Problems solved by technology

[0005] Second, the incoming liquid is generally at room temperature. After entering the open metering tank, the dirty oil solidifies quickly and is difficult to pump. The site needs to be purged with steam before it can be pulled away by a tanker;
[0006] Thirdly, the current measuring tank is open to operate, which pollutes the environment and has poor working conditions on site;

Embodiment

[0041] like Figure 1 to Figure 3 As shown, this embodiment provides an intelligent integrated metering device. It should be noted that the multiphase flowmeter, instrument control cabinet and electrical control cabinet in this embodiment are purchased, and their control software and connections are in the prior art. , will not be repeated here.

[0042] In this embodiment, the intelligent integrated metering device mainly includes a skid-mounted box with a rectangular parallelepiped structure, and is arranged in the skid-mounted box and is used to collect the waste liquid buffer tank 1 for the wellhead test production liquid. The sewage lift pump 2, which is connected to the waste liquid buffer tank 1 by pipeline and used to pressurize the wellhead test liquid buffered by the waste liquid buffer tank 1, is arranged in the skid box and is connected to the sewage lift pump 2 by pipeline 2. The cyclone desander 3 used to separate the sand body in the test production fluid at th...

Abstract

The invention discloses an intelligent integrated metering device. The intelligent integrated metering device comprises a skid-mounted box, and further comprises a waste liquid buffer tank, a sewage lifting pump, a cyclone desander, a vacuum suction pump, a cooling water tank, a multiphase flowmeter, a calibration tank, a sewage / sump oil buffer tank, a sewage / sump oil truck loading pump, boiler equipment, an instrument control cabinet and an electrical control cabinet which are laid in the skid-mounted box. The invention further provides a metering method of the intelligent integrated meteringdevice. Through the scheme, the intelligent integrated metering device and the metering method have the advantages of simple structure, reliable operation accurate metering and the like, and have quite high practical and promotional value in the technical fields of wellhead waste liquid treatment and metering.

Description

technical field [0001] The invention relates to the technical field of wellhead test production liquid processing and metering, in particular to an intelligent integrated metering device. Background technique [0002] At present, the development of the wellhead oil and water test production residual liquid treatment process in the prior art is relatively lagging behind. Among them, the main source: the oil test operation of each well is generally 7-10 days, and the waste liquid generated during the oil test process mainly includes 4 types (ejected liquid after fracturing, pumped oil and water test liquid, and residual liquid in the metering tank) and operating table residual liquid), in which the suction oil and water waste liquid is the main one. In the prior art, the main treatment method of wellhead residual liquid: two 10m 3 The (5*2*1m) open measuring tank receives the wellhead test liquid (there is also a small measuring tank above, and the residual liquid is used fo...
