The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in further details.At this, exemplary embodiment of the present invention and explanation thereof be for explaining the present invention, but not as a limitation of the invention.
The embodiment of the present invention provides a kind of horizontal well Geological Prediction method, as shown in Figure 1, comprises the following steps:
Step 101: according to the horizontal segment position of the straight well position of finishing drilling and described horizontal well in work area, horizontal well place, the virtual well location that is identified for the horizontal well Geological Prediction is put;
Step 102: according to the oil reservoir section of the straight well of described finishing drilling, determine the oil reservoir section of described virtual well;
Step 103: according to the oil reservoir section of described virtual well, determine the oil reservoir section of the horizontal segment of described horizontal well;
Step 104: according to the oil reservoir section of the horizontal segment of described horizontal well, carry out Geological Prediction.
In the above-described embodiment, according to horizontal well, being positioned at the straight well position of the finishing drilling in same work area, and the location positioning of the horizontal segment of horizontal well goes out the position of virtual well, and then determine the oil reservoir section of virtual well according to the oil reservoir section of the straight well of finishing drilling, and dope the oil reservoir section of the horizontal segment of horizontal well according to the oil reservoir section of virtual well, finally according to the oil reservoir section of the horizontal segment of horizontal well, carry out the Geological Prediction of horizontal well.By the way, efficiently solve prior art in the situation that the control degree of well is not high, the technical problem that can't effectively be predicted the geology of horizontal well, reached in the situation that the not high effective prediction realized the geology of horizontal well of the control degree of well, enlarged the deployment scope of horizontal well and improve the technique effect of the accuracy of disposing.
In order to realize that more accurately determined virtual well can be positioned on the horizontal segment of horizontal well to the prediction of the oil reservoir section of the horizontal segment of horizontal well, or on the extended line of horizontal segment.The virtual well of determining like this is because be located along the same line with the horizontal segment of horizontal well, so to the predicting the outcome of the oil reservoir section of virtual well, also just closer to the oil reservoir section of the horizontal segment of horizontal well.
Position for the virtual well of how to confirm can be as shown in Figures 2 and 3, the position view of the straight well (referred to as drilled well) of the horizontal well based on shown in Fig. 2 and finishing drilling on every side, wherein, comprise: the first finishing drilling straight well 201, second finishing drilling straight well 202, the 3rd finishing drilling straight well 203, the 4th finishing drilling straight well 204, the 5th finishing drilling straight well 205, horizontal well 206, wherein, 2 two end points that mean horizontal well 206 horizontal segments of A and B.Can come in accordance with the following methods to determine the position of virtual well, comprise:
1) determine in work area, horizontal well place two place, finishing drilling straight well position straight lines;
2) by two place, finishing drilling straight well position straight lines, with the intersection point of the horizontal segment of the described horizontal well position as the virtual well of determining, or using two the intersection point of finishing drilling straight well position place straight line and the extended line of the horizontal segment of described horizontal well as the position of definite virtual well.
It should be noted that, above-mentioned by two the position of finishing drilling straight well at most only can determine the position of a virtual well, in the situation that a plurality of straight wells of finishing drilling are arranged, combination of two just can be determined the position of a plurality of virtual wells, therefore, as long as determine that according to above-mentioned the mode of the position of a virtual well operates the position that just can determine a plurality of virtual wells.
Just can obtain in the manner described above two virtual wells (virtual well 1 and virtual well 2) as shown in Figure 3, wherein, the first virtual well location is in the horizontal segment (line segment AB) of horizontal well 206 and the second finishing drilling straight well and the 3rd intersection point place of finishing drilling straight well place straight line, and the second virtual well 202 is positioned at extended line and the 4th finishing drilling straight well 204 and the 5th intersection point place of finishing drilling straight well 205 place straight lines of the horizontal segment (AB) of horizontal well 206.The first virtual well 301 and the second virtual well 302 determined by the way all are positioned on the horizontal segment of horizontal well.As long as determined that like this oil reservoir section of the first virtual well 301 and the second virtual well 302 just can effectively dope the oil reservoir section of the horizontal segment of horizontal well.
In the process of implementing, if the quantity of the straight well of finishing drilling is many, can as Fig. 3, determine so the first virtual well 301 and the second virtual well 302, yet, in the process of implementing, consider and also likely only have the 4th finishing drilling straight well 204 and the 5th finishing drilling straight well 205, and there do not is the second finishing drilling straight well 202 and the 3rd finishing drilling straight well 203, or only have the second finishing drilling straight well 202 and the 3rd finishing drilling straight well 203, and there do not is the 4th finishing drilling straight well 204 and the 5th finishing drilling straight well 205.So also just can only determine a virtual well.For above-mentioned two situations, provide in embodiments of the present invention following two kinds of processing modes:
1) in the situation that only determine a virtual well, according to the oil reservoir section of this virtual well of determining, and be positioned at the oil reservoir section of the straight well of the finishing drilling on the extended line of horizontal segment of horizontal well, determine the oil reservoir section of the horizontal segment of horizontal well; That is, if only determine a virtual well (supposing only to determine the first virtual well as shown in Figure 3), so just can be according to the first oil reservoir section of finishing drilling straight well, and the oil reservoir section of the first virtual well carrys out the oil reservoir section of the horizontal segment of prediction level well.
