摘要
随着胜利探区勘探开发的逐步深入,主要勘探目标开始转向小断块、小砂体等微幅构造以及岩性隐蔽油气藏,传统的地震采集设计技术难以满足当前生产需求。为此,选取胜利探区复杂构造地质模型,开展基于波动方程理论的地震波照明和面向目标的观测系统优化设计技术的研究,形成了一套适合胜利探区二次采集的观测系统优化设计的技术系列。研究结果表明,该技术系列能够保证该区地质构造的形态完整,小断块、小砂体等微幅构造的成像质量也有较大幅度的提高。
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.
