油气田地质灾害是地质灾害的一种特殊类型。是指在特定的地质背景下因勘探、开发和利用油气资源的工程活动而诱发形成的灾害性地质事件。油气田地质灾害具有诱发性、突发性、成因多样性、可预防性和日趋显著性等特征。对油气田地质灾害分类尚未形成一致的认识,可按灾害的载体和外在表现、空间分布状况、分布范围及动力作用等多种因素进行分类。油气田地质灾害的形成机制是复杂的、多种多样的,主要有构造动力形成机制及非构造动力形成机制两大类。油气田地质灾害受地应力、油气地质环境及工程活动等多方面因素的控制和制约。对其防治应遵循油气田勘探开发与灾害防治并重等原则,深化地质研究,采取适当监测手段,并制定合理的油气资源勘探开发方案,将油气田地质灾害防患于未然。同时还应对油气田地质灾害进行有效预测预报以及恰当评估。 相似文献

The organic matters within the Paleocene Aaliji and Kolosh Formations in the well TT-04, Taq Taq Oil Field in Kurdistan Region, NE Iraq have been studied optically and also analytically by means of pyrolysis, Gas Chromatography (GC), and Gas Chromatography/Mass Spectrometry (GC/MS). Amorphous organic matters seemed to be the dominant component of the extracted organic matters within the studied section with an obvious increase of the Phytoclasts at the upper part of Kolosh Formation. Thermal Alteration Index, vitrinite reflectance, pyrolysis, and gas chromatography data all indicated the maturity of the lower part from the studied layers (known generally as Aaliji/Kolosh) and within the early stages of oil generation. Oil–source correlation indicates the possibility of contribution of the Paleocene source rocks in generating the accumulated oil in the Eocene Pila Spi reservoir in the field which also appeared to be a mature and of marine-to-mixed carbonate source. Oil–oil correlation between the oil in Pila Spi and the oil in the Upper Cretaceous reservoirs showed the possibility of existence of more than one source for the two oils. GC/MS analysis for the Pila Spi oil indicated the effect of biodegradation which may be considered as one of the reasons for being the American Petroleum Institute (API) of this oil about 24° while the oil in the Cretaceous reservoirs is of more than 47° API. 相似文献

Gas hydrates have received global attention as a possible alternative non-conventional energy resource. Hence, the detection, characterization and quantification of gas hydrates are very important for evaluating the resource potential. Presence of gas hydrates in sediments above the bottom simulating reflector or BSR is associated with low attenuation or high quality factor (Q), whereas, free gas bearing sediments below the BSR exhibit high attenuation or low seismic Q. Here the logarithm spectral ratio (LSR) method is applied to marine seismic reflection data along two cross lines (18 and 46) in the Krishna-Godavari (KG) basin in eastern Indian margin, where gas hydrates have already been established by drilling/coring. The interval Qs is calculated for three sedimentary layers (A, B, and C) bounded by the seafloor, BSR, one reflector above and another reflector below the BSR at some common depth points (CDPs) to study the attenuation characteristics of sediments across the BSR. The estimated average interval Q (160) for the hydrate bearing sediments (layer B) is much higher than the average interval Q (80) for both the loose clayey sediments (Layer A) and underlying free gas saturated sediments (layer C). This demonstrates that estimation of seismic quality factor Q can be used for characterization of gas hydrate reservoir. 相似文献

Water development for phosphate mining in a karst setting in Florida—a complex environmental problem
P. E. Lamoreaux 《Environmental Geology》1989,14(2):117-153
The State of Florida, U.S.A., passed legislation in the early 1970s and developed regulations applied to large withdrawals of groundwater. These regulations require strict adherence to defining the impact on surface water, shallow Surficial Aquifers, and the deeper aquifers within the Floridan Aquifer System. These regulations require the development of a Regional Impact Statement and a Consumptive Use Permit. To meet these requirements it is necessary to perform surface- and groundwater studies, extensive pumping tests and the collection of detailed monitoring and water quality data. These permits fall under the jurisdiction of the Florida Department of Environmental Regulations and are administrated under Regional Water Management districts, such as the Southwest Florida Management District. These regional district offices have a regulatory hearing board, hold public hearings that are properly advertized, and have support staffs of geologists, engineers, chemists, and biologists.The Florida Code involved required that, The water crop, in the absence of data to the contrary, is 1,000 gallons per day per acre. A 5—3—1 Criteria also applies that requires that a determination be made to show that there will not be more than a 5 foot average decline in water level in the Floridan Aquifer at the boundary of a property to be developed, not more than a 3-foot decline in the Surficial Aquifer at the boundary, and no more than a 1-foot decline in the nearest water body (pond, lake, etc.). In addition, surface-water flow in streams of the area must not be decreased more than 5 percent unless a variance to the rule is obtained. 相似文献
