The utility model discloses a remote real-time monitoring system for well drilling construction. The remote real-time monitoring system consists of a data collecting terminal, a data transmitting part, an application server and a client, wherein the data collecting terminal transmits parameter information of a well drilling site to the application server by the data transmitting part for the client to call, process and display. The remote control client comprises browser-based display software and independent client software; a web server is accessed by the network, the data of a data base server can be extracted after the client identification is verified, and the data can be displayed in real time at the client. The information of the well drilling site is transmitted to the rear part by the network in real time, so as to be in favor of forming networked construction decisions of a directional well, so that full interaction among a directional well engineer and a geological engineer on the site as well as supporting personnel and decision makers at the rear part can be realized. The remote real-time monitoring system provides convenience for the design and construction processes of the directional well and a horizontal well, thereby realizing flexible and convenient track design and track control of the directional well and reducing the occurrence probability of accidents at the well drilling site.
