Description
Technical field
The utility model relates to oilfield water-doped viscosity reduction water meter on-line cleaning and demarcates technology, specifically a kind of oil well watering viscosity reduction water meter on-line cleaning and caliberating device.
Background technology
Viscous crude field exploitation is an important component part of crude oil in China output.Viscous crude has that denseness is large, the feature of poor fluidity, and exploitation difficulty is larger, at present the main thickened oil watering technique that adopts.Because water mixing water is the common sewage of field joint stations or block station sedimentation, salinity is high, impurity content is high, fouling is serious, often burn into stops up water meter between water mixing, causes to measure or to measure inaccurate, causes crude production rate metering inaccurate, cannot formulate in time and optimize or upper product measure, give on daily management and crude oil and produce and bring very big inconvenience.Traditional method is manually by water meter disassembly, cleaning, according to water meter management regulation, after water meter calibration coefficient before the deadline, then uses, and the water meter feed technique supervisory station that approaches the term of validity re-uses after demarcating.Mainly there is following problem.
First, water mixing metering is inaccurate, and the one, after water meter cleaning before the deadline, general employing does not stop well demarcates, and measures oil well mixing production fluid under different watering quantities with separation vessel that is:, by difference, calculates water meter coefficient.Because oil well is not that continuous uniform is produced, in separation vessel metering process, water mixing system is also in the medium reason of dynamic change, the water meter system error calibrating is larger, especially production fluid is less than to the oil well error of 10.0 tons larger, and it is the situation of negative that some oil wells there will be production fluid amount.Even if adopt and to stop well and demarcate, condition is different when with oil well production, and error is still larger.The 2nd, for the calibrated water meter of feed technique supervisory station, because of used medium in water meter calibration process also not exclusively identical with on-the-spot water mixing system with on-the-spot different, pressure and other parameters, so calibrated water meter error is also larger.In addition, because calibrated water meter is not generally used on the oil well before demarcation, on different oil wells, use and also can cause certain error.
Secondly, water meter scrappage is high, and repeatedly the water meter of dismounting is sent to after demarcation, and scrappage is high to be approached more than 40%, causes cost for oil production to increase.
The 3rd, according to water mixing table administrative provisions, monthly water mixing table at least cleans once, and post labor strength is large, wastes time and energy.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of oil well watering viscosity reduction water meter on-line cleaning and caliberating device are provided.
The technical solution of the utility model comprises: clean and demarcate two parts; Cleaning part is comprised of sewage draining valve, dosing funnel; Demarcate part by demarcate flow process, by-pass valve control, table early gate, non-with table, show late gate, non-ly with table bypath valve, forming.
The sewage draining valve of the cleaning part in above-mentioned oil well watering viscosity reduction water meter on-line cleaning and caliberating device is arranged on control valve and between with table, and dosing funnel is arranged on showing and coming between penstock.
The demarcation flow process of the demarcation part in above-mentioned oil well watering viscosity reduction water meter on-line cleaning and caliberating device is arranged on control valve and is using between table, demarcate that by-pass valve control, table early gate are housed in flow process is successively non-with table, table late gate, in parallel non-with table bypath valve above and after table late gate at table early gate.
The beneficial effects of the utility model are: be applicable to on-line cleaning, demarcate water meter, reduced water meter scrappage, crude oil measurement error was reduced in current ± 5% by-17%～+ 30% of the past, reached the stoichiometric level of non-heavy crude well, for oil well crude oil production daily management and metering and measure, formulate reliable technical information is provided, time saving and energy saving, alleviated post workman's labour intensity, the problem that has simultaneously solved water source when separation vessel cleans, can facilitate cleaning separator timely.

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described:
Oil well watering viscosity reduction water meter on-line cleaning and a caliberating device, comprising: clean and demarcate two parts; Cleaning part is comprised of sewage draining valve 101, dosing funnel 102; Demarcate part by demarcate flow process 201, by-pass valve control 202, table early gate 203, non-with table 204, table late gate 205, non-ly with showing bypath valve 206, forming.The sewage draining valve 101 of cleaning part is arranged on control valve 302 and is using between table 304, dosing funnel 102 is arranged on table 304 and coming between penstock 305, at dosing funnel 102, add clean-out system, react after 1 hour with incrustation scale, the incrustation scale that makes to be attached in tube wall internal diameter and water meter departs from, and with the rolling action of current, its sewage draining valve 101 is discharged to the object that reaches On Line Foul Removing Technology.The demarcation flow process 201 of demarcating part is arranged on control valve 302 and is using between table 304, demarcate by-pass valve control 202, table early gate 203, non-with table 204, table late gate 205 be housed in flow process 201 successively, table early gate 203 above and table late gate 205 in parallel non-with table bypath valve 206 below.
Operation steps:
First, be recorded in table 304 water mixing pressure and watering quantity reading.
Secondly, open at the bypath valve 303 with table 304, close control valve 302, open by-pass valve control 202, the same before regulating water mixing pressure, watering quantity etc. and demarcating, guarantee that calibration process is consistent with the normal manufacturing parameter of oil well.
The 3rd, a section interior record separator measures the time and with table 304 reading, calculates separation vessel metering water quantity and using table 304 water mixing coefficient at one time.
The 4th, if water mixing coefficient within 0.8～1.2, the coefficient that is oil well watering metering with the new coefficient of demarcating, if not in normal range, demarcates after cleaning again or changes with table 304, non-ly with table 204, can demarcate in advance coefficient.
Water meter calibration coefficient=separation vessel metering water quantity/water meter measurement water yield
Actual watering quantity=water meter measurement the water yield * water meter calibration coefficient
The 5th, in calibration process, can adopt different watering quantities repeatedly to demarcate, guarantee water mixing coefficient accurately and reliably.
