摘　　要：渤中34某区块主要的开发层位为东营组和沙河街组。该区块整体上为夹持在多条断层之间的一个垒块构造,区块内断层比较发育,两组近东西向和北东-南西向断层将该区块切割分为多个断块。在前期开发中,受断层影响,井漏现象频发,并引起多起井下事故,生产时效较低。通过对漏失井情况分析,结合地层特点,提出了防漏、堵漏的多项关键措施,对后续深井开发具有极大指导意义。The main target layers in Bozhong 34 area are Dongying formation and Shahejie formation. The block is a block structure sandwiched between multiple faults as a whole, in the block, the faults are relatively developed. The two groups of near E-W and NE- SW faults divide the block into multiple fault blocks. In the early development, due to the influence of the faults, well leakage occurs fre-quently and causes many downhole accidents, and the production efficiency is low. Through the analysis of the leakage well conditions and the formation characteristics, a number of key measures for the prevention and plugging of well leakage are put forward, which have great guiding significance for the further development of the deep wells.
