Comprehensive Adjustment Of Steam Flooding In The Northern Experimental Area Of ??J230 Well Area

The heavy oil resources of our country is quite rich,with the constant improvement of the technology of heavy oil exploitation,some special reservoir is more and more cause the attention of oil workers.The current technological and economic one of the most successful way is to steam stimulation and steam drive.In this paper,the author studies on J230 the wellblock Qi ancient group oil reservoir,because of its crude oil viscosity,temperature and original formation pressure is low,small natural drive energy,at present the test area in throughput since two rounds of steam drive development.In order to verify the Xinjiang oilfield J230 wellblock Qi ancient group reservoir feasibility of steam drive,turn on encryption steam flooding area sedimentary and reservoir heterogeneity,a comprehensive description found in northern encryption on steam flooding area whole reservoir development is good,but controlled by the sedimentary environment,and the plane residual oil distribution,oil/water relationship is relatively complex,the injection-production parameters cannot effectively ensure uniform steam drive overall propulsion,urgently needs to adjust steam injection production.As a result of steam drive,the steam sweep rule of reservoir physical properties,sedimentary characteristics.The encrypted area of steam flooding development effect analysis and evaluation,find out the main contradiction existing in the steam flooding process.According to the present situation of steam flooding,the oil reservoir in northern steam injection parameters for the reasonable optimization;For different steam flooding contradictions of steam channeling well group and did not work well group put forward the concrete Suggestions on governance,eventually achieve the goal of improve the effect of steam flooding development.
