Reservoir Comparison and Exploration Enlightenment of Baikouquan Formation in Northern and Western Slopes of Mahu Sag

doi:10.7657/XJPG20220103

Abstract

Abstract:

Major breakthroughs to oil and gas exploration have been made in the northern slope of Mahu sag, but little exploration effect has been obtained in the adjacent western slope. According to the data from cores, thin sections and scanning electron microscope, the petrological characteristics and diagenesis of the Baikouquan reservoirs in the northern and western slopes are compared and analyzed. It is found that the reservoir physical properties and controlling factors are very different, and compaction, cementation and dissolution are fundamental causes for the different reservoir physical properties. The western slope is better than the northern slope in oil and gas resources. Favorable reservoirs are distributed in the deep of the western slope, and future exploration should focus on the two wings of the fan delta and the area around Well Mazhong-1.

Key words: Mahu sag, northern slope, western slope, Baikouquan formation, reservoir feature, controlling factor, exploration enlightenment
