哈里伯顿 实施定点压裂技术
斯伦贝谢 多级压裂
贝克休斯 裸眼封隔器组合分段压裂
必捷公司 封隔器多层压裂技术,连续油管压裂
请问:这些新技术在国外页岩气中是否得到运用?各自都有什么典型事例?

斯伦贝谢 多级压裂 (StackFRAC) = 贝克休斯 裸眼封隔器组合分段压裂(FRAC POINT)= 必捷公司 封隔器多层压裂技术(DirectStim).
这三家公司的技术极其类似, 基本可以认为是同一套技术

你说的可能是这个
Multiseam pinpoint hydraulic fracturing.
One of the most significant enabling technologies for CBM in recent years involves technologies that enable the hydraulic fracturing of multiseam completions. Another fracture stimulation option for multiseam completions (not involving coiled tubing) is the conventional “Perf & Plug” method using conventional wireline perforating and composite bridge plugs that set quickly and are easily drilled out at the end of the completion. Using coiled tubing, there are several new methods for isolating and fracturing individual coal seams, some of which involve hydra-jet perforating. These methods were developed to minimize or eliminate non-productive time by planning the entire completion to be performed in a single trip. Coiled tubing fracturing technology allows placement of 30,000 to 100,000 lb/proppant per coal seam With pump time of about 1 hr/seam, three to seven stages have been successfully treated in a single day. For shallow CBM wells, as many as 24 intervals in two separate wells have been fracture stimulated in a single day with the same crew and equipment.

天然气的价格与技术的关系好像没有那么关联
主要还是这次经济危机的影响
能源市场的变化比较大,石油是个政治的问题,价格的变化也很大;
天然气应该是需求的问题吧

就北美油气市场而言, 原油是INTERNATIONAL COMMODITY,价格受国际政治/经济/供求等多方面因素影响, 而天然气是LOCAL COMMODITY. 基本可以认定为只受供求关系影响, 最近几年由于SHALE GAS的技术突破, 产量倍增, 美国又原来的主要消耗和进口大国再向天然气出口国方向快速转变. 彻底改变了北美天然气市场的格局, 造成了天然气价格的暴跌
