Design and Operation of Two Stepped Horizontal Wells |
| |
| Abstract: | This paper presents the design and operation of two stepped horizontal wells——Lin 2 Ping 1 well and Tian 18 Ping 1 well,Shengli Oilfield;puts forward stepped horizOntal well profile design model and well trajectory control techniques;sums up and analyses the suitable condition,operation method,bottomhole assembly features,drilling fluid selection and technical ecnomics evalution for stepped horizontal wells.A successful way has been probed into for future applications of horizental wells in developing the reserviors in complex tracts in China. |
