Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0022] Considering the research defects in deep oil and gas exploration in the prior art, the inventors used the oil-generating and gas-generating attributes of various rocks in the ancient microbial source rocks in the work area, and the plane distribution characteristics of the ancient microbial source rocks to obtain different positions in the work area. The corresponding oil and gas generation attributes ultimately guide oil and gas exploration.

[0023] Specifically, in this example, a source rock distribution and oil and gas exploration method are provided, such as figure 1 As shown, the...

Abstract

The present invention provides a source rock distribution and oil gas exploration method and device. The method comprises the steps of: determining compositions of source rocks, and determining oil and gas generation properties of various rocks in the source rocks; on the basis of the oil and gas generation properties of various rocks in the source rocks and plane distribution characteristics of the source rocks, obtaining the oil and gas generation properties of each zone in a work area; carrying out oil and gas exploration according to the oil and gas generation properties of each zone in the work area. In the embodiments of the present invention, the new method for efficiently and accurately predicting the hydrocarbon generation potential of deep ancient microbial hydrocarbon source rocks is proposed, which fills the gap of deep oil and gas exploration in the oil exploration and development industry. By quickly determining the distribution of ancient microbial source rocks in the work area and the corresponding oil and gas generation potential of different areas, a reasonable deep oil and gas exploration plan can be made, which can further accelerate the efficiency of deep oil and gas exploration and achieve the purpose of efficient exploration of deep ancient strata oil and gas.

Description

technical field [0001] The invention relates to the technical field of petroleum exploration, in particular to a method and device for hydrocarbon source rock distribution and oil and gas exploration. Background technique [0002] At present, with the continuous deepening of petroleum exploration, the field of petroleum exploration is becoming more and more complex, and the resources of petroleum exploration are becoming more and more inferior. Therefore, geological exploration to deep ancient strata has become an inevitable trend of petroleum exploration development. [0003] Hydrocarbon source rocks include oil source rocks, gas source rocks and oil and gas source rocks. The source rocks of ancient microbial origin discovered in recent years are mainly distributed in the deep Cambrian, where the organic matter accumulation is mainly caused by the proliferation of microorganisms such as cyanobacteria, and finally high-quality source rocks are formed. [0004] However, sour...
