纯油条件下合成碳酸盐岩烃类包裹体及其捕获机制探讨
Synthesizing hydrocarbon inclusions in carbonate with pure oil and discussion of its trapping mechanism
摘要
Abstract
The experiment which temperature and pressure were near the condition ofnatural reservoir was carried out to synthesize hydrocarbon inclusions in carbonate within pure oil. Through the microscopic and fluorescent characters of hydrocarbon inclusions in carbonate, it demonstrated that carbonate remained growing and trapping inclusions when fluid medium was pure oil. The water was not necessity for trapping hydrocarbon inclusions in growing carbonate. Combined with conclusions of predecessors and wettability determination of carbonate, the trapping mechanism of hydrocarbon inclusions in carbonate was concluded as follows: coexistence of oil and water( water wetted), coexistence of oil and water ( oil wetted) and pure oil. Under the conditions of water wetted, the mineral matter for carbonate growing was supplied by water solution. The speed of carbonate growing was relatively quick and quantity of synthetic hydrocarbon inclusions was big. Under the conditions of oil wetted, the mineral matter was supplied by both water solution and polar component of oil. Under condition of pure oil, the mineral matter was supplied by polar component of oil and organic acid generated when oil cracking. The mineral matter was limited, so carbonate growing was constrained and quantity of hydrocarbon inclusions was little.关键词
