| The characteristics of gas reservoir of Sulige oilfield is very complex, with lateral variation of reservoir, low formation pressure, low reserve abundance, low productivity, complex gas water distribution, poor reservoir property etc.. Su6block of Sulige gas field development is the pilot test area, the evaluation of the two block development effect is of guiding significance for the better development of Sulige gas field.Through geological, gas reservoir engineering, numerical simulation of multidisciplinary, multi professional technology joint research, combined with the gas reservoir dynamic, static analysis of means, tectonic and sedimentary characteristics of Su6block understanding of the progress, mastered the heterogeneity characteristics and reservoir fluid property and distribution of reservoir physical property, Combining with drilling mud logging and well logging interpretation results, established a3D geological model of Su6block, including the lithology model and attribute model, studies the sand body connectivity and distribution, representative of encryption area to carry out the reservoir numerical simulation research, completed the dynamic production history matching, numerical simulation method to complete the evaluation of the current pressure and reasonable well pattern and spacing block, Using the analytical method of gas reservoir engineering, combining production dynamic data, Su6block, evaluation, Su6block development results, including the degree of reserves, production capacity and ultimate recovery factor prediction evaluation, aiming at main problems block development exists, proposed the design and the specific plan the next step adjustment direction, and making the program predicted by numerical simulation method. |
