Problems solved by technology

However, the traditional method of measuring oil content in the laboratory or using logging data to calculate the oil content of oil shale is expensive, the process is time-consuming, discontinuous, or requires more logging data, which cannot be achieved in the field or at the drilling site. Quickly obtain oil content data to judge the quality of oil shale

Embodiment

[0048] In order to facilitate the understanding of the solution provided by the present invention and its effects, a specific example is given below. It should be understood by those skilled in the art that this embodiment is only for facilitating the understanding of the present invention, and any specific details thereof are not intended to limit the present invention in any way.

[0049] Take the oil shale core of an exploration well in a domestic oil shale mining area as an example.

[0050]Step 1, first, use a portable ore element analyzer to measure the element percentage of a certain oil shale sample at the drilling site, and obtain the percentage content of each element in the oil shale, mainly including (Si, Al, Fe, Ca, K, S and other elements); then, the percentage contents of S and Al elements that are well correlated with oil content are separated and sorted out, which are 0.994% and 4.511%, respectively;

[0051] Step 2: Based on the oil content of the oil shale ...

Abstract

The invention discloses a method for calculating the oil content of oil shale. The method comprises: obtaining the percentage contents of S element and Al element in the oil shale sample based on the oil shale sample; The oil shale oil content data measured by the laboratory of the oil shale mining area where it is located is obtained through multiple regression analysis to obtain calculation coefficients and establish the oil shale oil content regression equation; M=a+bC S +cC Al , where M is the oil content of oil shale, C s and C Al are the percentage content of S element and Al element respectively, a, b, and c are calculation coefficients; based on the percentage content of the S element and Al element and the oil shale oil content regression equation, the oil shale oil content is obtained . The method provided by the present invention can realize the rapid calculation of the oil content of the oil shale through the obtained percentage content of the S element and the Al element and the regression equation of the oil content of the oil shale.

Description

technical field [0001] The invention relates to the technical field of formation oil content detection, and more particularly, to a method for obtaining oil shale oil content. Background technique [0002] The existing oil shale oil content determination mainly includes low temperature dry distillation method, logging interpretation method and rock pyrolysis method. The low-temperature retort method is mainly used in the laboratory to measure the oil generation from oil shale pyrolysis by low-temperature retort of aluminum shale to determine the oil content. This method is time-consuming, expensive, and the data is discontinuous. The logging interpretation method is to use the oil shale logging data to analyze and calculate the oil content, mainly including the following two methods. The regression analysis method is used to calculate the oil content of oil shale; the other is proposed by Wang Cuiping in 2011, the method for measuring the oil content of oil shale micro-pore...
