At present,China's economy is developing rapidly,and the application of oil and natural gas energy in various aspects is increasing.With years of research and exploration,China's conventional oil and gas reservoirs are becoming less and less,which makes us turn our eyes to the application and research of fractured oil and gas reservoirs.Is not the same with conventional reservoir properties of reservoir rock properties change is bigger,in terms of lateral seepage physical properties such as reservoir space and also each are not identical,and the cracks between the different development situation,filling in the cracks of the material is also different,these differences have a huge impact on fracture reservoir prediction work,enables the fracture reservoir prediction work there is considerable difficulty.In the current production and development,we find that the study of fractured reservoirs will have errors if using a single research method,which requires the study of a variety of methods to compare,give play to the advantages of various methods,comprehensive prediction research and analysis of the working area to get more accurate prediction results.This paper mainly studies the carboniferous fractured reservoir in the east wing of chepaizi.Due to the complex geological conditions in the working area and the relatively scattered reservoir block divisions,the conclusions drawn by a single research method are difficult to be convincing.Therefore,a variety of methods suitable for the working area should be selected for comprehensive prediction.We have successively selected the coherence volume fracture prediction technology,ant tracking technology and texture analysis technology to predict the fracture of the work area,and the comparative analysis of exploration results in the work area have a good correspondence.We conclude that the coherence volume technique has a high resolution in longitudinal direction and can control geological bodies well in depth.Ant tracking technology has a good effect on the detection of oil and gas reservoir blocks due to the characteristics of ant body clusters,but it is difficult to accurately divide a point or a small area with ant tracking technology,which is also the disadvantage of this technology.Texture analysis technology is aimed at the analysis of small faults and cracks as well as small structures in the work area.On the advantages and disadvantages in the work area of the three methods of comprehensive evaluation more accurate results are obtained.
