Theequivalence percolation resistance law is accurate enough to be used in productivitycalculation of horizontal well pattern.(3) Productivity of mixed well pattern of horizontalwell or multilateral horizontal well and vertical well is constructed and formulae are simpleenough to be used in the oilfield. The patterns include 5-spot pattern,7-spot pattern and9-spot pattern.(4) Productivity formula of united rectangular well pattern of horizontaland vertical wells is constructed. By this formula, the calculation results show that fora horizontal well length, there is a shape factor at which the productivity of the patternis biggest. So optimum method of the well pattern is proposed.(5) A new concept ofdimensionless length of horizontal well is advanced and the relationship of optimum shapefactor of the rectangular well pattern against dimensionless length of horizontal well ispresented. The influences of length of the horizontal well, area of the well pattern unitand the thickness of reservior are concerned.

Results The highest drug use frequency was biguanide. There was 50.9% in the oral antidiabetic drug combination. Leading the first 3 places on the list of drug combination were sulfonylureas in combination with biguanide, sulfonylureas in combination with α-Glycosidace inhibitor, biguanide in combination with α-Glycosidace inhibitor, while there was 16.1% in 3 kinds combination. When oral antidiabetic drugs were combined with other drugs, combination with antihypertensives drugs led the fist, while with antihypertensives drugs led the second.

One has proved that the viewpoint that the horizontal sidetrack is the most important technology for exploiting "large scale"unswept remaining oil in mature oilfields from three aspects.They are:(1) the horizontal sidetrack is the main technology for exploiting primary rich areas of"large scale"unswept remaining oil in mature oilfields;(2) the horizontal sidetrack can hit any rich area of"large scale"unswept remaining oil in reservoirs;(3) the cost of the horizontal sidetrack is more low in contrast with the vertical well and the conventional horizontal well.
从三方面论证了侧钻水平井是开采成熟油田&大尺度&未波及剩余油最重要的技术这一观点:①侧钻水平井是开采成熟油田&大尺度&未波及剩余油主要富集区的主要技术;②侧钻水平井可钻达油层中任何部位的&大尺度&未波及剩余油富集区;③侧钻水平井比钻垂直井和常规水平井费用低得多、更加经济。

Based on the horizontal and vertical combination in formal contexts, this paper defines the independent or consistent contexts and lattices in attribute field; and also defines the horizontal addition operation between contexts or concepts and the horizontal union operation between concept lattices. In addition, we prove that the concept lattice of subcontexts horizontally combined is isomorphic to the horizontal union of sublattices of these subcontexts.

Meanwhile, on the basis of simulation model, the paper introduces the concepts of the combination of ship types, combination of berths, hectometer coastline throughput capability and coastline utilization ratio. By using curve fitting, the function between Tw/Tb and hectometer throughput capacity is achieved. Further more, the analysis of the optimal and suboptimal ship types combination and berths combination correspond to the fixed coastline and the optimal coastline length to the fixed ship types combination and berths combination is obtained.

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。
