SK-OLM Online Wellbore Liquid Level Monitoring System



SK-OLM online wellbore liquid level monitoring system is a high-tech product developed by Shanghai Shenkai Petroleum Technology Co., Ltd. This product is mainly used to test the depth of the downhole liquid level, especially in the unattended environment on site, to automatically monitor the downhole annular liquid level and wellhead casing pressure, and provide reliable field data for analyzing the downhole liquid level changes and taking effective measures. This system uses advanced computer, signal processing and local wireless data transmission technology, as well as a precisely designed micro air gun wellhead sound device.


The equipment has the characteristics of integrated monitoring, small size, light weight, simple operation, friendly human-machine interface, low power consumption, and powerful functions.



Instrument features
The integrated liquid level monitoring and overflow alarm system for logging and drilling solves the defects of logging and liquid level measurement, forms complementary advantages, and provides scientific and verifiable measures for well control;

Continuous measurement can speed up the test frequency as needed;

Provide a nitrogen supply system to solve the nitrogen consumption cost and transportation problems;
After one installation, avoid the safety risks caused by frequent opening and closing of valves and wells, especially the human safety risks in emergency situations, such as forgetting to restore the state;

Real-time recording and monitoring of drilling safety, remote transmission of data, make up for the lack of timely grasp of liquid level dynamics, and have more advantages in forecasting abnormalities;

Indoor operation and monitoring reduce safety risks;

Take into account traditional test methods;

Open-end measurement does not delay drilling construction;

Develop WITS data interface to provide input and output functions.
