Description
(1) technical field: the invention belongs to rock pyrolysis life, oil-saturated reservoir rock proximate analysis
Technical field.
(2) background technology: at present, method for qualitative analysis is adopted in rock pyrolysis life, the oil-saturated reservoir rock proximate analysis adopted in the world more, can solve the problem that some aspects are analyzed in current geologic prospecting, but can not determine the absolute content of component, can not specifically measure the accurate numerical value (every gram rock contains a milligram hydrocarbon number) of oily.
(3) summary of the invention: the objective of the invention is for life, oil-saturated reservoir rock are carried out accurate quantitative analysis, accurately to determine oil and gas reserves.
The pyrolysis gas that sample (1) is pushed the generation of pyrolysis oven (2) back divides two-way to detect, and every road is 50% of a gas gross.One tunnel pyrolysis gas enters detecting device (3) and mainly detects total hydrocarbon amount living, oil-saturated reservoir rock, and another road pyrolysis gas enters isolator (4), and isolator (4) is outer is full of the stove silk, and adsorbent is housed in the cavity.Because the temperature of isolator (4) is lower than pipe temperature slightly, so be detained to get off by the heavy component in the pyrolysis gas of isolator (4), remaining component 1,2 by T-valve (5) enter six-way valve (6), capturing carbon number from 2,1 of six-way valve (6) by heavy hydrocarbon drip catcher (7) again is material more than 10, and remaining carbon number is that 1-10 material is captured by lighter hydrocarbons drip catcher (8).After this road has captured, T-valve (5) is transformed into 1,3 states of connecting automatically, pyrolysis gas is by 2,1 arrival heavy hydrocarbon drip catcher (11) of six-way valve (10), the capture carbon number is the material more than 10, and remaining carbon number is that 1-10 material is captured by lighter hydrocarbons drip catcher (12).After this road has captured, change simultaneously six-way valve (6) and (10), and to heavy hydrocarbon drip catcher (7) and (11), lighter hydrocarbons drip catcher (8) and (12), isolator (4) heats simultaneously, the post carrier gas is from D, the E point is blown into, enter 5 of six-way valve (6) and (10) respectively, 4 points, with lighter hydrocarbons drip catcher (8) and (12), component in heavy hydrocarbon drip catcher (7) and (11) is by six-way valve (6), (10) 1,6 blow to separation detecting system (9), (13), separate respectively and detect, detection system (9) detects rock gas content and evaporation hydrocarbon content, and detection system (13) detects pyrolysed hydrocarbon content.Meanwhile, solenoid valve (14) is also opened, blowback air oppositely enters T-valve (5) by 2,1 of this solenoid valve and 3,2 of six-way valve (10), and naming a person for a particular job by 3,1 of this T-valve is trapped in component in the isolator 4 and blows back detecting device (3) and detect.
