基于注聚区探讨高压水井分层测试工艺现状

Discussion on Hierarchical Test Technology of High Pressure Wells Based on Injection Zone

随着我国经济的快速发展,对于石油的需求量有增无减。据统计,2018年我国石油总消耗量为7亿多吨,对外依赖程度大于70%。这对我国国内的石油开采提出了更高的要求。由于国内油田的油藏大多数都为非均质油藏,因此常采用分层注水工艺进行开采。开采质量很大程度上取决于高压水井的分层测试工作,这关系到后期油井开采的方案计划甚至打捞上来的原油的质量,如果前期没有做好高压水井的分层测试工作,贸然开采石油,可能会引起安全事故。本文基于油田注聚区展开讨论,对在高压水井分层测试的过程中可能会出现的问题进行了总结,同时提出了解决办法。

With the rapid development of China's economy,the demand for oil has increased. According to statistics,in 2018,the total consumption of China's oil is more than 7 tons,and the degree of external dependence is more than 70%. This puts higher demands on China's domestic oil exploitation. Since most of the oilfields in domestic oilfields are heterogeneous reservoirs, layered water injection processes are often used for mining. The quality of mining depends largely on the stratification test of high?pressure wells. This is related to the plan of oil well exploitation in the later stage and even the quality of crude oil that has been salvaged. If the stratification test of high-pressure wells is not done in the early stage,it is rash. Mining oil may cause a safety accident. Based on the discussion of oilfield injection zone,this paper summarizes the problems that may occur in the process of stratified testing of high pressure water wells,and proposes solutions.
