苏北盆地昌荣区块地震采集实验研究——基于双井微测井的表层调查
|
摘要
该文是在苏北盆地昌荣区块实施三维地震采集之前,对影响采集资料的一些因素所做试验的分析。选择工区内有代表性的两个试验点,利用双井微测井方法进行表层结构调查分析,结果表明工作区近地表为两层结构,确定了虚反射界面的深度;干扰波的调查分析为检波器的组合方式提供了依据;利用双井微测井的分析结果,对比不同井深、药量和组合井的试验,给出了适合工作区的激发参数,为野外生产提供了指导。
Seismic exploration plays an important role in surveying oil and gas resources,quality of field seismic acquisition data affected directly on exploratory process.In order to improve the quality of seismic record,the analysis of basic data and the trial of the acquisition factors of systematic shooting and receiving are indispensable before carrying out produce.In this paper,influential factors on seismic acquisition data was analyzed by means of test before carrying out 3D seismic acquisition of Changrong block in Subei Basin.Two typical experimental locations in the block were selected,where surface structure was surveyed through adopting methods of double-hole micro-logging.The result showed the surface of this area contains two layers,at the same time,the depth of ghosting interface had been determined.According to analysis of interference wave,mode of geophone array had been determined too.In addition to,referring to analytic result of double-hole micro-logging,the results of varied well depth and content of dynamite and member of combination well were compared,and excitation parameters suited to the characteristics of this area were got,and the guide for next field production was provided.
