The technical measure of sand out on top and resin sand at tail is suggested and for those Wells of oil zone developing much better but the physiognomy being complex, horizontal well can be exploited.
建议采取端部脱砂尾追树脂砂工艺措施，对于油层发育较好，但地势复杂的井，可以探索水平井开发。
Specifically, they can successfully negotiate complex well trajectories in horizontal open hole well completions, enabling acquisition of good quality flow profiles in both producers and injectors.
具体来说，爬行器可以用于具有复杂井眼轨迹的、采用裸眼完井的水平井，可以获得生产井和注水井的高质量流动剖面数据。
Due to well deflection and its water content, the flow pattern was complex and variegated in horizontal gas Wells.
由于井身倾斜和含水，水平气井中的流型更加复杂多变。
