1、There are the bigger differences between slim hole drilling technology and routine borehole drilling technology. Improving of slim hole drilling speed is of an important actual significance.
2、Heavy torque and abrasion on casing are serious problems in drilling in slim hole.
3、There are the bigger differences between slim hole drilling technology and routine borehole drilling technology.
4、The reaming drill bit in slim hole is a key tools of re-drilling in existing well.
5、How to improve the quality of slim hole cementing is a difficult problem of perplexing well drilling.
6、This paper introduced the slim hole drilling designation and operation in shallow gas bearing reservoirs of Chuanxi area.
7、On the base of that, the matching construction of the ocean workover rig for side tracking was discussed. This provided a new way for the slim hole drilling.
8、Cementing of the slim hole is very difficult due to its small hole size and annular clearance, and the conventional cementing technology cannot meet the requirements of field cementing.
9、With the increasing demand of the lateral drilling and slim hole drilling, the coiled tubing (CT) operating technique will play a great role in horizontal well drilling, well workover and completion.
10、The advantages of the slim hole such as reducing cost of drilling, eliminating the risk of the exploration as well as being beneficial to the environment has caught oil field's attention.
11、Therefore, researching the fishing technology of deep and ultra-deep slim hole contains very important meanings to reduce economic losses and speed up the pace of oil production for oil fields.
12、Development of valve device for injection-production integrated technology of heavy oil thermal recovery slim holes
