低渗透油田油藏采油技术研究

Research on Oil Recovery Technology of Low Permeability Oilfield Reservoir

随着社会经济的发展和进步,各行各业对油气能源的需求量也不断上升。在石油行业的迅猛发展中,石油勘测技术也在日益更新。由于我国石油资源非常丰富且发展迅猛,有些勘采水平已经达到世界顶尖级水平。但是我国在石油开采的过程中也存在很多难题,如油田分布得较分散,地理位置也较复杂,不利于开采工作的进行。油田井下压裂技术就属于这类,井下压裂技术容易受地势的影响,其发展水平与其他发达国家技术相比还存在较大的差距,需要不断提高技术水平。主要研究了低渗透油田开采技术发展的现状,并提出相应的问题和解决对策。

With the development and progress of the social economy,the demand for oil and gas energy in various industries is also rising.In the rapid development of the petroleum industry,petroleum survey technology is also being updated.Due to the abundant and rapid development of China’s petroleum resources,some exploration and mining levels have reached the world’s top level.However,there are still many problems in the process of oil exploitation in China.For example,the distribution of oil fields is more dispersed and the geographical location is more complicated,which is not conducive to the mining work.Downhole fracturing technology in oilfields belongs to this type of typical.The downhole fracturing technology is easily affected by the terrain.The development level of the oilfield is still far from the technology of other developed countries,and it is necessary to continuously improve the technical level.This paper mainly describes the status quo of low-permeability oilfield mining technology development,and proposes corresponding problems and solutions.
