Oil and gas production intelligent monitoring system and method based on NB-IoT

Abstract

The invention provides an oil and gas production intelligent monitoring system and method based on NB-IoT and relates to the oil and gas monitoring technology field. By using the system and the method, data acquired by various digital instruments are transmitted to a cloud server through an advanced NB-IoT wireless communication module at regular intervals by a controller in an oil and gas production field; and a transmission protocol type adopts CoAP, definition and deployment of profile and encoding and decoding plug-ins are completed by the cloud server in advance, the data transmitted by the NB-IoT wireless communication module are analyzed and stored, a client program of an upper computer captures the data from cloud, and oil and gas well attribute data monitoring values are displayedto a user. When the monitored data is abnormal and reaches an alarm value, a manager can send a work stopping instruction to a main controller at an upper computer end, takes the cloud as a relay, and stops working of a generator through controlling the relay so that work of a well site kowtow machine is stopped, and low power consumption and high stability in an oil and gas production monitoringprocess are achieved.

Description

technical field [0001] The invention relates to the technical field of oil and gas monitoring, in particular to an NB-IoT-based intelligent monitoring system and method for oil and gas production. Background technique [0002] Coalbed methane wells are rich in resources. The important parameters of these coalbed methane wells (such as downhole pressure, wellhead pressure, pipe pressure, casing pressure, water yield, downhole temperature, wellhead temperature, and generator voltage and current, etc.) are currently passed through the GPRS / GSM communication protocol. For data transmission, such a communication network has high power consumption, high cost, small access volume, poor signal, and relies on mobile companies, especially in some project departments with low production capacity and low profit. High cost, the above data all require people to collect, patrol wells, and read meters. Especially in bad weather conditions, well patrol work becomes more difficult, and the la...
