Study On Seismic Interpretation Method Of Complex Tectonic Zone In GaoYou Sag Of Subei Basin

Enhances year by year along with the oil gas exploration degree in GaoYou sag,Explores the region gradually to the structure complex stave area shift, seeks the deformational trap to be day by day difficult, Explores under sternly the situation in this, the present paper in the appraisal master stratum seismic datum quality and in the summary structure interpretation difficulty foundation, has with emphasis carried out complex structure belt seismic interpretation method research in GaoYou sag. First to the horizon, the fault and the velocity research core explained the work has developed each kind of technical serviceability and the valid analysis research,the research and optimal suits three kind of main horizon calibration technology which the current exploration needs, summarized the complex structure belt seismic horizon interpretation basic work flow, the research and the optimal five effective seismic horizon interpretation method,developed the fault model to develop the research, the research and the optimal four kind of profile and six kind of plane fault interpretation technology,in high postal velocity profound analysis foundation, in research and optimal two kind of actual variable-velocity structure mapping method. In above core technologies solid research foundation, has carried out the seismic integrated interpretation method research in view of three kind of difficult area in GaiYou sag, in the structure style foundation summarizes GaoYou sag main structure which in the system which to take to bring with the fault style, the profile characteristic and structural forms, has studied under the geological pattern instruction complex fault zone structure interpretation method, in the research foundation to the igneous rock invasion model, studied and summarized the igneous rock growth area structure interpretation method,has developed to forward modeling of the minor fault response, studied and summarized the igneous rock growth area structure interpretation method. The research results promotion applied in the actual exploration of GaoYou sag, has carried out one batch of advantageous drilling goal, and submitted one batch to prospect, drilling effect obvious, has safeguarded three level of reserves completions in GaoYou sag. The present paper will have the very good instruction and the model significance to other local seismic interpretation work.
