综合利用多种地球物理方法预测中层目标含气范围
|
摘要
莺歌海盆地浅层典型已知"亮点型"气藏的地球物理特征已经非常清楚,而且大部分目标都已列入储量计算的范畴,所以勘探潜力不是很大,这就要求我们应该把目光投向中层目标来寻找储量接替.但是若想准确的计算储量,就应该落实目标体的含气范围,但是由于埋深、压力及浅层目标屏蔽的影响,中层目标的地球物理特征我们还不是很清楚,更难较准确的确定含气范围.本文带着这个问题展开研究,第一步通过地震属性分析确定异常体的范围,通过反演确定砂体范围;第二步通过聚类分析确定有利砂体的范围;第三步通过叠后吸收处理判断目标体的含气性;最后,将有利砂体的范围与吸收异常的范围叠合来确定目标体的含气范围.综合应用多种地球物理方法判断目标体的含气性,总结出了一套预测中层目标含气范围的流程及方法,为较准确的落实中层目标含气范围莫定了基础.
We have known the typical "bright spot" gas reservoir characteristics of the Yinggehai basin, and most of the targets have been included in the calculation of reserves. Therefore, exploration potential is not great. This requires that we should set our sights on the intermediate deck goal to seek the reserves to replace. But if we want to calculate the accurate reserves, we should target the the gas-bearing area of objects. However, due to the influence of burying depth, pressure and shallow layer goal shield, we are not very clear of the intermediate deck goal's geophysics characteristic. So it is difficult to determine a more accurate gas-bearing scope. The article has been studying this question. The first stepis to determine the scope of anormal body through the analysis of seismic attributes,and then determine the sand scope through inversion. The second stepis to determine the favorable sand scope through cluster analysis. The third stepis to judge the gas area of goal through the poststack absorbs processing. Finally, we determine the gas bearing scope of the target through scope superposition of thefavorable sand scope and absorption anormaly. we judged the gas bearing scope of the target by the synthesis application of many geophysics methods,summarized a set of process and method to forecast the gas bearing scope of intermediate deck goal, which layed the foundation for the more accurate determination of the the gas bearing scope of intermediate deck goal.
