Description
Technical field
The utility model relates to technical field of petroleum extraction, particularly a kind ofly connects the pressure meter thread conversioning joint that pressure meter is used to gather the oil well pressure data, is the antifreeze joint of a kind of pumpingh well well head pressure table specifically.
Background technology
The pressure meter meter connector is widely used in the production of oil well in the Petroleum Production as a kind of screw thread conversion linkage of oil well pressure table.The pressure tapping of using on the oil field at present has simple and easy meter connector and special-shaped meter connector.Special-shaped meter connector is compared with former old-fashioned pressure tapping has tangible advantage, and it has and connects reliable, calibration and replacing need not to be equipped with the emptying flow process, and end face seal need not characteristics such as rubber cushion, compact conformation.But special-shaped meter connector in use exists following problem and limitation:
1, joint only plays the effect of screw thread conversion connection pressure meter, since oil pressure gauge (back pressure table), special-shaped meter connector be connected with the well head threeway 1/2 " pipeline, valve member are connected; and pressure meter is the end of pilot flow process; well liquid pilot and not flowing in the pilot flow process; well liquid forms viscous flow in the joint; easily freeze winter, cause the pressure meter bursting by freezing, can't normally gather force value.
Though 2, the pressure meter of this joint connection is placed in the well head incubator, but the preventing freeze in winter problem relies on the electric heater in the incubator always, though adopt the electric heater insulation to reach to manometric insulation requirement, but consumed power, with an anti-riot electric heater of DNB-1.5 is example, day power consumption 3.6KWh, whole soak (1-March 1 December or-15 ℃ begin the energising insulation) needs consumed power 324KWh, and has the electric leakage potential safety hazard.
The utility model content
The purpose of this utility model is: provide a kind of pumpingh well well head pressure table antifreeze joint, guaranteeing that pressure meter normally connects on the basis of value, the temperature of utilizing well liquid fluid to carry is conducted heat to pressure meter by heat pipe, realize winter in the well head incubator under the no heating environment to manometric anti-freezing and heat-insulating, simultaneously, solve the deficiency that former special-shaped meter connector exists, satisfy the production requirement of oilfield.
The technical solution adopted in the utility model is: the antifreeze joint of pumpingh well well head pressure table mainly is made up of adapter body, heat pipe, inlet union and outlet connection, it is characterized in that: the threaded one end of adapter body is connected with inlet union, the other end of the adapter body heat pipe that has been threaded, heat pipe inserts in the adapter body.Between adapter body and heat pipe, form annular liquid storage cylinder.Heat pipe is that cylindric center is porose, and there is the pressure meter connecting thread outer end of heat pipe.On the outer wall of adapter body, be fixed with outlet connection.Inlet union is connected on the pressure measurement pipeline, and outlet connection is connected on the liquid output pipe line, and the well head high-temp liquid enters in the antifreeze joint from inlet union, and the liquid storage cylinder of flowing through passes to heat pipe with temperature.The pressure meter that connects on the heat pipe pressure against the ends table connecting thread can receive the heat of heat pipe, and is not frozen.
Inlet union and outlet connection adopt general screw thread, can be connected with the pressure guiding pipeline link, and the pressure meter connecting thread of heat pipe outer end adopts pressure meter carefully to detain screw thread, can be connected with pressure meter.Even also can guarantee manometric normal pressure value of adopting so in the winter time under the extremely low temperature ambient conditions, reach requirement to oil well pressure monitoring.The antifreeze joint overall structure of pumpingh well well head pressure table is simple, compact and reasonable, handling ease, easy for installation, dependable performance.
The beneficial effects of the utility model: the antifreeze joint of the utility model pumpingh well well head pressure table has been realized the flowing of fluid in the oil pressure pilot flow process, avoided fluid in pipeline and joint, to remain in a standstill, make fluid be in flow regime in joint, it is frozen because of viscous flow at low temperatures to have eliminated fluid.Substituted present meter connector in the pumpingh well production, can be implemented in condition downforce table antifreeze of no electric heater heat tracing in the winter extremely low temperature well head incubator, satisfied pumpingh well manometric production requirement.The antifreeze joint fitting operation of pumpingh well well head pressure table is operated identical with former simple and easy meter connector, special-shaped meter connector, cost of production and management cost have been reduced, soak of a bite pumpingh well is power consumption 324KWh only on average, and eliminated the electricity consumption insulation and produced the hidden danger of electric leakage, improve the safety factor of equipment, facility, reduced personnel labor to a certain extent.
