Геологическое строение и перспективы нефтегазоносности северо- западной части Денгизкульского поднятия

Аннотация

Subjects of research: Jurassic carbonate oil and gas deposits formations north -western part of the Dengizkul lifting. Purpose of work: A detailed study of the geology of the Jurassic carbonate deposits of the northwestern part of DengizKul lifting, identification of new boundary field, identifying patterns of lateral and vertical distribution in the context of oil and gas collectors, building an updated geological and geophysical model of the studied deposits with an assessment of involvement in the development of additional horizons. Methods of research: A comprehensive analysis of the materials of geological and geophysical studies in conjunction with the data of deep drilling, testing, well logging, seismic exploration. The results obtained and their novelty: A new geological model of Shady field, built on top of XV- HP -horizon, basis on the of 3D seismic data and application partitioning ritmostratigraphy section, justifying the distribution of additional reservoirs in the contract territory and outside its area. Practical value: Estimate was made the possible additions to reserves. According to seismic data in 3D Northwest Dengizkul lifting identified and assessed the prospective resources, located outside the current boundary gas-bearing deposits. Identify the types, quantities and location of further exploration, presents a preliminary economic assessment of the involvement of the identified cost-recovery in development. Degree of embed and economic effectivity: Methods ritmostratigraphy section for dissection for many fields of Uzbekistan and can significantly improve the accuracy of the stratigraphic subdivision of the deposits. The financial cost of additional recommended to test recovery not significant in comparison with the planned growth. Field of application: Oil and gas industry of Uzbekistan, the company engaged in exploration and prospecting of oil and gas.
