勘探

Finding a way of quick and object oriented wavefield extrapolation is significant not only for deep seismic exploration but also for imaging with supertremendous seismic data acquired from noncombination receivers, both highly needed to develop in petroleum prospecting.

快速进行目标区波场延拓对石油勘探中急需发展的深部地震勘探和无组合海量地震数据的成像有重要意义。

Therefore,when the geology risk assessment is done,the geology risk index as effective thickness,porosity,permeability,abundance,exploration maturity,heterogeneity,exploration success ratio and gas combination are selected.Using the gray cluster method,this paper conducts the synthetic evaluation and research on geological risk taking 7 well blocks in a certain region as an example and according to geology risk assessment characteristics,which can quantize and display the quality of nonproducing reserves in each area.

为此，在对地质风险评价时，选取了有效厚度、孔隙度、渗透率、丰度、勘探成熟度、非均值性、勘探成功率、含气组合等8个地质风险指标，以某油田某地区的7个井区为例，结合地质风险评价的特点，运用灰色聚类法对其进行地质风险综合评价研究，使以各个区块为单元的未动用储量的优劣得以量化表现。

Due to a series of large or oversize scale oolitic gas pools were found in Feixianguan Formation in NE Sichuan Basin, the gas exploration have a good prospect. The questions about origin and accumulation of the natural gas in oolitic reservoir have been one of the focus in the field of petroleum geology.

四川盆地东北部飞仙关组一系列大型、特大型鲕滩气藏的发现，显示出该区巨大的勘探潜力和良好的勘探前景，有关鲕滩天然气的成因、来源及成藏等问题，是当前油气地质学研究的热点之一。

It is pointed out that the deep and super-deep reservoirs such as Permian and Triassic in west and east, middle-shallow reservoirs of Triassic continental deposit in east and middle, piedmont zone, Jialingjiang Formation oolitic shoals and regional unconformities are important regions to explore in Sichuan Basin.

通过总结四川盆地大中型气田的分布特征，进一步探讨了盆地勘探发展的方向，指出川东及川西的深层超深层、川东及川中陆相中浅层、山前带、嘉陵江组鲕滩和大型区域不整合等是下步勘探的重点领域。

Three periods petroleum accumulation exists in South-of-fifth-area oil field, the first period oil and gas is the Jiamuhe group mature and high mature hydrocarbon and the Fengcheng group mature hydrocarbon in late Permian to early Triassic, was destroyed in the Indo-Chinese movement intermediate stage, but some still is conserved in good conserved condition, which is one of exploration objects. The second period is the Fengcheng group high mature hydrocarbon in late Triassic to early Jurassic, which is the important exploration target. The third period is the Jiamuhe group overmature dry gas in the late Jurassic Period to the early Cretaceous.

五区南油气藏存在三期成藏，第一期是佳木河组过成熟干气和风城组成熟油气，成藏期在晚二叠世到早三叠世，在印支运动中期被破坏了，但是在保存条件好的地区仍存在这一期油气藏，它是勘探的对象之一；第二期是风城组高成熟油气，成藏期在晚三叠世到早侏罗世，也是勘探的对象之一；第三期是佳木河组过成熟干气，成藏期在侏罗纪到早白垩世。

In recent years, chimney structure has been proved one of important indicators and a useful guide to major petr...

近年来的国内外勘探实践已经证明，烟囱构造是大中型油气田存在的重要标志，已成为油气勘探的首要线索之一。

Junggar basin is one of the main petroliferous one in the west of China. There are abundance oil and gas resources which have been found through exploration for 50 years.

准噶尔盆地是中国西部重要的油气勘探盆地，经50余年的油气勘探，发现了极为丰富的油气资源。

The traditional economic evaluation of oil/ gas exploration projects is a single analysis essentially: either by characterizing the investment return gained from the ex ploration projects, or by weighting the geologic risk borne by the projects.

传统的油气勘探项目经济评价方法基本都是单一的分析：或表征勘探项目所取得的投资收益，或衡量项目所承担的地质风险。

The exploration and development of Huangjindai Oilfield in Liaohe Basin was mainly focused on the intermediate and upper submembers of Es-1, while less attention has been paid to Dongying Formation of shallow layers, lower submember of Es-1 and Es-3 of deep layers. This provides space for potential exploration.

辽河盆地黄金带油田投入勘探开发后，基本上以沙一段中、上亚段为主力勘探开发目标，而对浅层的东宫组和深层的沙一下亚段及沙三段重视不够，为后期的老区挖潜提供了空间。

Since development of volcanic layers and volcanic mounds in basement in Tazhong area, using seismic exploration is usually difficult to acquire better seismic data in the interior of vocatine and below(mainly caused by shield of volcanic layer), but using MT exploration may not produce such problem, because the electromagnetic wave does not suffered from the shield of higher resistance layer; especially the volcanite has the feature of higher magnetic susceptibility and impedance, which provides excellent c...

由于塔中地区的火山岩层及基底火山岩丘发育，采用地震勘探方法通常难以在火山岩内部及其以下获得比较好的地震资料(主要是火山岩层的屏蔽作用)，而利用MT勘探则无此问题，因为电磁波不受高阻地层屏蔽，尤其是火山岩具有高磁化率和高电阻率的特征，从而为在该区应用大地电磁和磁力方法识别火山岩薄层及基底火山岩丘提供了得天独厚的条件。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
