Study on the influence of different key parameters on EOR in LB block

Abstract: The high temperature reservoir is in the high water cut stage after long-term development, and the inefficiency or invalid circulation caused by injected water is aggravated. With a long development history, the well pattern has been adjusted many times, and the remaining oil distribution is highly dispersed. Based on the high-temperature reservoir conditions of the target block, the influence analysis of different key parameters on EOR effect of LB- block was carried out. The gas flooding and chemical floodin… Show more

“…The complex fault block reservoirs located in east-central China are predominantly terrestrial sedimentary reservoirs with numerous oil layers and severe non-uniformity. To improve the recovery of residual oil without deploying new wells to densify the well network, most of the old oil fields have been studying the method of injection and extraction coupling [1,2]. Therefore, it is of great practical significance to clarify the issues of layer heterogeneity, within-layer heterogeneity and plane heterogeneity, and to explore the flow fixation problems in the direction of the original fluid flow for the development and adjustment of old oil fields.…”
