Problems solved by technology

[0004] 1. Indication error: The existing scheme determines the scale through the short-distance vertical displacement of the valve stem, which is limited by the stroke of the vertical displacement. The scale on the scale sleeve is not linearly distributed, and can only be estimated by several marked readings. , resulting in a large indication error
[0005] 2. Reading error: The operator reads the oil nozzle scale through the head-up scale sleeve and the lower edge of the valve wheel end cover. The slight position or line of sight deviation of the same operator will cause reading differences. This rough reading of the oil nozzle scale The way, the disadvantages are more obvious when different operators read, and the reading error is larger
[0006] 3. Unable to monitor online: the existing scheme can only be read on site, and the scale of the nozzle cannot be monitored in real time, especially in the production of typhoon mode, personnel are remotely monitored on land, and the site cannot be inspected, and the drift of the nozzle can only be fluctuated by some parameters Simple judgment cannot provide an effective basis for emergency response, and may even cause production stoppage or even more serious consequences

Abstract

The invention discloses a Christmas tree oil nozzle reading device and system. The Christmas tree oil nozzle reading device comprises a fixing device fixed to a valve hand wheel, a transmission deviceconnected with the fixing device, a field display device connected with the transmission device and a bearing device used for bearing the transmission device and the field display device. When the valve hand wheel rotates, the transmission device can be driven to rotate through the fixing device, and then the field display device is driven to display the rotating scale of the valve hand wheel. The Christmas tree oil nozzle reading device and system have the beneficial effects of being high in measuring precision and reliability, high in automation degree, convenient to operate, accurate in field indicating value and field reading and the like, and are suitable for precise reading and automatic monitoring of Christmas tree oil nozzles.

Description

technical field [0001] The invention relates to oil and gas exploitation engineering, in particular to a reading device and system for christmas tree nozzles. Background technique [0002] In oil and gas exploration and development, it is necessary to throttle and reduce pressure through the oil nozzle of the Christmas tree and then enter the downstream production process system. The nozzle is an indispensable component for the production of oil and gas wells. The production of the well is convenient for the daily management of the oil and gas well and the adjustment of the working system. In the existing production process, it is necessary to record the choke scale, downhole data, production situation, etc. as the basis for single well dynamic analysis. [0003] In the prior art, the design schemes for the readings of the oil nozzles of each Christmas tree manufacturer are relatively simple. Usually, a scale sleeve is used or the scale is directly marked on the valve stem ...
