为了完成油气检测任务,我们在TDI井进行了VSP测量,并对反射纵波和PS转换横波资料进行了处理。利用分辨率高的PS横波剖面查明了储层底界和井旁小断层;在联合应用纵、横波资料直接检测油气,查明井旁细微构造及研究碳酸盐岩地层裂隙等方面也取得了好的效果.

In order to accomplish the task of oil/gas detection,wa’ ve made the VSP measurement in Well Tiandong-1 and the data-processing has also been made for the reflected P-wave and the converted PS-wave. The bottom of the reservoir and the small faults near the well have been found out by using thePS-wave of high resolution. In oil/gas direct detection,in by-well small faults assertion as well as in carbonate fissure researching,good results have also been achieved.
