Abstract
At present, adaptive inflow control (AICD) water-controlled completion technology is mainly applied to reservoir water control. In view of the gas reservoir AICD water control completion technology research is still blank, this paper carried out a suitable for gas reservoir water control water control mechanism of the new type runner AICD and flow characteristics analysis, X oilfield bottom water reservoir is established new port type AICD water control completion. The structure parameter combination of the new AICD was analyzed and optimized by orthogonal test, and the water control effect of the new AICD water control completion was analyzed. The results show that compared with conventional perforation completions, the new AICD controlled water completions cause little bottom hole pressure loss and have little effect on condensate production. New type runner AICD completion can prolong the bottom water reservoir water control in low yielding water gas recovery period of about 365 days, predict 20 years of accumulated water rate reduced about 27%, water saturation near wellbore area is generally lower, has good effect of water control. The new flow channel type AICD controlled water completion can be applied to the development of bottom water gas reservoirs to control water and stabilize gas.
Highlights
Horizontal wells have been widely used in oil and gas field development
In heterogeneous reservoirs, the flow profile of horizontal wells is greatly affected by reservoir heterogeneity, and early water intrusion occurs at the heel of the well or in the high permeability area, reducing the recovery factor [1,2]
For bottom water gas reservoirs developed by horizontal Wells, reasonable and effective water control completion technology is the key to efficient development of bottom water gas reservoirs [3]
Summary
Horizontal wells have been widely used in oil and gas field development. Compared with vertical wells, horizontal wells can achieve greater reservoir contact area and lower pressure drop. For bottom water gas reservoirs developed by horizontal Wells, reasonable and effective water control completion technology is the key to efficient development of bottom water gas reservoirs [3]. The AICD that has achieved commercial application mainly includes flow channel type and floating disc type [4]. It has achieved good water control effect in bottom water reservoir application [5,6], and is a completion technology worthy of research and promotion in bottom water and gas reservoir. At present, AICD water-controlled completion technology is mainly applied to reservoir water control, and the research on AICD water-controlled completion technology for gas reservoirs [7,8] is still not perfect. The bottom water condensate gas reservoir of X oilfield was taken as the research target, and the dynamic simulation study of the new AICD water controlled completion technology in bottom water gas reservoir was carried out, and the parameters of the new AICD water controlled completion were optimized
