近年来,辽河曙光油田较多井部署在老区块,地下老井网对钻井施工影响较大,防碰形势较为突出。防碰绕障处理不当极易碰漏老井套管,造成井下事故。本文以杜84-兴H3004CH井为例,就施工中如何通过调整钻进方式来控制井眼轨迹,从而实现防碰绕障做简要综述,对该区块后续水平井防碰施工有借鉴意义。 In recent years, Liaohe Shuguang Oilfield more wells deployed in the old block, the underground well pattern has a greater impact on drilling, anti-collision situation is more prominent. Anti-collision around the fault easily handle the old casing leaks, resulting in underground accidents. In this paper, taking Du 84-Hing H3004CH well as an example, how to control the wellbore trajectory by adjusting the drilling mode in order to achieve a brief overview of the anti-collision faults is of great significance to the subsequent anti-collision construction of horizontal wells in this block.
