Description

Technical Field

[0001] The utility model relates to the technical field of well logging equipment, in particular to an electric positioner for oil exploitation. Background Art

[0002] The water injection well in the oil field is a well used for oil field exploitation. Its function is to inject water into the oil field to increase the underground pressure, thereby pushing the crude oil to the production well (oil production well) and improving the recovery rate of crude oil. The water injection well is usually located around the oil production well. Its function is to inject water into the ground to form a horizontal surface, thereby forming a pressure driving force to push the crude oil to the oil production well. Water injection wells usually operate together with oil production wells, and their layout and injection water volume need to be carefully designed and adjusted to ensure the best oil production effect. In actual well logging work, due to the complex formation conditions in the drilling well, or accidents in the well team during drilling construction, the well deflection is too large, the hole is enlarged, the diameter is reduced, and the block falls. When logging, it is easy for the logging instrument to get stuck in the well. The current locator used in logging does not have an anti-stuck effect when in use, and when the instrument falls, the locator cannot fix the instrument in the well in time to limit its fall, affecting the later salvage use.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1-4As shown, an electric positioner for oil production proposed in one embodiment of the utility model can realize the positioning of instruments during well exploration operations, avoid accidental dropping of instruments, and prevent them from being placed horizontally in the well, resulting in jamming and inconvenience in salvaging and use, thereby improving the use effect. The utility model comprises a positioner rod body 1 and a positioning member 3, a connector 2 is fixedly connected to the positioner rod body 1, a positioning member 3 is cooperatively connected to the positioner rod body 1, the positioning member 3 is cooperatively connected to an electromagnet push rod 4, the electromagnet push rod 4 is cooperatively connected to the positioner rod body 1, the electromagnet push rod 4 is cooperatively connected to a rebound member 5, the rebound member 5 is cooperatively connected to the positioner rod body 1, and the device The device is electrically connected to an external control device through a conductive line, and the operating state of the device is controlled by the external control device. The well exploration instrument is connected to the bottom connecting seat 202, so that the cable passes through the interior of the locator rod body 1 and the connector 2. The push rod body 401 is hollow in design, so the cable can pass through successfully. The top connecting seat 201 is connected to the external traction head. When the instrument is in well exploration operation, the push rod body 401 is energized. When energized, the push rod body 401 will slide inside the locator rod body 1, so that the second sliding frame 402 shrinks toward one end of the bottom connecting seat 202. At this time, the spring 502 is squeezed and shrunk to maintain the rebound force. Since the first sliding frame 301 The spacing between the second sliding frame 402 and the second sliding frame 402 is increased, and the combined outer support diameter of the first rotating rod 302, the inner support rod 303 and the second rotating rod 304 is reduced, so that the positioning device can be operated downward in the well. When the instrument needs to be positioned, the power to the push rod body 401 is disconnected. At this time, the spring 502 rebounds, and the second sliding frame 402 can slide toward one end of the top connecting seat 201. At this time, the spacing between the second sliding frame 402 and the first sliding frame 301 is reduced, thereby increasing the combined outer support diameter of the inner support rod 303, the inner support rod 303 and the second rotating rod 304. The inner support rod 303 contacts the inner wall of the deep well, which can realize the fixed use of the inner support and play a role in positioning together. When the instrument is used in the deep well, there may be an accidental disconnection of the cable and the connector when the instrument is lowered into the well, causing the instrument to fall off. Since the instrument is connected to the bottom connecting seat 202, when the cable is accidentally disconnected, the push rod body 401 loses power. Therefore, the push rod body 401 can slide toward one end of the top connecting seat 201 under the rebound force of the spring 502. At this time, the inner support rod 303 can be supported outward to contact the inner wall of the deep well to prevent the instrument from continuing to fall, thereby preventing the instrument from falling horizontally inside the deep well, causing it to get stuck and affecting the subsequent salvage operation. The use effect of the locator is improved by design.
