FIELD APPLICATION OF SIDETRACKING SLIM HOLE PRODUCTION TEST TECHNOLOGY

In the developed oilfields, the sidetracking slim hole technology can cause the low efficient wells or even the dead wells come into life. The economic benefits are obvious and it possesses higher study value and brighter popularizing prospect. Because the diameter of the slim hole is smaller than that of the conventional one, the downhole tools and technologies for completion and production should be improved so as to meet the special requirements of smaller tubing and casing. Taking the production test of the 101. 6mm diameter of sidetracking casing as an example, this paper introduces the development and effective combination of the relevant downhole tools, and the process of running the downhole service tools down to the service section and pulling them safely out of the well. This paper points out that reasonable oil producing mode must be selected to ensure the normal production of the oil wells.
