针对胜利油田开发阶段不同研究区块所要解决的精细地质问题，以地质对比剖面为依据，研究了井间地震剖面上地质体的地震反射特征；并根据各区块的综合研究成果，建立了井间小断层、火成岩蚀变带、砾岩体内幕、三角洲分流河道砂等4个典型地质目标的精细井间地震地质解释模式，建立了利用井间地震资料研究精细地质目标的解释流程。利用该解释流程对莱1区块的小断层进行了识别，对罗151区块的火成岩蚀变带的发育情况作了解，对永1区块的岩体内幕进行了描述，对樊124区块的三角洲分流河道砂体作了解释。实际应用表明，该解释方法实用有效。

From seismic crosshole data of 23 pairs in Shengli oilfield and on the basis of fine geologic correlation, the seismic reflective features of subtle geologic body are described on seismic crosshole sections to solve complicate geological problems in different blocks at different development periods. The interpretation plates of seismic crosshole in four typical blocks are established which can identify cross-hole small faults, erosion belt of volcanics and conglomerate dope, delta distributary channel sand etc. The interpretation method to identify fine geologic targets on seismic crosshole data is formed by referring to the interpretation workflow of normal seismic data. This has made solid foundations for deepening geologic realizations and reconstructing reservoir geologic models. Finally, according to the current development situation of Shengli oilfield and the priority of seismic crosshole technique, the wide application prospects in reservoir development are discussed in three aspects.
