侧钻水平井
1.
For the reason that its well-bore has larger curvature,smaller annular space between drilling string and borehole,the inner casing re-entry horizontal well requires not only build-up rate higher but also annular space large as possible,so as to improve drilling fluid's cuttings-carrying capacity.
套管内侧钻水平井由于井眼曲率比较大,钻具与井眼环空间隙较小,要求下部钻具不仅有较高的造斜率,而且环空的间隙尽量大,以提高钻井液的携岩能力,需要在套管内下入弯螺杆钻具组合,由于弯螺杆钻具初始弯曲较大,而套管内径较小,因此,钻柱与井眼的相容性是侧钻水平井钻井的关键技术之一。
