Abstract
The utility model relates to a reversed flow type on-site pressure-measuring apparatus for high-pressure construction, comprising a fracturing pump. The outlet of the fracturing pump is communicated with a well mouth by a pipeline and a valve, and is provided with an atmospheric valve. The reversed flow type on-site pressure-measuring apparatus for high-pressure construction is characterized in that one pipeline is communicated with the inlet and the outlet pipelines of the fracturing pump; a stop valve and a high-pressure needle valve are arranged on the pipeline; meanwhile, the inlet of the fracturing pump is respectively communicated with the exhausting branch pipe and the agitator tank of a truck-mounted blender by the pipeline, and stop valves are respectively arranged. The high-pressure needle valve is used for regulating pressure, which enables the pressure to stabilize. The utility model not only is convenient to operate, but also the workload of construction preparation is less, and the reversed flow type on-site pressure-measuring apparatus for high-pressure construction has no environmental pollution, and staffs' personal safety can be ensured.
Description
The utility model is high pressure working-yard pressure testing devices such as a kind of pressure break, acidifying, well cementation of reverse-flow type on-site voltage-measuring apparatus, particularly a kind of oil field.
In the high pressure work progress,, on-site voltage-measuring must formally carried out midway before the infusion in well for the unlikely generation high-pressure pipe member that guarantees to construct leaks and normally carrying out and assurance equipment and personal safety of influence construction.At present both at home and abroad the mode of pressing crack construction on-site voltage-measuring is nothing more than being fracturing truck pressure testing and with test pump pressure testing dual mode.Use the fracturing truck pressure testing, if close atmospheric valve, then pressure rises rapidly, and is uncontrollable, and it is constant to keep a certain pressure test pressure for a long time.If the unlatching atmospheric valve, then fluid loss causes waste and environmental pollution.Use the test pump pressure testing, the one, increased the investment and the place area occupied of equipment, need connecting line simultaneously, make preparation of construction working time lengthening.
The purpose of this utility model provides a kind of novel pressure testing device, it can overcome existing shortcoming in the prior art, rising pressure that can be stable, and it is constant to keep certain pressure for a long time, the work of preparation of construction simultaneously is easy, can not cause the pollution of any liquid waste and environment.
The purpose of this utility model is achieved in that it comprises fracturing pump, the fracturing pump outlet communicates with well head by pipeline and valve, and atmospheric valve is housed, the entrance and exit pipeline that it is characterized in that a pipeline UNICOM fracturing pump, stop valve and high pressure needle valve are housed on this pipeline, communicate with discharge manifold, the stirred pot of truck-mounted blender respectively by pipeline in the porch of fracturing pump simultaneously, and respectively stop valve is housed.
The utility model has the advantages that:, can make pressure stability by the high pressure needle pressure regulating valve.During construction other pipeline needn't be installed, only need to close the conversion of opening operations such as several valves can be realized circulating, pressure testing, formal infusion, not only easy to operate, and the preparation of construction workload is little, saves time, and reduces floor area, not to the pollution of environment.High pressure needle valve is protected staff's personal safety in the operation of measuring truck medium and long distance in addition, also convenient simultaneously observation.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is the structural representation of available technology adopting fracturing truck pressure testing.
Fig. 2 is a structural representation of the present utility model.
5 is fracturing pumps among Fig. 1, general every group of fracturing truck is the 3-5 platform, its inlet communicates with the discharge manifold 3 of truck-mounted blender by last water tube hose 4, outlet communicates with high pressure pipe joint 7 by fracturing truck vent line 6, high pressure pipe joint communicates with well head 10 by head valve 9, an atmospheric valve 8 is housed simultaneously, and truck-mounted blender is discharged manifold 3 and is communicated with truck-mounted blender stirred pot 1 by sand pump 2.During pressure testing, close head valve, if simultaneously atmospheric valve cuts out, pipeline inner pressure rises swift and violent, and is wayward.If open atmospheric valve, then fluid loss causes waste and to the pollution of environment.
The utility model is reequiped in every group of fracturing truck one or more, as shown in Figure 2, on the water tube hose 4 threeway 11 and 17 are being installed respectively on the fracturing truck vent line 6 and on the fracturing truck, and with low pressure recirculatory pipe 18 with their UNICOMs, stopcock 12 and high pressure needle valve 13 are housed on the low pressure recirculatory pipe, the other end at the fracturing truck upper hose is discharged manifold 3 and truck-mounted blender stirred pot 1 by threeway 16 difference UNICOM truck-mounted blenders, and stop valve 14 and 15 are housed respectively.The utility model is closed head valve 9, stop valve 15, stopcock 12 at circulation time, opens atmospheric valve 8, stop valve 14.The truck-mounted blender feed flow, make the liquid of discharging in the manifold have certain pressure, start fracturing pump, liquid is discharged manifold through truck-mounted blender and is discharged in the waste liquid pool through stop valve 14, fracturing pump, high pressure pipe joint and atmospheric valve, and other not have the loop program of fracturing pump of change same as the prior art.During on-site voltage-measuring, close head valve 9, atmospheric valve 8, stop valve 14, open stop valve 15, stopcock 12, suitably open high pressure needle valve 13, the truck-mounted blender feed flow, start arbitrary fracturing pump that does not have change among Fig. 2, the flow direction of liquid is such: truck-mounted blender is discharged last water tube hose-stop valve 15-truck-mounted blender stirred pot-sand pump-truck-mounted blender of the fracturing pump after the fracturing pump vent line-stopcock-senior middle school's needle-valve-low pressure recirculatory pipe-change after water tube hose-fracturing pump-fracturing pump vent line-high pressure pipe joint-change on manifold-fracturing pump and is discharged manifold.Liquid becomes high pressure by low pressure by fracturing pump the time, by high pressure needle valve the time, become low pressure by high pressure again.Adjust high pressure needle valve, can make the pressure in the pipeline keep certain hour, up to finishing the pressure testing program in arbitrary value, stop fracturing pump, make tensimeter be shown as 0, close atmospheric valve, stopcock, stop valve, open head valve, just can be formally in well infusion.
