Research On Application Of Dynamic Monitoring Technology In Exploration And Development Of Xinggu Qianshan

In order to further improve the understanding of the Qianshan reservoir,to carry out monitoring work on XingGu Qianshan reservoir,by comparing the dynamic monitoring data,get the pressure changes of Qianshan reservoir,to determine the reasonable working system,resservoir type,determine the formation conditions of connectivity and absorption ability,provide the basis for the adjustment scheme and development scheme of the block.The research contents of this paper are: one is to carry out systematic testing,by monitoring the pressure and flow pressure to track of reservoir pressure;Two is to carry out the interference test to get well interference conditions;Three is to carry out the pressure recovery test to calculate the reservoir pore characteristic parameters;Four is to carry out the injection test work,through the analysis and research of water injection instructions curve to get water absorption capacity of the reservoir.Through the reservoir pressure curve analysis of these change to the track pressure change,in a timely and accurate grasp of the dynamic change of reservoir pressure and clear the relationship pressure and production capacity,combined with the testing system,reasonable the adjustment of flowing well production system,ensure the reasonable production flowing well,maintaining a gusher ability.Based on the analysis of interference data between wells,it is proved that the connectivity between wells and sections in the different sections of the XingGu Qianshan,Through the comparative analysis of the data obtained from the pressure recovery test between the two years before and after the test,to get the block permeability is poor,no pollution of the well,the completion of good results.Through the analysis of the starting pressure,water absorption index and other data,we can get the implementation of the reservoir’s water absorption capacity and characteristics.
