神府区块深部煤层气资源丰富，全区域深煤层可压性评价是实现储层有效改造的重要基础。以神府区块8+9号煤层为研究对象，根据测井、试井和排采等数据，分析深部煤储层的力学性质和地应力特征，建立储层可压性评价指数，对比分析了不同可压性储层生产特征。结果表明：① 研究区8+9号煤层静态弹性模量为7.5 GPa，静态泊松比为0.35，动态弹性模量平均为6.3 GPa，动态泊松比平均为0.37，区域分布差异较大；② 8+9号煤层垂向应力介于25.1～54.8 MPa，平均为49.1 MPa，最大水平主应力介于20.4～45.2 MPa，平均为39.5 MPa，最小水平主应力介于17.5～40.8 MPa，平均为33.8 MPa，水平主应力差介于2.9～6.8 MPa，平均为5.7 MPa；③ 由煤层动态弹性模量、动态抗拉强度、动态抗压强度、动态泊松比、水平主应力差以及顶底板–煤层最小水平主应力差综合计算出可压性指数，8+9号煤层的可压性指数介于–12.1～17.6，划分为6类储层，其中以Ⅰ类、Ⅱ类、Ⅴ类储层分布较广。气井开发效果显示，在其他条件类似前提下，可压性指数越高，煤储层改造越充分，产气效果越好；但是，神府区块深部煤储层力学性质、地应力和可压性平面分布格局较为复杂，需要详细甄别以制定针对性压裂改造方案。建立的深部煤储层可压性评价方法，可为深部煤层气储层分类改造和高效开发提供依据和指导。

The deep coal reservoir resources are abundant in the Shenfu block, and conducting the evaluation of deep coal seam fracability in the whole region is an important foundation to realize effective reservoir reconstruction. The No.8+9 coal seams in the Shenfu block are taken as the research objects. Based on the data of logging, well test and drainage, the mechanical properties and in-situ stress characteristics of deep coal reservoirs are analyzed to establish the evaluation index of reservoir fracability, and different types of reservoirs and their production characteristics are compared and analyzed. The results show that: ① The static Elastic modulus and static Poisson’s radio of No.8+9 coal seams in the research area are 7.5 GPa and 0.35, respectively. And the average dynamic Elastic modulus and dynamic Poisson’s radio of No.8+9 coal seams are 6.3 GPa and 0.37, respectively, with significant regional distribution differences. ② The vertical stress of No. 8+9 coal seams ranges from 25.1 to 54.8 MPa, with an average of 49.1 MPa. The maximum horizontal principal stress ranges from 20.4 to 45.2 MPa, with an average of 39.5 MPa. The minimum horizontal principal stress ranges from 17.5 to 40.8 MPa, with an average of 33.8 MPa. The difference in horizontal principal stress ranges from 2.9 to 6.8 MPa, with an average of 5.7 MPa. ③ The fracability index is calculated by the dynamic Elastic modulus, dynamic tensile strength, dynamic compressive strength, dynamic Poisson's ratio, horizontal principal stress difference of coal, and minimum horizontal principal stress difference between the roof and floor of the coal seam. The fracability index of No.8+9 coal seams is between−12.1−17.6, which can be divided into 6 categories. The No.8+9 coal seams have a wide distribution of Class I, Class II and Class V reservoirs. The development effect of gas wells shows that under other similar conditions, the higher the fracability index, the more complete the transformation of coal reservoirs, and the better the gas production effect. However, the mechanical properties, in-situ stress, and compressibility of deep coal reservoirs in the Shenfu block are distributed in a complex plane, and it is necessary to carefully identify and develop targeted and appropriate fracturing transformation plans for segmented areas. The evaluation method of deep coal reservoir fracability is established to provide a basis and theoretical guidance for reservoir classification and transformation and the efficient development of deep coalbed methane in the study area.
