Main controlling factor analysis for shale oil production and earthquake prediction method and device

Abstract

The invention discloses a main controlling factor analysis for shale oil production and an earthquake prediction method and device. The main controlling factor analysis for shale oil production and the earthquake prediction method and device are characterized in that the main controlling factor analysis for shale oil production is capable of establishing a shale oil and gas reservoir accumulation mode which plagues scientific research workers from a long time by means of analyzing shale oil and gas accumulation conditions, oil and gas geological characteristics and oil and gas accumulation characteristics; the earthquake prediction method and device conducts prediction by selecting a targeted earthquake prediction technique to ultimately realize comprehensive prediction of oil and gas enrichment region of a shale oil reservoir in Langzhong area of Sichuan province; the main controlling factor analysis for shale oil production and the earthquake prediction device mainly comprises a driller, a lifting base, an acoustic detector, a camera, a sensor, an analysis computer and a storage printer. Furthermore, the main controlling factor analysis for shale oil production and the earthquake prediction method and device determines main controlling factors of shale oil drilling production in Daanzhai section of Langzhong area to predict favorable areas for oil and gas via a corresponding earthquake and geological prediction technique, thereby improving oil recovery efficiency and laying the foundation for the further exploration of shale oil and gas in Sichuan area.

Description

technical field [0001] The invention belongs to the technical field of oil and gas exploration, and in particular relates to a method and equipment for analyzing main controlling factors of shale oil production and earthquake prediction. Background technique [0002] Shale oil and gas refers to oil and gas that is self-generated and self-storage in argillaceous source rock formations without secondary migration, including oil and gas that occurs in source rock pores, natural fractures, carbonate rocks, and sandstone interlayers (6- 10% porosity, <0.1mdpermeability); conventional oil and gas refers to the formation of hydrocarbon accumulation in the reservoir after secondary migration, including tight oil and gas accumulated in tight reservoirs such as low-porosity and low-permeability sandstone and siltstone (6 -10%porosity, <0.1mdpermeability). [0003] 1 Overview of shale oil [0004] 1.1. Characteristics of shale oil accumulation [0005] ① Shale oil has the char...
