Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] Such as figure 1As shown, a wireless-controlled intelligent downhole sampling system is composed of a sampling device body (1), a wireless remote control device (2), a splash-proof sampling cup (3) and a fixed rod (4). The sampling device body (1) in the system is composed of an upper joint (11), an intermediate connecting body (12), a sampling barrel (13) and a lower joint (14). The parts of the sampling device body (1) are connected by threads. O-ring sealing; fixed rod (4) is long cylindrical.

[0044] Such as figure 2 As shown, the upper joint (11) of the sampling device body (1) is composed of an installation positioning groove (111), a temporary fixing hole (112), a convex switch (113) and a side hole (114). The upper joint (11) is divided into upper and lower parts, the upper part is a solid structure with installation positioning grooves (111) and te...

Abstract

An intelligent wireless control well sampling system belongs to the field of digital oilfields. The system is composed of a sampling device, a wireless remote control device, an anti-splash sampling cup and a fixing rod. The sampling device is composed of a top connector, a middle connection member, a sampling barrel and a lower connector which are in threaded connection. The wireless remote control device is composed of a remote control antenna, a power switch, a buzzer, an indication light and buttons. The anti-splash sampling cup is composed of a cup lid, an oil-taking connection hole, a ventilation hole, a sampling cup body and a scale. When the system is used for sampling, the fixing rod is inserted into a temporary fixing hole of the top connector for starting a power supply of the sampling device, a sampling mode of the sampling device is set remotely through the wireless remote control device, the anti-splash sampling cup is mounted on the sampling device after the sampling is complete, and the wireless remote control device is used for completing the sample transfer. The intelligent wireless control well sampling system is simple in structure, easy to mount and operate, high in flexibility and flexible in control mode and can be placed in a well for long term.

Description

technical field [0001] The invention relates to a wireless-controlled intelligent downhole sampling system. The sampling system is composed of a sampling device body, a wireless remote control device, a splash-proof sampling cup and a fixed rod. Specifically, it is a system that uses wireless technology to control the sampling system, and performs sampling and sample transfer. It belongs to the field of digital oil field. [0002] technical background [0003] As the development of my country's oil and gas fields enters the middle and later stages, more and more attention has been paid to how to improve oil recovery efficiency and reduce production costs. At present, oil fields are divided into high-production wells and low-production wells according to the distribution of oil wells and the different liquid storage volumes of oil wells. Especially for the "three low" oil and gas wells with low pressure, low permeability, and low production, when the liquid supply in the well...
