含局部非均质区碳酸盐岩油藏产量变化规律
PRODUCTION CHANGE LAWS FOR THE CARBONATE OIL RESERVOIR WITH PARTIAL HETEROGENEITY
摘要
Abstract
Boundary element method has been widely applied in the seepage flow of partially heterogeneous oil res ervoir, but it is only limited in pressure prediction, the unsteady production prediction has not ever been reported. Based on the above method, the calculating method for the unsteady production is first obtained, and the influences of the partially heterogeneous region on the production decline curve is studied. The researches show that when the mobility ratio is smaller than 1 in the above region, the oil production is higher than that of the other region (the mobility ratio is equal to 1) ; when the ratio is above 1 , the production is less than the other. When the ratio is be low 1, the bigger radius of partially heterogeneous region is (that is the bigger the partially heterogeneous region area is) , the higher the production is, the closer the region from wells, the higher the production is.关键词
