分析沁水盆地南部深煤层的储层地质特征,认为深煤层压裂的难点主要体现在:难形成有效缝网、储层伤害严重、难反排及支撑剂输运困难。为解决上述难题提出了三项技术对策。 This paper analyzes the reservoir geological characteristics of deep coal seams in the southern Qinshui Basin. It is considered that the key problems of deep seam fracturing are that it is difficult to form effective seam network, serious damage to reservoirs, difficulty in rearrangement and proppant transport difficulties. To solve the above problems put forward three technical countermeasures.
