摘要
顺北区块普遍存在二叠系易漏易垮、志留系易掉块垮塌、桑塔木组火成岩侵入体易垮易漏等问题,长裸眼防塌防漏矛盾突出,安全密度窗口窄严重制约着钻井施工进度。
The Permian is easy to collapse in the north of the block, and the Silurian fault is collapsing, and the igneous rock intrusion in the Santa group is easy to collapse and so on.The contradiction between the anti-Narrowly restricting the progress of drilling construction.
