Recovering denudation thickness by interval transit-time
FU Xiao-fei,et al.(Daqing Petroleum Institute,Daqing 163318,China)
By analyzing the principle of the method of recovering the denudation thickness by interval transit-time and its application situation,the author thinks that the method can be used to solve the problem of denudation after the end of K_1n.The calculation result shows that the difference of the denudation thickness of the unconformity of different areas at the end of K_1n is very obvious:Dong 1 and Dong 402 areas in Suihua Depression have much large denudation thickness and it decreases towards the direction of Dong 6 and Dong 7,the denudation thickness of Shuang 2 in Mingshui terrace is larger;the denudation thickness of He 2 and Ke 2 in Qianyuan structure zone is much less than that of Dong1 and Dong 401,but the denudation thickness increases in Heiyupao Depression.The character of denudation thickness at the end of K_1n reflected by 10 wells can be described as "large in south,small in north" and "large in east,small in west" in Suihua Depression.
