Problems solved by technology
[0005] The present invention mainly provides a method for constructing an underground oil depot by using abandoned coal mine shafts. This invention can not only solve the problem that some mine resources are gradually shrinking and exhausted in my country, and a large number of coal mines are abandoned, but also can increase crude oil and finished products to a certain extent. Reserves of national strategic resources such as oil

[0029] A method for constructing an underground oil depot using an abandoned coal mine shaft, a specific implementation is as follows:
[0030] Such as figure 1 , figure 2 , image 3 As shown, a method for constructing an underground oil depot utilizing abandoned wells and lanes includes the following steps:
[0031] a) Collect geological data during coalfield geological exploration, roadway development, and coal seam mining, and determine the distribution characteristics of rock formations, faults, and cracks in shafts and roadways;
[0032] b) Measure the oil seepage characteristics of the wellbore and roadway passing through different lithology rock formations, and judge whether the rock formations in the wellbore and roadway have oil storage conditions according to the test results; for the rock formations in the wellbore and roadway that do not have oil storage conditions locally, use plugging The method is sealed to make it reach the condition of oil storage;

The invention discloses a method for building an underground oil depot by utilizing an abandoned coal mine well lane. The method for building the underground oil depot by utilizing the abandoned coalmine well lane comprises the steps of collecting geological data in the period of coal geology exploration, laneway exploiting and coal mining, and determining distribution characteristics of rock stratums, faults and fractures in a shaft and a laneway; determining oil permeability characteristics of the shaft and the laneway penetrating through the rock stratums with different lithology, and judging whether the rock stratums has oil storage conditions or not; carrying out leaking stoppage on the faults, the fractures and the high-permeability coal rock stratums, and preventing stored oil leakage; building a sealed space in a rubber belt main laneway, and isolating the rubber belt main laneway into oil depot chambers with different lengths ranging from 200 to 300m; through reconstructing the bottom part and a wellhead of a main well, enabling the main well to become a complete oil depot well; and reconstructing a power supply system, a ventilating system and a drainage system in an abandoned mine well, and meeting the demands of firefighting, ventilating and water supplying and draining functions of the oil depot. According to the method for building the underground oil depot by utilizing the abandoned coal mine well lane provided by the invention, the underground space resources of the abandoned mine well are fully utilized, and the built underground oil depot has the characteristics of concealment, safety and strategic performance.
Description
technical field [0001] The invention relates to a construction method of an underground oil depot, in particular to a method for constructing an underground oil depot by utilizing an abandoned coal mine shaft, and belongs to the field of underground space utilization of an abandoned coal mine. Background technique [0002] Due to the non-renewable mineral resources, the mines have been exploited for a long time, and the resources have gradually shrunk and dried up. Well-preserved shafts, track alleys, belt alleys, etc. after abandoned mines are rare underground space resources. Reasonable use of underground space resources in abandoned mines can bring better economic benefits. For example, patent CN 107119710A discloses an underground city construction method based on abandoned mines, and patent CN 107676132A discloses a method for placing waste concrete and sequestering carbon dioxide in old abandoned mines. This shows that using the underground space resources of abandone...
