油田采油中,复杂断块油田的油气储藏分部的情况复杂主要原因在于断层将油层与储层油气分部的情况复杂化,导致油藏分布状况的准确勘具有较大难度,故而在判断油田内油气的分布状况,必须首先对油田中断层分布做精准判断,并更具断层的特征为断层构建格架,从而精准的判断出油层和储层的实际分部状况。对复杂断块油田在二次开发阶段的油藏情况进行精细描述有利于针对性的解决二次采油中存在的采油问题,对提高采油效率和稳定采油率具有前提性的保障作用。本文对复杂断块油田的二次开发阶段油藏的精细描述做简要分析。
The main reason that oil and gas reservoirs in complex fault block fields are complex in oilfield production is that the faults complicate the reservoir and oil and gas divisions and make it difficult to accurately survey the distribution of reservoirs. Within the oil and gas distribution, we must first make accurate judgments on the fault distribution in the oilfield and make the fault more characteristic of the fault-building framework, so as to accurately determine the actual subdivision of the reservoir and reservoir. The detailed description of the reservoirs in the secondary development stage of complex fault block oil fields is helpful to solve the problem of oil recovery existing in the secondary oil recovery in a targeted manner and has the precondition guarantee for improving the oil recovery efficiency and the stable oil recovery rate. This paper gives a brief analysis of the detailed description of reservoirs in the secondary development stage of complex fault block oilfields.
