水淹层发展动向（Development trend of water flooded layer） Water flooded logging technology is a kind of logging technology developed in 1950s. It is an important technique for detecting water cut and developing oil field water content and predicting underground remaining oil. At present, with the development of the technology for half a century, many technical series have been formed, which have become an important means for tapping the potential of remaining oil in the middle and late stage of high water cut oilfield development. The common water flooded layer logging natural potential logging, induced polarization potential logging, resistivity and dielectric logging and nuclear logging and resistivity logging. The complex resistivity logging technology is the current domestic oil often uses an advanced logging technology of water flooded layer. Logging techniques for flooded beds in oil enterprises Most of the oil fields in China are continental deposits, and the reservoirs are heterogeneous and lack of natural energy. China is one of the countries with high proportion of waterflood development in the world, and the reserves of water injection development account for more than 60% of the total reserves. Long term water injection development makes the water content of many oilfields relatively high. Taking Zhongyuan Oilfield as an example, more than 80% of the oil field is now in high water cut condition. The characteristics of high water cut, the remaining oil distribution is highly dispersed, high water and low water disorderly regional regional distribution, which increases the difficulty of tapping the potential of remaining oil adjustment measures, the effect of variation, also makes the adjustment wells wells to. In order to overcome these two difficulties, we must do a good job of controlling water and stabilizing oil. No matter what kind of countermeasures, the premise is to make clear the distribution of underground oil and water, determine the remaining oil enri
