摘　　要：3DMove software, based on the three-dimension structural model of geologic inter- pretation, can forecast reservoir cracks from the point of view of formation of the structural ge- ology, and analyze the characteristics of the cracks. 3DMove software dominates in forecasting cracks. We forecast the developments and directions of the cracks in Chengbei buried hill with the application of forecasting technique in 3DMove software, and obtain the chart about strain distributing on top in buried hill and the chart about relative density and orientation and the chart about the analysis of crack unsealing. In Chengbei 30 buried hill zone, north-west and north-east and approximately east-west cracks in Cenozoic are very rich and the main directions in every fault block are different. Forecasting results that are also verified by those of drilling approxi- mately accord with the data from well logging, the case of which shows that the technique has the better ability in forecasting cracks, and takes more effects on exploration and exploitation of crack reservoir beds in ancient buried hill reservoirs.3DMove software, based on the three-dimension structural model of geologic inter- pretation, can forecast reservoir cracks from the point of view of formation of the structural ge- ology, and analyze the characteristics of the cracks. 3DMove software dominates in forecasting cracks.
