制约长庆油田宁定区块长6水平井快速钻进的因素众多,但究其最主要的影响因素文中将做详细探究,对于宁定区块长6水平井来说,同长度水平段生产施工时效已基本相差无几,影响水平井生产时效的主要在直井段与斜井段,文中通过对从直井段至水平段入窗“两趟钻”与“一趟钻”模式的施工时效进行对比分析,及优化钻井液体系、三牙轮钻头的优选等寻求解决影响水平井快速施工的策略,以为长庆油田宁定区块长6水平井的安全、优质、高效施工提供一定的参考。
There are many factors restricting the rapid drilling of the horizontal well in the Changding Oilfield, Ningding Block. However, the most important influencing factors are discussed in detail in the paper. For the 6 horizontal wells in the Ningding block, Construction time lag has been basically the same, the impact of horizontal well production aging mainly in the straight section and inclined section, the article from the straight section to the horizontal section of the window into the “two trips” and “one trip” mode The comparative analysis of the aging of construction and the optimization of drilling fluid system and the optimization of tri-cone bit etc. to solve the problems that affect the rapid construction of horizontal well in order to provide certainty for the construction of safety, high-quality and high-efficiency 6-long horizontal well in Changning Oilfield The reference.
