浅层水平井具有埋藏浅,地层欠压实,胶结疏松的特点,为了满足热采的要求,油层套管要求尺寸较大,进而要求造斜段井眼较大,实现浅地层大尺寸井眼高造斜率非常困难,通过对造斜率理论的研究,在地层自身造斜率一定的前提下,通过研制高造斜率导向工具能够提高浅层水平井造斜段的造斜率,达到井身设计要求,并在现场应用效果良好。
Shallow horizontal wells have the characteristics of shallow burial, under-compaction and loose cementing. In order to meet the requirement of thermal recovery, the size of casing requires a large size, which in turn requires the larger borehole to be formed and the large-size borehole in shallow formation Through the research on the theory of SLR, under the premise of the slope being made by the strata itself, it is possible to improve the slope-making rate of the slant section in the shallow horizontal well through the development of the SLR tool to meet the design requirements of the wellbore. And the application of good results in the field.
