Description
Technical field
The utility model belongs to crude oil oily water separation technique field, specifically is the storage tank water-oil interface determinator that the oil recovery accumulating of a kind of suitable oil field is used.
Background technology
In Petroleum Production, crude oil extraction must pass through multi-purpose station and handle, and makes crude oil water containing≤1.5% ability
Up to standard defeated outward as separator oil.The common disposal route of multi-purpose station is earlier after separation vessel is handled, to make it moisturely reach 5% crude oil, then in storage tank further sedimentation separation to fail requirement reaching outside.The method of sedimentation separation is, after the wet oil standing sedimentation a period of time in the input storage tank, and the profit natural separation, the water that then will be deposited in the bottom is emitted, and that top reaches the outer defeated crude oil of standard that requires is defeated outside petroleum pipeline.In order accurately to control the water discharge in the storage tank, in order to avoid qualified crude oil is discharged with water, cause the waste loss, then need often carry out the mensuration of water-oil interface to the crude oil in the storage tank.The mode that present oil-water contact is measured is: use three grades of STs to take a sample, need two people to cooperate simultaneously, after the staff climbs up storage tank; The opening oilhole; Will be earlier approximate location through range estimation estimation water-oil interface, then sampling jar is sunk in the storage tank, begin sampling from water-oil interface about with next rice; Per ten centimeters samplings once; The accumulative total needs just can be got for about ten times and meet the oil sample that chemical examination requires, and take back the laboratory and carry out assay by the laboratory personnel again, and calculate the position of water-oil interface through computing formula according to the result who draws.The defective that this sampling mode exists is: 1) because the position of the interior water-oil interface of storage tank is difficult to accurate estimation; Sampling jar sinks to the degree of depth and is difficult for holding; Therefore each sampling all needs to operate up and down repeatedly more than ten time, just can collect the oil sample at actual water-oil interface place, complicated operation; Waste time and energy, labour intensity is big; 2) oil sample of gathering must just can calculate the position of crude production rate and water-oil interface through assay, and chemical examination metering, measuring and calculating need then to want half an hour to accomplish, and add sampling operation repeatedly, and work efficiency is very low; 3) sampling, chemical examination continuous data accurate reliability are poor, the accuracy that the water-oil interface position is defined in the influence jar, and directly have influence on the accurate control of waterdrainage amount in the jar thus, be difficult to guarantee the quality and the output of accumulating output crude oil; 4) in sampling process, the switch of sample valve is to hang over the backguy on the valve rod through handling, realizes the keying of sample valve; Because backguy reaches tens of rice, and stack at randomly, bring great inconvenience to operation thus; And need two people to cooperate and to accomplish sampling operation; Cause troublesome poeration, labour intensity is big, and the sampling operating efficiency is low.
The utility model content
The purpose of the utility model provides a kind of easy for operation, can guarantee that the water-oil interface ratio in the storage tank defines storage tank water-oil interface determinator accurately.
The technical scheme that the purpose of realization the utility model is taked is: this device comprises sampling jar and faking device, and wherein, sampling jar has a cylindrical shell; End cover is equipped with at the two ends up and down of this cylindrical shell, and the lower seal end cap is provided with valve opening and the valve body that is used to constitute sample valve, is connected with valve rod on the valve body; Valve rod is provided with compression spring; Valve rod stretches out outside the end cover, and its external part is equipped with carries wire loop, on last end cover, is provided with the transparent hose that the gauging tape articulates ring and is communicated with sampling jar; Faking device has the support body of a band handgrip, through spool gauging tape that is coiled on the spool and the cable quadrant rope sheave that is wound with backguy is housed on the support body.
Be respectively equipped with the gauging tape on said gauging tape and the backguy wire reels and change thorny handle and backguy winding handle.
The storage tank water-oil interface determinator of processing according to such scheme; Can realize the single job sampling, and only need one man operation, can directly obtain the depth location of water-oil interface in the storage tank and the accurate discharge capacity of sedimentation water at the scene; Realize the accurate control of waterdrainage amount, need not chemically examine.Thus, guarantee the quality and the output of storage tank accumulating output, also improved the operating efficiency that water-oil interface are measured simultaneously greatly.Compared with prior art, this device has reasonable in design, and is easy for operation, labour intensity is low, advantages such as reliable operation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1, the storage tank water-oil interface determinator of the utility model comprises sampling jar and faking device; Wherein, sampling jar has a cylindrical shell 5, and end cover 6,1 is equipped with at the two ends up and down of this cylindrical shell 5; Lower seal end cap 1 is provided with valve opening 1-1 and the valve body 2 that is used to constitute sample valve, is connected with valve rod 4 on the valve body 2, and this valve rod 4 is provided with compression spring 3; Valve rod 4 stretches out outside the end cover 6; Its external part is equipped with carries wire loop 7, and last end cover 6 is provided with the transparent hose 17 that the gauging tape articulates ring 8 and is communicated with sampling jar, and transparent hose 17 is communicated with sampling jar through a metal tube 18.Faking device has the support body 11 of a band handgrip 12; Through spool 15 gauging tape 9 that is coiled on the spool 15 and the cable quadrant rope sheave 13 that is wound with backguy 16 are housed on the support body 11, being respectively equipped with the gauging tape on gauging tape 9 and the cable quadrant rope sheave 13 changes thorny handle 10 and backguy winding handle 14.
Principle of work: the storage tank water-oil interface determinator of the utility model in use, the sampling operation person climbs up the oil storage tank deck, the opening oilhole; The free end of gauging tape 9 and backguy 16 is articulated ring 8 and carries wire loop 7 and be connected with said gauging tape respectively; According to the water-oil interface estimation degree of depth sampling jar is sunk in the storage tank together with gauging tape 9, backguy 16 and transparent hose 17, and sampling jar is sink to below the water-oil interface, then; Through on lift line 16; Open sample valve because transparent hose 17 and atmosphere, the sedimentation water of storage tank bottom under the pressure of top crude oil and water with getting into naturally in sampling jar and the transparent hose 17.At this moment; Loosen backguy 16, close sample valve, the record sampling jar sinks to the degree of depth; Operate faking device again and propose sampling jar; Measure and write down the distance of liquid level to the sampling jar inlet in the transparent hose 17, the difference pressure principle of based on crude and water can calculate the depth location of water-oil interface in the storage tank and the accurate discharge capacity of sedimentation water at the scene.
