M凹陷中生界基底侵入岩发育, 分布广, 与油气储藏有一定的关系。搞清侵入岩体的分布形态与赋存, 对凹陷下一步的勘探工作部署和油气综合评价是有意义的。本文应用磁重震综合物探方法技术有效地确定了基底侵入岩的形态与分布, 为地震解释、钻井布置、油气综合评价提供了重要资料, 取得好的地质效果。

The intrusive rocks in Mesozoic basement of the M depression are well developed and distributed extensively. They have a certain relation with the oil and gas storage. To make clear the distribution pattern and occurence of intrusive rock mass is of significance for the next exploration work arrangement and hydrocarbon comprehensive evaluation. In this paper we employ the magnetic, gravity,and seismic methods and effectively determine the shape and distribution of basement intrusive rocks.These provide important data for seismic interpretation, drilling arrangement and hydrocarbon comprehensive evaluation. As a result, a good geological effect is obtained.
