辽河地区测量地层电阻率,最初用横向测井,后来用感应测井。一九七四乍,江汉研制的SCX—731型三侧向测井仪在辽河地区进行试验。七五年,三侧向正式投产,成为测量地层电阻率的主要手段。三年来,已测井五百多口,在判断油气层、确定地层参数等方面,起了重要作用。 Liaohe area formation resistivity measurement, initially with horizontal logging, followed by induction logging. In 1974, the SCX-731-type lateral logging tool developed by Jianghan was tested in the Liaohe area. In 1975, the three sides formally put into operation, as the main measure of formation resistivity. Over the past three years, more than 500 wells have been measured and played an important role in determining oil and gas layers and determining formation parameters.
