Integration and Integrated Analysis of the Methods of Exploration Geophysics for Searching Oil and Gas Deposits

摘要

The essence of the work lies in the complexing of exploration geophysics methods with the purpose to search for oil and gas. At the first stage of work the rapid forecast of hydrocarbon deposits (HC) was completed in the Cenomanian deposits on potential fields. In the interpretation system (IS) PANGEA the integrated analysis of the gravitational and magnetic fields was conducted. The territory of the Yamal Peninsula is covered with a regular network of regional seismic profiles. When comparing the abnormal area with the crossing of its regional profiles on time section anomaly seismic record in the form of an area with absolutely horizontal axis in the phase of a reflector was detected. Thus the gas-water contact (GWC) displays on the time section in the geological interpretation. After reprocessing and reinterpretation of seismic areal works, on which the abnormal region from the map perspectives gets, the GWC is clearly began to beat from the alleged Cenomanian deposit on time sections. Thus, the first works on the integration of different methods of field geophysics gave a good result. The further forecasting of the deposits by this technology will continue.
