功图法在油井计量中的应用

Indicator diagram evaluation in oil production is a good and a new method of measurement, it reduces the human consumption in oil calculation station, while it reduces great error in oil calculation by human. Indicator diagram evaluation is mainly determined by gradient method diagram of the inflection point well, and then get the opening and closing point of the van, then it can calculate the effective stroke of the oil wells,finally,through effective stroke it will calculated the production of the well. Through practical application of the measurement technology in jiangsu oil field, this technology achieves good results.
