The combined production of vertical and horizontal wells can make horizontal well production rates be 2 to 5 times greater than unstimulated vertical well rates, but the areal sweep efficiency is less than that of vertical well pattern untill when the perforation ratio is greater then a certain value, which depends on the pattern of the combination. Seven spot pattern of the combination of vertical and horizontal wells has some advantages over others.
当水平井和直井联合面积布井时,在同样的压差下,水平井的产量要高于相应直井井网的直井产量的2~5倍,但只有当穿透比达到一定程度,或水平井达到一定长度时,其波及系数才高于相应直井井网的波及系数(五点法井网的穿透比界限为0.521,七点法井网的穿透比界限为0.430),因而在水平井开发油气田时,必须保证水平井一定的长度,这样从长远的观点,水平井才能显示出优势,对比性分析表明,水平井和直井的七点法联合布井和直井井网以及水平井和直井的五点法联合布井井网相比,具有一定的优势,数值模拟表明,在水平井和直井的联合面积布井的各种方式中,改进的九点井网是一种较好可取的布井方式。

Torre partially threw up the white flag when he put Miguel Cairo in leftfield in the eighth inning (he also wanted to give Johnny Damon's sore calves a few innings off). The sight of Cairo fighting the sun and trying to run down Mark Teixeira's long drive to left-center in the eighth -- it didn't seem like a fair fight for the career infielder -- kind of summed up the afternoon. The ball fell for a double, one of three on the day for Teixeira (4-for-5, three RBIs, three runs).王建民加油站 D0 f' u7 a- N
当Torre在八局时派Miguel Cairo去守左外野时,已经算是某种程度的举白旗投降了〔他也想让Johnny Damon疼痛的小腿能少用个几局〕,Cairo在八局时试著挡住阳光去追Mark Teixeira打到中左外野之飞球的画面〔当时看起来,对这位当了一辈子内野手的Cairo来说,实在不是一个公平的对决…〕,也算是为今天下午做了个总结,那个球最后落地形成二垒安打,也是Teixeira在这场比赛中打出的三发二垒打的最后一发,他今天五打数、四安打、打回三分、得三分。

The Urban yurt can be a series of roles. It can be a bag when the entire fastenings are enclosed. The sleeves become two pockets at the front. And the stripe can be wired through the loops at the back of the bag so that the Urban yurt can be backpacked. It becomes a coat when the entire fastening of the upper part is opened.
当所有的扣子和拉鍊都接合时,是一个手提包和背包,前方有两各大口袋(当转变为风衣外套时此两各大口袋则是袖子),将带子穿过手提包后的布环则可以变为背包,解开所有的扣子和拉鍊时,是一件风衣外套,此时带子则变成腰带束紧风衣,如此可以使行动较方便也塑造较好的外观。

When the disturbing potential of 1m2/s2 accuracy, or the approximate velocity of accuracy less 2mm/s in the formula of the rotation of the gravity potential is required, the satellite orbit data not satisfied the potential rotation computing demand are rejected from the GFZs Rapid Science Orbit and TUMs ReducedDynamic Orbit. If the disturbing potential is desired 05m2/s2 at satellite track, the satellite velocity required in formula of the rotation of the gravity potential should be recomputed or the GFZs Postprocessed Science Orbit is adopted.
当要求在卫星轨迹处获得1m2/s2精度的扰动位时,也即要求位旋转效应公式中卫星速度的近似精度小于2mm/s时,GFZ的快速科学轨道、TUM的约化动力法轨道只需要剔除那些速度精度不满足要求的卫星轨迹点;当要求在卫星轨迹处获得05m2/s2精度的扰动位时,应当重新估算上述轨道的速度信息,或采用精度更高的GFZ事后科学轨道。

During the motion process, the stagnation and back commutation occur and worsen the performances of circuit breaker. According to the real interruption process, a three-dimensional(3-D) model of arc motion under the effect of external magnetic field is built based on magnetohydrodynamic, which can predict the restriking phenomena. With air vents opened to 60%, the restriking phenomena occur under 3mT magnetic field; when the magnetic field is increased to 5mT, the restriking phenomena disappears.
