Zhaike Area Water Injection Dynamic Analysis

Xiqu oil recovery factory of Yanchang oilfield production had jurisdiction over oilfield, low permeability oil field, belong to put into production in mostly when the fracturing, because of the reservoir heterogeneity and mining sediment group, in different water injection appeared in the process of all kinds of questions, reflected in the layer, layer in between, plane injection-production contradiction; Injection-production adjustment lack of full basis.In this paper, the Zhai13water injection station of Xiqu oil recovery factory for research scope, with the object resevroir of Chang2(2nd Part of Yanchang Formation), development further careful research, in logging data, on the basis of the standard layer under control in" cycle comparison, classification control" contrast method, the strata of fine division and correlation. And regional data analysis and studies the sedimentary microfacies in the reservoir type and distribution of oil and water Wells, through the production process monitoring and dynamic analysis, this area in reservoir numerical simulation and the remaining oil distribution, and put forward the next step adjustment measures for tapping, sort out a set of suitable injection-production this development train of thought, improve water injection effect, and the water injection recovery has five years, more than60000tons of crude oil production, stage recovery degree of a2.6%increase understanding, finally solve the reservoir layer and layer between the plane, in contradictions, realizing the water injection development benefits maximization.
