Abstract
This invention relates to a method for testing laminated input well continuous flow. The invention applies seales section flowmeter to be sent to the place under the object section with wire by a ordinary lift equipment, then to be lifted uniformly in a speed of 5-100m/min to test the flow of each layer and stops lifting till above the last object layer and finishes testing the whole well absolute input flow, avoiding errors resulted in single-layer flor testing to analyse errors on ground watermeters quickly.
Description
Technical field: the detection method that the present invention relates to separated-zone water infection oil field well water injection rate.
Background technology: in the test of water injection well in oil fields, the detection of carrying out the zonal injection amount is an important link, must be used seal section when the various flowmeters that use detect at present is seated in the water injection allocator working barrel, successively detect individual layer flow and full well yield, this detection technique makes the measuring error increase because seal section is sat tight and the loss of damming, and can't the discriminatory analysis wastage, it is low that efficient is joined in inspection, and workload is big.
Summary of the invention: the purpose of this invention is to provide a kind of separate injection well continuous flow detection method, use this method and can avoid the generation of individual layer flow detection error fully, improve measuring accuracy and inspection and join efficient, can analyze the error condition of ground water meter simultaneously by online detection.The present invention is achieved in that and adopts no seal section flowmeter, use common lifting means earlier flowmeter to be shipped to below the objective interval with steel wire, and then carry at the uniform velocity, on the speed carried be 5～100m/min, make progress successively, test out each laminar flow amount, carried on the flowmeter and carrying on stopping behind last zone of interest, at this moment the water injection rate of Ce Lianging is exactly the absolute water injection rate of full well.The objective interval bottom that flowmeter of the present invention is being tested, since on carry and produce a relative injection flow, this flow is that benchmark is looked flow, when flowmeter passes through water injection allocator, the sectional area of water injection allocator working barrel diminishes, liquid flowing speed strengthens, produce an instantaneous delivery increase value, this increase value is the layering sign, if water injection allocator two partial discharge generation significant changes up and down, can occur one and look flow difference between the upper and lower curve of flow increase value, this difference is exactly the water injection rate of the zone of interest that will test.Referring to Fig. 1.Every technical indicator of the present invention is: measurement range 10～500m
3/ d, 1 grade of measuring accuracy, withstand voltage 25MPa, 0～85 ℃ of working temperature, the longest test duration 2h, data capacity 64KB.Adopt 20 mouthfuls of wells of detection method rig-site utilization of the present invention test, full well yield and day water epiphase ratio error are lower than 2%, and the individual layer flow error is less than 5%, flow rate test one-time success rate 100%.The present invention has the error that can avoid the individual layer flow detection to produce fully, and measuring accuracy and detection efficiency height can be analyzed the error of ground water meter, the advantage that data are accurate, workload is few, detection speed is fast by online detection.
Description of drawings: Fig. 1 is the continuous flow curve synoptic diagram that detection method of the present invention produces, and P1, P2 relative discharge are promptly tested the flow of this zone of interest among the figure.
Embodiment: present embodiment is to adopt no seal section flowmeter, use common lifting means earlier flowmeter to be shipped to below the objective interval with steel wire, and then carry at the uniform velocity, on the speed carried be 20m/min, make progress successively, test out each laminar flow amount, carried on the flowmeter and carrying on stopping behind last zone of interest, at this moment the water injection rate of Ce Lianging is exactly the absolute water injection rate of full well.On the speed carried also can be 10m/min, 30m/min, 40m/min, 50m/min, 60m/min, 70m/min, 80m/min, 90m/min.
