The parameter of fracture evaluation mainly comprises the density in crack, inclination angle and width, imaging logging new technology ratio is utilized to be easier to calculate fracture density, inclination angle, and the Obtaining Accurate of fracture width is comparatively difficult, it is also one of significant challenge faced in current logging evaluation.
At present, the detection method of fracture width mainly contains three major types: quantitatively detect according to the fracture width of al-lateral resistivity difference, detect according to the fracture width of high-resolution imaging well-log information and detect according to the fracture width of Stoneley wave attenuation amplitude.
When there is crack, in drilling process, slurry compounding is remarkable, due to depth bilateral to investigation depth different, therefore, slurry compounding is also different on the impact of resistivity, thus causes depth side direction resistivity there are differences.On numerical simulation study basis, a lot of scholar establishes the quantitative relationship between fracture width and al-lateral resistivity difference, but, fracture width is one of influence factor of deep and shallow resistivity difference, except fracture width, the size of the inclination angle in crack, the permeability on stratum itself, basement rock resistivity and reservoir water salinity etc. all have a significant impact to amplitude difference tool bilateral.Therefore, although according to bilateral to amplitude difference can carry out qualitative recognition by fracture, with regard to quantitative evaluation, its precision comparison is low.

The embodiment of the present invention provides a kind of method obtaining fracture width, and Fig. 1 is the process flow diagram of the acquisition fracture width method of the present embodiment, and this flow process comprises the steps:
S101, obtains object formation fracture interval full-hole core, there is a natural fracture in the middle of this full-hole core.
In this step, full-hole core chosen two principle:
(1) there is an obvious natural fracture in rock core, be easy in laboratory conditions with this crack for rock core is divided into two parts by boundary, and do not damage the natural form in crack; (2) rock core at two ends, crack is without another cracks or microfracture.
Select above-mentioned rock core to make fractured model to have the following advantages: first, adopt fissureless true core as the base portion of fractured model, can not contain pore structure characteristic and the physical parameter such as factor of porosity, permeability such as type, distribution of rift portion hole in Reality simulation stratum completely; Secondly, select the rock core with obvious natural fracture, be easy in laboratory make real fracture plane.
S102, with described natural fracture for full-hole core is divided into two parts by boundary, makes the fractured model with different fracture width.
S103, obtains the Stoneley wave relative amplitude of fractured model under different fracture width.
Stoneley wave relative amplitude can by carrying out shock tube experiment realization to selected full-hole core.Shock tube is the direct measurement mechanism of a kind of novel Stoneley wave, by shock tube experiment, directly can not only measure Stoneley wave, and can study the rule that fracture width, inclination angle and distribution etc. affect Stoneley wave.Utilize the fractured model with different fracture width made in step S102, accurately can be obtained the Changing Pattern of full-hole core Stoneley wave relative amplitude under different fracture width by shock tube experiment.
S104, calculates the parameter of equivalent crack opening model according to the Stoneley wave relative amplitude of fractured model under different fracture width.
In order to form the Analysis of Crack Width based on Stoneley wave, on, experimental study theoretical in early stage is basic, the present invention proposes a kind of new formula calculating equivalent crack opening according to Stoneley wave relative amplitude first:
