[Abstract]:The Putaohua reservoir, which is the main reservoir in Songliao Basin, is developed in the first member of the Yao formation. Gulong Oilfield spans two secondary tectonic units, Qijia-Gulong Sag and Longhu Po-Da 'an terrace, the main body of which is located in the north-south syncline structure of Taikang uplift and Daqing Placanticline. The overall tectonic trend is low and high on both sides of the middle. Block 59 is located in the southeast of Gulong Oilfield. By studying the structural characteristics of Putaohua formation in Gu59 block of Gulong Oilfield, it is not only beneficial to oil and gas exploration and development in this area, but also of practical significance to oil and gas exploration in the south of Daqing Placanticline. Based on the analysis of the original data, the combined static correction with surface model constraint is used to solve the problems of static correction, improving resolution, protecting effective signal, eliminating the difference of longitudinal and transverse energy and migration imaging. The techniques such as multi-domain amplitude preserving de-noising, surface consistency amplitude compensation, two-step ground consistency deconvolution and prestack time migration in the prestack region are obtained. The new processing results show that the target layer has strong reflection energy, high signal-to-noise ratio (SNR), obvious wave group characteristics, abundant information between layers, obvious structural features, clear fracture points and clear sections. Based on the theories of structural geology, sedimentology, petroleum geology and so on, on the basis of summing up the previous research results, this paper synthetically utilizes the data of 3D earthquake, geology, logging, core and so on, and selects 56 wells in the working area. Through strict quality control, artificial synthetic seismic records were made to calibrate the Puyi oil reservoir group, through the calibration of the seismic geological layer, the seismic reflection characteristics of each geological layer in the area were determined. After repeated stratigraphic correlation, Combined with seismic profile characteristics, according to seismic reflection characteristics of Gaohua formation calibrated by well earthquake, fine structural framework was built. Based on this, according to the standard section, the whole area of target strata and faults were interpreted by tracing correlation. The variable velocity mapping method of fixed v0 and variable p is used to obtain the velocity field in three dimensional space, and the time-depth transformation is carried out, and the structural map of grape flower reservoir is compiled. On the basis of compiling the structure map of the top and bottom interface of the sand formation of the Putaohua reservoir, the formation thickness map of each sand formation has been completed. Seven traps with an accumulative area of 25.29 km ~ 2 were identified, and four types of traps were divided into four types: fault block, back fault, fault nose and anticline, mainly faulted nose and block trap. There are 63 faults in the area, mainly normal faults, the strike of which is mainly NW and NNW, and NNW extends longer than NW, NW is relatively short. The fault is mainly developed from Nenjiang formation to Qingshankou formation with graben and barrier in longitudinally, and the NW-trending fault cuts NNW and NNE faults on the plane, and the NW-trending fault develops relatively early.
