【摘要】This paper presents an overview of petrophysical research and exploration achievements of low resistivity pay (LRP) zone by well logs in China. It includes geological characteristics and characteristics of well log response of the low resistivity pay zones discovered and evaluated in recent years,as well as the problems in recognizing and evaluating low resistivity pay zones by well logs. The research areas mainly include the Neogene formations in the Bohai Bay Basin,the Triassic formations in the northern Tarim Basin and the Cretaceous formations in the Junggar Basin. The petrophysical research concerning recognition and evaluation of the low resistivity pays,based on their genetic types,is introduced in this paper. 【总页数】8页(41-48)
