Research on the Comprehensive Utilization of Geophysical History Data to Achieve High Definition Prediction of the Remaining Oil
The high definition prediction of reservoir remaining oil relies on the re-acquisition of geophysical data which need more ground acquisition facilities.Then they not only increase the investment but also aggravate the destruction of surface ecological environment.A lot of geophysical history data has been accumulated during the decades of the development of oil fields,but the data usually came from different acquisition methods, such as the seismic data acquired from ground surface seismic and the resistivity and the acoustic data acquired from well logging in boreholes.Even though the acquisition method is same, the update of acquisition facility resulted in some questions such as data mismatch.Take the north producing region of Daqing oil field as the research target, which has been developed for nearly sixty years.Firstly, establish the reconstruction method of borehole early stage ordinary resistivity and the present lateral resistivity.Secondly, establish the reconstruction method of the Pseudo-acoustic curve by using the borehole resistivity data.Thirdly, perform the joint inversion between the borehole data and the seismic data from ground surface to obtain the definition prediction result of remaining oil.The research method is of great significance on finding remaining oil and saving money for the developing oil fields.
