Description
Technical field
The utility model relates to technical field of petroleum extraction, specifically, is a kind of portable individual well metering device with secondary oil drum.
Background technology
China's single well metering device is in a primary research stage at present, be on product structure, product quantity, automation control, data remote technology, intelligent degree, the security performance all and in the world the single well metering device technical level there is a big difference, on the oilwell produced fluid amount measurement technology, there are a lot of difficulties, become a big technical barrier of each petroleum metering work.
The individual well liquid producing amount measure of oil well is to provide foundation in order to carry out WPA, science formulation production measure and technical scheme, also is one of important means that reduces measurement shoutage, raising oil well management level.China enters secondary, tertiary oil recovery period, and it is particularly important that the accuracy of individual well liquid producing amount measure more seems, liquid producing amount measure can improve the degree of reliability of oil pool analysis, reservoir description accurately.At present when design and manufacturing single well metering device, its key issue is the oil pressure problem that producing well brings, after single well pipeline crude oil feed liquor piece-rate system is separated, crude oil liquid enters the metering device weighing, its immense pressure is directly impacted electronic scale by batch box, the weight of impact of instantaneous generation can exceed the weighing scope of electronic scale, causes the damage of electronic scale.Therefore a lot of single well metering device practicality are not strong, and the popularity of its application also is restricted.
Summary of the invention
The utility model improves the liquid producing amount measure precision in order to improve existing individual well liquid producing amount measure method, reduces labour intensity, releases the instantaneous pressure that causes when gathering sample, and a kind of portable individual well metering device with secondary oil drum is provided, and can address the above problem.
The utility model is to adopt that sample weighing method solves the weighing problem more than 500 kilograms, and its technical scheme is: have a secondary oil drum in device.
The portable individual well metering device of the secondary oil drum of this band, comprise the skid support, batch box, electronic scale, secondary oil drum, screw pump, generator, storage battery, electric control box, electrical ball valve, safety valve, flap valve, connecting line etc., be divided into six big systems: the device support system, the weight metering system, the PLC program control system, the sample input-output system, power supply system, the signal data transmission system, be connected in sequence, it is characterized in that: have the secondary oil drum that a volume reaches 1 cubic metre in the gravimetric system, be installed on the support in the device support system, secondary oil drum inlet is connected with feed tube, and liquid outlet is connected with batch box.
The function implementation
The utility model utilizes gravity weighing method principle, researches and develops in conjunction with the working method of secondary oil drum to form, and has the function of oilwell produced fluid amount being carried out sample weight metering more than 500 kilograms.When portable individual well metering device is started working, snap joint on the equipment is connected with the outlet of pumping unit of well production fluid, after single well pipeline crude oil feed liquor piece-rate system is separated, crude oil liquid enters secondary oil drum and carries out pressure buffer, the batch box of crude oil liquid after buffering below entering after the metering by electronic scale, returns the crude oil export pipeline by the crude oil of screw pump after with weighing again, whole operation process and transfer of data, and output calculating is finished by the PLC program control system fully.
The beneficial effects of the utility model are: have secondary oil drum in the metering device, can form buffering, the pressure that produces when releasing sampling can directly carry out weighing to sample after the pressure release, directly shows weight, has improved the functional performance of equipment.
