Logging Reservoir Evaluation Of Wu-xia Area In Junggar Basin's Northwest Edge

In recent years, many important developments have been achieved in the reservoir prospecting of Wu-xia Area in Junggar Basin's Northwest Edge. The reservoir analysis and evaluation are even more integrant, logging plays an important part as a mean .The paper establishes the logging index evaluation model by the research of this area and also makes an effect reservoir logging evaluation.To grit reservoirs, making use of core analyzing, oil testing, well copy, substance analyzing, researching the grit reservoir's logging responding characters, we establish the logging evaluation models of relevant reservoirs such as porosity,permeability,saturation. Logging evaluations are finished successfully. It makes well in oil field's producing work.To volcanic reservoirs, a series of math's methods are used to carve up the volcanic rock reservoirs, by using logging faces techniques, also combining the data of core analyzing,oil testing,well copy,substance analyzing.The logging evaluation models are made up on the basis of the rock identifying, which make the matter of heterosphere changed to homosphere and make the nonlinear logging models changed to linear ones, also realize the idea of "rock scaling logging". According to the Volcanic Reservoir's distribution and structures of the researching zone, using all available logging data, The research of fractures is done to analyzing the relationship between the fractures and the faults. It offers a strong approach of studying on the rules of reservoirs distributing.
