川东黄龙场构造上二叠统长兴组生物礁特征与潜伏礁预测
|
摘要
通过黄龙场4口上二叠统长兴组钻井岩心剖面和其他井相关资料的详细研究,证实黄龙1井、4井有生物礁, 黄龙3井、5井无生物礁;生物礁由海绵障积岩组成,属于台地边缘礁。针对礁与非礁地层物性差异小,非均质性强, 多解性问题突出的特点,运用地质、测井和地震相结合的预测方法,确定了黄龙1井区的生物礁气藏发育边界,并发现了黄龙5井西侧生物礁气藏,为川东生物礁预测提供了一种实用的方法。
Study of four well cores and relevant data of other wells obtained from the Upper Permian Changxing Formation in the Huanglongchang structure has demonstrated that there are organic reefs in cores from the Huanglong No. 1 well and Huanglong No. 4 well but no reefs in cores from the Huanglong No. 3 well and Huanglong No. 5 well. The reefs consist of sponge bafflestones, which belong to carbonate platform margin reefs. Due to little difference in physical properties of reef and non-reef strata, strong heterogeneity in reefs and outstanding multiple solutions to the prediction problem, the authors used the prediction method of combining geological, logging and seismic approaches to determine the boundary of the organic reef gas reservoir in the Huanglong No.l well area and found an organic reef gas reservoir on the western side of the Huanglong No. 5 well. Thus a practical method for predicting reefs is provided.
