Embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further described.
See Fig. 1 and Fig. 2, embodiments providing a kind of shale gas volume fracturing micro-seismic monitoring method, the method comprises the steps:
Step 101: according to factors such as the maximumization monitoring range of shale gas platform well, instrument deployed position cementing quality, background noise and practice of construction demands, select monitor well in shale gas platform well.
Maximumization monitoring range according to shale gas platform well, in platform, fractured well need in monitoring range; Instrument deployed position need to avoid the position of cementing quality difference; Get rid of noise source, avoid same platform, fractured well to cause inter-well interference with falling liquid level. Shale gas platform well optimizes monitor well, to realize micro-seismic event monitoring by this monitor well, ensures the accuracy of monitoring result. Individual well monitoring can be carried out, it is possible to monitor many mouthfuls of fractured wells simultaneously.
Step 102: adopt gaslift mode that monitor well liquid level is down to 300 meters, below ground.
Owing to fractured well and monitor well are in same job platform, therefore in fracturing process, pump truck can bring very big background noise impact to well seismometer. In order to reduce the impact of background noise, gaslift mode can be adopted to reduce monitor well liquid level, can effectively reduce noise when micro-seismic event is monitored like this, thus reduce background noise to the impact of micro-seismic event monitoring result.
Step 103: the straight well section at monitor well arranges high sampling rate wave-detector.
The high sampling rate wave-detector of the present embodiment is three-component seismometer. The sampling rate of three-component seismometer is 4KHz, and bandwidth is 0-1660Hz, and its sampling precision compared to conventional wave-detector (2KHz) high 2-3 doubly, can improve the positioning precision of micro-seismic event so greatly.
Step 104: utilize logging trace to set up initial velocity model.
Existing logging trace is utilized to extract the initial interval velocity model obtaining stratum media. Specific implementation method is the methods such as the assorted conversion of middle value filtering or Wal.
Step 105: utilize perforation event or primacord fuse initial velocity model to be calibrated, and high sampling rate wave-detector is carried out orientation correction.
When carrying out speed calibration, normally determined the medium velocity of this pressure break section by the perforation information of staged fracturing. First set up perforation or primacord fuse actual walk time with theoretical walk time objective function, then realize the iteration to existing initial velocity model upgrade by solving its minimum value. Owing to the perforation distance high sampling rate wave-detector of some pressure break section of shale gas platform fractured well is far away, it is thus desirable to first determine whether high sampling rate wave-detector can monitor perforation event, if monitor less than, then should locating wave-detector at this fractured well straight well section detonation primacord fuse, primacord fuse medicine amount should not be less than 200 grams. Error between the micro-seismic event position that medium velocity after use correction calculates and the micro-seismic event position of reality is less than 5 meters, meets the monitoring accuracy requirement of micro-seismic event. In addition, well geophone decentralization process may occurring, wave-detector level orientation rotates, cause wave-detector level orientation and the inconsistent situation of pre-configured orientation, it is thus desirable to carry out the correction of well seismometer orientation. The method that three component seismic data carries out polarization analysis is generally adopted to determine wave-detector deflection angle.
Step 106: original microearthquake signal is carried out the pre-treatment such as rotation of horizontal component and filtering.
Result is corrected according to high sampling rate geophone orientation, the original microseismograms of horizontal component that it receives is carried out rotation of horizontal component, the rotation of horizontal component that each wave-detector is observed to consistent coordinate system, to improve the first arrival continuity of waveform, it is to increase follow-up first break pickup precision. Spectrum signature according to original microseismograms, carries out corresponding filtering process to it, with the interference of press portion ground unrest.
Step 107: the microseismograms received according to high sampling rate three-component seismometer, utilizes the initial velocity model after calibration and optimization, calculates the generation position of micro-seismic event in fracturing process, and show micro-seismic event information.
According to the signal to noise ratio of micro-seismic event that high sampling rate wave-detector receives, the first break time that when utilizing length, window carries out compressional wave (P ripple) and shear wave (S ripple) than method (STA/LTA) is picked up automatically; Specifically, during length, window is drawn by following formulae discovery than method (STA/LTA):
Wherein, R is energy ratio between the long window and the short window value, l1,l2Be respectively setting window in short-term and long time window, generally get l2=10l1, w (j) is wave-shape amplitude value corresponding to moment j, when the moment that R value is undergone mutation, it will be recognized that be the first break time of compressional wave or shear wave.
The velocity of propagation of first arrival according to ripple in length and breadth and in length and breadth ripple, calculates the generation position of micro-seismic event in fracturing process. Specifically, the generation position of micro-seismic event is drawn by following formulae discovery:
[(xpi-xqk)2+(ypi-yqk)2+(zpi-zqk)2]1/2=�� Tki��vp��vs/(vp-vs)
Wherein, wherein, (xpi,ypi,zpi) it is the volume coordinate (known) of described monitoring well geophone i, (xqk,yqk,zqk) it is the generation position coordinate of micro-seismic event, �� TkiFor ripple in length and breadth walks the time difference, v to wave-detector ip,vsIt is respectively the velocity of propagation of longitudinal and transverse ripple.
On-the-spot at pressing crack construction, micro-seismic event can be screened, process and explain by geophysical project teacher in real time, to adjust fracturing technology controling parameters in time; In addition, by manual type, micro-seismic event is explained, it is possible to prevent background noise event to the misleading instructing pressing crack construction.
The shale gas volume fracturing micro-seismic monitoring method that the embodiment of the present invention provides, by preferred monitor well and the three-component seismometer rationally arranging high sampling rate, and the speed model combining correction and optimizing, greatly increase the precision of shale gas platform well micro-seismic monitoring, especially for the communication barrier occurred in platform well fracturing process or natural fracture, cover leakage waits geologic anomaly situation, pressure-break form is carried out in real time, accurately portray, Real-Time Monitoring pit shaft integrity, in time for on-the-spot fracturing engineering teacher proposes reasonable proposal, and pressing crack construction recruitment evaluation can be provided. the embodiment of the present invention provide shale gas volume fracturing micro-seismic monitoring method, Changning, Sichuan area successful Application 2 platforms, obtain good effect, it is achieved that to shale gas platform well with pressure Real-Time Monitoring.
