井网调整后水驱控制程度及油水井接触方式研究

摘要：在油田开发过程中，随着开采的深入以及对油层认识的不断加深，部分区块有必要对原有的井网进行调整以满足当前生产的需要。为了进一步挖掘油田潜能，大庆油田某试验区通过细分重组层系，加密及注采系统调整等方式对老井网进行了重新调整，并根据沉积相带图及射孔等资料，研究了试验区井网调整前后的水驱控制程度及油水井所在砂体之间的接触方式，对比分析了控制程度和接触方式的变化情况，明确了不同调整方式对井网完善程度的贡献值。

Research on Water Flooding Control Degree and Contact Type of Oil and Water Well after the Well Pattern Adjustment

Abstract: During oilfield development process, as the production of the reservoir and the deepening of understanding for oil layer, it is necessary to adjust the original well network to meeting the current production needs in some blocks. In order to further excavate oilfield potential, one test area of daqing oilfield was made a new adjustment by the ways of the subdivision of recombinant oil layer, infill drilling and injection-production system adjustment. According to the data of sedimentary phase diagram and perforation etc, water flooding control degree and the contact type between the sand body of oil wells and water wells are studied before and after the well network adjustment, the changes of control degree and contact way are analyzed, the contribution of different regulating methods to the degree of well pattern complete can be cleared.
