Decision-Making for Well Liquid Control Based on A New Oil Production Index

Abstract

In view of the problems of water cut rising too fast and liquid level keeping unreasonable in many oil wells in oilfield production, a comprehensive evaluation study on the reasonable liquid production capacity of oil wells is carried out. Based on the productivity formula, a dimensionless production capacity evaluation model is established by comparing the potential production capacity with the actual production rate. The reasonable liquid production potential is related to the meter oil production index liquid production potential related to water cut, the effective thickness liquid production potential related to sedimentary facies, and the production differential pressure liquid production potential related to liquid level. the comprehensive evaluation system of reasonable liquid volume is formed, and the main factors influencing the liquid production capacity are proposed through orthogonal test analysis, and the reasonable fluid adjustment scheme is determined through comprehensive evaluation. The reasonable liquid production capacity of oil wells in s Oilfield at present is put forward. Good development effect has been achieved after field implementation, which ensures high and stable production of s Oilfield for 5 years. This method has practical guiding significance for evaluating fluid production potential and maintaining high efficiency production.
