1.Drilling Cementing truck usage and specification
Cementing truck is designed oil drilling, gas cycle, rinse the special vehicles, recycling equipment is important, it has many uses in the oil field development. Killing, cementing, it can be used to stir the grout, grout injection wells to in order to achieve the purpose of cementing the casing and the borehole wall; can be used to squeeze into the wax, fungicides, etc. When the oil wells to achieve sterilization , wax purpose; in underground operations, can be used to wash the wells, washed sand, wax, casing pressure test to find channeling, channeling seal, water shutoff, a cement plug for oil, low acid fracturing work.
Drilling Cementing truck models use more oil fields, its technical specifications in Table 1.
Table 1 Drilling Cementing truck Technical Specification

2.Cementing truck typical presentation
Cementing truck oilfields field use more, but the same principle, similar to the structure described below two common.
1. SNC-H300 type Cementing truck
SNC-H300 type Cementing truck machinery plant products Lanzhou, Jinan truck production JN choose a 150 Huanghe truck chassis, upload pump, gasoline engine, piston, with its structure shown in Figure 1.

Figure 1 SNC-H300 type Cementing truck Outline
1- cab; 2- table lamps; 3- vertical pumps; 4- gasoline engine; 5- horizontal pumps; 6- High Pressure manifolds frame; 7- tank; 8- funnel; 9- export
SNC-H300 type Cementing truck was in the 1970s began to put into use the products for oil wells within 2000m loop operations. Wagon gasoline engine with vertical triplex plunger pump is mainly used for mixing cement slurry, the scene because there is a fixed Cementing truck, and therefore this device has been removed; horizontal cylinder piston pump powered by a gasoline engine, which maximum displacement for 1.27m3 / min, the maximum pump pressure of 30MPa, washed sand, wash well, recycling and other operations are working with this pump.
2. SNC a 400 II type Cementing truck
SNC-400 type II Cementing truck is China National Petroleum Corporation Drilling Equipment Design Research Institute, Department of Space, Chengdu Engine Company manufactured products. Its shape shown in Figure 2, mainly by carrying cars, car engines, piston pumps, water pumps, console, measuring tank, High Pressure manifolds and other components.

Figure 2 SNC a 400Ⅱ type Cementing truck appearance
Visible, followed by installation of diesel automobile cab from the figure, piston pumps, water pumps, console, transmission and metering tank car station set up on both sides of the high-pressure pipe, Swivel joint and suction hoses.
SNC a 400Ⅱ type Cementing truck diesel engine through the clutch and cardan shaft the power transmitted to the gearbox, gearbox output shaft final drive piston through the work done by the pump passes through the secondary shaft coupling elastic.
Washed sand or recycling operations, the liquid piston pump suction line from the outside world, after the pressure pump into the well, to achieve the purpose of construction. When cementing, from metering tank or external pump suction line of water, after which the pressurized flow to the mixer through a mixer nozzle orifice, so as to form a vacuum and sucked dry cement, the inflow of water mixed into a slurry tank after grout Finally, the piston pump inhaled into the well. Cementing truck used in the underground work in progress, deep red sand, recycling and other operations.
