| In Xingshugang areas, oil and gas exploration is mainly in shallow layers. But now has entered the high water cut stage, the reserve-production balance outstanding conflicts outstanding and it is an urgent to find a viable alternative to the potential. In Xingshugang regions, there are several sets of Fuyu and Yangdachengzi oil and water mix layers, water-based identification difficult. Pyrolysis, chromatography, fluorescence microscopy images, nuclear magnetic resonance evaluation of oil-water layer recognition technology is mature, fairly effective and is fully equipped to accurately identify the conditions for evaluation of reservoir fluid properties,but all technology are not used in this regions,it is difficult to show the advantage of mud logging technology .We use mud logging technology for the production well to solve the problems of evaluation, and direct the completion of well, provide the information of next well location definition and regional reserve calculation, oil-water layer recognition technology based on sidewall core and core is used in this region, according to the regional condition, collect logging and testing data of the 40 wildcat and production wells, establish a way for oil-water layer recognition, create oil-water layer recognition standard and plate, and use it to new 30 wells, accordant degree increase up to 90%,this prove the correction of technology. Summed up a lot of practice by the water layer pattern recognition method, application to obtain good results, access to a huge economic benefits.
