The utility model is to be achieved through the following technical solutions above-mentioned purpose.
Multi-functional II type low-pressure manifold device comprises: transverse tube, straight tube, it is characterized in that: the two ends of a pair of horizontal transverse-pipe are connected to form II type symmetrical structure by bend pipe, the inclined tube straight tube parallel with two, with the perpendicular low-pressure manifold intake that is provided with at least one union joint, butterfly valve and short flange spool formation of straight tube, be connected with the outlet opening of fracturing blender truck; Outlet opening with the perpendicular low-pressure manifold that at least one union joint, butterfly valve and long flange spool formation are housed of transverse tube, is connected with the intake of fracturing unit truck; Described straight tube is provided with 1-12 intake, and transverse tube is provided with 1-16 outlet opening; Sampling manifold is installed on transverse tube; In the middle of described straight tube, 1/2 position is provided with butterfly valve, by controlling its switch, both can realize small displacement, operation on a small scale, also can realize two cover Frac units and carry different of the fracturing fluid fracturing work process requirements.For ultra-large fracturing work, also can connect with two covers or more low-pressure manifolds respectively to connect by low-pressure hose uses.
The beneficial effects of the utility model are:
1. multi-functional II type low-pressure manifold device forms low-pressure manifold by a pair of transverse tube and a pair of straight tube, and the quantity of the connecting interface that has been multiplied, can mate more fracturing blender truck and fracturing unit truck, has met the demand of massive hydraulic fracturing operation.
2. due to multi-functional II type low-pressure manifold device overall structure symmetry, be convenient to putting, constructing of other unit equipments of well site, overcome the difficult problem that well site is little, working vehicle is many, difficulty is put; Weaken liquid flow impact simultaneously, reduced the energy loss of fluid, feed flow is steady, can improve pressing crack construction quality.
3. on transverse tube, be provided with sampling manifold, after can mixing fracturing blender truck, fracturing fluid is taken a sample to check, and is convenient to the of the fracturing fluid fluid property of analyzing and testing and whether reaches requirement.
4. by controlling butterfly valve on straight tube, both can realize on a small scale, small displacement operation, also can realize two cover Frac units and carry different fracturing fluids simultaneously, meets special fracturing work technological requirement.
