Embodiment one:
As shown in Figure 1, the disclosed a kind of trap of this method embodiment is implemented method and is comprised:
Step 1: utilize pre-stack depth migration velocity field V (x, y, z) with pre-stack depth migration data H (x, y, z) by Depth Domain be converted to time domain data T (x, y, z);

1(z): computing formula is: H for x, y
1(x, y, z)=T (x, y, z) * V
1(x, y, z).
Embodiment two:
The skew of the forward modeling result data in KS area shows, time migration after stack also is difficult to geologic body skew playback under the situation of known formation true velocity, the relative master pattern in time migration after stack trap position is offset to the stratum downdip direction, pre-stack depth migration then can be with geologic body skew playback, and converting data also can be substantially with geologic body skew playback when dark accordingly.
Bore from real, converting data has significantly improved data skew playback precision when dark.The embodiment of the invention is as follows in the realization effect of this area:
1, the calibration result of drilling well shows that time migration after stack can not make high steep stratum and the mild stratum of angle be offset playback simultaneously simultaneously, if make high steep stratum skew playback, then the less stratum of angle then can overmigration, if make the skew playback of the less stratum of angle, angle layer significantly again can the side-play amount deficiency, converting data then can make the skew playback of different angle stratum simultaneously when dark, and the error basic controlling is within tolerance interval.
It is more reasonable to change the zone of interest skew when 2, real brill confirmation is dark, and high point, position of fault are also more identical with drilling well.
Influenced by pre-stack depth migration velocity field details less, reliable and stable for converting data when 3, dark.
4, accelerated exploration rhythm greatly.The storehouse car in front of the mountains cycle of a wheel well very long, often will be above 1 year, therefore every wheel well goes out must go up behind the result at once and bores the next round well location, if waiting for that pre-stack depth migration is handled at least again needs 2 months, and conversion is implemented trap again and only needed about 2 week when dark.
5, saved cost greatly, earthquake pre-stack depth migration reduced price in front of the mountains is high, and when dark conversion to implement trap cheap.
2010-2011 utilizes this technological achievement to carry out primary study in a plurality of work areas in the Tarim Basin, implements a plurality of structural trappings, on bore many mouthfuls of well locations, shortened research cycle, saved processing cost, advanced the gas prospecting in this district.
Embodiment three:
Restrain dark 1-2 3-D seismics work area and can be divided into three main synthems from top to bottom: salt suprastructure, gypsum-salt rock synthem, salt infrastructure.The salt suprastructure is high steep, and the exploration zone of interest is the salt infrastructure, buries dark.Because the ground floor height is steep, the skew playback of time migration after stack data is inaccurate, causes the design of KS1 well salt top to bore 1000m shallow than real.Though pre-stack depth migration skew playback is better than the time migration after stack data, because seismic data quality is poor, the ground floor height is steep, anisotropy is serious, causes data and real boring to differ greatly.This district's gas reservoir is subjected to structure control, and real the boring of KS1 well taken off zone of interest 132m gas-bearing formation, water breakthrough not, and the structure amplitude has only 50m on the pre-stack depth migration structural map, obviously is not inconsistent with real boring.KS101 well then pre-stack depth migration has then bored 300m dark than real.Because well error difference is big, mainly concentrates on and constructs on the axis, is difficult to simulate a suitable correction error trend surface, can not proofread and correct by the error trend surface and obtain rational structural map, cause estimating well location and dispose difficulty, gas reservoir is estimated difficulty.If handle, then be that cycle or expense all can't satisfy the demands and control the pre-stack depth migration that carries out a new round by new well data.Taked dark time conversion trap method that trap is implemented again at this district in this case.
Particularly, the embodiment of the invention is as follows in the realization effect of this area:
1, utilize the pre-stack depth migration velocity field to finish the dark time conversion of pre-stack depth migration data
Converting data is identical with pre-stack depth migration data structure vertical position when dark, demarcation by well, no matter be high steep stratum of shallow-layer or zone of interest, converting data skew accuracy all is better than the time migration after stack data when dark, substantially can be with geologic body skew playback.
2, converting data carries out the holostrome position and explains when dark
Utilize drilling data that earthquake, geologic horizon are carried out meticulous demarcation.Earthquake, well data, non-seismic facies are finished whole district's structure elucidation in conjunction with setting up the structure elucidation model, and the T0 that waits that obtains each layer position schemes.
3, utilize T0 such as each layer position figure to extract each layer position average velocity planimetric map.
To recently, the pre-stack depth migration velocity field is obviously unreasonable in western part, work area from zone of interest average velocity and well speed, and KSx4 well average velocity is lower than KSx1 well average velocity, and the pre-stack depth migration speed trend then in contrast.
4, utilize well speed degree, gravel bed to distribute to be familiar with each layer average velocity planimetric map is carried out plane correction, obtain final purpose layer average velocity planimetric map.
5, utilize each interval velocity planimetric map to become hasty map and obtain final structural map.
Become structural map to dispose to restrain wells such as dark 203,204,205,206,207,208 according to dark time conversion institute, wherein restrain dark 204 and restrain dark 207 and all bored and take off zone of interest, two mouthfuls of drilling wells show all when dark that it is that position of fault or structural feature substantially all match with the reality brill that conversion institute becomes structural map.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
