摘要

鄂尔多斯盆地东缘致密气储量丰富，但储层压力系数低、物性差、黏土矿物等敏感性矿物大量赋存、孔隙结构复杂，导致储层潜在损害程度较高，制约了气井高产稳产。为了明确研究区致密气储层敏感性特征，以二叠系山西组1段、石盒子组8段致密砂岩为研究对象，利用铸体薄片、扫描电镜、X射线衍射和岩心流体驱替实验等手段开展了储层敏感性实验研究，并提出了针对性的储层保护对策。实验结果表明：研究区岩石类型为细—中粒岩屑砂岩，黏土矿物占比平均为21.59%，以伊蒙间层为主；储层孔隙主要类型为剩余粒间孔与次生溶蚀孔，纳米孔发育，且微—纳孔缝连通性差；盒8段岩心中值孔隙度为6.43%，中值渗透率为0.149×10

-3

μm

；山1段岩心中值孔隙度为6.46%，中值渗透率为0.387×10

-3

μm

；地层水pH值介于5.47~6.83，平均总矿化度为118 077.21 mg/L。研究区气藏属低温、低压致密气藏，具有弱速敏、弱—中等偏弱水敏、弱—中等偏弱盐敏、中等偏弱—中等偏强酸敏、弱—中等偏强碱敏、中等偏强—强应力敏感的特点。平均临界流速为0.3 mL/min，临界矿化度为60 000 mg/L，平均临界pH值为7.79。开发过程中应关注储层低压、低温、纳米孔占比高等特点，着重考虑酸敏、碱敏和应力敏感，并在钻完井、压裂和生产制度中进行完善与优化。研究结果对低压致密砂岩气高效开发具有指导意义。

Abstract

The eastern margin of the Ordos Basin is rich in tight gas resources. However

the reservoirs are characterized by low pressure coefficients

poor physical properties

a high concentration of sensitive minerals such as clay minerals

and complex pore structures. These features result in a high degree of potential reservoir damage

which constrains stable and high gas production. To clarify the sensitivity characteristics of tight gas reservoirs in the study area

the study used tight sandstones from the first member of the Permian Shanxi Formation (Shan-1 member) and the eighth member of the Permian Shihezi Formation (He-8 member) as the research objects. Cast thin-section analysis

scanning electron microscopy (SEM)

X-ray diffraction

and core fluid displacement tests were employed to investigate reservoir sensitivity. Based on the results

targeted strategies for reservoir protection were proposed. Experimental results indicated that the reservoir rocks were fine to medium grained lithic sandstones

with an average clay mineral content of 21.59%

primarily consisting of mixed-layer illite-smectite. The main pore types were residual intergranular pores and secondary dissolution pores. Nano

pores were well-developed

with poor connectivity between micro- and nanopores. In cores from the He-8 member

the median porosity and permeability were 6.43% and 0.149 × 10

-3

μm

respectively. In cores from the Shan-1 member

the median porosity and permeability were 6.46% and 0.387 × 10

-3

μm

respectively. The pH values of the formation water ranged from 5.47 to 6.83

with an average total salinity of 118 077.21 mg/L. The reservoirs in the study area were low-temperature

low-pressure tight gas reservoirs

exhibiting weak velocity sensitivity

weak to moderately weak water sensitivity

weak to moderately weak salt sensitivity

moderately weak to moderately strong acid sensitivity

weak to moderately strong alkali sensitivity

and moderately strong to strong stress sensitivity. The average critical flow velocity was 0.3 mL/min

the critical salinity was 60 000 mg/L

and the average critical pH value was 7.79. During development

attention should be paid to the low pressure

low temperature

and high nanopore proportion of the reservoirs. Acid sensitivity

alkali sensitivity

and stress sensitivity should be prioritized

and improvements and optimizations should be made in drilling

completion

fracturing

and production practices. The research findings provide significant guidance for the efficient development of low-pressure tight sandstone gas resources.
