這是一種坐鍵式可打撈的正脈沖無線隨鉆測斜儀，做到了井口投放井底打撈，測量準(zhǔn)確，使用方便。儀器采用了經(jīng)實(shí)踐檢驗(yàn)成熟可靠的正泥漿脈沖技術(shù)，并在地面部分使用無線電傳輸立管壓力信號(hào)及其他數(shù)據(jù)參數(shù)，使用時(shí)不需要布置電纜，方便簡潔。井下部分短節(jié)之間也采取無線通訊，連接操作方便，解決震動(dòng)過程中傳統(tǒng)插針結(jié)構(gòu)帶來的隱患。
This is a retrievable Mud Pulse MWD, which can be dropped at the top of the well and retrieved from the bottom of the well. The instrument uses mature and reliable positive mud pulse technology and transmits stand pipe signals and other parameters by radio on the ground. When using, it does not need to lay out cables. The down-hole modules communicate wirelessly and the connection is easy and convenient, avoiding the hidden trouble arising from traditional contact pin structure during vibration.
