Abstract
The utility model provides an underground liquid production profile measuring instrument for oil field thermal production, which is used for measuring underground delamination in oil field thermal production. The utility model mainly solves the defect that the products of the same class both at home and abroad can not resist high temperature. The utility model is characterized in that a liquid turbine flow instrument is composed of four symmetrical blades, wherein, a permanent magnetic steel is inlaid on one sheet of blade, and the blades have inclined angles when installed; a flow measuring system is composed of a high temperature-resistant dry reed pipe and a power supply; a shutoff and depth measuring system, a high temperature-resistant cable, etc. are also arranged. The utility model has the characteristics of small diameter and high temperature resistance. As the underground liquid production profile measuring instrument for oil field thermal production is put under pumps from the annular space of production pipe columns and sleeve pipes, measurement is carried out without influencing production. The result of the underground measurement can be directly read out on ground.
Description
The utility model provides the lower leaf of a kind of oil-field thick-oil thermal production well measuring " oil thermal recovery liquid generated underground bottom profiler ".
The viscous crude heating exploitation technology of carrying out both at home and abroad at present is to have injected the saturated vapour of HTHP to oil reservoir, after reaching heat balance, oil reservoir carries out heating exploitation, in recovery process, need the profit liquid output of each oil reservoir of down-hole is tested, dynamically reach exploitation effect so that grasp the profit of each oil reservoir, understand the like product of current domestic and international production, aspect heatproof, do not reach requirement from interrelated data, therefore, do not satisfy the needs of each oil reservoir test of viscous crude heating exploitation.
Task of the present utility model is that design is a kind of at viscous crude heating exploitation laminated distributor under well test oil, water, minor diameter, resistant to elevated temperatures layering measuring instrument, and it has overcome the shortcoming of present similar products at home and abroad non-refractory, and effect is fine, be suitable for.
In order to solve the subject matter non-refractory that measuring instrument exists at present.Researchers are through well-designed, repetition test repeatedly, and it is made up of three parts to have studied successfully " oil thermal recovery liquid generated underground bottom profiler " finally: first is a test instrumentation, this off-balancesheet directly is 25mm, long 1.2mm, heatproof reaches 200-260 ℃.This table divides four parts to make: (a), make the liquid turbine flow instrument, external diameter 22mm, blade is made of four symmetries, and wherein a slice studs with permanent magnet steel, and blade tilt is decided according to fluid flow, be generally the 30-45 degree, when liquid flow through turbine, turbine rotated, and spinning roller speed is directly proportional with flow.This instrument measurable flow amount 5-20m
3/ h; (b), test macro: it is by resistant to elevated temperatures tongue tube (external diameter ψ
OutwardBe 2mm) and the power supply composition; (c), closure works system (5): it makes statocyst by silicon rubber, is provided with electric heater in the capsule and is full of silicone oil.By Ground Control capsule internal heater heating silicone oil, its silicone oil is expanded during work, drive current collecting umbrella and finish the purpose that first action reaches zonal testing.When turbine rotates, magnet steel on the turbine, whenever tongue tube of adhesive rotates a circle, the number of turns and the tongue tube adhesive number of times of turbine rotation are synchronous, it is synchronous being created in the voltage at tongue tube two ends and the adhesive number of times of tongue tube like this, and pulse duration frequency signal is carried the frequency of ground input secondary meter record turbine rotation by cable.Reach layering flow measurement purpose; (d), sounding system: it is made up of electromagnetic coil, when when having the oil pipe short circuit of magnetic orientation by the automatic record of secondary meter, the degree of depth of oil pipe short circuit reaches the purpose of well depth under the calibration instrument; Second portion is a test cable: it is made up of six groups of leads, wherein there are two groups to be nickelchromium-nickelsiliconthermocouple, have four groups to be 2000 meters in red copper lead or the cable that needs length, heatproof 200--360 degree, be processed into silicon rubber insulation, the anti-intensity of drawing is 1.5T (ton); Be divided into secondary meter in the 3rd, it is by underground power supply used power supply, and turbine frequency measurement and computing register system are formed.Above-mentioned three parts connection has then been constituted " oil thermal recovery liquid generated underground bottom profiler ".This instrument is put into the production fluid amount of each oil reservoir of measurement under the pump with the annular space of sleeve pipe outside flow string in the manufacturing process of thermal production well, its survey method be with primary instrument during down to the layer that will measure the Ground Control car simultaneously with the secondary meter control well next time the umbrella that dams of instrument open and make liquid flow through (not stopping production during test) from turbine, at this moment turbine produces rotation, its rotary speed is directly proportional with flow, the number of turns of tongue tube record turbine rotation, and record case sent into the ground secondary meter by high-temperature cable, and record, observational study at any time automatically.
The utility model is compared with prior art: it has minor diameter (25mm) high temperature resistant (200-260 ℃) (being provided with resistant to elevated temperatures insulated cable), in thermal process, under the responding curve of well state this instrument is lowered to the production fluid amount of each oil reservoir of test under the pump from the annular space of flow string and sleeve pipe, but and ground direct reading test result.
Accompanying drawing is an oil thermal recovery liquid generated underground bottom profiler structural representation, and 1 is instrument probe among the figure, the 2nd, and liquid flow hole A, the 3rd, turbine, the 4th, test macro, the 5th, closure works system, the 6th, liquid flow hole B, the 7th, sounding system, the 8th, cable connector, the 9th, high-temperature cable.
An embodiment is described in conjunction with the accompanying drawings: at first buy whole material requesteds test instrumentation of processing and fabricating then to market by accompanying drawing and designing requirement, divide four parts to make: (a), make liquid turbine flow instrument external diameter 22mm, blade is by four symmetries, wherein a slice studs with the permanent-magnet steel blade tilt and determines according to fluid flow, is generally 30-45 degree measurable flow amount 5-20m
3/ h; (b), test macro (4) is by resistant to elevated temperatures tongue tube (external diameter ψ
Outward=2mm) and power supply form; (c), closure works system (5) is made statocyst by silicon rubber, is provided with electric heater in the capsule and is full of silicone oil; (d), sounding system (7), it is made up of electromagnetic coil, when when having the oil pipe short circuit of magnetic orientation by the automatic record of secondary meter, the degree of depth of oil pipe short circuit reaches well depth under the prover; Make test cable, it is that the silicon rubber of the red copper lead of 2000 meters (or needing length) and nickelchromium-nickelsiliconthermocouple and heatproof 200-260 ℃ is processed into by six group leaders, and the cable outside is made by double-layer stainless steel silk armouring, and the anti-intensity of drawing is 1.5t (ton); Make secondary meter, it is by underground power supply used power supply, and turbine frequency measurement and computing register system are formed.Above-mentioned three parts connection is then constituted oil thermal recovery liquid generated underground bottom profiler.
