Horizontal Well Bottom-Hole Pressure Drop Steam Flooding Numerical Calculation

SUN Qiji, WANG Xu

Abstract


In the steam flooding process, when steam injection rate is high, wellhead and bottom hole string pressure substantially increased, oil displacement effect is affected. The numerical simulation method was used to study the process of horizontal steam flooding steam injection rate, steam hold on horizontal liquid rate and the number of holes, pore size to wellhead and bottom-hole pressure and the influence of tubing string. The calculation results show that: the steam injection amount was larger, the more pressure on the bottom of the well and string; the pipe diameter holes on the quantity increased, and the bottom of the well and the smaller string pressure. Injecting steam with more liquid rate the higher pressure were on the bottom of the well and string. Only properly reduce steam injection rate and the liquid rate, holes quantity and holes were reduced .the inner diameter tubing stress and bottom holes dramatically risen could be effectively reduced.
