Embodiment Construction
[0052] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0053] Due to the following problems in the current control method of the downhole detection device: the signal of the cable line connected to the downhole detection device attenuates with the increase of the distance, and the communication is blocked. Moreover, the downhole detection device goes deep into the well, so it is difficult to supplement the electric energy and it is diffic...

The invention provides a downhole detection device and a charging system. The system comprises a short downhole control section arranged on the portion, corresponding to a downhole detection end, in awell, a short downhole detection section installed on the portion needing to be detected in the well and used for receiving an energy-carrying control signal transmitted from the ground, charging thedetection device, controlling the operating state of the detection device, and transmitting information detected by the detection device to the ground, wherein the position of the short downhole control section is adjusted so that the short downhole control section can transmit the energy-carrying control signal to the short downhole detection section to control the operating state of the detection device, and meanwhile, the short downhole detection section can transmit a detection signal to the short downhole control section. The system reduces the difficulty of electric energy supplement, the detection device can be supplied with electric energy without dismantling from the short downhole detection section, and downhole actions can be adjusted in real time according to downhole detection parameters.
Description
technical field [0001] The invention relates to the field of automatic control of oil wells, in particular to an underground detection device control and charging system and method. Background technique [0002] Most of my country's oil fields have entered the late stage of development, and the downhole oil layer pressure has decreased, making oil extraction more difficult. It is necessary to perform water injection operations on the formation to increase the pressure, and the water content rises rapidly. Due to the difference in permeability between layers, high Oil layers with medium and low permeability are different from each other in terms of water absorption capacity, waterline propulsion speed, formation pressure, oil production rate, water flooding, etc., resulting in prominent contradictions among oil layers and serious interlayer interference. Therefore, it is necessary to The downhole injection-production relationship is further subdivided. However, the condition o...
