In Xing shu gang oil-field, low permeability, weak physical characteristic, high content of clay cause serious formation damage. On research of the study of low permeability formation and damage characteristic of Xing shu gang oilfield, we acquire why the injection wells have problems of little hygroscope thickness and low hygroscope capacity.

But it has more complicated velocities in the working area, and it locally develops high-speed boulder bed in neocene Xiyu Formation with a velocity 3700—4050m/s, its adjacent formation velocity: 2800—2900m/s; while it also develops low velocity gyprock that has a great variation in thickness (with an increasing thickness from south to north) with a velocity about 4000 m/s, its adjacent formation velocity: about 5000 m/s. And all this is the cause of the complexity of the velocity in this working area; thus to make the No.1 structure in northern YK reliable, in velocity modeling it has much research work to do, and it is also the topic of this graduation thesis.
