Description
Technical field
The utility model relates to the Oil/gas Well large-scale industrialized fracturing work of especially unconventional shale oil gas well field, relates in particular to a kind of batch production scale pressure break band from the novel manifold truck/sled of supercharging perfusion.
Background technology
Along with the continuous increase of social development demand for energy, energy ore reserve routinely reduce day by day, and yield more and more can not meet the demand of social development.As the important supplement of conventional energy resource, the unconventional energy resource such as shale gas progress into people's the visual field.Under the leading of shale gas exploitation form, the unconventional energy resource industries such as Chinese shale gas have started to walk, and along with the increasing of policy support dynamics, will there will be large-scale development subsequently abroad, and petroleum equipment market will be more flourishing.The unconventional energy resource kits such as shale gas are containing exploring, develop, produce three large links, and wherein, the demand meeting showed increased of development and production link to equipment, has higher requirement to the function of equipment and performance.Develop energy, fracturing technology is a ripe yield-increasing technology of extensive use, is an important process measure of frscturing, intensified injection of wells, is also the important means that improves recovery ratio.Current fracturing technique becomes again the unconventional energy resource such as shale gas and develops basic necessary Completion Techniques, and the small displacement of Oil/gas Well, low-pressure, small-scale type fracturing technology have been not suitable with the exploitation of the unconventional Oil/gas Wells such as shale gas routinely, must adopt large-scale industrialized pressure break means.Large-scale industrialized pressure break equipment needed thereby is many, scene is large, but due to intend exploitation oil reservoir many places in mountain region, the region of hills, basin and other ambient conditions difficulty, position, well site select and road construction all more difficult, often cause and need to carry out at narrow and small well site area the layout arrangement of equipment.Equipment is arranged with well site physical features, science is arranged difficulty, be between equipment and equipment room, equipment and well head, to have formed very long feed-line, cause the Pressure Drop of fluid to increase, and the discharge pressure of fracturing blender truck sand pump lower (being generally 0.4 ~ 0.6MPa), after the pressure loss, can not, fully for fracturing unit truck provides fracturing fluid, can make fracturing unit truck occur suction phenomenon.
The at present effect of on-the-spot manifold truck mesolow manifold used: the input port of the low-pressure manifold of a plurality of delivery outlets (4 ") of fracturing blender truck and manifold truck (4 ") are connected, again by the input port of the delivery outlet of the low-pressure manifold of manifold truck and every fracturing unit truck (4 ") are connected; the fracturing fluid that fracturing blender truck is discharged like this converges to low-pressure manifold main pipeline (8 " or 10 "); and then divide row to each fracturing unit truck by main pipeline; in the middle of just having played fracturing blender truck and fracturing unit truck, be connected transitional function, can not play secondary booster effect; Simultaneously due to several places 90 degree corners in manifold, fracturing fluid during by manifold resistance can increase, when fracturing fluid is flowed through manifold like this, increased on the contrary the Pressure Drop of fluid.
The fracturing fluid that fracturing blender truck is discharged is through feed-line, manifold truck (sled) low-pressure manifold, while arriving fracturing unit truck intake (upper tank), first be by small pipeline (4 ") enter low-pressure manifold main pipeline (8 " or 10 "); then by the main pipeline of low-pressure manifold, enter small pipeline again; flow into again fracturing pump intake; like this owing to going out the repeatedly variation of inlet pipe road section area; also can produce certain flow resistance, thereby manifold has further increased again the Pressure Drop of fluid.
The effect of high pressure pipe joint is: the high-pressure outlet of each fracturing unit truck is connected respectively with each input port of high pressure pipe joint, then by the delivery outlet of high pressure pipe joint with enter well lines and be connected.Flow process is that the high pressure fracture liquid that each fracturing unit truck is discharged is flowed to high pressure pipe joint, then the high pressure fracture liquid converging in high pressure pipe joint is pressed in construction well by entering well lines.Because of the fracturing fluid pressure in high pressure pipe joint definitely large (generally more than 35MPa), the pressure loss in pipeline can be ignored, so without carrying out supercharging again.
Therefore known, the low-pressure manifold of current manifold truck used has just played the transitional function that is connected between fracturing blender truck and fracturing unit truck, if be subject to the restriction of well site landform, large-scale industrialized pressure break, between fracturing unit truck and fracturing blender truck, arrange when distance is larger, the insufficient pressure when fracturing fluid that fracturing blender truck is discharged arrives fracturing unit truck entrance after by low-pressure manifold and line pressure loss (discharge pressure of fracturing blender truck is low, fracturing unit truck suction capacity is very poor), can make fracturing unit truck occur suction phenomenon, not only affect normal pressing crack construction, can make fracturing pump be damaged simultaneously.
