The Yanggao Temple Field Maokou Group Of Gas Reservoir Resources Potential And Develop Countermeasures

The Maokouzu reservoir in Yang'gaosi district is a typical low-pressure reservoir, which has 47-year production period and maintains production pressure between 1-2 MPa at present. It has 51 completed wells and 31 gas wells by the end of 2009, Jialinjiangzu reservoir has 15 gas wells, the same as Maokouzu reservoir, and Changxingzu reservoir just got 1 gas well. The whole reservoir has cumulatively output 49.38×108m3 gas and 141.52×104m3 water, including 36.79×108m3 gas and 141.23×104m3 water from Maokouzu reservoir, which has got 45.52×108m3 original gas reserves in place and remaining 8.73×108m3 unexploited (The Yang 7 district, Yang 47 well and Yang 49 well got 6.18×108m3, reach 70.79% of the whole unexploited gas reserves in place).This paper has done dynamic characteristics research to distinguish the reservoir type; analyses the pressure and temperature of reservoir; analyses the distribution and relationship of the gas-water, reexamine the gas reserves in place and recoverable reserves; forecast the well or reservoir productivity etc. Finally, this paper will get the Maokouzu reservoir potentiality, and make the development countermeasures, in order to enhance the Maokouzu reservoir recovery almightily.
