- Abstract
The microgravity monitoring technology is to convert the superposition field into the difference field, and obtain the more real information of the change field. The result has nothing to do with the single well point. It is the objective description of the overall density and fluid change of the oil and gas reservoir, and it is the overall monitoring of the oil and gas reservoir. It creates conditions for overcoming the multi-solution of interpretation, and its monitoring results are closer to the truth. Therefore, this paper proposes to use the microgravity monitoring results to describe the distribution of residual gas, and to evaluate the development well location and the development potential of residual gas. Firstly, the characteristics of gas bearing formation on microgravity abnormal section are analyzed. Secondly, the development well location evaluation and residual gas potential evaluation model are established. Finally, the microgravity monitoring technology is applied to the Su14 infilled well area, the remaining gas plane distribution is described, the development well location and the remaining gas development potential of the Su14 infilled well area are evaluated, and the next step of the remaining gas development comprehensive adjustment plan and countermeasures for potential tapping are proposed. The adjustment method carried out index prediction, and used the numerical simulation results of the Su14 infilled well area and the production performance analysis results of the development wells to verify the accuracy of the microgravity monitoring residual gas distribution results and the evaluation model.
