宝浪苏木构造带所属的宝中和宝北两个含油气区块 ,属于特殊的低孔低渗透储集类型。它与东部的许多低渗透油气藏相比 ,具有岩性偏粗 (含巨砾 ) ,以不等粒砂岩和含砾不等粒砂岩为主 ,占 78.41 % ;矿物成分成熟度和结构成熟度较低 ,颗粒破碎严重 ,粘土矿物 (尤其是高岭石 )和地层微粒含量较高 ,储集层主要渗流通道为 1～ 6.3 μm(体积占 2 5 .88% ,却提供了67.2 1 %的渗透率贡献值 ) ,以特低 -低渗透中孔细喉不均匀型储集层为主。地层水阳离子变化幅度大 ,为 680 1～ 3 4788mg/ L;水型复杂 ,地下流体性质纵、横向上非均质性明显 ,油气层伤害严重 Baolang Sumu tectonic belt belongs Baozhong and Bao North two oil and gas blocks, belonging to a special low-porosity and low permeability reservoir type. Compared with many low-permeability reservoirs in the east, it is lithologically coarse (including boulders), accounting for 78.41% of the total, with unequal sandstone and gravelly sandstone, mineral composition and structural maturity The fractures of the reservoirs are mainly composed of clay minerals (especially kaolinite) and fine layers of particles. The main seepage channel in the reservoir is 1 ~ 6.3 μm (25.88% by volume, but 67.2% Permeability contribution value), with a special low-low permeability medium-sized throat heterogeneous reservoirs. The variation of cation in formation water is large, ranging from 680 to 3 4788 mg / L. The water type is complex, and the vertical and horizontal heterogeneities of subsurface fluid are obvious, and the formation damage is serious
