Abstract： Domestic gas drilling construction process has begun to use microwave relay transmission mode to build monitoring while drilling system. However, the supporting LWD monitoring software applied in this construction condition is not mature, the data analysis time is long, the measurement transmission rate is low and there is no channel monitoring function, which restricts the development of gas drilling. According to the actual needs of gas field, this design adopts event driven software architecture to develop supporting MWD monitoring software, which can conduct human-computer interaction of various engineering parameters in the process of gas drilling in various ways such as curve, value, scale, etc., and can supervise microwave channel in wellbore, which provides software support for real-time monitoring while drilling and post drilling analysis and research of gas drilling. Moreover, the application of the software greatly improves the test transmission rate of the monitoring system, and the maximum measurement transmission rate reaches 1.194 kb/s. The introduction of channel monitoring function can increase the number of microwave repeaters entering the well and make the logging transmission depth exceed 3 000 m, which basically meets the needs of current gas drilling while drilling monitoring.
