【摘要】：三维水平井技术有利于解决油气藏地面条件限制,提高井网部署质量,提高油气藏综合开发效率,具有明显的优势。通过对4种常见三维轨道计算模型进行分析,优选出斜面圆弧法作为三维水平井计算模型,并对三维水平井轨道形式进行优化,提出六段制水平井设计方法,以克服油藏垂深和造斜率2个不确定因素。该设计方法在JH17P25井进行了应用,完钻井深2 235 m,偏移距425 m,扭方位井段347 m,扭方位49.30°,现场施工顺利,轨迹符合率高,克服了油藏垂深的不确定性,取得了较好的应用效果,为后续三维水平井设计和施工提供了经验。
[Abstract]:Three-dimensional horizontal well technology is beneficial to solve the limitation of surface conditions of oil and gas reservoirs, improve the quality of well pattern deployment and improve the comprehensive development efficiency of oil and gas reservoirs, which has obvious advantages.Through the analysis of four common 3D track calculation models, the inclined arc method is selected as the 3D horizontal well calculation model, and the track form of the 3D horizontal well is optimized, and the design method of the six-stage horizontal well is put forward.In order to overcome the reservoir vertical depth and slope two uncertain factors.The design method has been applied in JH17P25 well. The drilling depth is 2 235 m, offset is 425 m, torsional azimuth well section is 347 m, torsional azimuth is 49.30 掳, field operation is smooth, track coincidence rate is high, the uncertainty of reservoir vertical depth is overcome, and good application effect is obtained.It provides experience for the design and construction of three-dimensional horizontal wells.
