Research Of Three-dimensional Area Of Sand Inside The Body Conformation In The Western Of Sulige Gas Field

Western Regional gas field area of about11700km2, over Paleozoic Xiashihezi box8and Shanxi mountain a gas-based, and explore Paleozoic Box4, Hill2, etc. strata, the mainlayer8segment braided river delta, mountain one segment of delta system. West gas field iscurrently being implemented overall development of horizontal wells, horizontal wells bitdeployment need to clarify the exact structure, sand, effective reservoir containing gasdistribution based on the fine description. Based on176West Sulige gas wells andsedimentary core fine description of this analysis, the original seven small layer subdividedinto14sedimentary units. Then deposited on the basis of the use of sub-layer fine contrasttechnology to establish a system of uniform standards for the region’s high-resolutionsequence stratigraphic framework. At the regional sedimentary background analysis andcoring well established on the basis described in two-phase two-phase18sub-micro-phase5phase9rock facies types of energy, the use of fine reservoir description technology, fineportrait of a sedimentary characteristics of each sedimentary unit. Study area in box8timesthicker belt under the plane separated by a four sometimes and sometimes combined with theaqueous composition of the water system, the vertical by at least three vertical cut stackedchannel sandstone, superposition. On the vertical five kinds, flat belt superimposed on thefour kinds of modes and their thickness characteristics are described and demonstrated. Theriver with internal structure and distribution patterns were analyzed sandwich, preferablyhorizontal wells deployment favorable area basis.
