摘要
目前YB地区总体钻井事故频发,钻井效率较低,钻井周期较长。欠平衡钻井技术是降低钻井成本,提高钻井效率和缩短钻井周期的重要手段,为此,研究了YB地区陆相气层的分布规律,明确了含气井段及含气有利区域,为YB地区陆相气层开采及实施欠平衡钻井提供了技术支持。
Recently,accidents have frequently occurred during drilling YB area,accompanied by lower efficiency and longer cycle.In the future,more and more development and evaluation wells need to be deployed resulting in heavy drilling task.In addition,underbalanced drilling is an important technology to reduce cost,increase efficiency and shorten cycle.Therefore,in order to provide technical supports for recovering gas and implementing underbalanced drilling in YB area,it's necessary to master the distribution law of continental gas reservoir,and define the gas-bearing and favorable area.
