Abstract

Abstract:

The reservoirs of Lucaogou Formation in Jimsar Sag of Junggar Basin distributed alternately in high quality source rock layer series. There are two sets of unconventional reservoirs in the upper and lower segments and show typical tight oil characteristics of various lithologies, strong heterogeneity and micron-nanometer pore with oil. The original experimental analysis technology for conventional reservoirs is not satisfied for the need of further exploration and development of tight oil. Based on targeted experimental analysis technology, such as coordinated measurement of multi-parameter, exploration of wash oil, measurement of porosity-permeability and wettability of tight oil core and staining technique of carbonate minerals, this paper studied the typical tight oil characteristics of lithologies, physical properties, oiliness and their inherent correlation. The new achievements not only provide aboundant experimental materials to deepen geological understanding for the tight oil of Lucaogou Formation in the Jimsar Sag, but also effectively promote the exploration and development in this area.

Key words: experimental analysis technology, tight reservoirs, Lucaogou Formation, Permian, Jimsar Sag, Junggar
