摘要
目前针对地层出水条件下气体钻井携水、携岩的研究不多,尚处于探索阶段。地层出水会引起岩屑各种性能发生严重变化,这对环空安全携岩和井壁稳定是一个严峻的考验。通过岩屑受力与岩屑遇水后的团聚性等变化的理论与实验分析,对其基本规律和理论作进一步综合研究,并结合相应计算进行现场实验,计算结果与四川某区块较为吻合。
The study on gas drilling of water bearing formation is less in recent, it is still in probing period. The various performance of cutting begins to generate serious transformation because of the formation water.It is a vital temptation to carrying,cutting safely. The dissertation synthetically analyzes the stress and constipate of cutting in moist condition and analyzes the basic method theory in further under homologous computation system by the theory and laboratory experiment.The result of the system fits the block in Sichuan. The system can offer important reference for the hole cleaning on gas drilling of water bearing formation.
