Research And Application Of Su 53 Block Horizontal Well Optimization

Horizontal well technology is widely used in oil and gas field exploitation,include deployment design to drilling and completion fracturing development technology.According to the characteristics of low permeability reservoir in sulige and phase change quickly, thickness thin, straight wells low yield, carried out the research of horizontal well technology. Mainly from the fine gas reservoir geological characteristics, the deployment of favorable zone optimization, horizontal well deployment and optimization design, Implementation protection technology, carried out careful analysis and research.Through the geological seismic and production data analysis,and optimized the Su 53-4 wellzone for horizontal well deployment area. A 3D geological model is established,the reasonable parameters are determined,are studied by numerical simulation,the parameters were optimized for horizontal wells.The parameters of horizontal wells well reasonable distance,azimuth,length of horizontal section,provides the basic guarantee for the effective development of horizontal wells. In the process of implementation, the application of horizontal well geosteering technology, greatly improving theeffective reservoir horizontal well drilling rate, reduce drilling risks, and laid a good foundation for the follow-up work.Application of horizontal well technology,has obtained the very good development effect in Su 53 block, completed the construction of ten billions capacity by 38 wells in 2 years. Using horizontal well integrated development of low permeability gas reservoir is very successful,horizontal well selected deployment area was very successful,parameters of horizontal well design is also very reasonable.
