Development and application of on-line calibration device for water injection flowmeter

Abstract

In the process of oilfield waterflood development, the rate of water injection is an important embodiment of water injection management level, which is an important parameter that not only reflects the formation capacity, but also reflects the production capacity of water injection equipment. Because of the influence of injection water quality, production environment, management level and other factors, the water injection flowmeter needs to be calibrated regularly to ensure the accuracy of measurement in the actual water injection process. In Huabei Oilfield, the flowmeters used in the production are removable for calibration, which has problems such as the difficulties when dismantling and mounting the flowmeters for calibration outside, easily being damaged in transit and low calibration efficiency. In order to solve above problems, a set of on-line calibration skid-mounted device for water injection flowmeter is developed, which realizes on-line calibration for water injection flowmeter and meets the actual demands of water injection flowmeter calibration in oil field.

Research and Application of the Fourth Generation Stratified Water Injection Technology in Daqing Oilfield

“…(1) The contradiction between the increasing workload of water injection well testing and adjustment and the limited testing team is increasingly prominent. (2) The point test data of conventional separate injection process is difficult to meet the (3) The conventional separate injection process cannot support the digital transformation and intelligent development of the oilfield [9][10][11][12][13][14][15][16] . In order to solve the above problems, Daqing Oilfield has studied the cable-controlled layered water injection technology and carried out demonstration application.…”
