Abstract: To achieve the purpose of digital transformation and intelligent development of oil and gas enterprises under the background of international low oil price, improving production efficiently is an important strategy for the sustainable development of these enterprises. The acquisition and transmission of gas well production data is an effective method to early warning dynamic analysis and reduce labor intensity. The traditional scheme of data acquisition and transmission is of high cost, long construction period and high equipment power consumption, which is not a good for remote and inefficient gas wells. In this paper, through the research of Low Power WAN (LPWAN) technology, we summarized the technical advantages, and by combining with the production characteristics of remote and inefficient gas wells, the environment and information requirements, we accomplished an economic and reliable data transmission scheme based on Lora and NB-IoT heterogeneous networking. The scheme uses sensors to collect production data of gas well and transmit it to acquisition and transmission module through LoRa technology. After analysis, it is transferred to cloud server through NB-IoT technology. The control center can realize remote monitoring by visiting cloud server. According to the test and analysis of the scheme in this paper, the results show that the scheme can realize the data acquisition and transmission of remote and inefficient gas wells with high efficiency, low cost and low power consumption, which provides an effective supplement to the traditional information construction scheme.

Key words: low power, remote and inefficient gas wells, long distance transmission, reduce cost and increase efficiency
