Problems solved by technology

[0012] At the same time, the restoration of paleogeomorphology during the sedimentary period is still based on the traditional analysis of sedimentary facies, and the outline of paleogeomorphology is roughly reflected by columnar section comparison charts; it cannot fully reflect the paleogeomorphology, which affects the research on sedimentation and reservoirs Work

Embodiment 1

[0048] The Ordos Basin is divided into 6 first-order tectonic units: the west margin thrust belt, the Tianhuan Sag, the Yimeng Uplift, the Yishan Slope, the Jinxi disturbance belt, and the Weibei Uplift. The thrust belt at the western margin and the disturbing curve belt in the west of Shanxi are structural units with strong structural deformation. The Yishan slope and the southern margin of the Yimeng uplift are areas with very weak structural deformation. The sedimentary period of marine carbonate rocks on the Yishan slope showed a structural pattern of high in the northwest and low in the southeast ( image 3 ).

[0049] The eastern part of the Sulige gas field is located on the northeast side of the Yishan slope in the Ordos Basin structurally, and on the south side of the Yimeng uplift. Geographically located in the east and north of Wushen Banner. The average well spacing in the work area is 800 meters. During the Ordovician sedimentary period, it was high in the nort...

Abstract

The invention provides an inversion method of microscale deposition stage palaeogeomorphology in a weak construction deformation range, and the method comprises the steps of 1 determining a current construction of a work area, namely determining a trend surface of the current construction; setting the distance between the current construction surface in vertical direction and a trend amplitude wire as a proposed construction amplitude; subtracting trend surface landform data from the current construction landform data to get proposed construction amplitude data; 2 determining a deposition stage construction trend surface; and 3 adding the deposition stage construction trend surface and the proposed construction amplitude data obtained from step 1 to get a deposition stage palaeogeomorphology. <{EN2}>According to the method, the distribution heterogeneity of high-quality reservoirs can be known when exploiting gas fields that has an area of only hundreds of square kilometers and a well spacing of 1000 meters or less; and the success rate for well encryption can be raised.

Description

technical field [0001] The invention belongs to the field of geological and mineral exploration, and in particular relates to a geomorphic data inversion method. Background technique [0002] The significance of paleogeomorphology to reservoirs, especially carbonate reservoirs, can be discussed from two perspectives: sedimentary paleogeomorphology and denudation paleogeomorphology. First, paleogeomorphology in the sedimentary period is the key factor controlling the development of sedimentary systems, and marine sedimentary paleogeomorphology plays an important role in controlling carbonate reservoirs such as reefs and tidal shoals. It is generally believed that organic reefs are developed on fault-uplift platforms and their platform margin slopes, and favorable tidal shoal reservoirs are developed in hydrodynamic high-energy areas on top of underwater low uplifts. Second, denudation paleogeomorphology (karst highlands, karst slopes, and karst valleys) plays an important ro...
