吉林大情字井油田是一个具有多套含油层系的大型油田，主力油层为青山口组的青一段、青二段，青三段底部的11和12砂组及泉头组的泉四段地层。由于构造、岩性、地层水矿化度及工程等原因，使得流体性质识别难度较大。利用试油、生产资料和常规测井资料进行井点和纵向上流体的研究，提出了用声波时差 - 深感应电阻率交会图版和声波时差 - 深侧向电阻率交会图版定量识别本区流体性质的方法。

Daqingzijing Oilfield in Jilin is a large-scale oilfield with multi-pay zone systems. The major reservoirs are the first and
second members, the bottom of the third member of Qingshankou Formation, and the forth member of Quantou Formation. It is
difficulty to identify the fluid property in this area because of the structure, lithology, formation water salinity and
engineering. This paper proposed AC-RILD and AC-RLLD cross plot method to quantitatively identify the fluid property in
this area through the study of the well point and vertical fluid using testing, production, and conventional logging data.
