Three-Dimensional Tectonic Interpretation And Reservoir Seismic Prediction In The Middle Part Of Es3 In Linpan Area

Panhe area is the main oil production area of Linpan oilfield,an area of about 180 square kilometers.The structure of this area is extremely broken,which is the most complex area of the whole Linyi sag,and the extremely fragmented structure also has a large potential for rolling exploration.However,with the deepening of rolling exploration work,the potential of high-precision information is getting less and less,the actual work exposed much more problems.Panhe gold triangle are very complicated by the geological characteristics of the constraints,the development of many small faults,Small fault block and fault system,which leads to the inaccurate understanding of the sedimentary characteristics and reservoir distribution in this area,and it is difficult to find favorable oil and gas target.Aiming at the problem that the seismic reflection continuity is poor and the significant reflection interface is lacking in the study area,the low frequency data is filtered by the frequency division interpretation method,and the high frequency seismic data body is obtained to guide the interpretation of the unclear region.At the same time,according to the extremely complex situation of the fault area in the study area,the faults of different grades are identified by forward modeling,attribute slicing and inclination detection.On the basis of structural explanation,the macroscopic depositional environment of the work area is analyzed.The principle of sedimentation compensation is used to analyze the archaeological landform and provenance analysis,that the north and southwest as the main source direction;The constrained sparse pulses and genetic inversion are used to forecast the distribution of reservoirs in the middle Es3 of the study area;Based on the final inversion results and the pre-seismic attribute characterization,the distribution of reservoirs in the study area is analyzed and summarized.On the basis of structural interpretation and reservoir prediction,two favorable exploration targets are proposed.
