摘要
研究鄂尔多斯盆地靖边气田统五井区主力产层马五13的储层特征及主控因素。该区五13沉积于潮上带和潮间带上部,岩性为膏核、膏模细粉晶云岩及泥-细粉晶云岩,储集空间为膏模膏核溶蚀孔洞、晶间溶孔、晶间孔、溶蚀缝,主控因素为成岩作用、小幅度构造、古沟槽。靖边气田整体为低孔低渗气田,综合各项物性参数评价该储层为Ⅱ类储层。
Based on the observation of drill samples and laminas, combined with mercury penetration material, the reservoir characteristics and key control factors of principal producing formation Mawu1^3 in the Ordos basin Jingbian （Jb） gas field, the research shows that formation Mawu1^3 deposits in the supratidal zone and upper part of intertidal zone. Lithology characters are gypsum concretion, gypsum-concretion to crystal-powder dolomite and mud-crystal powder dolomite; accumulate spaces are gypsum concretion, gypsum concretion corrosion pores, intercrystal dissolved pores, intercrystal pores and corrosion cracks; master control factors are diagenesis, low amplitude structure and paleogroove. The reservoir of Jb low permeability and low resistivity gas field is estimated to be the second level reservoir according to the physical property parameters.
