Problems solved by technology

[0002] The glutenite sedimentary bodies not only have complex vertical and horizontal changes, but at the same time, due to the rapid change of glutenite fan body facies and various lithologies, the rock-electricity relationship is complex, the reservoir heterogeneity is extremely strong, and the reservoir connectivity relationship is spatially heterogeneous. Quality changes, resulting in large oil content differences and large changes in production capacity, which seriously affect the development effect

Embodiment Construction

[0023] In order to make the above and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments are listed below and shown in the accompanying drawings in detail as follows.

[0024] Such as figure 1 as shown, figure 1 It is a flow chart of the earthquake prediction method applicable to the sandy conglomerate sedimentary connected body in the steep slope zone of the present invention.

[0025] Step 101 , single-well curve correction and multi-well consistency processing restore the true response characteristics of the curve.

[0026] The quality of a single well logging curve firstly includes curve splicing, depth correction, etc. In addition, the logging curve is affected by the borehole environment (porous glutenite shrinks in diameter, mudstone collapses and expands), and the main realization process is that the reference is affected by the borehole environment For smaller curves, such as natural gamma ray (GR), resisti...

Abstract

The present invention provides an earthquake prediction method applicable to glutenite sedimentary connected bodies in steep slope zones, including: single-well curve correction and multi-well consistency processing to recover the real response characteristics of curves; Inter-stage interface; comprehensive study of seismic facies to understand the extension range of conglomerate bodies, and preliminarily determine the outer boundary of small stages; deterministic inversion and seismic phase fusion to determine facies control conditions; high-resolution post-stack facies-controlled geostatistical inversion Depict favorable conglomerate bodies; high-resolution post-stack facies-controlled geostatistical inversion and co-simulation to describe favorable physical property development areas; combine high-resolution facies-controlled geostatistical inversion and geostatistical co-simulation to describe the space of effective connected bodies distributed. This method can effectively describe the glutenite sedimentary body in the steep slope zone, predict the favorable physical property area, and then obtain the spatial distribution of effective connected bodies, providing key technical support for the efficient development of glutenite in the steep slope zone.

Description

technical field [0001] The invention relates to the technical field of oilfield development, in particular to an earthquake prediction method suitable for glutenite sedimentary connected bodies in steep slope zones. Background technique [0002] The glutenite sedimentary bodies not only have complex vertical and horizontal changes, but at the same time, due to the rapid change of glutenite fan body facies and various lithologies, the rock-electricity relationship is complicated, the reservoir heterogeneity is extremely strong, and the reservoir connectivity relationship is spatially heterogeneous. Quality changes, resulting in large differences in oil content and production capacity, seriously affecting the development effect. For this reason, we invented a new earthquake prediction method suitable for glutenite sedimentary connected bodies in the steep slope zone, which solved the above technical problems. Contents of the invention [0003] The purpose of the present inv...
