摘　　要：MVR10 7井目的层是纯砂岩薄气层。为确保水平段在产层穿行 ,卡准目的层位置及厚度 ,该井分 2步钻成 ,首先根据邻井资料 ,设计并钻井斜角为 56.95°领眼 ,穿过目的层 ;然后根据领眼钻井资料 ,设计水平段的轨迹进行侧钻。施工时 4次调整水平段设计 ,适时变换参数 ,合理组合钻具 ,成功地完成了该水平井的钻井作业。详细介绍了MVR10 7井的工程设计、井眼轨迹控制、典型钻具组合以及水平井施工相关配套的钻头选型、油基钻井液使用、钻机设备配套等技术 ,为同类油藏的钻井提供了经验。The target zone of MVR107 well is a thin pure sandstone gas r eservoir To ensure to penetrate the target reservoir in horizontal section, a pilot hol e with a deviation angle of 56.95 degree was firstly drilled to calibrate the de pth and thickness of the target, then plugged back. After that, programmed the t rajectory and sidetracked from the pilot hole. During the later operation, the p rogram was changed 4 times. The first horizontal well in this area was completed successfully with proper drilling parameters and BHA. This article presented th e engineering program, trajectory control and typical BHA in details and related techniques, including bit selections, oil-based mud maintenances and rig equipm ents etc.
