Research On20Billion Cubic Meters Of Natural Gas Stable Production Technology In The Southern District Of Yulin

With the Southern District of Yulin in2005to complete the construction of capacity, the Southern District of Yulin gas field has been formed well network systems, the main problem facing the field is how stable yield.To this end, the thesis on the basis of existing geological, Southern District of Yulin were divided depositional system to study the planar distribution of sedimentary facies and sand body characteristics of the profile and the plane features; on the pore structure and reservoir types were divided, analyzed the Southern District of Yulin gas reservoirs Hill2characteristics and physical properties of rocks.Full use of exploratory and development wells on the basis of information obtained by combination of gas development dynamic and static data, the use of numerical simulation technology, the establishment of South geological model, re-calculate the Southern District reserves, while taking advantage of the reservoir logging data Relationship between parameters of that study the distribution of reservoir parameters, drawing gas sedimentary facies, microfacies, reservoir properties such as three-dimensional geologic maps, numerical simulation of the Southern District and provide a geological basis for stable production wells.In addition, the thesis also carried out numerical simulation of the Southern District, the prediction of different options, by contrast, preferably well area development program for the rational development of well area provide technical support. Studies suggest that:Well a reasonable rate of3%of gas production, natural stable period of5.8years, through the booster stable, stable period may be extended for2years.
