Description
Technical Field
The utility model belongs to the technical field of the oil well tolerance measurement and specifically relates to a novel small tolerance of oil well measures device.
Background
The metering room is an important facility in oil field production, and is mainly used for metering the liquid production amount and the gas production amount of an oil well and realizing the fine management of the oil well. With the continuous deepening of later exploitation of oil fields, the stratum capacity is continuously reduced, the gas content of stratum crude oil is very weak, the stratum crude oil is basically not degassed or only can be separated from a small amount of gas after being exploited from the ground, and the requirement of oil pressing during normal metering cannot be met.
The existing oil pressing modes of the low-air-quantity metering room are mainly three, namely single-well oil pressing, balance tank oil mounting and oil discharging pump oil mounting, but the three oil pressing modes have the defects of different degrees and greatly affect the safety, efficiency and accuracy of metering.
(2) Single well oil press
The single well oil pressing is the same as the oil pressing in normal oil measuring and gas measuring, the oil pressing is carried out by reversing one well after the measurement is finished, only one well with large gas quantity is found for oil pressing in normal measurement, and the single well oil pressing is carried out by finding one well with the maximum relative gas quantity from the oil wells governed by the low gas quantity measuring room. It should be noted here that the gas is not produced at all during the low gas flow metering, a certain amount of gas can be produced in each well, the separator can discharge the liquid as long as the gas is available, and only the liquid discharge time is different, the liquid discharge time is shorter when the gas flow of a single well is larger, and the liquid discharge time is longer when the gas flow of the single well is smaller. The oil pressing method of the single well oil pressing in the low-air-volume metering room basically needs 6 to 8 hours for one time, and even more, the oil discharging needs more than 20 hours for one time, so that the metering efficiency is seriously influenced, and especially for the metering rooms with more oil wells in jurisdiction, the normal metering task can not be completed completely, so the single well oil pressing problem is long time and low efficiency.
(2) Balance tank oil press
The balance tank is installed under the separator, the balance tank is connected with the gathering flow to realize closed gathering, so that gas released in normal production can form a gas cap at the upper end of the balance tank, the gas cap is connected with the upper gas space of the metering separator, when the gas cap of the balance tank and the upper gas space of the metering separator are conducted, the gas cap and the upper gas space of the metering separator are in the same pressure system, and liquid in the separator flows into the balance tank under the action of dead weight to realize oil pressing due to the higher position of the separator. The method has the advantages that the gas cap is formed in the balancing tank when produced liquid can be separated to give out gas, the larger the gas amount which can be separated from the produced liquid is, the larger the formed gas cap is, but the gas which can be separated from the produced liquid in a low-gas-amount metering room is limited, the gas cap can not be formed above the balancing tank, the prerequisite that the gas cap is connected with the gas space on the upper part of the separator can not be achieved, and the oil pressing can not be achieved. Meanwhile, the investment for installing a balance tank needs at least 20 ten thousand, the balance tank is generally buried underground, the normal detection of the equipment flow is very difficult, and even more, due to the topography problem, the balance tank is in water-logging corrosion for a long time, and the potential safety hazard generated by the balance tank cannot be ignored. From the above analysis, it can be seen that oil can be pressed from a single well when the gas amount is large, and the balancing tank has no meaning when the gas amount is low, but one extra device has one more risk in terms of the safety of the system. Therefore, the balance tank oil is not used much and has little risk.
(3) Oil-pressing oil of oil-discharging pump
The oil-discharging pump presses oil, namely a gear pump is directly arranged at an outlet of a metering separator, and liquid in the separator is directly pumped into a gathering and conveying system. Because the metering separator is a closed space, the pressure in the separator can be reduced inevitably after the liquid in the metering separator is pumped away by the oil discharge pump, once the single-well metering gate is opened next time, because the back pressure of the single well is higher than the pressure of the current separator, a large amount of liquid in the single well and the pipeline can flow into the separator in a short time, and the metering accuracy is seriously influenced. Therefore, the problem of oil pressurized by the oil discharge pump is mainly that the oil is not accurately metered.
At present, the conventional vertical separator is still used as a main means for metering the gas flow of the single well of the oil field. The vertical separator calculates the gas production rate of an oil well through the time of the gas liquid level in the device and the production pressure, but for an intermittent oil well, an oil well with small gas quantity and micro gas quantity has long gas production time, and even does not produce energy gas when the metering condition cannot be met. The gas production of the oil well is taken as basic data, and is not allowed to be lost in terms of production requirements.
Application No.: 201020597246.9 discloses a gas sampler for oil and gas well head, which is used for sampling gas from oil well head. A top pipe is fixed at the top of the separator tank body; the top pipe is connected with a liquid outlet pipe and a gas sampling pipe; a tank middle pipe is fixed in the middle of the separator tank body, one end of the tank middle pipe is arranged in the separator tank body, the outer end of the tank middle pipe is connected with a tee joint, one interface of the tee joint is connected with a pipeline, and a quick joint is fixed at the end part of the pipeline; the other connector of the tee joint is connected with a liquid inlet pipe; a tank bottom pipe is fixed at the bottom of the separator, the tank bottom pipe is connected with a liquid inlet pipe, a quick joint is fixed at the end part of the liquid inlet pipe, and a valve is fixed on a pipeline between the end part of the liquid inlet pipe and a tee joint connected with the tank bottom pipe; a pipeline is connected between a tee joint connected with a tank bottom pipe and a tee joint connected with a tank middle pipe, and a valve is fixed on the pipeline. The method has the advantages that a high-purity gas sample can be taken from the wellhead of the oil production well, and a liquid sample can be taken at the same time, so that a basis is provided for providing safe air using amount for adjusting a scheme.
