Embodiment 1

[0033] An example of a new method for determining the fracturing ratio of volcanic rock reservoirs in an oilfield.

[0034] (1) Select a volcanic rock reservoir in an oilfield, collect the minimum horizontal principal stress curves of successfully fractured wells in the area, and calculate the "stress intrusion parameters" of all wells in the area. The calculation table is shown in Table 1:

[0035] Table 1 Calculation table of stress intrusion parameters of volcanic rock reservoirs in an oilfield

[0036]

[0037] (2) Collect the field data of the above reservoir fracturing, calculate the amount of sand added, and at the same time count the results of oil testing in the table. The specific calculation table is shown in Table 2:

[0038] Table 2 The fracturing data of volcanic rocks in an oilfield and the calculation form of sanding intensity

[0039]

[0040] (3) Combining the above two tables, extract the three items of the amount of sand added, the stress intrusion p...

Abstract

The invention discloses a method for determining the fracturing size of a volcanic reservoir. The method comprises the following steps of collecting minimum principal stress curve lines, determining perforation intervals, carrying out statistics on sand proportion data and formation testing result data, forming a board chart, and determining the sand proportion limit of the reservoir. The method improves the efficiency for predicating the fracturing size on site, and reduces the difficulty for predicating the fracturing size of a volcanic gas reservoir, requirements for technicians are relatively low, and the working efficiency and the economic benefit are improved.

Description

technical field [0001] The invention relates to the field of volcanic rock fracturing scale proportioning, in particular, the invention relates to a method for determining the fracturing scale of volcanic rock reservoirs. Background technique [0002] The determination of the fracturing scale of volcanic rock reservoirs is the basis for the success of volcanic rock reservoir stimulation. At present, the fracturing scale of volcanic rock reservoirs is mainly set by means of complex mathematical models and software predictions of various companies. Complex mathematical models have complex parameters and professional calculations, which have a high threshold; while software forecasting is simple, but the software source codes are technical secrets or related patents of various companies, and generally it is impossible to know the accurate forecasting method. Therefore, it is imminent to simplify the method for determining the fracturing scale of existing volcanic rock reservoi...
