Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas well logging, in particular to a soluble tracer placement short circuit. Background Art

[0002] An oil field is the sum of oil and gas reservoirs within the same oil and gas producing area under the control of a single geological structure (or formation). Tracers are used in the logging process of oil fields. Tracers are markers added to observe, study and measure the behavior or properties of a substance in a specified process.

[0003] A short-circuit connector is used in the tracer delivery process. The short-circuit connector and the oil pipe are extended into the oil field, and the tracer is dropped into the oil field for marking through the short-circuit connector. After the current short-circuit connector discharges the tracer for a period of time, when the tracer reacts, it will be extracted and its trace elements will be tested. Because the short-circuit connector can only discharge the tracer, it makes it difficult to balance the amount and frequency of tracer discharge, resulting in uneven distribution of tracers in a single well, which in turn affects the accuracy of logging data.

[0007] Preferably, the bracket is an annular structure, and is provided with a feed inlet and a discharge outlet corresponding to the groove.

[0008] Preferably, the driving assembly includes a connecting seat fixedly mounted on the rotating shaft, and an electrically connected time relay, controller, and motor are provided in the frame, and a rotating rod is fixedly connected to the output end of the motor, and a connecting disk that is transmission-connected to the connecting seat is fixedly mounted on the rotating rod.

[0009] Preferably, the rotating rod and the rotating shaft are horizontally arranged from top to bottom, and the rotating shaft and the connecting seat extend to a side position inside the frame.

[0013] 1. The utility model arranges a matching bracket and a turntable in the short pipe, and provides circumferentially distributed grooves on the turntable, so that the bracket can intercept the soluble tracer, and the soluble tracer in the groove can be quantitatively stored.

[0014] 2. The utility model uses a time relay to send instructions to the controller according to time, so that the controller sends a signal to the motor.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4, a soluble tracer delivery short connection, comprising a short connection pipe 1 and an oil pipe 2;

[0022] A bracket 3 is fixedly installed in the short pipe 1, and a turntable 4 is rotatably installed in the bracket 3. The turntable 4 is provided with six circumferentially distributed grooves 5 for storing soluble tracers.

[0023] The bracket 3 is an annular structure, and the bracket 3 is provided with a feed inlet and a discharge outlet corresponding to the groove 5. Figure 2 As shown, when the soluble tracer enters one of the grooves 5, when the turntable 4 rotates in the bracket 3, the bracket 3 can seal and intercept the soluble tracer in the groove 5, thereby ensuring that the weight of the soluble tracer entering the groove 5 is the same;

[0024] A feed pipe 6 for dispensing soluble tracers is provided in the short pipe 1. A connected frame 7 is fixedly installed on the short pipe 1, and a rotating shaft 8 connected to the rotating disk 4 is rotatably installed in the frame 7. The feed pipe 6 can discharge the soluble tracers. This technical solution is a prior art and will not be elaborated on in detail here.

[0025] A driving assembly for driving the rotating shaft 8 is installed in the frame 7;

[0026] The driving assembly includes a connecting seat 9 fixedly mounted on the rotating shaft 8, and an electrically connected time relay 11, a controller 12, and a motor 13 are arranged in the frame 7, and a rotating rod 14 is fixedly connected to the output end of the motor 13. The rotating rod 14 and the rotating shaft 8 are horizontally arranged from top to bottom, and the rotating shaft 8 and the connecting seat 9 extend to one side of the frame 7. The time relay 11 and the controller 12 can realize electrical connection and send an opening and closing instruction to the motor 13. This technical solution is a prior art and will not be elaborated on here.

[0027] A connecting plate 15 is fixedly mounted on the rotating rod 14 and is transmission-connected to the connecting seat 9. The connecting seat 9 is provided with circumferentially distributed positioning grooves 10, and a positioning rod 16 is fixedly mounted on the connecting plate 15 and is eccentrically arranged and extends into the positioning groove 10. The connecting seat 9 is provided with circumferentially distributed notches, and a convex plate corresponding to the notches is fixed on the connecting plate 15.

[0028] The motor 13 drives the rotating rod 14 to rotate, and the rotating disk 4 can rotate intermittently through the cooperation between the connecting disk 15 and the connecting seat 9. When rotating, the rotating disk 4 can drive one of the grooves 5 to correspond to the discharge port, so that the soluble tracer in the groove 5 can be discharged out of the short pipe 1 for operation, and the time relay 11 cooperates with the controller 12 to achieve timed and quantitative discharge of the soluble tracer. After extraction, the soluble tracer can evaluate the production inside the oil field, thereby improving the accuracy of the logging data.

[0029] The functional principle of the utility model can be explained through the following operation modes:

[0030] The oil pipe 2 is installed on the short pipe 1, and the oil pipe 2 drives the short pipe 1 to move in the oil field;

[0031] After the feed pipe 6 is opened, the soluble tracer falls into one of the grooves 5;

[0032] The time relay 11 sends a signal to the controller 12, and the controller 12 sends a command to the motor 13, and the output end of the motor 13 drives the rotating rod 14 to rotate;

[0033] The rotating rod 14 drives the connecting plate 15 to rotate, and the connecting plate 15 drives the positioning rod 16 to rotate. When rotating, the positioning rod 16 extends into one of the positioning grooves 10 and applies pressure to the connecting seat 9, so that the connecting seat 9 drives the rotating shaft 8 to rotate in the frame 7. When the rotating shaft 8 rotates, it drives the rotating plate 4 to rotate in the bracket 3. When the rotating plate 4 rotates, the groove 5 containing the soluble tracer can correspond to the discharge port, so that the soluble tracer is discharged from the short pipe 1 through the discharge port;

[0034] According to the signal instruction sent by the time relay 11 to the controller 12, the rotating rod 14 discharges the quantitative soluble tracer out of the short pipe 1 during the intermittent rotation process;

[0035] After the soluble tracer is dissolved, it is sucked into the oil pipe 2 for storage, and the oil and gas reserves and production of the oil and gas are evaluated by detecting the soluble tracer.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
