Study on Injection-Production Adjustment Technology in Sanduo Oilfield
Institute of Geology, No.9 Oil Production Plant of Daqing Oilfield Co., Ltd., Daqing, Heilongjiang, 163000 China
On the basis of understanding the geological characteristics of low permeability oil fields with scattered sand bodies, this paper studies the water injection policy, response characteristics and the oil fields entering the middle water cut stage since the production. Affected by the scattered underground sand bodies, it is exposed to the influence of low water flooding control degree and less water flooding direction. After water breakthrough, it is difficult to adjust the water well scheme and the formation pressure level is low. In order to alleviate the above contradictions, oil wells are converted to injection, water drive control degree is improved, and formation energy is increased. In order to improve the control degree of sand bodies, several schemes are compared to find out the transfer injection mode suitable for oil fields with scattered sand bodies, increase the proportion of multiple connections and improve the oil recovery ratio.
Key words: Sand body distribution / Affected characteristics / Middle and late water cut stage / Development contradiction / Transfer note
