The crude oil sedimentation separation jar of hierarchical monitor
Technical field
The utility model relates to crude oil production technique field, and particularly the oil extraction knockout drum that carries out sedimentation separation behind the ground is a kind of crude oil sedimentation separation jar of hierarchical monitor.Also can be used for the monitoring of medium in all kinds of fluid reservoirs.
Background technology
At present, in the crude oil recovery process, crude oil sedimentation separation jar is the important component part in the crude Treatment system.Enter into crude oil sedimentation separation jar from oil well produced oil water mixture through the feed liquor pipeline, at first get into the feed liquor distributing pipe, be evenly distributed in the crude oil sedimentation separation jar through central tube; Because profit density is different, oil and water meeting natural separation under the gravity effect forms oil reservoir and water layer in crude oil sedimentation separation jar in crude oil sedimentation separation jar, and oil is on top, and water is in the bottom, and the middle part forms water to oil area.Top at crude oil sedimentation separation jar is equipped with collection tank, and the crude oil on top flows out crude oil sedimentation separation jar through collection tank and flow line; Water spills into the water outlet pipeline through crude oil sedimentation separation jar bottom collector pipe through balanced reservoir.Can keep stable level in the crude oil sedimentation separation jar.Crude oil sedimentation separation jar has the function of regulating oil-water-layer.
If medicament, temperature, process lot size occur and come the factors vary such as rerum natura of liquid measure, can cause oil water mixture to be not easy to separate, cause the fuel-displaced moisture height of crude oil sedimentation separation jar; Crude Treatment is defective, and the water outlet oil content is big, and the sewage disposal index is difficult to realize; At this moment, crude oil sedimentation separation jar oil-water-layer is disorderly, needs every artificial jar distribution situation of measuring oil-water-layer that goes up of carrying out at a distance from 1-2 hour; Be used for collecting data, instruct and produce, ensure that the crude Treatment system normally moves.Operating personnel frequently go up jar, and labour intensity is big, and there is potential safety hazard in work high above the ground.
The observation window of installing on the blowdown pipeline of crude oil sedimentation separation jar bottom can only be observed settling tank bottom profit distribution situation, can not monitor important height oil-water-layer in the settling tank.
The utility model content
The purpose of the utility model is: the crude oil sedimentation separation jar that a kind of hierarchical monitor is provided; Change a jar inner structure; Set up a cover differing heights monitoring pipeline, can pass through observation window and sample point, observe settling tank interior oil water layer thickness at any time and change and distribution situation; Reduce the water content in crude oil of separating, guarantee that crude system can normally move.
The technical scheme that the utility model adopts is: the crude oil sedimentation separation jar of hierarchical monitor comprises tank body, collection tank, balanced reservoir, feed liquor distributing pipe, collector pipe, reception standpipe, hierarchical monitor house steward, blowdown pipeline, observation window, sample valve; At the tank body inner top collection tank is arranged, the bottom of collection tank is connected with oil exit pipe, and oil exit pipe is communicated with the flow line of tank wall; Collector pipe is arranged at the bottom at tank body, and collector pipe is communicated with balanced reservoir on the tank wall, and the bottom of balanced reservoir is connected with drainpipe, and drainpipe is communicated with the water outlet pipeline of tank wall; The feed liquor distributing pipe is arranged in tank body, and the feed liquor distributing pipe is communicated with feed tube, and feed tube is communicated with the feed liquor pipeline of tank wall; On the outer wall of the bottom of tank body, blowdown pipeline is arranged, be parallel with the observation pipeline through threeway on the blowdown pipeline, there is valve at the two ends of observing pipeline, on the observation pipeline, are connected with observation window; It is characterized in that: in tank body, be fixed with the reception standpipe of 3~10 differing heights, the lower end that receives standpipe is connected with respectively draws pipeline, draw and be connected with stop valve, ball valve on the pipeline, and 3~10 is drawn pipeline and is connected to a hierarchical monitor house steward; Hierarchical monitor house steward's a end is connected with sample cock, and hierarchical monitor house steward's the other end is connected to be observed on the pipeline, and the hierarchical monitor house steward is connected on the observation pipeline at the observation window upper reaches.
The top of adjacent two reception standpipes and the range difference of tank base are between 1~3m, and the top height of minimum reception standpipe is 3m.
The crude oil sedimentation separation jar operation principle of summary hierarchical monitor.Set up many in a cover and receive the hierarchical monitor device that standpipe is formed; To mirror pipeline is connected to crude oil sedimentation separation jar operation room and links to each other with observation window; At the by-pass valve control of operation room, can realize observing each interval oil-water-layer varied in thickness and distribution situation in the crude oil sedimentation separation jar through the reception standpipe (monitoring pipeline) of switching differing heights.
The beneficial effect of the utility model: the crude oil sedimentation separation jar of the utility model hierarchical monitor can detect differing heights layer position profit distribution situation in the tank body respectively.When the profit disorder appearred in crude oil sedimentation separation jar, operating personnel do not use jar just can observe a jar interior profit layering situation; The operation number of gauging sampling is reduced to 1 people by 2 original people; Be reduced to 2 minute in by 15-30 minute sample time.Monitoring, sampling mode easily in the crude oil sedimentation separation jar operation room have been eliminated the operative employee and have frequently been gone up jar the existing potential safety hazard of measurement, have reduced operative employee's labour intensity.
