Study on Low-Resistivity Characteristics and Genetic Mechanism of Putaohua Oil Layers in Songliao Basin

doi:10.3969/j.issn.1006-6535.2020.06.015

Abstract

Abstract: The Putaohua oil layers in the Songliao Basin are widely developed with low resistivity and has broad development prospects. However, their genesis is affected by many factors, their mechanism is complex, and they are difficult to be identified. Hence, it is hard to distinguish oil layer from water layer only from conventional well logging, which greatly limits the tapping potential of this kind of oil layer. In view of this difficulty, starting from the analysis of the characteristics of low-resistivity oil layers, the genetic mechanism of the low-resistivity oil layers was analyzed from 7 external and internal factors. The results show that sedimentary facies belt and clay mineral type, content and distribution form are the main controlling factors for the development of low-resistivity oil layers in this area. Structure and pore texcture, and interbedding sandstone and mudstone also have certain influence on the development of low-resistivity oil layers in this area, while mud invasion and salinity of oil-water layers have little influence on them. The research results have achieved good application results in the field practice of low-resistivity oil layer identification, which provides a more reliable geological basis for the evaluation and identification of this type of oil layers and the prediction of potential areas, and has important practical significance for increasing reserves and production in this area.
