Problems solved by technology

The construction environment of hydraulic fracturing in shale oil and gas formations is even harsher, and the construction time is prolonged. The hydraulic end valve box experiences periodic stress changes, suffers severe wear and fatigue damage during construction, and shortens its service life, seriously threatening normal construction. and construction safety

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the shale oil and gas hydraulic fracturing Y-shaped hydraulic end of the present invention is mainly composed of the following parts: Y-shaped hydraulic end valve box 1, the first centerline 2, the second centerline 4, and the third centerline 3 , discharge valve seat 5, discharge valve 6, discharge spring centralizer 7, discharge plug 8, discharge pressure cap 9, suction valve 10, suction valve seat 11, suction spring centralizer 12, low pressure sand bag 13, Low-pressure liquid inlet 14, high-pressure outlet 15, plunger 16, plunger connection plate 17, discharge valve hole 18, suction valve hole 19, plunger hole 20 are formed.

[0026] Such as figure 2 As shown, the Y-shaped fluid end valve box is formed by a discharge valve hole 18, a suction valve hole 19 and a plunger hole 20 to form a Y-shaped inner cavity.

[0027] Each Y-sh...

Abstract

The invention discloses a shale oil gas hydraulic fracturing Y-shaped fluid end and belongs to the technical field of oil filed hydraulic fracturing equipment. The shale oil gas hydraulic fracturing Y-shaped fluid end comprises a Y-shaped fluid end valve box, a suction mechanism, a discharging mechanism and a plunger mechanism, wherein the suction mechanism, the discharging mechanism and the plunger mechanism are mounted in the fluid end valve box. The center line of the suction mechanism is a first center line. The center line of the discharging mechanism is a second center line. The center line of the plunger mechanism is a third center line. The first center line, the second center line and the third center line are distributed in a Y shape. A discharging valve hole in the discharging mechanism, a suction valve hole in the suction mechanism and a plunger hole form a Y-shaped inner cavity. A fluid end plunger reciprocates in the plunger hole. When the fluid end plunger is far from the intersection of the three center lines, the pressure of the Y-shaped inner cavity is decreased, and fracturing liquid enters the Y-shaped inner cavity from a low-pressure liquid inlet through the suction valve hole; and when the fluid end plunger is close to the intersection of the three center lines, the plunger pressurizes the fracturing liquid in the Y-shaped inner cavity to be discharged through the discharging valve hole.

Description

technical field [0001] The invention belongs to the technical field of oil field hydraulic fracturing equipment. Background technique [0002] Shale oil and gas hydraulic fracturing construction is a systematic production stimulation technology measure. The fracturing hydraulic pressure is injected into the bottom of the well through ground fracturing equipment, and the fractures are opened to form diversion channels between 3000 meters and 4000 meters in the formation, so that no production will be possible. of oil and gas are produced through the wellbore. The fracturing pump truck that provides the main power is the core component of ground fracturing equipment, and the hydraulic end of the fracturing pump truck is the key to whether the construction is normal. The fracturing fluid or sand-carrying fluid (carrying proppant) The fracturing fluid) is sucked through the low-pressure inlet of the hydraulic end, and the reciprocating movement of the plunger pressurizes the fr...
