Research On The Production Rule And Effect Evaluation Of The Horizontal Well Of Su 14 Block

At present, Sulige gas field horizontal well development continues to expand the scale, the subsequent development of horizontal well facing production rules is not clear, need to carry out horizontal well production capacity approved, the exploitation of the formulation of the feature evaluation and management measures, track and analyze the dynamic characteristics of the production. Based on the results of previous studies, summarizes the study area geological characteristics of gas reservoirs; through Su 14 horizontal wells development zone has been carried out of horizontal well production data analysis, comprehensive application of gas reservoir engineering, describe the percolation theory and well test interpretation, dynamic, numerical simulation of multiple, combined with measured formation pressure and well testing interpretation, implementation of the formation pressure and gas well control reserves, determine the productivity of horizontal wells, analysis of the main controlling factors of affect the productivity of horizontal wells; by single well decline analysis, master gas well production decline rule. Based on dynamic and static data. the production rule and the law of water production in different production conditions are analyzed, and the management measures of different production stages are put forward. Based on the above research, this research puts forward the reasonable mining system and suggestion to guide the production and provide technical support for the reasonable and efficient development of gas reservoirs in order to realize the economic development of the gas field.
