A shale gas, sichuan province development present situation:
Shale gas rich resources to identify due to its attenuation faster, mining cost is higher, although 50 s have found shale gas, but there is no exploration has been using. At present, the domestic shale gas to set up the independent minerals, and actively promote shale gas exploration emphasis on development and utilization.
Shale gas mainly domestic had yet to systematic exploration evaluation, in early 2012, the ministry of land and resources estimates that domestic shale gas mainly for 2.5 billion cubic meters. Although domestic whole resources rely mainly on the theory, but in sichuan oil and natural gas have had preliminary exploration evaluation. At present shale gas recoverable resources of sichuan for 12 trillion cubic meters, shale gas reserves of natural gas in the conventional ambitious.
Second, sichuan shale gas development initial results, the future looks more optimistic:
In the current oil in sichuan has 7 10 Wells, drilling is three mouth. Shell oil and development cooperation in areas has 7 5 mouth, and have sales qualification. At present, shale gas production changning vying demonstration zone has been set up and is expected to become the domestic shale gas exploitation of the important reference standards. In the current oil has more than 500 cubic meters of realization of sales.
"1025" period, oil and sinopec plan in mining production shale gas more than 20 trillion cubic meters, according to the current exploration situation, the enterprise to realize the scale relatively optimistic and mining as to realize breakthrough.
Three, the enterprise to shale gas mining enthusiasm
At present many enterprise show for shale gas development will. According to the energy bureau introduced in oil and gas leadership, many enterprises to sichuan province to shale gas inspection. Sichuan HongHua group also plans to vote in sichuan and set up a joint venture company, the common participation in resources development area. And in the current oil shale development joint ventures with foreign sinopec spirit already smoothly. In the rich in oil shale gas in yongchuan have sales. In addition, the shale gas for domestic development provides technical services, and equipment of the foreign capital enterprise very much service.
From the domestic enterprises to participate in the form of shale gas to see, investment in equipment, investment and service team for resources will become important means. Shale gas and because of its wellhead density bigger, to the well drilling and completion service demand is bigger. And because of its large oil and gas enterprise personnel, would be difficult to support large-scale service needs. Therefore the future drilling service requirement or become a bottleneck.
Four, shale gas development will drive high-horsepower fracturing equipment needs
Domestic shale gas and the mining conditions of the difference is very big. Not only has the difference of geological conditions, surface condition the difference is bigger. Shale gas resources as the country of surface more for hills, town, and domestic shale gas development face lower fracturing of the demand for train cover an area of an area is particularly urgent. At present HongHua group are developing the 6000-horsepower fracturing pump to visit investors more surprised. According to information, this fracturing pump have been in the United States OTC fairs, still in commissioning phase.
Five, short-term shale gas fields as private enterprise Co., LTD
Although the enterprise and government departments for shale gas development is very good, but at present the institutional obstacles and not fully lifted.
First, the enterprise and energy board leadership introduces, although shale gas become independent mineral, but for shale gas management method has not yet come. Because of the high quality shale gas resources in sichuan and conventional gas coincidence, therefore, the second round of bidding shale gas blocks from the current understanding is the basin edge areas. Therefore, the enterprise are also waiting for the future for the detailed rules for the implementation of the shale gas management to come. Second, natural gas transport pipeline is still in state monopoly. Therefore, unconventional natural gas through a central pipe genotype market pricing is difficult. Third, from the current technology master to see, the domestic exploration and drilling, horizontal Wells is comparatively mature technology, there is no substantial obstacles. At present the long distance, subsection fracturing is difficulty. From domestic to see, because the geological condition is relatively complex, cannot be completely copy of the fracturing technology.
Six, natural gas liquefaction equipment demand
During the 1025 domestic demand for gas will rise fast. Sichuan natural gas production from the current 24 billion cubic meters will rise to 50 billion cubic meters. Domestic gas imports will rise dramatically. From domestic to see, shale gas liquefaction equipment needs bigger, enterprise investment intentions is stronger. LNG station, at present construction force is bigger also, however, the obstacles of air source is security, LNG heavy card change and inadequate infrastructure car costs. From the current level of Maori perspective, we research enterprise feedback is now able to achieve 30% to 40% of the gross margin level, although the fierce competition gradually, but the margin level still a rich.
