摘要

In recent years, three-dimensional seismic acquisition was carried out in Jiyang depression, even second-round three-dimen- sional seismic acquisition was completed in some complex oil and gas blocks and many complex media and small fault block reservoirs were studied. As a result, the oil and gas production in the Shengli oil field has been steadily growing. However, it is difficult for the traditional seismic acquisition design technology to meet the current production requirements, and hence the authors selected the steep slope belt of the Shengli exploration area to build velocity model and form a set of observation system optimization design technological series suitable for the second-round Shengli exploration district collection through the seismic wave illumination and object-oriented geo- metric optimization and design technology research based on the theory of wave equation. The research results show that the technologi- cal series can ensure the integrity of the form of steep geological structure and the improvement of the imaging quality of micro structures such as minor fault blocks and small sand bodies.
