美国法尔韦油田位于东得克萨斯盆地中心附近。油田发现于1960年,同年投入生产。原始地质储量为4亿桶,至2003年累计产油2.17亿桶。原油具挥发性,接近饱和。主要储层为下白垩统James组礁石灰岩,主要为骨架粒状灰岩/泥粒灰岩和富含双壳类粒泥状灰岩,各岩相的平均孔隙度一般在7%～11%,但平均渗透率在各岩相中不均,最高达(37～44)×10-3"m2。介绍了该油田的勘探史,描述了盆地构造演化史、含油气系统、地层沉积相和储层特征。
The Farwana Field in the United States is located near the center of East Texas Basin. Oilfield was discovered in 1960 and put into production in the same year. The original geological reserves of 400 million barrels, to a total of 217 million barrels in 2003. Crude oil is volatile, close to saturation. The main reservoir is the Lower Cretaceous James Group reef limestone, which is mainly composed of framework granular limestone / limestone and bivalve-rich limestone. The average porosity of each lithofacies is generally 7% ~ 11% However, the average permeability is uneven in all facies, up to (37 ~ 44) × 10-3 m2 m2. The exploration history of this oilfield is introduced, and the tectonic evolution history, petroleum system, sedimentary facies and Reservoir characteristics.
