Problems solved by technology

[0003] Strike-slip reformed basins refer to basins reformed by strike-slip fault activities in the geological history period. The reform results of such basins often manifest as spatial dislocation and incomplete remnants. It is very important to understand the prototype of the basin and objectively evaluate its resource potential and scale. cause serious hindrance

[0098] Example, Jurassic Basin Restoration in Western Qaidam Basin-Algin Area

[0099] Geological Profile

[0100] The Qaidam Basin is located in the northeastern part of the Qinghai-Tibet Plateau, bordered by the East Kunlun Mountains in the south, the South Qilian Mountains in the north, and adjacent to the Tarim Basin by the Altun Mountains in the west ( Figure 7 ), with an area of ​​about 12.1×10 4 km 2 . The basement of the basin is complex, with the dual basement of Pre-Sinian crystalline rock and Sinian-Triassic unmetamorphic-epimetamorphic rock. The basement in some parts of the central and western regions was intruded and transformed by Caledonian and Hercynian magmatic rocks.

[0101] The Altun structural belt is sandwiched between the Qaidam Basin and the Tarim Basin, and consists of multiple tectonic units formed in different periods. The Aktashtag complex, which is composed of Milan Group, TTG gneiss and Paleoproterozoic intrusive rocks, is widely exposed in ...

Abstract

A method for restoring the original sedimentary appearance of a strike-slip reformed basin, including the following steps: (1) Determine the strike-slip reformed basin, clarify whether the sedimentary body associated with the strike-slip fault has experienced strike-slip fault segment reformation, and further determine from 3 aspects to be determined and judged. For basins that have undergone strike-slip reformation, (2) synchronous strata-sediment relationship and (3) provenance relationship analysis should be carried out in sequence. Among them, the distribution patterns of paleocurrents and high-precision detrital zircon provenance tracing can indicate whether each residual basin has a common provenance area and the possible source area location. On the basis of the above three-step analysis, (4) estimate the dislocation distance and restore the original sedimentary appearance for the strata on both sides of the strike-slip fault in the same period. The objective restoration of its original sedimentary appearance is the basis for objectively understanding the paleogeographical appearance and basin-mountain paleo-tectonic pattern in the geological history period, as well as the basis for scientific evaluation of oil and gas resources and efficient exploration deployment, so its research significance is very important.

Description

technical field [0001] The invention belongs to the technical field of original basin restoration, and in particular relates to a method for restoring the original sedimentary appearance of a strike-slip reformed basin. Background technique [0002] Sedimentary basins (referred to as "basins") are areas where tectonic subsidence and sedimentary filling occur on the earth's surface. Basins are places where oil, gas, coal and other energy minerals accumulate. As a sedimentary entity with a specific spatial distribution formed during the geological history, basins often suffer from different degrees of transformation and damage after formation. The older the age, the stronger the transformation. Since the Mesozoic-Cenozoic, the sedimentary basins in China have been characterized by strong activity and strong late transformation due to the mutual influence of the activities of multiple tectonic domains in the coastal Pacific, Siberia and Himalayas. The restoration of the basin...
