Research On Log Interpretation And Evaluation Of Low Resistivity Reservoir In Dongxin Oilfield

The reservoir resistivity in different region varies larger because of the influence of the structure, deposition and digenesis in dongxin Oilfield. The distinguish feature of classic reservoir in dongxin Oilfield is the variety of resistivity including low resistivity reservoir. The complex reservoir had produced the commercial oil and gas flow and because the main production reservoir. This document concerted on the origin of low resistivity reservoir and qualitative or quantitative interpretation including analysis of application in dongxin Oil field.Have investigated deeply the relation of resistivity and microscope pore structure, the relation of the parameter of log interpretation and pore structure, the relation of T2 destruction in NML and pore structure with capillary pressure of the half permeation barrier and lithology electronic experiment technology. Have built the method of determining microscopic pore structured parameter with the NML information.Have built the different qualitative and quantitative interpretation technology of the low resistivity reservoir according to the different type. The qualitative interpretation based on cross plot and interpretation chart. Have built the method of interpretation of variable m, n based on NML, evaluated the reservoir prosperity of movable water-bearing .Correlate the value of the oil saturation with the model of dual group structure.The research have got the evident geological application in dongxin Oil field.. And have mad the important contribution in exploration and development in this Oil field.