2) in the situation that determine more than a virtual well, according in a plurality of virtual well of determining, with the oil reservoir section of nearest two the virtual wells of the mid point of the horizontal segment of horizontal well, determine the oil reservoir section of the horizontal segment of horizontal well to be measured.; if determine two or more virtual well; can select so wherein two the nearest virtual wells of mid point apart from the horizontal segment of this horizontal well to be measured; determine the oil reservoir section of the horizontal segment of horizontal well; because the oil reservoir section situation in the zone of near distance is also close, the result that the oil reservoir section of the virtual well by close together is determined also just more approaches the truth of the horizontal segment oil reservoir section of horizontal well.
In the process of implementing, the horizontal segment that also may appear at horizontal well to be measured only has a straight well of finishing drilling, the situation of individual well namely, so in this case just need to be in conjunction with the structure in work area, adopt the mode of extrapolation (, the supposition of outwards extending of the individual well of the finishing drilling based on current) determine a virtual well, and the oil reservoir section of this virtual well.
In the oil reservoir section of the horizontal segment of above-mentioned horizontal well is determined method, the prediction one of the oil reservoir section related to has two places, one the oil reservoir section of virtual well is predicted, one is to predict the oil reservoir section of the horizontal segment of horizontal well to be measured according to the oil reservoir section of virtual well.Wherein, determine that according to the oil reservoir section of the straight well of finishing drilling the oil reservoir section of one or more virtual wells can comprise: according to two oil reservoir sections of the straight well of finishing drilling, dope the oil reservoir section of virtual well, wherein, described two the straight well position of finishing drilling be positioned at and determine on the straight line that this virtual well location puts.
The principle of this forecasting process institute foundation is that the variation of oil reservoir section in the same horizontal line is generally regular.For example, as shown in Figure 3, the 4th finishing drilling straight well 204, the 5th finishing drilling straight well 205 and the second virtual well 302 have been in the same horizontal line, because, the 4th finishing drilling straight well 204 and the 5th finishing drilling straight well 205 be all the well of finishing drilling, therefore the oil reservoir section of these two straight wells can directly measure, suppose that the result that measures as shown in Figure 4, wherein, in Fig. 4 204 means that the 4th finishing drilling straight well of its correspondence, in Fig. 4 1600, 1597.7 Deng representing the degree of depth, its unit be m(in like manner, it in Fig. 5 and Fig. 6, is also this expression mode, follow-up repeating no more), because the oil reservoir section on the same level line changes by rule, getting the 4th finishing drilling straight well 204 and the 5th after the oil reservoir section of finishing drilling straight well 205 so, reckoning can obtain the oil reservoir section of the second virtual well 302.In like manner, measuring as shown in Figure 5, second finishing drilling straight well 202 and the 3rd after the oil reservoir section of finishing drilling straight well 203, also can dope the oil reservoir section of the first virtual well 301.
After the oil reservoir section that obtains the first virtual well 301 and the second virtual well 302, also just can dope the oil reservoir section of the horizontal segment of horizontal well to be measured as shown in Figure 6.
The structure in structure work area, determine near the straight well of having set up horizontal well, and then the straight well of the finishing drilling based on determining is set up virtual well, then carrys out the oil reservoir section of the horizontal segment of prediction level well.The oil reservoir developmental state of horizontal segment that later just can be based on this prediction level well at the oil reservoir section of the horizontal segment of having determined horizontal well, thereby the effective design and implementation of Guidance Levels well, for example, can determine according to the oil reservoir section of prediction the structure situation of target zone, the developmental state of oil reservoir, and reservoir is every the distribution characteristics of interlayer, can effectively determine that horizontal segment is in underground position etc., the oil reservoir of well of improving the standard bores encountering rate, the horizontal well yield of assurance, for the design and implementation of horizontal well provides effectively and foundation intuitively.For example, can be according to the oil reservoir section of the horizontal segment of definite horizontal well, dope the structure of horizontal segment of horizontal well and the developmental state of oil reservoir; Then, according to the structure of horizontal segment of the horizontal well of prediction and the developmental state of oil reservoir, just can effectively determine the enforcement track of horizontal well, wherein, the parameter of the enforcement track of horizontal well can comprise following one of at least: the degree of depth that hole angle, horizontal segment are laid, azimuth etc.The enforcement track of so-called horizontal well can comprise, horizontal segment from which position starts to arrange, and the hole angle etc. that what kind of degree of depth or what angle are set.Yet, it should be noted that the above-mentioned cited included parameter of enforcement track is only an example, the invention is not restricted to this, can also comprise that other is used to indicate the parameter information that horizontal well is implemented,
The example of disposing below in conjunction with the horizontal well of a reality illustrates the effect of above-mentioned horizontal well Geological Prediction method:
The reservoir buried depth in certain oil field is 1918～2065m, and the high-order bit oil reservoir is grown thicker, and to limit section oil reservoir attenuate, the average thickness of oil reservoir is 13.5m, is the lithology structural oil pool.21 mouthfuls of oil wells are arranged in this oil field region, yet straight well is because its production effect is poor, only 1 mouthful of well is normally produced, and other well is all closed down.
Therefore, in this oil field region, dispose horizontal well, horizontal section length is 320m.Yet horizontal well deployment district's drilled well is less, the control degree of well is lower, disposes the nearest finishing drilling straight well of horizontal well 118m.The oil reservoir section of the horizontal segment by above-mentioned horizontal well determines that method disposes horizontal well, utilizes the finishing drilling straight well to set up 2 mouthfuls of virtual wells, establishes the prediction section of this horizontal well by virtual well, and implements to the concrete enforcement track of horizontal well.The terminal level well successfully enters target, and horizontal segment is implemented smoothly, and the horizontal segment oil reservoir bores encountering rate and reaches 95%, and well production capacity after coming into operation is higher.
