Water Injection Development Of Oil Field Single Well Injection Allocation Method

This article in analyzes the predecessor to injection water methods in the foundation, had pointed out the predecessor injection water methods the suitable condition and the existence insufficiency, And from "macroscopic matching injection" to develop "microscopic matching injection " this mentality to embark, first take the entire oil field or the sub-area as the research object, from the stage water in storage rate and the stage water drive index definition to embark, uses the optimization analysis method, extracts through the type curves fitting conforms to the oil field to be actual superiorly matches the injection water quantity. After optimization injection water quantity determination, recarefully examines divides coefficient, to affects divides coefficient certain factors to carry on the classification, And uses the grey connection analysis method to affect the factor arrangement, discovers in these factors the major effect factor, Overcame the convention to divide in method artificial to choose the multi-factors to construct divides coefficient but to lack the scientific theory basis the malpractice, Thus scientifically matches the sub-area injection water quantity to be obtained divide to the single well injection water quantity. In the predecessor in the foundation, proposed uses between the water-injection well and the production well dynamic data directly carries on single well injection three new methods. And carries on the contrast analysis by the Xinjiang some oil field actual data, explained this article proposed the new method the note has the certain superiority, the reliability in single injection water quantity in compared to the alternative means. In addition, language established the water-injection well software (IWAS) using Visual C++6.0 , thus enhanced has matched the note working efficiency, Enhances the water-injection development oil field the development level and the management level.
