Production system of zero - offset profile and wavelet profile 零炮检距剖面与小波剖面制作系统
The methods were realized directly inversion of the possion ' s ratio from cdp gather and gas - bearing identify . by applied the late theory of avo technology , after inputting the p wave section and s wave section , the p wave and s wave impedance were obtained by applying simulate anneal inversion and used the log as a constrain condition , eventually , obtain the elastic parameter u and x by p and s impedance . then , the gas - bearing will be identified by u and x . by applying this method , the avo combination inversion of prestack and post were realized 利用上述的反演方法实现了泊松比从道集的直接反演,利用加权叠加技术实现了含油气的识别,并利用当今avo研究的最新成果,以加权叠加技术分离出的p波和s波剖面作为输入,在测井的约束下,采用模拟退火方法分别进行p波和s波波阻抗反演,通过p波和s波波阻抗来求取弹性参数和,再通过和的联合解释来进行含油气的判别,实现了avo的叠前叠后的联合反演。
