Study On Oil Producting And Water Flooding Technique Of Slim Hole In Jilin Oil Field

After the long period of development in Jilin oil field, many of the new found blocks are low permeability reservoir, where daily capacity per well is only a few tons, and the conventional development is usually uneconomical for them. According to foreign references and preliminary work of domestic oil fields, the slim hole recovering techniche could reduce cost to a certain degree, so as to achieve the purpose of economic development.The slim hole technique for oil production could be implemented without problem of technology or equipment for drilling industry, but there are still some technical problems in development, especially for lifting and water flooding techniques which needs to be study. The project provides a set of techniques that meet the requirment of slim hole development including stratified waterflood, testing and debugging techniques of deep well(2000 meters), optimization design and disinvestment of lifting system, new lifting techniques, oil deposit monitoring, matching technique and tools of slim hole.
