下二门油田薄层稠油藏注蒸汽开采方式探讨

Feasibility study of Steam injection in Xiaermen Oilfield heavy oil reservoirs

本文针对下二门油田浅北区块H 2Ⅰ2、3小层为薄层稠油油藏,常规试采及出砂冷采产量低的情况,根据其储层物性、原油性质、油层厚度及注蒸汽吞吐试验结果等油藏地质特征,开展了开发方式对策研究,提出H 2Ⅰ3小层宜采用注蒸汽开发,并根据已开发油田的生产情况及数模结果,对注气参数的确定进行了探讨。

This article in view of Xiaermen oil fields Qianbei block H2 I 2, 3 subzones for the thin layer heavy oil reservoirs the convention tries to pick and the granulated substance coldly picks the output low situation, according to its reservoir nature, the crude oil nature, the core interval and oil deposit geological feature and so on note cyclic steam injection test result, has carried out the development way countermeasure research, proposed the H2 I 3 subzones suitably use the note steam development, and according to has developed the oil field the production situation and the digital-analog result, has carried on the discussion to the gas injection parameter determination.
