川西南部地区上三叠统天然气勘探技术研究
|
摘要
在归纳、总结、深化研究川西南部地区上三叠统数十年油气勘探经验、技术和方法的基础上,形成了适用于该区天然气勘探的技术系列,包括气藏地质综合评价技术、构造圈闭识别技术,储层测井评价技术、地震储层预测技术、储层增产改造技术、地质随钻跟踪技术等,在莲花山—张家坪、灌口地区应用取得良好效果,为新区新层的发现和提高气井成功率提供了技术保障。这些技术系列的形成,与勘探战略、勘探思路的创新密不可分。
During the past several decades,the Upper Triassic oil and gas in the southwestern Sichuan Basin have been studied.And some exploration technologies form,including geological comprehensive evaluation,structural-trap identification,well-logging evaluation,seismic evaluation,stimulation and reforming,and tracing with drilling.So far,their application to Lianhuashan-Zhangjiaping and Guankou areas obtained better results and they may provide a technical support for discovering both new blocks and reservoirs and increasing a success ratio to explore gas wells.
