Jingbian-yanshuiguang Pipeline Takahashi And Study Of The Ancient Law Of Gas Well Production In A Comprehensive Way

Jingbian-yanshuiguang pipeline GaoQiao District and southern district in put into scale development in 2011,2011 to build capacity of 8.26×108m3/a, build capacity of 12.22 2012×2012 m3/a. Test analysis shows that jiangsu and old gas well production capacity difference is big, high bridge formation coefficient range is wide, indicates that the reservoir heterogeneity is strong. Jingbian-yanshuiguang pipeline takahashi and southern district and put into production in a short time, is at the early stage of development, gas well production rules have yet to be felt, though about the document of gas well and gas reservoir dynamic analysis is more, but for the complex reservoir conditions and mining conditions of comprehensive system evaluation method study is less, not form a series of dynamic analysis technique; The area under the ancient gas well affected by reservoir heterogeneity, the gas well capacity of gas and water production characteristics difference is big, the production management is difficult.Gas well production of gas well production dynamic display, lower palaeozoic era high single well production, gas capability is strong, but there is large difference of capacity, moisture than the big, big pressure drop quickly, the decline rate, etc., to scientific and effective development and utilization of the ancient gas reservoir reasonable gas reservoir development potential evaluation of lower palaeozoic era, under the correct understanding of the ancient gas well production characteristics, requires full application testing, test and production of gas well production performance data, analysis of the gas well production rule, established under the old gas well classification standard, the different types of production from the well and stable yield ability, thus optimizing the ancient gas well production system, determine reasonable allocation of gas well, may be to improve the effect of gas reservoir in the overall development in the region to provide guidance. The project is mainly from the ancient gas well with dynamic and static data, the ancient gas well testing, pre-production, production performance data is given priority to, for a comprehensive study on the regular pattern of production in gas well productivity, different types of gas well production under the ancient law studies, with reasonable allocation of gas Wells in the study, evaluation, gas well dynamic reserves and recoverable reserves of gas well the law of diminishing or and decline rateevaluation, index of field development evaluation, the results obtained, the next step for gas field development and management to provide scientific and reasonable basis.Set up an experience points capacity calculation formula of gas Wells and gas Wells takahashi in the south of jiangsu, double calculation gas field in the south of jiangsu 61 ancient average open flow potential under 23.24×104m3/d(jingbian-yanshuiguang pipeline ancient average open flow potential under 25.62×104m3/d),9producing horizon horse five5,56 Wells an average of 79.10×104m3/d open-flow capacity, and the rest of the 53 average well open-flow capacity 13.57×104m3/d. Takahashi field average 35 Wells open-flow capacity 5.64×104 m3 /d.
