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.
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
1, First purification
Ie mud treatment at the shaker. Preparation of a good drilling fluid under the action of the pump into the bottom of the well, and carry drilling cuttings back to the surface through the wellhead elevated tube into the mud shaker, the drilling fluid screening out large debris.
2, Second purification
When drilling a gas dip when, through the role of the vacuum degasser will purge gas drilling fluid, thereby restoring the fluid density, fluid viscosity stable.
3, third purification
Two purified fluid supply pump enters through desander Desander, drilling fluid 40 - 60μm or more tiny harmful solid phase is separated desander li.
4, Fourth purification
Three purified by drilling into the supply pump desilter , drilling fluid 15 - 40μm above the tiny harmful solid phase desilter li be isolated.
5, Fifth purification
Four purified by centrifuge feed pump drilling fluid into the centrifuge, the centrifuge will be drilling in 5 - 15μm tiny particles separated.
Desanderand Desilter: Desander desilter are made with a hydrocyclone and a
cyclone underflow handling and recycling of drilling fluids shale shaker small
fine mesh composed. Drilling desander 30-90μm used to remove solid particles;
desilter used to remove the 10-30μm solid particles. Carve cyclone and the
cyclone particle size D50 is not only related to the size of the structure, but
also with the drilling fluid density, density and pressure of the liquid inlet.Drilling
desander shale shaker should be used as the second stage solid phase after
removal of some equipment, and desilter should be used as the third stage
solid-phase removal equipment.
In order to meet the requirements of handling all of
the drilling fluid , drilling fluid and desilter desander must be made up of
several components cyclone cone . In order to ensure normal operation cyclone .
Inlet pressure must be maintained at 0.25 --- 0.35MPa this range. Desilter
swirl cone because many long pipeline , the inlet pressure should be whichever
is greater ; drilling desander less due to cyclone cones , pipe sections, the
inlet pressure is due , whichever is smaller . Inlet pressure depends on the
size drilling sand pump matching is reasonable, therefore drilling sand pump
selection is critical, usually 40mH2O drilling sand pump head around with the
drilling fluid displacement and division desander mud is equal to the amount of
the calibration process , you can meet the requirements.
Meanwhile, in the
selection of drilling fluids and desilter desander must take into consideration
the maximum displacement of drilling pump , with its reach a reasonable match .
Both devices use the time , no strict restrictions , usually in shallow
stratigraphic drilling and soft formations , drilling cuttings large particles
content is high, the two must be used simultaneously ; at drilling depth strata
and hard strata , if with fine mesh shaker can be used directly in addition to
handle drilling mud , which have little impact on the quality of drilling fluid
purification , and very
economical.

Centrifugal pump is a sub-class of dynamic axisymmetric work-absorbing turbomachinery. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits.
Common uses include water, sewage, petroleum and petrochemical pumping. The reverse function of the centrifugal pumps is a water turbine converting potential energy of water pressure into mechanical rotational energy.
Following some pictures of our centrifugal pumps.
