Application Background

China's oil resources are relatively scarce, and many domestic oil and gas fields are limited by oil and gas resources reserves, with small production capacity and low recovery rate, resulting in a large amount of crude oil has been imported for a long time, therefore, raising the production yield of oil and gas wells and improving the recovery rate of oil and gas wells has become the key to the long-term energy strategy without delay.

Numerous domestic oil and gas wells need to adjust the oil exploration plan based on the dynamic variation of the well environment parameters to improve the recovery rate and production yield; thus, the remote monitoring system of oil and gas wells has become crucial to improve the exploration and exploitation of oil and gas wells. During the exploration and exploitation, the parameters of information pressure, fluid level, and density are also vital in detecting whether the wells are normal or not.

Application System Overview

The intelligent oil well remote monitoring system adopts a centralized monitoring structure, mainly consisting of a centralized control center, 4G RTU, and metering instruments (pumping machine control cabinet, pressure transmitter, temperature transmitter, wireless power indicator, etc.). The mechanical equipment of each oil well and the central production scheduling & command system platform are connected into an oilfield-specific internet to realize automatic data collection and remote control of the oil well, as well as unified scheduling and intelligent management of oil well production.

Application Case Overview

In the offshore oil and gas exploration and exploitation project of COSL, MICROSENSOR provided integrated services for customers by cooperating with COSL's professional oilfield such as geophysical prospecting, drilling, and logging, which significantly satisfied customer's demand to lower operating costs, shorten operating time, decrease operating risk, and increase the economic benefits.

In the process of exploration and exploitation, accurately knowing whether there is oil underground, the depth of the oil layer, the area covered by oil, oil reserves, and the allowable extraction range, etc., is necessary by measuring the formation pressure, fluid density, temperature, etc. to determine the fluid properties, and further to judge the actual production status of the well and the quality of oil products. Moreover, because of the unknown formation pressure in the drilling process, various degrees of overflow or blowout accident occurs. Therefore, it is critical to monitor in real-time the variations of parameters such as pressure, level, density, and flow rate of mud during the drilling process, and then to detect drilling abnormalities in time and take effective measures to prevent and control them, which is essential to reduce the occurrence of complex accidents downhole.
