Problems solved by technology

[0006] (4) Inconsistent stratum thickness, sedimentary facies and occurrence on both sides of the fault;
However, not all strike-slip faults have oil and gas shows. For example, the complete Tanlu fault has a wide range, and oil and gas reservoirs have only been found in some intervals such as the Bohai Bay Basin and Subei Basin; No oil and gas reservoirs found in the surrounding area

Embodiment Construction

[0063]The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0064] The mantle-derived oil and gas theory believes that in addition to the upper crust, there are three air circles in the middle and lower crust (below the depth of 10000m to the Moho surface), the upper mantle, and the core, plus the upper crust, there are four air circles in total. The discovered oil and gas reservoirs are only a small part of the upper crustal atmosphere, and communicate with the lower crustal atmosphere. Some of the oil and gas reservoirs to be searched by the mantle-derived oil and gas theory are distributed in the upper crust (a part has been discovered according to the traditional theory, but some have not been discovered), and more parts are distributed in the middle and lower crust (that is, the low velocity, low resistance, low-density body), the current engineering and technical means can already support...

Abstract

The invention relates to the technical field of petroleum and natural gas exploration, and discloses an exploration method for oil and gas reservoirs controlled by strike-slip faults, including: describing the strike-slip structural form of the target area through three-dimensional seismic data, and finding specific reservoir-controlling parts in the strike-slip fault; Low-velocity, low-resistivity, and low-density body locations are used to determine deep hydrocarbon sources; further, through rock mineralogical analysis and geochemical means to confirm whether there is a deep heat source in the formation corresponding to the reservoir-controlling part obtained by S1; further, through surface exploration and combined with The well logging and logging data of the existing wells confirm that there are oil and gas shows in the parts with deep heat sources obtained by S3; finally, through the finite element stress analysis, the favorable oil and gas enrichment areas are determined. Through the above steps, the location of the oil and gas reservoir controlled by the target strike-slip fault can be accurately determined.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration, in particular to an exploration method for oil and gas reservoirs controlled by strike-slip faults. Background technique [0002] Strike-slip faults are faults in which the two plates of the fault move relatively horizontally along the strike. Its basic features are straight fault lines, steep sections and narrow fault zones, which can be divided into left-handed and right-handed. Strike-slip faults can be divided into large, medium and small strike-slip faults according to their cutting depth, strike-slip distance and oil and gas geological characteristics. The petroleum geology community has formed a complete set of standards on how to identify strike-slip faults: [0003] (1) Most of the cross-sections are slow up and steep down, close to upright in the deep part, and directly inserted into the basement; [0004] (2) Flower-like structure developed on the profile; [0005] (...
