Mobile autonomous pump installation with system of purification of drilling mud fluidInstallation pump autonomous with system of purification of UN-16/20 drilling mud fluid is intended for supply of drilling mud fluid under pressure in a well for the purpose of the drive of the bottomhole engine and ensuring circulation, and also for purification of solution in the course of drilling.
Installation pump autonomous represents a mobile complex of processing equipment which provides giving in a well of drilling mud fluid under pressure and its subsequent cleaning of vyburenny breed.
Installation is executed from conditions of convenience of transportation in the form of two blocks in which the processing equipment is mounted on a platform of semi-trailers heavy trucks and it is closed by soft awning shelter.
Both blocks of pump installation settle down on the platform at the mouth of a well.
The block of cleaning will connect the following technological communications:
- with a funnel on the mouth of a well — the metal pipeline or a sleeve with a bias corner towards the block not less than 15 °;
- with the pump block a rubber sleeve on the line of absorption of the retaining pump and two pipelines — on the line of a starting latch and the line of dumping from the safety valve of the boring pump.
The pump block will connect to the mouth of a well a sleeve or the pipeline. Both blocks have to be installed on calculations before filling of capacities and pipelines with drilling mud fluid.

The description of components of installation, their appointment and work are given below in technological sequence.
The block of purification of drilling mud fluid consists of the following components:
- trekhsektsiopny capacity;
- hydroclone peskootdelitel;
- slurry pump;
- float-operated valve;
- the pipeline is pressure head;
- the pipeline which is soaking up;
- recuperative air heater;
- semi-trailer heavy truck;
- awning shelter.
The block of cleaning carries out function of reception of drilling mud fluid from a well and its cleaning of vyburenny breed.
Three-section capacity consists of compartments, two of which have height of 0,9 m and the volume of 4,5 m everyone, and the third — height of 1,6 m and the volume of 9 m3. The capacity design with unequal height compartments is accepted proceeding from technological features of process of purification of solution and allows to combine rather small height of a rastvorosliv with an opportunity to have a necessary reserve of drilling mud fluid on a case of unforeseen complications in the course of drilling. Two identical compartments are divided by an overflow partition with a shiberny lock, and the third high compartment is connected to the next compartment the overflow pipeline with the float-operated valve and the perepuskny pipeline with the shiberny gate.
Steps of purification of drilling mud fluid
1. The vibrosieve like SV-1L-02 is established on technological capacity over the first compartment and intended for purification of drilling mud fluid of particles of vyburenny breed not less than 2,0 mm in size. It is the first step of purification of drilling mud fluid. The vibrosieve like SV-1 L-02 is recommended by the manufacturer for application in circulating systems of installations for workover and at kickoff of the second trunks. At the request of the Customer the block of cleaning can be completed vibrositompozvolyayushchy to delete smaller particles of vyburenny breed.
The solution purified on a vibrosieve flows down in the first compartment of technological capacity, and slime on an inclined tray is removed out of block limits where is going in containers with the subsequent export to the ground for utilization. Drilling mud fluid, having filled the first compartment to the level of an overflow partition, begins to flow in the second compartment.
2. The second step of cleaning is the hydroclone peskootdelitel who is established over the second compartment of technological capacity. Drilling mud fluid gets from the second compartment of capacity the slurry pump by means of the soaking-up pipeline and on the pressure head pipeline moves in an entrance branch pipe of a hydroclone under pressure of 0,2-0,3 MPas. In a hydroclone there is an office of particles of slime not less than 0,06 mm in size. The purified solution on the pipeline merges in the third compartment of technological capacity. Unloading of slime is made through a peskovy nozzle of a hydroclone and a removable tray on a folding tray of a vibrosieve from where slime is dumped in the container-shlamosboriik. On the first models of installations the peskootdelitel of PG-60 was applied (pr-in. Pleasant). If necessary installation of a peskootdelitel of the slime not less than 0,04 mm in size providing office of particles is possible.
The slurry pump is intended for supply of the drilling mud fluid which passed cleaning on a vibrosieve in hydroclone a peskootdelitel. The pump is installed on a semi-trailer platform. The pump centrifugal with a lateral supply of the pumped-over liquid. Its main details are made of wearproof and corrosion-resistant materials. The taking-away branch pipe is directed vertically up. Productivity of the pump is accepted slightly more, than it is required for work of installation and if necessary, it can be adjusted by means of a latch on the pressure head pipeline. After a latch on pressure head the truboprovodeshlamovy pump the manometer is installed.
Around the pump the passes sufficient for implementation of service and repair are provided. The platform on which the pump is installed is supplied with protections, and for rise on it there is a ladder.
On the first installations the widespread slurry pump 6Sh8-2 is installed. Much more reliable pump having hard-alloy omental knot and which is not inferior according to the characteristics to the best world samples is at the moment fulfilled.
The float-operated valve is intended for prevention of overflow of the second compartment of technological capacity and environment protection against hit in it drilling mud fluid.
The float-operated valve consists of a basket and the float located in it from polyurethane foam or other material with specific weight there is less unit. The float freely lies at the bottom of a basket. In its center there is an opening which the vertical directing probe welded in the center of a bottom of a basket enters. The basket is fixed in the top part of the second compartment of technological capacity under withdrawal of the overflow pipeline.
At the same time the float has to be located on an axis of a vertical site of the overflow pipeline.
The valve works as follows: when filling capacity with drilling mud fluid the float, under the influence of the pushing-out force, emerges and nestles on an end face of an overflow pipe, blocking its section. Thus, the solution overflow from the third compartment in the second stops. As soon as solution level in the second compartment goes down as a result of operation of the slurry pump, the float under the influence of a body weight falls to a starting position, opening the section of a pipe through passage, and solution is again poured from the third compartment in the second before its filling and closing of the valve.
The recuperative RV-40(zh) air heater is intended for heating of three-section capacity and the power plant of the pump block before start in a cold season. As fuel diesel fuel is used.
Switching of supply of hot air is made by the shiber established on an air duct.
