张树林 .近海多波地震技术及在高温、高压气藏勘探中的应用 .石油地球物理勘探 ,2 0 0 1,36 (5 ) :5 6 3～ 5 71 多波地震技术是进行海上油气勘探和开发的一种十分有效的新技术。本文通过对超高温、超高压的莺歌海盆地岩石弹性物性的研究 ,发现纵横波速度比和泊松比对地层的岩性和含流体性非常敏感 ;在此基础上 ,根据泊松比并结合纵横波波阻抗 ,制作了莺歌海盆地和琼东南盆地中、深层的岩性和气层预测量板。应用这一预测量板和多波地震资料对 L D8- 3构造进行了岩性和气藏预测。预测结果表明 ,L D8- 3构造中、深层存在多套气层 ,且储层面积大 ,预测储量可观 ,从而预示了L D8- 3构造中、深层具有很好的勘探前景
Multi wave seismic technique is new and very effective technique for marine oil exploration and development. Through study of elastic petrophysical rule in Yingge Sea Basin with super high temperature and superpressure, the paper discovered that the velocity ration of P wave and S wave and Poisson ration is very sensitive to lithology of bed and fluid content; on that basis, the template of predicting deep lithology and gas bearing bed in Yingge Sea Basin and Basin of southeast of Hainan Island has been made according to Poisson ration and combining the wave impedance of P wave and S wave seismic data to predict lithology and gas reservoir for LD8 3 structure. Prediction results showed that there are multi sets of gas reservoir in deep of LD8 3 structure which have large reservoir area and considerable prediction reserve, so that it indicated a good exploration prospect in deep of LD8 3 structure .
