Based on crude oil measurement equipment shown in FIG. 1, crude oil water content meter can be carried out using method and step as shown in Figure 3
Amount, as shown in figure 3, may include:
Step 301: crude oil sample being placed in the crude oil measurement equipment, and obtains the totality of the crude oil sample
Product.
Installation is not vented formula clean cut system sampling craft process at the production wellhead at oilfield exploitation scene, wherein above-mentioned do not put
Two channels of sampling and production can be set inside empty formula clean cut system sampler, avoid the behaviour being vented before sampling
Make, improves sampling efficiency and reduce the pollution to environment, and may be implemented disposably to successfully complete sampling.
When carrying out crude oil sampling, the lid at the top of above-mentioned crude oil measurement equipment is opened, by the upper of crude oil measurement equipment
Opening alignment sample tap, sampling personnel are in the wind at station place, and above-mentioned be not vented in clean cut system sampler of the opening that commutates samples channel
The sample cock at place at this time produces interception partially liq without influencing in sample cock space.Left-handed opening sample cock hand
Wheel flows into the liquid in sampling flowsheet in crude oil measurement equipment, while sampling personnel and needing to pay close attention to crude oil measurement equipment
Middle liquid level rises situation, and when close to estimated sampling volume, sample collector dextrorotation can close valve at leisure, wherein crude oil
The liquid level of measuring equipment Central Plains oil samples must not exceed maximum scale, the horizontal positioned crude oil equipped with crude oil sample after the completion of sampling
Measuring equipment obtains the total volume of crude oil sample.
In view of the metering of how many pairs of moisture content of sampling quality has very big influence, so the quality of sampling is generally abided by
Follow following principle: it is aqueous in 90% or more person, take mixed liquor 1000g or more；It is aqueous in 60.1%-90% person, take mixed liquor
500g-600g；It is aqueous in 20%-60% person, take mixed liquor 300g；The aqueous person below 20% takes mixed liquor 100g.
Step 302: after crude oil sample is stood the predetermined time, obtaining oil emulsion and free water, and obtain crude oil measurement and set
The volume of standby middle free water.
Under the conditions of Oil Field temperature, the crude oil sample in above-mentioned crude oil measurement equipment is horizontally arranged, is stood pre-
After the fixed time, the crude oil sample in crude oil measurement equipment can be separated into oil-water interfaces clearly two layers of liquid, wherein isolating
Two layers of liquid be at the middle and upper levels oil reservoir, lower layer is free water, and above-mentioned oil reservoir is not pure crude oil but the mixing of crude oil and emulsified water
Object, the oil reservoir that this natural separation comes out are properly termed as oil emulsion.Above-mentioned crude oil measurement equipment level is placed, and based on crude
Graduated scale in measuring equipment obtains the volume for the free water separated.
Step 303: opening drainage hole, the free water in crude oil measurement equipment is discharged.
If will affect the metering to emulsified water in oil emulsion in view of retaining the free water in crude oil measurement equipment,
So after having recorded the volume of free water.The drainage hole for opening crude oil measurement equipment sidewall bottom, will be in crude oil measurement equipment
Free water drainage it is complete, the personnel of operation should pay close attention in crude oil measurement equipment the case where liquid level declines, it is ensured that will be upper
The oil emulsion of layer emits.

Centrifugal device when being centrifuged to oil emulsion in crude oil measurement equipment, centrifugation time generally by ride a bicycle from Oil Field to
Office work place one plow back and forth the time required to determine, plowed from oilfield exploitation scene to office work place one distance back and forth to
It is less 1000 meters.
Step 305: the moisture content of crude oil sample, and the crude oil sample moisture content that will be calculated are calculated according to metric results
Data carry out real-time transmission.
The crude oil sample total volume that metering obtains is counted as V1, free water volume is counted as V2, emulsified water volume is counted as V3, can
To be calculated by the following formula preliminary moisture content:
Due in live manual operation there are certain error, and the centrifugal device that is converted by bicycle of scene without
Emulsified water in oil emulsion is kept completely separate out by method, problem above is based on, by preliminary moisture content obtained by the above method
Laboratory check and correction is carried out, discovery error is 6% hereinafter, be 4%-6% according to the available Optimal Parameters of collation.
In actual operation, when being optimized to preliminary moisture content, the Optimal Parameters value 5% that can be compromised plus one,
I.e. moisture content can be calculated by the following formula:
