Novel ultra-large-displacement ultrahigh-pressure well cementing equipment

The invention discloses novel ultra-large-displacement ultrahigh-pressure well cementing equipment. The novel ultra-large-displacement ultrahigh-pressure well cementing equipment comprises a loading carrier. A hydraulic system, a power transmission system, a metering tank, an electrical system, an air path system, a control system, an operating platform, a plunger pump, a clean water manifold, a mud manifold, a high-pressure manifold, a mixing system and an ash feeding manifold are mounted on the loading carrier, wherein the plunger pump is a five-cylinder plunger pump. The five-cylinder plunger pump is adopted to increase the pressure and displacement of the well cementing equipment, and the requirements of high pressure and large displacement are met; slurry mixing is carried out by double mixing devices, the mixing efficiency is improved, the stability of the slurry mixing density is improved, and the requirement of long-time uninterrupted operation is guaranteed; a mixing system pipeline is optimized, multiple sets of mixing systems are integrated on one slurry mixing tank, and the stability of the equipment is improved; and the clean water manifold is optimized, so that watersupply requirements of the multiple mixing devices can also be met at the same time by using one injection pump, and the requirement of large displacement is met.

A fracturing sand mixed car

The invention provides a fracturing blender truck. The fracturing blender truck comprises a chassis and a sand blending device arranged above the chassis. The sand blending device comprises a sand blender provided with a fracturing sand inlet, a base fluid inlet and a fracturing fluid outlet, and a closed-type mixing pump serves as the sand blender. The fracturing blender truck further comprises an overturning support and a power system, wherein the overturning support arranged on the chassis is capable of achieving reciprocating rotation and used for bearing the sand blending device, and the power system arranged on the chassis is connected with the overturning support and drives the overturning support to rotate to enable a base of the closed-type mixing pump to be capable of contacting with the ground. The fracturing blender truck has the advantages that the closed-type mixing pump serves as the sand blender, and the rotatable overturning support is used for bearing the sand blending device to enable the base of the closed-type mixing pump to be capable of contacting with the ground, so that suction capacity of the closed-type mixing pump is improved, delivery capacity of the closed-type mixing pump is increased, delivery capacity of the fracturing blender truck is increased without changing the occupied area of the fracturing blender truck, and the requirements on large-scale fracturing operation can be met.

A kind of fracturing sand mixer

The invention provides a fracturing blender truck. The fracturing blender truck comprises a chassis, a sand blending device, a four-connecting-rod mechanism and a power system. The sand blending device is arranged above the chassis and provided with a sand blender, and a closed-type mixing pump serves as the sand blender. The four-connecting-rod mechanism is capable of driving the sand blending device to move to enable a base of the closed-type mixing pump to contact with the ground, a first connecting rod and a third connecting rod of the four-connecting-rod mechanism are arranged on the chassis rotatably, and the sand blending device is arranged on a second connecting rod of the four-connecting-rod mechanism. The power system arranged on the chassis is connected with the first connecting rod and drives the four-connecting-rod mechanism to rotate to enable the closed-type mixing pump to contact with the ground. The fracturing blender truck has the advantages that the closed-type mixing pump serves as the sand blender, and the second connecting rod of the four-connecting-rod mechanism is used for bearing the sand blending device to enable the base of the closed-type mixing pump to be capable of contacting with the ground, so that the height of the closed-type mixing pump is decreased, suction capacity of the closed-type mixing pump is improved, a great quantity of fracturing fluid can be guided out, delivery capacity of the fracturing blender truck is increased, and the requirements on large-scale fracturing operation can be met.

Fracturing transmission and high-pressure discharging system

The invention relates to a fracturing transmission and high-pressure discharging system. The fracturing transmission and high-pressure discharging system comprises a chassis and is characterized in that a high-power engine, a transfer case, a plurality of variable displacement plunger pumps and a double-acting fracturing pump are arranged on the chassis, the output end of the high-power engine is connected with the input end of the transfer case, the output end of the transfer case comprises a plurality of power take-off ports, and each power take-off port is connected with one variable displacement plunger pump; the variable displacement plunger pumps drive the double-acting fracturing pump through a hydraulic system. The fracturing transmission and high-pressure discharging system further comprises a system radiator and a heat dissipation plunger pump used for driving the system radiator, and the heat dissipation plunger pump is connected with one power take-off port of the transfer case. The power take-off ports of the transfer case and the variable displacement plunger pumps are arranged annularly. The fracturing transmission and high-pressure discharging system has the advantages that hydraulic driving replaces mechanical transmission, and working vibration is reduced; the layout space of a whole vehicle is saved, and meanwhile, operating efficiency and the stability of the whole vehicle are improved.
