欢西油田下台阶面积较大,但埋深大于3000m的中深层探明储量仅88×104t,占油田0.4%。通过综合地质研究,对下台阶埋深大于3000m的杜家台油层的构造、储层进行落实,并部署锦323井,取得较好效果,为下台阶中深层的下一步勘探开发提供依据。 Huanxi oilfield has a large area under the step, but the proven reserves in the middle and deep areas with depth greater than 3000m is only 88 × 104t, accounting for 0.4% of the oil field. Through the comprehensive geological study, the structure and reservoir of the Dujiatai oil layer with a depth of more than 3000m in the next step are implemented, and the Jin 323 well is deployed, which achieves good results and provides the basis for further exploration and development in the middle and lower steps.
