Study On The Method Of Menitoring And Volume Calculation For Water Invading In YD2Gasfield，talimu Basin

Water invading often happens in the development of condensate gas reservoirs. Italways greatly impacts the performance of reservoirs, decrease the production of gaswells. Further, this damage the income of gas reservoirs. So, it is very important tolearn the identification as well as calculation of water invading dynamics. Theanalysis can also be very necessary for adjustment of work system, prolong the periodof no water production and decrease the payment of development, thus, contributesthe overall economic results.This research mainly make the study on water invading identification and waterinvading volume calculation for YD2reservoir in Talimu Basin. This research can beconcluded as follows:(1) Firstly, the geology characteristics and development process had been viewedand analysized. The structural characteristics, the porosity and permeability as well asthe fluid characteristics were all learned through quantification and practical data.(2) The production of YD2has been calculated by some related methods, and thedistribution in the reservoirs had also learned through all YD2. This work paly a keyrole or afterward analysis.(3) The dynamics of waterflooded gas wells in YD2had been quantativelylearned. Several sets of method for water production in gas wells had been concludedcombing the conventional reservoir Engineering methods(4) The type scheme of flowing pressure units-less for YD2had been set up. Thisscheme can be a goof tool for trend analysis, remarks on the gas well productionpotential for single wells in the given reservoir as well as the accumulate productionvolume after water flooding.(5) The invading volume as well as some parameters had been determined bygeology reserves and Optimization methods. These evaluates the activity of waterenergy. Also, these methods had also compared.
