便携式井场通讯装置研制

Development of portable communication device for well site

针对我国目前钻井工程作业现场工况，研制了一种便携式通讯装置。该通讯装置采用单工调频超短波通话对讲，工作频率有３０ＭＨｚ、１００ ＭＨｚ、１３８ＭＨｚ三种，通讯距离可达１ｋｍ。该装置体积小、携带方便，不仅用于油田钻井工程作业现场通讯，还可应用于其它行业短距离通讯，具有较高的实用价值和广阔的应用前景。

Accolding to the requirement of drilling operation, a portable communication device has been developed. It works in the manner of ultrashort wave of half-duplex modulation frequency. The frequency of ultrashort wave is 30 MHz. 100MHz and 138 MHz selectively. Its communication distance can reach 1000 m. The device has small size and can be carried easily. It can he used in the well site and other fields for short distance communication. It has the higher application value and prospect.
