The Practice on Accelerating the Horizontal Well of the Xin 123-Ping 80

摘要

The well Xin 123- Ping 80 is a development horizontal well located in XinZhao Oilfield of the NO.9 oil production plant of the PI5 layer. The original design of the well uses single arc section with a full angular rate of change of 8.47°/30 m. The wellbore orbit optimization technology is used in the field construction, and the design is optimized to the vertical well section by the computer software - the first build and hold wellbore - the second build section - the oil detection and landing - the horizontal section seven-section track profile, the full-angle change rate is optimized to 7°~8°/30m, and the 1.25° single-bend screw LWD measurement system is used in conjunction with the construction. The self-orientation of the inclined angle starts to enter the inversion hole assembly, using directional drilling and composite drilling. In a combined manner, a drilling construction is realized, the mechanical drilling speed of the inclined section and the horizontal section is improved, the drilling cycle is shortened, and the comprehensive drilling cost is saved. The successful implementation of this well has provided useful reference for such horizontal well construction, and accumulated valuable experience, which has important guiding significance to shorten the drilling period of horizontal well in Daqing oilfield and popularize the application of horizontal well technology.
