摘要
兰尕背斜带处于塔河油田南部,具有发育非背斜圈闭的条件,勘探程度较低,依赖于初始模型的常规反演方法难以获得精确的反演结果。而约束稀疏脉冲反演不依赖模型,其反演的精度取决于原始数据特征。为此,在兰尕地区利用约束稀疏脉冲反演技术进行了储层预测。首先简单介绍了约束稀疏脉冲反演技术的基本原理及其实现方法,然后对砂体发育带进行了预测,其反演结果与井的钻探结果基本吻合。
The anticline belt of Langa locates in the south Tahe Oilfield where bears condition of developing non-anticline straps, but its exploration level is low. It is difficult to get enough accurate inversion result with traditional inversion method due to its dependency on initial model. The constrained sparse spike inversion (CSSI) is used to predict the reservoir in Langa Area since it does not rely on the model, its accuracy merely depends on the characters of original data. Firstly introduced are fundamental principle and realization of the CSSI then carried out are forecasts of development of sand bodies by the method. The inversion results are basically consistent with the drilling outcomes.
