Abstract
The invention relates to a high-power hydraulic drive fracturing pump system which can meet the requirement of high flow and high pressure of a large fracturing pump and can simultaneously solve the problem that a fracturing truck set is difficult to arrange in a well site due to too many vehicles. The technical scheme of the high-power hydraulic drive fracturing pump system is as follows: fracturing pump cylinders and power cylinders are connected in series through bolts; plungers are mounted into the fracturing pump cylinders and the power cylinders; the fracturing pump cylinders are connected with a fracturing fluid inlet manifold and a fracturing fluid outlet manifold; liquid inlet and outlet ports of the power cylinders are connected with a reversing assembly, and the reversing assembly is connected with an oil inlet pipe and an oil return pipe; the oil inlet pipe is connected with hydraulic oil pumps, the oil return pipe is connected with a cooler inlet, and a cooler outlet is connected with a hydraulic line for an oil tank; the oil tank is connected with the hydraulic line for the oil tank; and the hydraulic oil pumps are connected with engines through transmission cases. According to the high-power hydraulic drive fracturing pump system, the power and the discharge capacity of a single fracturing pump truck can be improved by 4-7 times, and accordingly, the number of the fracturing pump trucks is reduced; and a cooler, the oil tank and the hydraulic oil pumps can be arranged outside a well, thereby facilitating the arrangement of the fracturing truck set in the well site.
Description
Technical field
The present invention relates to a kind of high power hydraulic for fracturing work and drive fracturing pump system.
Background technique
Fracturing unit truck group is comprised of fracturing unit truck, fracturing blender truck, measuring truck, manifold truck and sand-transport truck.Well fracturing, especially massive hydraulic fracturing, need the high pump pressure of large discharge capacity, and maximum pump discharge can reach 6m
3/ min, maximum pressure can reach 100MPa.Separate unit fracturing unit truck is difficult to satisfy the demand, so the integration of operation of many pressure break pump trucks of fracturing unit truck group needs, and a fracturing unit truck group conventionally need to configure 4～10 pressure break pump trucks and could meet need of work.For example, the HQ-2000 fracture acidizing unit that U.S. Halliburton Company manufactures and designs comprises 10 pressure break pump trucks, 1 fracturing blender truck, 2 manifold trucks and 1 measuring truck.Oil gas well site, especially well site, mountain area, vacant lot, well site area is often very limited, and fracturing unit truck group is arranged very crowded in well site, and between car group, manifold connects complexity, has increased greatly task difficulty.On the other hand, the ride of existing pressure break pump truck is arranged motor, transmission case, fracturing pump and cooler, and the little weight of bicycle discharge capacity is large, high to road capacity and slope requirement.
Shale gas exploitation requires very high to pressure break, its frac pressure can reach 100MPa, and fracturing fluid consumption can reach 10000m
3.Therefore shale gas exploitation has higher requirement to fracturing unit truck group power, and conventional fracturing unit truck group is difficult to meet, and conventionally needs the integration of operation of a plurality of fracturing unit truck group, and number of vehicles is often more than 10, and this has limited the development of shale gas exploitation to a great extent.
Summary of the invention
Object of the present invention: existing pressure break pump truck output is little in order to overcome, weight is large, to road capacity and the high shortcoming of slope requirement, and fracturing unit truck group pump truck is too much, manifold is complicated, in the shortcoming of well site confined space layout difficulty.
For achieving the above object, the technological scheme that the present invention takes is: a kind of high power hydraulic drives fracturing pump system, by hydraulic-pressure pump, transmission case, motor, fuel tank, cooler, oil inlet pipe, return tube, reversing assembly, power cylinder, plunger, pressure break pumping cylinder, fracturing fluid intake manifold, fracturing fluid outlet manifold, formed, its structure characteristic is: pressure break pumping cylinder and power cylinder series connection, and bolt connects pressure break pumping cylinder and power cylinder; Plunger is installed in pressure break pumping cylinder, and plunger end arranges piston and is installed in power cylinder; Pressure break pumping cylinder connects fracturing fluid intake manifold and fracturing fluid outlet manifold; Power cylinder enters liquid port and is connected to reversing assembly, and reversing assembly connects oil inlet pipe and return tube; Oil inlet pipe is connected to hydraulic-pressure pump, and return tube is connected to cooler entrance, and cooler outlet is connected with hydraulic line with fuel tank; Fuel tank is connected with hydraulic line with hydraulic-pressure pump; Hydraulic-pressure pump is connected with motor by transmission case.
The beneficial effect that the present invention has is: (1) pressure break pumping cylinder, power cylinder, hydraulic pressure reversing assembly boundary dimension are little, can be arranged on separate unit pump truck, separate unit pump truck can meet or exceed pressure and the flow that existing a set of fracturing unit truck group can provide, and has reduced greatly in well site pressure break pump truck quantity and has been connected manifold; (2) pressure break pumping cylinder and power cylinder effective travel can be according to the designs of pump truck chassis length, and stroke can reach 2.5m, has reduced greatly power cylinder commutating frequency, extends pump valve case and hydraulic unit life-span, reduces flow pulsation frequency; (3) many simultaneous firings, drive many hydraulic-pressure pump parallel operations, and total output is designed to the power that a set of pressure break pump truck group needs, and meets massive hydraulic fracturing requirement; (4) designing car carries cooler, concentrated cooling to hydraulic oil, simplification system; (5) motor and hydraulic-pressure pump can be arranged on a chassis or on many chassis, power car can be arranged on beyond well site, between pressure break pump truck and power car, by hydraulic line, be connected, the vehicle that carries fuel tank, cooler can be arranged on beyond well site equally, can effectively improve like this situation of vehicle congestion in well site.
