Geological Analysis And Study Of Logging Technical Evaluation For Beach-bar Sand Reservoir

In recent years, with the oil exploration and development to further increase the difficulty, exploration and development focus has gradually moved from conventional sandstone reservoirs, and gradually to complex reservoir lithology tilt, especially thin interbedded carbonate rock reservoirs, practice shows that the thin interbedded layers of oil and gas reserves are considerable, accurate identification and evaluation of thin interbedded layers for increased oil and gas exploration and development is a very important benefit.Papers study area for the four sand beaches Dongying Hollw sandstone reservoir dam, the reservoir is low porosity, low permeability reservoirs and more development of thin alternating layers. For years, Reservoir evaluation in the logging area and the thin layer of evaluation have always been regarded as a difficult problem.For beach sand dam reservoir logging evaluation research, this paper will introduce the the area in Boxing with the significant feature of beach-bar sand reservoir. First, I would like to began forming on the beach bar sandstones and characteristics are described by using the drilled core,the imaging logging and the high resolution of the imaging logging which are based on the primary data included core analysis, geological logging and test logging and so on.Based on a wide range of collection, analysis of geological, logging, testing, laboratory analysis and other informations, I analysised and studied comprehensively the logging response characteristics of different lithology and different thickness by appling comprehensively all kinds of logging data. Based on analysisded and studied the sand beaches four sand dam reservoir, I established the reservoir quality classification criteria and studied the effects of such an effective evaluation method of logging reservoir to provide an accurate calculation of reserves reservoir parameters. These will provide an important basis for the development of such reservoirs in the future.
