid which is an essential parts for a completion drill site.  Solid control system  not only can save drilling cost bur also can effective protect the environment. How we efficiency use the solid control system to get the best effect.

drilling solid control system

To achieve effective solids control system, the following should be deployed:

1. Obtain an effective, dependable, and durable solids control system.
2. Ensure that the solids control system acquired is:
a. Hydraulically balanced
b. Is capable of making both a scalp cut and a fine cut.
c. Has sufficient drilling fluid mixing and re-circulating capacity.

3. Do not by pass the shale shaker or other solid control equipment while drilling.
4. Use the smallest mesh screen possible on the shale shaker. This will change from formation to formation and will require operators
to maintain a variety of screens on hand.
5. Maintain an adequate inventory of recommended spare parts and screens.
6. Certify and assign rig personnel to be responsible for equipment operation & maintenance.

a. Request equipment commissioning and training for OEM.

b. Discuss possible written training programs that may be available from OEM.

Drilling cuttings zero discharging management

⋅ Leave a Comment

DC Solid control have a new design of drilling cutting management system to meet government requirements to drill site and
environment.

Zero discharge of drilling mud” is generated relative to traditional drilling waste management mode. During the traditional drilling
process, mud pit is built at the drilling site for drilling waste management. That is, drilling waste is discharged to the mud pit at
ground level for next-stage treatment, or even directly buried. This traditional discharge mode causes serious pollution and great
harm to the environment and human life.

vertical cutting dryer

Advantages of zero discharging management system

1. Minimization of environmental risk
Drilling waste fluid treated by waste mud processing system realizes the” zero discharging” and eliminate the potential pollution
risk of drilling waste is situ curing,Which is not only keep drilling site clean, but also meet the requirements of environmental
protection.

2. Drilling fluid waste zero discharging system combined the “process treatment and “termination treatment” into one, and drill site
doesn’t need to dig mud pool, to keep the soil ecological security and environmental protection.

3. Drilling waste resource recovery
Moisture content of mud cake produced by solid and liquid separation can be controled within 20%, which is the inexpensive
ingredients for brickyard and ceramsite factory, also can be used as microbial soil to realize solid waste recycling.

What is water base drilling fluid

⋅ Leave a Comment

Water base drilling fluid is use the water as dispersion medium, it is a sol Suspension hybrid system. The major components are
water, clay, additive and all kinds of chemical treating agent. There are five stages of the base water drilling fluid, the nature
drilling fluid (1904-1921), fine dispersion drilling fluid (1921-1946), coarse dispersion drilling fluid (1946-1937), don’t spread
low solid phase drilling fluid （1966 until now).

water base drilling fluid

The water base drilling fluid is divided into;

1 The fresh water drilling fluid. The content of sodium chloride is less than 10mg/cm&sup3, the content of calcium ion is less than 0.12mg/cm³。
2 The saline drilling fluid ( seawater and salt water drilling fluid included). The content of sodium chloride is higher than
0.12mg/cm³.
3 The saturated salt water drilling fluid. It is saturated solution with a kind or various soluble salt.
4 The calcium treatment drilling fluid. The content of calcium ion is less than 0.12mg/cm&sup3.
5 The hybrid emulsion drilling fluid, it has the water base drilling fluid with 3%-40% emulsified oil.
6 The don’t disperse and low solid phase polymer drilling fluid, the contend of solid phase is less than 4%, it has the moderate
polymer.
7 The potassium base drilling fluid, the content of the potassium chloride is higher than 3%, from 1978, it was used in our country
oil field.
8 The polymer drilling fluid. The polymer as the main body, the ingredients is viscosity reducer, filtrate reducer, prevent collapse
agent, lubricant and all kinds of chemical treating agent. It is a new drilling fluid system developed in the 1980s.

Historical of drilling fluid

⋅ Leave a Comment

Drilling fluid was used in the mid-1800s in the cable tool( percussion) drilling to suspend the cuttings until bailed from the drilled hole. With the advent of rotary drilling in the water well-drilling industry.

Drilling fluid was well understood to cool the drill bit and to suspend drilled cuttings for removal from the wellbore.  Clay were being added to the drilling fluid by the 1890s and by the time spindletop was discovered in 1901. It was considered necessary to have suspended solids( clay) in the drilling fluid to support the walls of the borehole.

drilling fluid

These solids resulted from the disaggregation of formations penetrated by the drill bit. If the penetrated formations failed to yield sufficient clay in the drilling process, clay was mined on the surface from a nearby source and added to the drilling fluid. These were native mud created either by ” mud making formations” or, as mentioned, by adding specific materials from a surface source.

drilling mud

Drilling fluid was recirculated and water  added to maintain the best weight and viscosity for specific drilling conditions. Cuttings, or pieces of formation that were not dissolved by water, required removal from the drilling fluid to continue the drilling operation. Under the sole discretion of the driller or tool pusher, a system of pits and ditches was dug on-site to separate cuttings from the drilling fluid by gravity settling. This system included a ditch from the well, or possibly a bell nipple, settling pits, and a suction pit from which the “clean” mud was picked up by the mud pump and recirculated.
